What is a Quality Control Inspection and How to Select a Right QC Inspection Partner in China

 Quality control can be defined as "part of quality management focused on fulfilling quality requirements." While quality assurance relates to how a process is performed or how a product is made, quality control is more the inspection aspect of quality management.Inspection is a major component of quality control, where physical product is examined visually.

A quality control inspection is an activity of checking quality of any product, such as measuring, checking, examining, testing or gauging one or more characteristics of a product and comparing the results with specified requirements in order to establish whether conformity is achieved for each characteristic. The quality inspector usually follows a pre-established checklist that is based on the product specifications. Inspected products can be the components (raw materials) used for production, semi-finished goods, or (most often) finished goods before shipment to a customer.

Why you need a quality control inspection service in China ? 

To answer this question I can share an old story happened to our UK client years ago. He lost more than 120000 USD due to the quality issue in 2011. He placed an order of fitness equipment with a small factory in Yongkang, Zhejiang province. He purchased a sample and confirmed the quality before placing the order, however, the factory used slightly cheaper raw materials to reduce the costs in China during the massive production after the customer placed the order. And unfortunately the customer did not conduct any quality control inspection before loading in China, when he received the defective goods in UK, he found the problem and his end customers rejected the goods, what's more, when he called the supplier for a solution, the supplier did not admit anything as he could not offer enough evidence. 

This is a lesson for every importer and this is the main reason why you have to inspect your shipment first before loading in China for any large orders. Only by inspecting your shipment of goods before it leaves your supplier’s factory can you identify and address any quality issues before it’s too late. With the quality control inspection services, you can well control the quality of your product before production, during-production and before loading. Managing product quality with QC inspection lowers your risk of product returns, unhappy customers and many other costly and avoidable problems

How many types of quality control inspection ?

In case QC inspection is so important, so when shall we conduct the QC inspection? To answer this question, you have to understand the types of QC inspection first

Generally speaking there are 5 types of QC inspection services worldwide, that is: 

PPI - Pre-Production Inspection  

FAI - First Article Inspection  

DPI - During Production Inspection 

PSI -- Pre-Shipment Inspection

CLL--Container Loading Inspection  

but in China customers focus on following three main types of inspection in quality control: 

PPI - Pre-Production Inspection 

DPI - During Production Inspection 

PSI -- Pre-Shipment Inspection

Here are the details: 

PPI- Pre-Production Inspection

The Pre-Production Inspection (PPI) is a type of quality control inspection conducted before the production process begins to assess the quantity and quality of the raw materials and components, and whether they are in conformity with product specifications. This service is important for large orders in China because some unreliable suppliers may try to use cheaper raw materials and components to save costs during massive production.

A typical PPI inspection checklist includes, but is not limited to:

Verifying the raw materials and their conditions.

Inspecting planned storage for your products.

Inspecting a supplier's production readiness and quality plan

Inspecting the function, size, and measurement of raw materials and other components

Making the required reliability and safety tests

Making sure your specifications and sourcing requirements are correctly understood by the factory

Preventing any potential flaws and failure in the mass production 

DPI -- During-Production Inspection 

During Production Inspection (DPI) or otherwise known as DUPRO, is a quality control inspection conducted while production is underway, and is especially good for products that are in continuous production, that have strict requirements for on-time shipments. The During-Production QC Inspection is mainly an inspection of semi-products, stock of raw materials, production process, package requirements, workmanship etc during the production of your order in China.

A during production inspection takes place once 20-50% of your product run has been completed and packed. During a DPI inspection, a quality control inspector will inspect the completed product to ensure that all processes are being followed to the agreed standard. They’ll also look to identify any product deviations or issues early in the manufacturing process.

A typical DPI inspection checklist includes, but is not limited to:

Verifying the supplier follows the requested process and material specifications

Verifying the production and quality plan

Inspecting storage conditions

Inspecting packaging, labeling, and barcodes

Conducting reliability and safety tests

Inspecting semi-finished products

DPI inspections are useful as a quality assurance measure as it ensures that the quality of the products in production is the same as the one you received as a sample. It also gives you chance to make any necessary adjustments and corrections before the production run has ended, which can save you valuable time and money. If defects have been identified, knowing the percentage of finished products with defects also ensures that you have time to plan for them before they are shipped to you.

PSI -- Pre-shipment QC Inspection  

 The Pre-shipment QC Inspection is an inspection of all the finished products, documents, package, shipping marks, quantity etc of your order at the factory. This service shall be performed when the order is 80 -100% completed.This inspection is conducted on finished products when at least 80% of the order has been packed for shipping. This inspection is done according to standard Acceptable Quality Limits (AQL) specs for the product.

A typical PSI inspection checklist includes, but is not limited to:

Verifying the safety and function of manufactured products

Verifying the quality of products

Verifying the order has been produced to the standards set out in the purchase contract

Inspecting the product packing, labeling, and shipping marks etc

Checking the order quantity and the documents related 

A PSI inspection makes sure that the supplier has manufactured your products to your specifications and packed them as required by your purchase contract. PSI inspection is the most popular and important one as you can reduce the risk of receiving defective items.

What is a factory audit service and how to select a best auditing service partner in China

What is a factory audit or supplier inspection service ?  

In China, a Supplier Inspection Service is also called a Factory Audit Service sometimes, it is a kind of detailed company verification services and it is a standardized process used by quality managers or auditors to determine if a supplier or vendor conforms with the required business standards in delivering high quality products and services.

Generally speaking a full factory audit report may cover following parts: 

1.Supplier Details

This is the basic part of the audit report, it will tell you all the basic information about the supplier, covering their full company name, address, staff, facilities, boss, management level, bank account and tax ID etc. 

2.Qualification Audit

This audit is mainly to check out their Export License and other specific certification required. In China, not all the factories have the right to export because they do not have their own export license and every exporter must get an export license from the government first before selling to overseas market, this is why sometimes some factories have to work with a professional export agents in China as they cannot sell to their customers directly. Another important thing is that for some special products, the customers may ask for more qualifications in order to import smoothly, say, ISCC certificate for UCO and biodisel industry in Europe, FDA certificate for medical products in US, HALAL certificate for food products in Middle East etc. Other certificates like UL, CE, FCC etc are also very important for some specific products and areas during international business. 

3.Capability Audit

A capability audit, also called a capability assessment, is an on-site visit to your supplier's (or potential supplier's) facility. This audit is mainly to check out their production capacity, overall company management 

system and facilities etc to make sure they can fully meet your sourcing requirements in China.  

4.Quality Audits

A quality audit, also called a quality assessment, is an on-site visit to a supplier's facility. At that facility, auditors go through a series of checks to help you evaluate the effectiveness of their Quality Management System (QMS). The auditor will measure the effectiveness of the factory's Quality Management Systems (QMS).They'll evaluate them based on the ISO 9001 standard. And you'll come out with a much clearer picture of whether or not there are any quality risks to your supply chain.

5.Social Compliance Audits

A social compliance audit is to verify whether your suppliers or partners are in compliance with universally held norms and local laws related to social responsibility. These audits play an important role in helping to ensure an ethical supply chain. The auditors will verify the working conditions in the factory and to see if they meet defined criteria in the following areas: 

Child Labor

Forced and Compulsory Labor

Health and Safety

Freedom of Association and Right to Collective Bargaining

Discrimination

Disciplinary Practices

Working Hours

Remuneration

Management System

Social compliance audits are generally based on the SA8000 system (SOCIAL ACCOUNTABILITY), which measures social performance in areas that are important to your corporate social accountability.

6.Environmental Audit

An environmental audit is to assess their environmental management system. The audit report will give you a 

clear picture of their practices and helps you determine whether they are an environmentally responsible supplier or not.These audits are generally conducted based on the ISO 14001 family of standards, which are focused on verifying that the supplier has systems to“identify, manage, monitor and control their environmental issues in a holistic manner.” The key focus areas for these assessments tend to be the following:

Air pollution

Water and sewage issues

Waste management

Soil contamination

Climate change mitigation

Efficient use of resources

The assessments are designed for companies that want to develop and maintain a supply chain that is free of problematic environmental issues. Audit criteria are flexible and can be modified to suit the needs of your organization.

7. Security Audits

The Customs-Trade Partnership Against Terrorism (C-TPAT) is an initiative of U.S. Customs and Border Protection (CBP). Its goal is to improve the security of private companies' supply chains with respect to terrorism. Our auditors assess the security and processes of your suppliers on-site to ensure compliance. 

A supplier is evaluated in accordance with C-TPAT standards. These audits generally include the following:

Assessing their physical access controls, including employee access controls, visitor access controls, delivery controls, and procedures for removal of unauthorized persons.

Reviewing their physical security, including fences, gates, parking, building structure, locking devices, alarm systems, and video surveillance.

Assessing their procedural security, including documentation processing, manifesting procedures, shipping & receiving, and cargo discrepancies.

Other items in accordance with C-TPAT requirements.While on the ground at the supplier's facility, our experienced auditors will gather all the information required to determine whether a supplier will meet C-TPAT standards.

Different clients may have slightly different requirements on auditing their suppliers in China.Say, for some Asian clients, they may focus on the Qualification Audit while for some European clients, they ask for Security and Environmental Audits as well. The cost is quite different based on the different audit requirements from the clients worldwide. 

Why do you need a factory audit?

You can't always trust everything your factory says. They can talk big and make bold claims about their facilities, equipment, production capacity, and internal quality control procedures in order to win your business. I remember a case five years ago, a South Africa customer was cheated by a supplier in Tianjin who claimed to be a big manufacturer. The customer lost more than 50000 USD due to the quality issue, when he came to China for a solution, the customer inspected their address and found that they are only a smallest trade company in China. Please keep in mind that according to our experience more than 80% of the Chinese trade companies or agents you meet online or at local trade fairs would like to disguise themselves as a real factory in order to obtain big orders. Some professional scammers use 'fake' export licenses or business licenses to attract foreign clients.Seeing is believing, the best way to check them out is simply to go and inspect them in person with your eyes. Factory (Supplier) Inspection or Auditing Service is so far the best way to find out a long term business partner or a qualified factory in China, esp for OEM services.

Bamboo household paper - creating a healthier life for you and your family!

     

       As we all know that bamboo can thrive naturally without using any pesticide. Scientists found that bamboo owns a unique anti-bacteria and bacteriostatic bio-agent named "bamboo Kun". This substance is combined with bamboo cellulose during the process of being manufactured into bamboo fiber. Under the microscope, you can find out that the bacteria on the wood pulp paper will rapidly reproduce, while the bacteria on the bamboo pulp paper will not only not reproduce, but also die 72% within 24 hours. This is because the "bamboo Kun" in bamboo is a natural bactericidal component, which can prevent insects and stink, inhibit the growth of bacteria and protect the environment naturally.Bamboo fiber has particular and natural functions of anti-bacteria, bacteriostatic and deodorization.

Three simple steps to distinguish the quality of bamboo papers

 There are dozens of bamboo paper brands on the market at present and for lots of citizens it is hard for them to distinguish the quality of bamboo tissues with their eyes and hands as they do feel and look the same. 

The high quality bamboo tissue is made by 100% bamboo pulp while for some cheaper or low quality bamboo tissue, they are made by the mix pulp (bamboo pulp with other pulp during production). Here is a simple way for you to find out the truth regarding their quality: 

Step 1: Prepare two cups of water and two pieces of different quality bamboo paper

Step 2: Pour the cup with clean water and soak the samples into the water for 3 minutes

Step 3: Take out the samples and scrub them on your skin, you will get the results.

Result: The low quality bamboo paper will break into tiny pieces after soaking and scrubbing. Please click the video link below to see how：https://haokan.baidu.com/v?vid=10571619992087039756&tab=recommend

Why do we use bamboo pulp paper instead of wood pulp paper now

Bamboo pulp papers are more bacteriostatic and healthier.
It is a common fact that bamboo can thrive naturally without using any pesticide. Scientists found that bamboo owns a unique anti -bacteria and bacteriostatic bio-agent named "bamboo Kun". This substance is combined with bamboo cellulose during the process of being manufactured into bamboo fiber. Under the microscope, you can find out that the bacteria on the wood pulp paper will rapidly reproduce, while the bacteria on the bamboo pulp paper will not only not reproduce, but also die 72% within 24 hours. This is because the "bamboo Kun" in bamboo is a natural bactericidal component, which can prevent insects and stink, inhibit the growth of bacteria and protect the environment naturally.

Bamboo fiber has particular and natural functions of anti-bacteria, bacteriostatic and deodorization. It is validated by Japan Textile Inspection Association that even after fifty times of washing bamboo fiber fabric still possesses excellent function of anti-bacteria. Its test result show over 70% elimination rate after bacteria being incubated on bamboo fiber fabric.

Uses fast-growing grasses, not trees
Because bamboo and sugar cane are grasses rather than hardwoods, they both grow very quickly and, after harvest, grow back just as quickly – in as little as three to four months (trees can take up to 30 years to grow). No replanting is necessary - unlike trees, which never grow back after being cut down. About 83 million rolls of toilet paper are produced from trees each day.

Kind on the environment
Switching to STIN bamboo paper can help save rainforests, water, and wildlife, and can make a real impact on reversing climate change. Bamboo can grow in environments with depleted soil and little water and actually returns nutrients to the soil, which improves degraded areas. Bamboo also doesn't require fertilizers, insecticides or pesticides. An added and very important benefit is that STIN paper is made from bamboo species that are not food sources for pandas.

The sustainable alternative
Switching to STIN bamboo paper can help you move toward a more sustainable lifestyle. In fact it’s probably one of the easiest things you can do to help the environment in your daily life. If you operate a business, switching to STIN bamboo paper can contribute toward your company’s sustainability goals.

More eco-friendly than recycled paper
Recycling or processing a tree into tissue can take much more water and energy than the minimal processing necessary to turn bamboo and sugarcane into paper. BPA can also be found in recycled tissue after deinking and cleaning recycled paper. STIN bamboo paper is 100% BPA free.
Softer and stronger than recycled paper. Unlike recycled bath tissue, which can be rough or thin, bamboo fibres produce a much softer product than recycled paper. And it’s strong, too – bamboo’s natural qualities make a paper that’s been tested to be stronger than recycled tissue of the same weight.

100% biodegradable
Bamboo bath tissue is 100% biodegradable. It's fibers quickly dissolve back into the earth – making it safe for all septic systems.

The difference between bamboo pulp paper and wood pulp paper

Bamboo pulp paper is getting more and more popular in China due to its healthier and more environment-friendly characteristics. Here are the main differences between bamboo pulp paper and wood pulp paper:
1.Different raw materials
Wood pulp paper generally refers to the paper made of high quality wood as raw material, which is made by beating pulp,cooking and other processes, with fine paper,soft,smooth surface and good toughness. The paper towels made of inferior base paper are rough,loose,porous,and poor expansion intensity, resulting in paper scraps and paper hair left at the wiping place, affecting the use of paper. In addition, the color of tissue made of inferior base paper is not white enough, which often results in excessive use of fluorescent brightener.

Bamboo pulp paper is produced by using bamboo pulp alone or with wood pulp and straw pulp with reasonable proportion through pulping and rinsing and other paper-making processes. The performance of bamboo pulp is between coniferous wood and broadleaved wood, which is obviously superior to that of grass. Pulp, can replace broad-leaved wood pulp and reduce the amount of coniferous wood pulp, used to make a variety of paper, including a variety of high-grade paper products.

2.Bamboo pulp paper is softer
People who are used to bamboo pulp paper know that wood pulp paper is rough. Because the wood pulp itself is relatively loose and rough, the paper holes produced are sparse and many empty, and the expansibility is poor. The drag will leave paper scraps and small fibers, and the long-term use is not friendly to the respiratory tract. The bamboo fiber is flexible and fine, and the paper is more soft and delicate, without paper scraps, which will not cause allergy.

3.Bamboo pulp paper is stronger and more tear resistant
The ordinary wood pulp paper will be damaged once it is touched with water, and the scraps of paper will stick everywhere. Bamboo pulp paper will not leave paper scraps after wiping, even if the whole paper is soaked in water, it can resist pulling to a certain extent, and will not easily break. 

4.Bamboo pulp paper is more environment-friendly and biodegradable
Wood pulp paper-making will consume a lot of forest resources. The total amount of wood consumed in papermaking is 10 million cubic meters per year, which can fill the whole west lake. Forest regeneration is very slow, which leads to the consumption of more forest resources. Bamboo grows very fast. The fastest bamboo can be made into bamboo in only two months, and can be regenerated within three years after cutting. It is a recyclable paper-making material.

As a regenerated cellulose fiber; bamboo fiber is 100% made from bamboo through a high-tech process. The raw material bamboo is well-selected from non-polluted regions in Yunnan and Sicuan Province, China. They are all 3-4 years old new bamboo, of good character and ideal temper. The whole distilling and production process is a relatively green process without pollution. China is the country with the most abundant bamboo resources in the world. In terms of plantation area, China's bamboo forest area is about 5.5 million Hm2, ranking the first in the world. In terms of species, there are 48 genera and more than 500 species of bamboo in China. Among them, small miscellaneous bamboo, Moso bamboo, Dayuan bamboo and depigmentated bamboo are commonly used in the paper industry, which are widely distributed in Sichuan, Jiangxi, Zhejiang and other provinces.

How to make bamboo pulp ?

Bamboo pulp making can be simply classified into materials preparation, pulp cooking, pulp washing and pulp bleaching

Materials Preparation
Due to the seasonality of bamboo cutting, for ensuring the continuous production, the pulp mill must stock a certain amount of bamboo. Generally, the bamboo storage capacity should be used for 3-6 months. New bamboo should be dried by the air and de-greening. As for the stacking and unstacking of the bamboo bundle, portable belt conveyor and loader will be the best helper.
After bamboo bundle enters the pulp mill, it is cut into bamboo chips by the bamboo cutter and is stored with other chips. The size of bamboo chips is 10-25mm.

When the bamboo is stored in the open system, the position in the process should be designed according to the principle of first screening and last storage. This kind of principle can remove the bamboo sawdust from the screening bamboo chips. The fermentation and mildew of bamboo chips are avoidable in the storage of bamboo. The qualified bamboo chips are sent to storage. The long bamboo will be back to bamboo cutter and sawdust will be used as waste and burned in the boiler. The stored bamboo chips are used in according with the first-in-first-out principle. Ensuring the full use of bamboo chips and avoids the stored bamboo chips go bad because of long-term storage. It is necessary to wash bamboo chips in the process of materials preparation. Remove the loam among the bamboo chips, which reduce the wearing, scaling of paper pulper and silicon interference.

Bamboo Pulp Cooking
The qualified bamboo chips in the preparation through the conveyor enter into the pulper. After bamboo feed into pulper, pour the black liquor from the bottom of pulper, presoak the bamboo chips, and remove the air from the bamboo chips. Use the high-temperature black liquor and hot white liquor displace the black liquor in the pulper. Control the temperature in the pulper up to 145℃, and heat the pulper with steam, raise the temperature to the cooking temperature and keep it. When the reaction reaches the settled H factor, send the warm and weak black liquor of pulp washing process into the bottom of pulper, displace the high-temperature black liquor and reduce the temperature in the pulper to 100℃. For bamboo pulp making, it generally adopts kraft process. The kraft process has high digester yield, high strength, less pollution, soft fiber, and mature technology of alkali recovery. Compared to the wood, the bamboo is easier to cook because of its composition. The paper pulper machine adopts the vertical and continuous pulp digester. In general, the cold blow is typical choice, it not only recovery the rest heat, but also avoid the leakage of flue gas. Besides, reduce the steam consumption and pyrolysis of pulp, improve the strength of the fiber. In the real bamboo pulp processing, due to the dense structure of bamboo and the difficulty of air removing in the conduit, bamboo pulp cooking require longer penetration time. Penetration time for raising temperature is 1.5-2h, penetration time for keeping temperature is 2-2.5h. As we all know, there are vertical pulper and horizontal pulper. Different specifications of pulpers for bamboo pulp making as below:

Bamboo Pulp Washing and Screening
The practice has proven that bamboo fiber is long, and it has good drainability. The bamboo pulp is easier to wash compared with other straw pulp, even the hardwood pulp. The common equipment for bamboo pulp washing process includes vacuum washer, pressure pulp washer, and Horizontal belt filter. Generally, the large-scale bamboo pulp production line can use twin roll press or DD washer. Vacuum washer is more suitable in overall consideration.Bamboo pulp screening and cleaning mainly remove the crude residue, dust, sand. Bamboo pulp making will produce a lot of crude residues, they are the knots that are not cooked sufficiently. These crude residues are not suitable to cook or produce a bad influence on the bamboo paper quality. The bamboo pulp washing adopts multi-section countercurrent washing can efficiently extract black liquor and ensure the alkali recovery. The bamboo pulp adopts close screening system, screening concentrations are 2-3%. This type of technical combination save water, reduce the pollution and require less treatment of slurry-residue.

Bamboo Pulp Bleaching
The pulp bleaching is used to improve the pulp whiteness, keep the strength of bamboo pulp and reduce the pollution. Because the oxygen delignification and medium consistency technology mature gradually, bleaching process is the short process with 3-4 stages. To meet the strict requirement of environmental protection, bleach agent uses chlorine dioxide to replace. As for the choice of bleaching, there are ECF, TCF, EPP, ZXP, TCF, ECF, CEH, and etc. Currently, the ECF is still the best popular and efficient pulp bleaching process. But from the economic considerations, CEH is more applicable.

Advantages of Bamboo Pulp
Bamboo pulp has medium-length fiber, so it is thin and soft, and also has high bulk and tearing strength, low tensile index and burst index. If you are interested in sourcing bamboo pulp making machinery and equipment from China, please feel free to contact us for details.

What is bamboo pulp

The bamboo pulp is one kind of paper pulp like wood pulp, straw pulp or reed pulp. The bamboo pulp is usually made from moso bamboo, phyllostachys pubescens and sinocalamus affinis by sulfate digestion process or soda process. The unbleached bamboo paper is generally applied to package paper-making.

Bamboo pulp can be made into bamboo paper. Bamboo paper is strong and it has wide applications. The bleached bamboo paper is used to manufacture offset paper,typing paper and high-grade culture paper. The unbleached bamboo paper is generally applied to package papermaking. Besides, bamboo pulp and wood pulp can be mixed and used to make cable paper, insulation paper, and cement bag paper.

Bamboo pulp is a viscous solution of bamboo fibers, water, and chemicals used to produce paper and fabrics. Bamboo is a woody, perennial plant belonging to the grass family, which features fibers similar to softwoods in terms of length and strength. The fibers also possess strong anti-bacterial qualities which greatly enhance the properties of items manufactured from bamboo pulp. The pulp is produced in much the same way as wood pulps, with several processes pulping both hard and soft wood varieties in tandem with bamboo. The process involves reducing finely-chipped bamboo to a pulp by“cooking”the chips under pressure in a water and chemical solution in a pressure vessel.

Bamboo is a fast-growing, evergreen plant belonging to the botanical family of grasses. It has long been used as a construction material and as a source of implements, weapons, and ornaments in several global regions, particularly in Asia. In these regions, bamboo pulp has also been used to make high-grade papers for many years. Recent green trends have, however, seen significant amounts of attention paid to the many uses of the plant in other world regions. The fact that many bamboo species grow up to 3.3 feet (1 meter) per day along with several noteworthy physical properties make bamboo an extremely attractive and highly sustainable source of many end products, including bamboo pulp for the manufacture of textiles and paper.

In terms of length and strength, the fibers of bamboo plants are similar to those of softwoods, such as pine and fir, traditionally used to produce the wood pulps destined for paper manufacture. In fact, bamboo is often pulped in tandem with both soft and hard wood varieties due to these similarities. The bamboo fibers also possess anti-bacterial qualities that prevent the formation and spread of bacteria and mildew in fabrics and paper produced from bamboo pulp. In addition, bamboo fibers contain high concentrations of cellulose resulting in strong, robust end products.

The manufacture of bamboo pulp involves chipping the bamboo stems to form a fine aggregate. The chips are then “cooked,” or heated under pressure, in a vessel known as a digester in a solution of water and chemicals. This process breaks the fibers down into a viscous pulp which, when completely digested, is subjected to several clarification stages to remove the chemicals and suspended impurities. The pulp is then dried by drawing residual water from the pulp by means of a vacuum pump and allowing the resultant semi-moist mass to either dry in a batch oven or naturally in the open air. At this point, the dry pulp is compacted into sheets or bales in readiness for distribution.
