1. PU, PVC appearance quality inspection: under 40W fluorescent lamp illumination, the distance from the tested material 40 ~ 50cm, the color and pattern must be consistent with the standard sample. There should be no obvious scratches, breakages, exposed bottoms, impurities or delaminations.

2. Dimensional inspection of PU and PVC: Use a thickness gauge with an accuracy of 0.05MM to measure. For materials with a nominal thickness of 0.5 ~ 1.0MM, the deviation cannot exceed ± 0.10MM; for materials with a nominal thickness of 1.0 ~ 1.5MM, The deviation cannot exceed ± 0.15MM; for materials with a nominal thickness of 1.5 ~ 2.0MM, the deviation cannot exceed ± 0.20MM. Measure the width with a steel tape with an accuracy of 1MM, and the deviation of the width dimension should be ± 3.0MM.

Performance inspection of PU and PVC:

1. Elasticity: Bend the material sample to 90 degrees, and its rebound degree should be consistent with the standard sample.

2.Stretchability: A 10Kg tensile force is applied to the material sample and the standard sample at the same time. After the external force is removed, the expansion and contraction of the two materials must be the same. .

3. Anti-aging property: Take PU, PVC material samples and standard material samples frozen at -10 ± 3 degrees Celsius for 2 hours, and bake at 45 ± 3 degrees Celsius for 2 hours. determination.

1. Preparation before inspection

1) Confirm the computer and auxiliary equipment used for testing (the USB interface is plugged in normally, and the extended HUB works normally)

2) Confirm computer test software (antivirus, read / write speed, chip check software, etc.)

5) File check in U disk.

6) Check the data transmission after the computer and the U disk are successfully connected

7) Use your computer’s antivirus software to check for viruses.

3. Special inspection items:

Inspection Standards:

1. Capacity: On the one hand, the capacity of the insulated container can hold enough items. On the other hand, it is directly related to the holding temperature, that is, the same caliber, the larger the capacity, the higher the holding temperature. Therefore, the positive and negative deviations of the capacity of the insulated container cannot be too large.

2. Hot water leakage: This project involves the use of safety and affects the beauty of the use environment. When the problem of this project is serious, as long as the thermos bottle filled with water is lifted, hot water will leak between the bladder and the shell, and the user will be burned if the amount is large. Even if the amount is small, it will leak water on the table and the floor, affecting the environment Beautiful.

3. Impact resistance: This item is related to the service life of the product. During the use of the product, bumps are unavoidable. If the materials used in the product accessories have poor shock resistance or the accuracy of the accessories is insufficient, there will be a gap between the bottle liner and the shell. Shaking and bumps in use may cause stone damage. Cotton pad displacement and cracks in the small tail affect the product’s thermal insulation performance. In severe cases, it can cause cracks and even breakage of the bottle liner.

4. Identification: National standards stipulate that the product name, capacity, caliber, manufacturer’s name and address, the standard number used, the method of use, and the precautions in use must be clearly marked.

Precautions:

1. Appearance. The beautiful shape of the insulation cup will be attractive, of course, it depends on the technology of the insulation cup, the details of the workmanship, whether the interface will be delicate, whether the edge of the insulation cup will be smooth and flat. An exquisitely crafted insulation cup represents the importance that manufacturers place on product quality.

2. Material. Stainless steel insulation cups must be food-grade 304 stainless steel. It is best to use 304 steel for the inner tank to ensure that the amount of heavy metals dissolved in the insulation cup used for water does not exceed the standard, including lead. The amount of heavy metals dissolved in the cheap 201 or 202 stainless steel cup is more than 100 times that of 304 steel. The outer shell is irrelevant. Both inside and outside are made of 304 steel. The inner cover is plastic. It is easy to identify. It smells odorless. The best is the PC material. The PC material is boiled in boiling water and has no taste and will not deform.

3. Look at the inner cover. The inner lid of a good insulated cup is normally made of PC material, it smells no taste, and the plastic has good brightness and flatness. The lid should be easy to clear, and there should be no sanitary blind spots that cannot be cleaned, so that it can be cleaned and used.

4. Twist the lid. A good quality thermos cup should be quite smooth and smooth when twisting the lid, with a uniform 360-degree rotation. The thermos cup is used to drink water. It must be opened and tightened several times a day. If the cap is twisted at the beginning, it will be uneven in weight or make a harsh sound. Such a thermos cup will not be used for a long time.

Total quality management. Since the 1950s, with the rapid development of productivity and the rapid development of science and technology, people focus on the quality of products from the general performance of products to pay attention to the durability, reliability, safety, maintainability and economy of products. A systematic approach to quality problems is required in production technology and enterprise management. There are also new developments in management theory that emphasize the human factor and rely on the efforts of all employees to ensure quality. In addition, with the rise of the “consumer protection” movement, market competition among enterprises is becoming increasingly fierce. In this case, the American A.V. feigenbaum proposed the concept of total quality management in the early 1960s. He proposed that TQM is “an effective system for producing and providing services at the most economical level and taking into account the full satisfaction of customer requirements, and for integrating the activities of all departments in the development, maintenance and improvement of quality”.

Strengthen people’s concept of quality

The main purpose of product quality management is to better ensure the quality of products, so as to meet the quality requirements of more customers, laws and regulations, such as practicality, safety and reliability. Product quality management is through the establishment of quality objectives and plans, and in order to achieve this goal and plans to carry out a series of quality planning, quality control, quality assurance and quality improvement activities to complete.

The main factor restricting the improvement of product quality is not only the technical level, but also the lack of a strong quality concept. Improving the quality of products involves the whole process of product construction. And what needs to be addressed urgently is the ideology of the product manufacturer, that is, people’s concept of quality. Improving people’s quality concept is the main content of product management. The quality concept shows the staff’s understanding of quality and attitude towards quality problems, which also affects the staff’s quality attitude and work behavior. Lack of quality concept will make employees have a negative quality attitude and inappropriate quality behavior, more serious will also restrict the improvement of enterprise product quality and quality work. For many enterprises in China, the requirements for product quality are not perfect, but sloppy, especially when there is a conflict between product quality and actual interests, they generally put economic interests in the first place, which seriously restricts the improvement of product quality in China.

To improve the quality concept of enterprise employees, we should stick to it and start from various aspects. From senior leaders to general managers to front-line staff, the whole enterprise should set up the concept of “product quality is the life of the enterprise”, and integrate the improvement of product quality into all aspects of production. Through the cultivation and education of quality knowledge, enterprises make people realize the importance of quality, pay attention to the relationship between people and product quality, let employees master the basic theory and working methods of quality management, and integrate them into the actual work, and can also sign the “quality responsibility letter” for quality control. If the idea of “quality first” is formed in an enterprise, these good styles will be formed into an important part of the enterprise culture — quality culture after a long time of accumulation, thus ensuring the quality of products will become a matter of course.

The whole process of product production is a complicated work system, among which quality management is the most important management factor. We generally think that product quality only refers to the quality of product manufacturing, not too much attention to the quality of product development and product use. This kind of understanding is to generalize, did not explain the overall meaning of product quality. In fact, from the perspective of product circulation, product quality is mainly reflected in the following stages. To establish a product quality management system, it is necessary to establish it in a piecewise manner.

Establish a quality management system for product development

From a theoretical point of view, product quality is previously constructed, not last detected. The quality of product development has a direct impact on the actual quality of the product. If you think about it, when you’re developing a product, it’s very likely that you’re going to produce something that doesn’t meet the standards or that doesn’t follow the rules, and you’re not going to produce a high-quality product. Therefore, product development quality plays a decisive role in the quality of the product itself. Enterprises should start from product development and carry out quality management.

Create quality management for product manufacturing

Product construction is the production process of the enterprise. The quality of products in the production process has an important impact on the quality of products. Product quality management is a frequently discussed topic. In the process of product production, it is inevitable to be affected by various factors, such as people, methods, machines, materials, environment and so on. This requires the management personnel and the operation personnel to take effective measures to correct and deal with when working.

When testing the quality of product production process: high yield, excellent, low consumption. In order to better achieve this goal, it is necessary to meet from the human, material and financial aspects, which is the prerequisite for product production. What’s more, the factors of production, such as people, money, materials and information, should maintain the best state in the actual production process, striving to make the best use of talents and materials to ensure the smoothness and clarity of finance and information. The process of product manufacturing is the main objective of quality management, so that the products produced meet the product requirements at the time of development. Pass the inspection to accord with the standard is excellent product, do not accord with is inferior product and waste.

Unless you are living under a rock, you may have heard about the coronavirus originated in Wuhan, China. The Hubei province, and much of China, is in complete lockdown with many businesses closed, and people staying home as the government extended Chinese New Year for a few days until the epidemic is under control.

This should obviously have an economic impact, at least in the short term, for the next few weeks or months since people are asked to stay home, and a lot of goods consumed is manufactured in China. And indeed, some companies are announcing delays due to the virus.

It’s difficult to find updates of delivery time from companies actually based in China, potentially because they need to check with their sub-suppliers to check whether they are affected by the virus or not. But I’d assume if you have purchased products from Aliexpress, GearBest, GeekBuying, and the likes, and if the parcel has not left China yet, you won’t get it anytime soon unless there are stock at the suppliers’ warehosue. By the way, the virus needs a carrier (e.g. living creature) to stay alive, so there’s no risk to get infected with the coronavirus from a package since it takes several weeks to arrive at its destination.

So far by Feb 1st,2020, Chinese government has officially extended the Lunar Spring Festival to Feb 10th,2020. And only some important retailed shops, foods market, logitic company, mask factories etc are allowed to run first. As I witness, some Chinese companies will have their employee work at home for the week of Feb 3 to Feb 7th, so I believe they will update you the situations when you talk to them if you buy from them.

So beside the human toll, there will be an economic impact, but only time will tell just how much this impact will be.

1. Control sample or confirm sample. See if the color and model match the sample;

2. The surface of the button must be free of nicks, cracks, unevenness and obvious scratches;
