The color of the injection molded product is colorful and highly ornamental. The raw materials for processing are transparent and translucent polyethylene and polypropylene. The reason for the rich color is that it needs to be colored. What are the reasons for the uneven color of injection molding Poor diffusion of the colorant, which often […]
The fluidity of thermoplastics can usually be analyzed by a series of indicators, such as molecular weight, melt index, Archimedes spiral flow length, apparent viscosity and flow ratio (processing length/plastic part wall thickness). Small molecular weight, wide molecular weight distribution, poor molecular structure regularity, high melt index, long spiral flow length, low apparent viscosity, high […]
Molding cable ties is a competitive, high-volume business that, to be successful, demands fast cycles, robust processes, and nearly perfect parts. You look at a cable tie and it looks like a relatively simple product, but it’s an exercise in contradiction in reality, because the cable tie product stretches the limits of injection molding. The […]
The full name of INS is INSert-Mould-Decoration, which refers to putting a blister-shaped film into an injection mold for injection molding. The INS process is a new process derived from the IML process. As countries have higher and higher requirements for ecological and environmental protection, the INS process has been widely used in modern advanced […]
The main reasons and solutions for the uneven color of injection molded products are as follows: (1) The colorant is poorly diffused, which tends to cause a pattern near the gate. (2) The plastic or colorant has poor thermal stability. To stabilize the color tone of the part, it is necessary to strictly fix the […]
The quality of the mold is directly related to the quality of the product, production efficiency and cost. I think everyone will not have any objection. The quality of the mold needs to be tested by the mold to find the problem and solve the problem. Therefore, it is very important for the mold company […]

After more than half a century of development, China’s mold industry has had a big promotion and is very agile. In 2018, the sales expenditure of enterprises above the national mold industry was 213.616 billion yuan, a decrease of 19.8% compared with the previous year. However, compared with 2010, there is still a large promotion. […]
Storage and transportation have always been the main factors restricting the development of the fresh market. With the advent of fresh plastic folding turnover boxes and cold chain transportation, the development of fresh transportation has been greatly promoted. Most of the plastic folding turnover boxes are made of PP material, which is non-toxic and non-polluting, […]
The wall thickness of the plastic folding turnover box mainly depends on the box mould accuracy and precision. The wall thickness of the side wall of the folding turnover box is too thin, which may cause a decrease in compressive strength and impact strength. We can test the quality of the plastic turnover box by […]
