Injection Molding Knowledge Center

As a professional vertical injection molding machine manufacturer (MINHUI), we are often asked a core question by our clients: Should I use TPR or silicone for my product? These two materials, which appear and feel similar, have very different requirements for injection molding equipment. Understanding their differences is the critical first step to ensuring the […]

Nowadays, there are many manufacturers of injection molding machines, and various specifications, models, quality, and grades of injection molding machines can meet the needs of different manufacturers, so we do not know where to start when selecting injection molding machines models. How to quickly select the injection molding machine, the following is to introduce the

Generally speaking, enterprises or department managers and related technical personnel who have been engaged in the plastic products industry for many years are capable of making their judgment and choosing the suitable injection molding machine for purchase because they have experience in using injection molding machines. However, many enterprises or department managers may not know

The application of plastic parts is becoming more and more widespread, from simple tableware and kitchenware to complex mechanical parts, electronic products shells, etc. are used to plastic parts, but for electronic products shells and other plastic parts with high precision requirements, in the injection molding manufacturing from the beginning of the mold manufacturing should

Different material shrinkage will produce problems, such as product sink, deformation warpage, size abnormality, batch front, etc. Therefore, mastering the skill of using good pressure-holding can solve most of the lousy injection molding. The material is in high temperature and high pressure at high speed from liquid to solid. The material is composed of molecules

Liquid silicone products have high transparency and no odor. The products have glue injection edges, no obvious mould pattern and hair edge defects. The appearance is more exquisite. Solid silicone products have low transparency, the smell of curing agents or other curing agents, the products are not injected with glue, the mould is closed at

There are numerous ways to classify automotive plastic molds according to the different plastic corridor molding, and processing styles can be divided into the following orders.    -Injection mold The molding process is characterized by placing the plastic material in the heated barrel of the injection machine. The plastic is heated and molten, pushed by

What is undercut? I believe that those engaged in the injection molding industry know, so I will not repeat it. The undercut is not a complex problem in injection molding, but it is common in almost all injection molding factories. The reason for this is that there are too many types of burrs, and the

I believe that the injection molding industry, injection molding technician positions above, have encountered the production process of injection molding products, due to water reasons, the production of products due to deformation caused by the lousy batch situation: deformation, visual inspection is challenging to find, only when assembled with, only to find that the assembly
