Injection Molding Knowledge Center

A vertical injection molding machine or multi-color vertical injection molding machine is a model of the vertical injection molding machine. Its main use lies in injection molding to plastic products that need multi-color injection molding, such as common toothbrush handles, cell phone cases, toy accessories, etc. 1. Turntable After the second molding opens the mold, […]

What Is LSR?   Liquid Silicone Rubber (LSR) is a two-component system made of silicone. It is a versatile polymer that can be molded or cast into silicone rubber sheets. Its name makes this polymer very different from gum-based silicones, which are high in consistency. Liquid silicone rubber has low compression set, which means that

Products are usually injection molded in two ways, rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding method and die-casting method. Injection molding machine (referred to as injection molding machine or injection molding machine) is the main molding equipment that makes thermoplastic or thermosetting materials into various plastic

Opening molds for rubber molding, especially liquid silicone (LSR) injection, can be very challenging. Many people believe that rubber molding is less technically challenging. The opposite is true. In many cases, LSR molds require more precision and expertise than thermoplastic molds. Liquid Silicone Products Preventing flying edges Both thermoplastic and LSR molds have very complex

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
