Injection molding is a processing method used in mass production of complex parts. Specific principle refers to: heat melting plastic raw materials by injection molding machine screw into the mold cavity, after cooling and curing, plastic forming products. The plastic mold consists of two parts: moving mold and fixed mold. The moving mold is installed

In the process of mold manufacturing, deformation often occurs, so how to avoid the deformation in mold manufacturing? (1) the thickness of the product shall be as uniform as possible. (2) all parts of the cooling system are designed to make the cavity temperature uniform. (3) the pouring system can make the material flow symmetrical,

Defects in most injection molding products are caused during the plasticizing and injection phases of the injection molding parts, but are sometimes related to design irrationality, including the type of injection port, the number of mold cavities, location and size, the design of the cold and hot runner system, and the structure of the product

Ultrasonic welding in the assembly of plastic parts is commonly used to a process. ABS, PC+ABS, PP, PC, etc. these materials are suitable for ultrasonic welding. Generally used for ultrasonic two parts are required to be the same material. Ultrasonic bonding will be better. If nylon or POM is used to ultrasonic with ABS, this

Product structure is undoubtedly the key factor to determine the price of the mold, the realization of a product function has a variety of different design, different design determines the mold manufacturing method is not the same, determine the price of the mold will be different, some structure only need us to pay attention to

Screw post is also called boss, which is a feature of most products. What key points should we pay attention to when designing the structure? Let’s have a look: The wall thickness of the boss, at the time of structure design, we need to consider the strength of the boss, so as far as possible

How should plastic product appear bubble to do? Our engineer’s answer is that the reason may in the equipment, plastic mold, and may also in the injection process, the following is the reason analysis of the process, hope to help you solve the problem. The back pressure of screw pre-molding is too low and the

In recent years, more and more kinds of plastic products come into our life, at the same time the development of injection molding technology get injection molding products replace other material life and industrial supplies, now almost all things are linked with injection molding parts. So how to distinguish injection plastic material is also a

In modern society, automobile has become an important means of transportation for people to travel. Its quality not only affects people’s travel quality, but also directly affects people’s life and property safety. Generally, the service life of automobile mould is 600000 to 800000 times. In the process of automobile mold design and production, we should
