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

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

Cracks, including filament cracks, microcrack, whitening, cracking on the surface of parts, as well as cracks and fracture time due to component adhesion, flow path adhesion or traumatic damage. The main reasons are as follows: Processing: (1) Excessive processing pressure, too fast, the more filling materials, injection, holding pressure for too long, will cause excessive

All kinds of tools used in our daily production and life, from the body shell to the head screw, button and the shell of all kinds of household appliances, have an inseparable relationship with the mold. The shape of the mold determines the shape of these products. The processing accuracy and quality of the mould

When customers ask to quote a injection tooling cost for their products, they often do not understand the price is how to evaluate, and want to know why the tooling cost for big product is higher than small one. Now let’s see what will determine the price of injection tooling ? JasonMould based on years
