Test the properties of injection mold We should test the various properties of injection mold under the normal operation of the injection molding machine and mold. Then measure the size of the final molded plastic part. And deterine the current state of the mold with this information. Besides, we can also fina the

Why Adding Glass Fiber to the Plastic Parts ? Are you still worrying about the "floating fiber" on the surface? Plastic parts have many shortcomings in the using process. To make plastic parts more suitable for other fields (replace steel with plastic ) and change the properties of resin like wear resistance, heat resistance, strength, fire resistance, etc., it’s a

The operating procedures of the injection molding machine are as follows: (1) The operator must be familiar with and understand the function of each switch button on the equipment operation panel. And operate in strict accordance with the operating rules and attentions. (2) Before the machine heats up and starts production, open the cooling

When filling the mold at low speed, the flow rate and the product size is relatively stable with small fluctuation. What’s more, the internal stress of the product is low, and the internal and external stress tends to be consistent. For example, a polycarbonate part is immersed in carbon tetrachloride, the product using the high-speed injection molding has a

As the most important production tool of the injection molding factory, the injection mold determines the shape, specification, size, and appearance finish of the product. The material of the hardware mold is steel, which is generally composed of a front mold and rear mold. Due to the specificity, precision, vulnerability and other characteristics of

There are many differences between the processing of LSR and traditional thermoplastic rubber, which increase the processing difficulty. LSR is quite different from traditional thermoplastic material processing in terms of shrinkage, demoulding, mold material, cold runner system, temperature control, etc. That  makes the processing of LSR more difficult than that of ordinary thermoplastic rubber. The waterproof

Mold management can be roughly divided into 3 different parts. That is mold development, mold use and mold maintenance. Therefore, for the effective mold management, companies or factories can start from the process to improve the problems of management. 1. The development of mold First of all, in terms of mold development, companies need to

Over injection molding, like co-injection molding, bicolor injection molding and sandwich injection molding, belongs to multi-material injection molding technology. The basic idea of multi-material injection molding is to combine two or more materials with different characteristics to increase product value. The first injected material is called the base material or substrate. And the second type of injected material is called

1. The matrix resin itself The transparency of the matrix resin itself has a great influence on that of PP products. To improve the transparency of PP, we can add a small amount of polyacrylate resin with good compatibility and excellent transparency. 2. Nucleating agent Significantly increase the crystallization velocity, the crystallization rate and crystal

The injection speed is a key parameter of injection molding for its close relationship with product quality. Determine the beginning, middle, and end of the injection speed segment. Moreover, realize a smooth transition from one set point to another. These can ensure a stable melt surface speed producing the desired molecule and the smallest
