Reasons and Solutions for Shrinkage Rate of Injection Mold

Shrinkage rate of injection mold is always an important part in the development of injection mold. This ring has a tremendous impact on the size of the plastic. After the structure of the die is determined, all parts of the die can be designed in detail, that is, the size of the template and parts, the size of the cavity and core, etc. At this time, the main design parameters such as shrinkage of materials will be involved. Therefore, […]

Why Plastic Material need baked Before Injection Moulding?

In the process of injection moulding, the moisture content of material should be within a relatively low range to ensure the normal injection moulding and the normal physical properties of product materials. The water content of injection material is too high. First, there will be bad appearance of silver wire on the surface. Secondly, water vapor in the material will cause bubble holes in the product, which will affect the strength. Thirdly, if the moisture content is high, the […]

Why It Is Expensive to Customize A Set of Plastic Injection Moulds?

Plastic injection moulding is an efficient and mass production method, which can realize one-time moulding of plastic products with complex shapes. In the mould industry, in order to produce injection moulds with high precision, high quality and complex surface, we must use advanced computer aided design and manufacturing software to compile reasonable processing procedures, which is the necessary process to ensure the processing quality.

In addition to the above reasons, the reasons for the higher price of injection moulds are […]

How to Do a Good Job of Injection Molding Process?

The process of injection molding mainly includes four stages: filling, holding, cooling and demolding. These four stages directly determine the quality of the product. It is a complete continuous process. Injection parameters

Injection parameters

Injection pressure

Injection pressure is provided by the hydraulic system of the injection system. There are many factors affecting the filling pressure of melt, which can be summarized into three categories: (1) material factors, such as the type and viscosity of plastics; (2) structural factors, such as the […]

Three Types of Plastic moulds, Which One Is More Cost-Effective?

Plastic moulds can be divided into three categories, each of which has its advantages and disadvantages. Which of these three types of plastic moulds is more cost-effective?

(1) Large nozzle mould: Runner and gate are demoulded together with the product on the parting line. The design is the simplest, easy to process, and the cost is low. Therefore, more people use large nozzle system to operate.

(2) Fine nozzle mould: the runner and gate are not on the parting line, generally […]

Three Principles of Mold Material Selection

(1) Mold meets working conditions

Wear resistance

When the billet is plastic denatured in the cavity, it flows and slides along the surface of the cavity, resulting in severe friction between the surface of the cavity and the billet, which leads to the failure of the mold due to wear. So the wear resistance of materials is one of the most basic and important properties of dies.

Hardness is the main factor affecting wear resistance. Generally speaking, the higher the hardness of mold parts, […]

Analysis of Common Failure of Plastic Mould

Plastic mould is for plastic processing and forming. They are made of 45 steel, P20, 718 and other plastic mould steels. The failure analysis of plastic mould can better guide the research and development of mould steel. The failure modes of plastic mould are as follows:

Abrasion and Corrosion of Cavity Surface

1) Plastic melt flows in the cavity with a certain pressure, and solidified plastic parts come out of the mould, which will cause friction and wear on the surface of the […]
