How to identify the advantages and disadvantages of injection molds

Now in China, injection mold factories are everywhere, but how do we identify the advantages and disadvantages of injection molds? Today, the editor of Hetai Plastic Mould analyzes and talks with you.

What is an injection mold

The injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain shapes and complex parts. Specifically, the plastic melted by heat is injected into the mold cavity by a high-pressure injection molding machine, and after cooling and solidification, a molded product is obtained.

The application of mold

Mould is the basic process equipment for industrial production. As the basic industry of the national economy, the mold involves various industries such as machinery, automobile, light power, electronics, chemical industry, metallurgy, building materials and so on. It has a wide range of applications and has begun to gradually penetrate into all industries and us. All aspects of life. We cannot live without molds in our lives. Computers, telephones, fax machines, keyboards, cups, etc. are all manufactured through strict injection molding processes. Therefore, the selection of high-quality injection mold manufacturers is extremely important in our daily life.

The method of identifying high-quality molds

  • 1. The polishing performance of the mold cavity surface must be excellent, so that the surface roughness value is minimized. Injection mold processing manufacturers should have a good polishing workshop and equipment to ensure the excellent polishing performance of the mold
  • 2. The mold must have good thermal stability performance. After the mold is quenched, the size of the mold should ensure that the front and back values ​​are basically unchanged. This is very strict for the process requirements of the injection mold processing manufacturers.
  • 3. The mold surface must have sufficient hardness and excellent wear resistance. This requires that injection mold manufacturers have certain requirements in the selection of injection mold materials in the early stage.
