How to improve injection mould quality?

YIGE Mold, as the top professional mould making manufacturer in China, we know how to improve the mould quality.

1. Mould steel

Steel is the decisive factor of mold quality, and choosing reasonable steel is the top priority. The criteria for selecting steel are:

①Requirements for injection molding materials—different plastics should use different steels, such as high polishing requirements, corrosion resistance requirements, etc.;

②Price—the steel can be used, not the more expensive the better; considering the cost factor of the mold, the mold steel should choose the material corresponding to the mold life to avoid unnecessary waste;

③Heat treatment. The surface treatment of the mold is also very important. Nitriding can enhance the surface hardness of steel and effectively extend the life of the mold; electroplating can effectively modify the mold steel, and for some plastic parts that require high brightness and corrosion resistance, electroplating can be used to enhance and improve the performance of the steel.

2. Structural design

The mature mold structure not only considers the product material properties-shrinkage rate, molding temperature, elastic tensile deformation coefficient, etc. but also considers the cooling water circuit, the speed of mold opening and closing, etc. A reasonable mold structure can effectively extend the life of the mold and ensure smooth production of the mold. Improve efficiency and reduce costs.
