What is the impact of surface treatment on plastic injection mold

The surface treatment of plastic injection molds has an important impact on their performance, service life and production efficiency. Reasonable surface treatment can improve the surface quality, wear resistance and corrosion resistance of the mold, thereby ensuring the molding quality and production efficiency of plastic products.

Improve surface quality

Surface treatment can effectively improve the surface quality of the mold, making it smooth and flat, and reducing flaws and defects. In the plastic injection molding process, the quality of the mold surface directly affects the surface finish and appearance quality of the molded product. Through surface treatment, the roughness and oxides on the mold surface can be eliminated, the friction and wear between the mold and the molded parts can be reduced, and the appearance quality and consistency of the molded products can be ensured.

Extend mold life

Surface treatment can improve the wear resistance and corrosion resistance of the mold and extend its service life. During the plastic injection molding production process, the mold surface is often subjected to high temperature, high pressure and chemical corrosion, which can easily lead to surface wear and corrosion. Through surface treatment, a hard and wear-resistant surface coating or surface treatment layer can be formed to effectively protect the mold surface, extend its service life, and reduce maintenance costs.

Improve release performance

Good surface treatment can improve the demoulding performance of the mold and reduce the occurrence of product residue and mold jamming. In the plastic injection molding process, the roughness and lubricity of the mold surface directly affect the demoulding effect of the product. Through surface treatment, the surface of the mold can be made smoother and more uniform, the friction between the mold and the product can be reduced, the demoulding performance of the product can be improved, and product residues and scrap rates can be reduced.

Improve molding accuracy

Surface treatment can also improve the molding accuracy and dimensional stability of the mold, and improve the processing accuracy and consistency of the product. In the plastic injection molding process, the quality and accuracy of the mold surface directly affect the dimensional accuracy and consistency of the molded product. Through surface treatment, the surface finish and processing accuracy of the mold can be improved, the dimensional deviation and deformation of the molded product can be reduced, and the molding accuracy and quality stability of the product can be improved.
