Scheduled online at and also presented here below, is some excellent valuable guidance and advice on the key requirements to look out for when purchasing Taizhou Booling plastic moulds.

Consideration 1 – High corrosion resistance Many resins and additives have a corrosive effect on the cavity surface. This corrosion causes the metal on the cavity surface to dissolve and fall off, the surface condition is deteriorated, and the quality of the plastic parts is deteriorated. Therefore, it is best to use corrosion-resistant steel or chrome-plated and samarium-nickel treatment on the cavity surface.

Consideration 2 – Good abrasion resistance The gloss and accuracy of the surface of plastic and plastic parts are directly related to the abrasion resistance of the surface of the cavity of the plastic mold, especially when some plastics are added with glass fiber, inorganic fillers and certain pigments. It moves rapidly in the flow channel and mold cavity together with the plastic melt, and the friction on the surface of the cavity is very large. If the material is not abrasion-resistant, it will wear quickly, which will endanger the quality of the plastic part.

Consideration 3 – Excellent dimensional stability During plastic molding, the temperature of the cavity of the plastic mold must reach above 300 ° C. For this reason, it is best to use a tool steel (heat-treated steel) that has been appropriately tempered. Otherwise, the microstructure of the material will be changed, which will cause changes in the dimensions of the plastic mould.

Consideration 4 – Easy to process mould parts are mostly made of metal materials, and some structural shapes are still very complicated. In order to shorten the production cycle and improve power, mold materials are required to be easily processed into the shape and accuracy required by drawings.

Consideration 5 – Good polishing performance Plastic and plastic parts generally require excellent gloss and surface conditions, so the roughness of the cavity surface is very small. In this way, it is necessary to perform surface processing on the cavity surface, such as polishing and grinding. Therefore, the selected steel should not contain rough impurities and pores.

Consideration 6 – Little influence by heat treatment In order to improve the hardness and wear resistance, plastic molds are generally heat treated, but this treatment should make the size change small. Therefore, it is best to use pre-hardened steel that can be machined.
