As an important tool for the production of injection molded parts, precision injection mold tooling have many factors that affect the accuracy and quality of injection molded parts. The following are our summary of which factors on precision injection mold tooling have an important impact on the accuracy of injection molded parts.
The accuracy of the injection mold mainly depends on the accuracy of the mold cavity size, the accuracy of the cavity position, or whether the accuracy of the parting surface meets the design requirements. The dimensional tolerance of ordinary precision injection mold tooling should be controlled within 1/3 of the product dimensional tolerance.
In the mold structure design, the number of cavities should not be too many, and the bottom plate, support plate, and cavity walls should be as thick as possible to avoid elastic deformation of the product under high temperature and high pressure.
Precision injection mold tooling should use as few cavities as possible, short runners, and high finish, which is beneficial to demolding.
Choose steel with high mechanical strength. The materials for making the cavity and runner must undergo rigorous heat treatment, and the materials should be selected with high hardness, good wear resistance and strong corrosion resistance.
