Precision molds possess unique characteristics-such as high dimensional accuracy, strict repeatability, and superior material quality-and rely on precision injection molding machines and specialized molding processes. The dimensional accuracy of precision molds is exceptionally high, with tolerances controlled within extremely narrow ranges to ensure precise dimensional boundaries. Furthermore, precision molds demand rigorous dimensional stability, maintaining a high degree of consistency over periods spanning days, months, and even years.
Regarding the selection of mold materials, precision molds also adhere to elevated standards. The materials utilized must not only exhibit excellent rigidity, but the dimensional accuracy of the mold cavities, their surface finish, and the positioning precision between mold plates must all meet exacting standards.
