MOLD FOR INJECTION MOLDING

摘要

A mold for injection molding is provided to form an elegant pattern in a surface of an injection-molded product without needing an additional process after injection molding by including a contact surface and a non-contact surface. A mold(100) for injection molding comprises a contact surface(101) and a non-contact surface(102). The contact surface includes a high flat contact surface(ss) and an irregular micro-embossed contact surface(s) having larger calculated average coarseness than the calculated average coarseness of the high flat contact surface. A pattern is formed in the contact surface by difference of the calculated average coarseness between the high flat contact surface and the irregular micro-embossed contact surface.
