Abstract

The invention provides an in-mold decoration injection process which comprises a step of preparing a mold and a film, a step of drying a net making plate in the sun and preheating a sheet, a step of printing a pattern, a step of curing printing ink, a step of punching for positioning, a step of punching, a step of hotly pressing for forming, a step of injecting for forming, a step of packaging a semi-finished product, a step of checking and a step of warehousing a finished product. The finished product is scratch-resistant, strong in corrosiveness, long in service life, good in body sensation, attractive, light, firm and safe, can provide more choices for final users, and is widely applied to various products such as household appliance products, computers and peripherals, mobile communication terminal products, and in the technical field of car industry and the like.

Description

technical field [0001] The invention relates to the technical field of IMD / IML, in particular to an injection molding process for in-mold decoration. technical background [0002] The traditional plastic processing technology has gradually been unable to meet the needs of the new era. Light, thin, short consumer electronics and environmental protection awareness are on the rise. IMD technology came into being on this basis. Due to the many advantages of (IMD), it is suitable for plastic products of 3C, home appliances, LOGO nameplates and auto parts, especially the currently popular mobile phone casings and various instrument panels. For this reason, many materials in the world, such as Bayer in Germany, GE in the United States, Japan and South Korea, are investing a lot of manpower and financial resources in the research and development of new materials suitable for this process, and a large number of functional films and ink materials emerge every year. [0003] The Chine...
