Background
The IML process is also called an intramembrane insert injection molding process, and has the remarkable characteristics that: the surface is a hardened transparent film, the middle is a printing pattern layer, the back is a plastic layer, and the printing ink is sandwiched between the two layers, so that the product can prevent the surface from being scratched and is resistant to friction, and can keep bright color for a long time and is difficult to fade. The flow of the IML process comprises the following steps: cutting, plane printing, ink drying and fixing, sticking a protective film, punching a positioning hole, thermoforming (high-pressure or copper mold), cutting the peripheral shape, and cutting and injecting the material.
The existing IML process product is usually processed into a complete 3D product according to the flow. However, after printing a specific functional pattern on a film, the film needs to be baked at a high temperature during 3D molding to soften the film sufficiently, and then the film is molded by clamping. When the ink layer of the printing film is baked at high temperature, orange peel lines are generated due to softening of the ink layer. When the mold is used for injection molding, the film is coated on the surface layer of the plastic part, and obvious orange peel lines can be seen on the surface of the product, so that the appearance of the product is influenced.
