In-Mold Decoration (IMD) is a plastic product surface decoration process. It helps people to get the desired shape and size of the part by molding the material, and also can give the external surface of the part certain physical, chemical, electrical and tactile decorative engineering properties, etc. It is increasingly applied to different products in various industries by designers. For example: ① It can give injection molded parts higher abrasion resistance, scratch resistance, corrosion resistance, antibacterial, water resistance, rust resistance, anti-magnetic, anti-static, anti-radio interference, anti-ultraviolet radiation, glossiness, smoothness, color vividness, etc.; ② It can improve the heat resistance, fire resistance, flame resistance, insulation, electrical conductivity, etc. of the extruded parts; ③ It can improve the plastic parts (plates, tubes) hardness resistance, shock resistance, luminous, reflectivity, etc.; ④ It can improve the ...
