Description
Technical Field
[0001] The utility model relates to the technical field of coloring equipment, in particular to a coloring device for automobile interior injection moldings. Background Art
[0002] Automotive injection molding refers to various automotive-related plastic parts manufactured by injection molding technology. They are usually made of a variety of high-strength and durable plastic materials, such as polypropylene (PP), polystyrene (PS) and polycarbonate (PC). In automobile manufacturing, injection molding is mainly used for various precision or large parts such as dashboards, seat support frames, spare tire seats, bumpers, air intake grilles, headlights, etc. in the interior of the car. These injection moldings play a role in structural support and ensuring the safety and comfort of automobile driving. Compared with other materials such as steel and aluminum, injection moldings have higher plasticity, durability, lower production costs and shorter production cycles, and higher overall manufacturing efficiency. In automobile manufacturing, automotive interior injection moldings need to be colored to play a decorative and protective role. However, most of the existing coloring raw materials are not fully mixed before use, and their components may not be evenly distributed on the surface of the injection molding, resulting in reduced adhesion, which may cause problems such as easy peeling, discoloration or bubbling of the paint. Due to uneven distribution of the paint or poor adhesion, defects or quality problems may occur on the surface of the injection molding. These unqualified injection molded parts may need to be reprocessed or scrapped, which increases production costs and scrap rates. Therefore, a better coloring device for automobile interior injection molded parts is urgently needed. Utility Model Content
