First, there is the design and prototyping stage. According to the needs and requirements of the automaker, the automotive interior designer uses computer-aided design software to create three-dimensional models and quickly produces prototypes through 3D printing technology to test and evaluate the feasibility and effectiveness of the design.
Secondly, it enters the material selection and procurement stage. According to the design plan, the manufacturer will select suitable materials to make automotive interior parts, which may include plastics, leather, fabrics, wood, and carbon fiber. The manufacturer will work with suppliers to ensure that the quality and performance of the purchased materials meet the requirements.
Next, it is the mold manufacturing stage. According to the design drawings, the mold manufacturer begins to manufacture molds for automotive interior parts, which are usually made of metal materials such as aluminum alloy or steel. During the mold manufacturing process, tools and equipment such as CNC machine tools are used to gradually process and form the mold, and inspection and testing are carried out to ensure its quality and accuracy.
Then, it enters the injection molding or compression molding stage. For plastic and some composite automotive interior parts, the manufacturer uses an injection molding machine to inject the molten material into the mold, and the molded automotive interior parts are obtained after cooling. For carbon fiber automotive interior parts, molding, vacuum infusion and other processes may be used for molding.
Then, there is the finishing and assembly stage. The molded automotive interior parts may need to be trimmed and surface treated, such as stitching, lamination, painting, grinding and polishing, to improve their surface quality and gloss. Finally, the automotive interior parts will be assembled with other automotive parts to complete the production of the entire car.
In addition, in the manufacturing process of automotive interior parts, some special manufacturing processes may also be involved, such as slush molding, PU spraying, in-mold transfer and low-pressure injection molding, etc. These processes can be selected according to specific needs. Appropriate automotive interior parts manufacturing process.
Finally, quality control and testing are also an indispensable part of the manufacturing process of automotive interior parts to ensure that the quality and performance of the final product meet the standards.
