In the automotive sector, products have complex structures such as battery seats, gas pumping covers, and multi-valve housings. Many of these injection molding car parts products require consideration for the insertion of metal parts. Some are produced by co-injection molding on the injection molding machine, we provide automotive plastic injection molding of high-end vertical injection machine for this kind of products, while others are formed through finished hot pressing. Take hot-pressed metal parts as an example: we've optimized our processes using heat-conductive oils and PTFE coatings to enhance efficiency and product quality during thermal pressing operations. These innovations not only improve manufacturing throughput but also ensure that automotive components meet stringent performance standards and durability requirements.
