Compared with the traditional injection molding process, RIM polyurethane materials and processes have the advantages of low energy consumption, light weight, simple process, and low mold and manufacturing costs. Modern automobiles are designed to meet higher comfort requirements, and their functions are becoming more and more complex. More parts must be accommodated in the space, so the space left for the wiring harness is narrower and irregular. The constraints of traditional injection molds in this regard are becoming more and more obvious, while the mold design of polyurethane is more flexible.
Reinforced Reaction Injection Molding (RRIM) is a new type of reaction injection molding technology, which prepares products with better mechanical properties by placing fibrous fillers such as glass fibers in a preheated mold.
Using existing polyurethane equipment and materials to carry out research on polyurethane technology can optimize the manufacturing process of materials and improve the performance of materials. In the future, the technology should be introduced more deeply to the manufacture of automobile wire harness guide grooves. Finally, the enterprise can achieve the goal of reducing costs and improving market competitiveness.
