The RIM process can adapt to parts with complex shapes, and the design freedom of the parts is high. One of the benefits obtained from the lower cavity internal pressure is that the mold can be designed as a three-dimensional parting structure, so that it can cope with more complex product structures. In addition, the characteristics of the three-dimensional parting structure can easily carry out the mold design of the insert structure. Structural Reaction Injection Molding (SRIM-Structural Reaction Injection Molding) can be produced by adding specific reinforcing materials to the liquid raw material.
The range of mechanical properties of the product is wide, the formula can be adjusted in a large range, and the freedom of raw material selection is large. In addition to the common polyurethane and polyurea, it can also be applied to the processing and molding of epoxy resin, nylon, dicyclopentadiene, polyester and other materials.
By applying the in-mold coating (In mold Coating) technology, the surface treatment process is completed in one go without additional painting treatment, thereby simplifying the processing technology and reducing the manufacturing cost.
