2023-04-28 18:03:59 By : admin
Jinjiang dingxin mould CO., LTD., a leading manufacturer of high-quality molds, has been making an impact in the world of reaction injection molding, a technique that has revolutionized the production of thermosetting elastomers made from polyurethane. This technology has been instrumental in the manufacturing of an array of objects like automobile parts, industrial rollers, flexible molds, forklift tires, and various other products.

Reaction injection molding (RIM) is an innovative technique used to produce high-performance parts with a broad range of characteristics such as high impact resistance, good strength, and elasticity. The process is relatively simple, in which a two-component mixture of polyurethane resin and hardener is injected under low pressure into a mold cavity. The mixture reacts in the mold cavity, with the help of a catalyst, to create a solid part that is then removed from the mold. This process takes about 30 seconds or less, which makes it a time-efficient and cost-effective solution for many manufacturers.
