What Is Injection Rubber Molding?
Rubber injection molding is a manufacturing process where rubber is injected into a custom mold under high pressure, then heated to cure and harden into the desired shape. This method produces precise, durable, and complex rubber parts with consistent quality, making it ideal for both low-volume and high-volume production. It’s commonly used to create parts like seals, gaskets, and other custom rubber components across various industries, including automotive, medical, and consumer goods. Injection rubber molding offers exceptional design flexibility, the ability to use a wide range of rubber materials, and ensures high production efficiency, making it a preferred choice for manufacturers.| Name | Detail |

Material Preparation
Injection Molding
Curing or Vulcanization
Cooling and Ejection（Demolding）
After curing, the mold is cooled, solidifying the rubber part. Once cooled, the mold is opened, and the finished molded rubber parts are ejected. Excess material, such as flash, is trimmed off to ensure a smooth finish.
