Rubber injection machine PK rubber compression machine

Rubber injection molding machines and rubber compression molding machines are two different methods of molding rubber parts.

Injection molding is a process where rubber is heated and melted, then injected into a mold under high pressure. This results in a uniform, high-quality part with a consistent wall thickness. Injection molding machines are often used for producing large quantities of rubber parts with intricate shapes.

Compression molding, on the other hand, is a process where rubber is placed into a mold and then compressed under heat and pressure until it cures and takes the shape of the mold. This process is typically used for producing larger, simpler parts with a uniform wall thickness.

Both methods have their advantages and disadvantages, and the choice between them often depends on the specific requirements of the part being molded and the production volume. For example, injection molding is typically faster and more efficient for high-volume production, while compression molding is often more cost-effective for lower-volume production or for producing larger parts.
