Rubber Injection Mold

The Rubber Injection Mold produced by Xiamen SLD Rubber Factory is manufactured using high-precision processing technology. Through precise cavity design, optimized flow channel system and efficient temperature control structure, it can stably inject liquid rubber materials into precise rubber products that meet the design requirements. We ensure that each injection molding process can produce rubber parts with accurate dimensions and perfect appearance.

Parameter

Advantages and Features

This Rubber Injection Mold pursues an extremely high molding accuracy and long service life. Its greatest trump card is that it can ensure the continuous production of tens of thousands of products, with almost exactly the same size and appearance, and the mold itself is very durable, capable of withstanding millions of mold opening and closing cycles. We use high-quality mold steel and subject it to strict heat treatment and surface treatment to ensure that the mold has high hardness, high wear resistance and high toughness.

Why choose us?

The Rubber Injection Mold of Xiamen SLD Rubber is an essential tool for achieving high precision and efficiency in the production of rubber products. Through reasonable structural design, selection of high-quality mold materials, precise manufacturing, and strict debugging control, we can meet the large-scale, high-stability production requirements of rubber seals, shock absorbers, and functional rubber products in industries such as automobiles, industry, medical, and electronics.

FAQ

What materials are used? How long is the lifespan?

The Rubber Injection Mold includes P20, 718 and H13. The production lifespan can reach over 200,000 to 500,000 mold cycles.

Why is shrinkage rate a necessary consideration in mold design?

Volume contraction occurs after vulcanization cooling. Different rubber species, such as NBR, EPDM and FKM, have different shrinkage rates, which need to be accurately determined by empirical formula or test model data.

Why is the exhaust design of injection molds so important?

If the air and volatile substances in the cavity cannot be discharged in time, they will be compressed and generate high temperatures, which may cause defects in the product or hinder the filling of the rubber compound, resulting in a lack of rubber. Reasonable design of exhaust grooves or pin clearance is crucial.

How does temperature affect the product?

Excessive temperature will cause the product to over-sulfurize, become brittle or have difficulty in demolding. Insufficient temperature will result in insufficient sulfuration, the product to become sticky or fail to meet the mechanical performance standards. Generally, the temperature of the injection mold is controlled between 160℃ and 185℃, depending on the specific formula.
