Tool Making


Rubber molding is a highly efficient process that involves the creation of rubber products through the use of molds. The process entails melting rubber into a molten state and then pouring it into a mold to achieve the desired shape. The rubber mold industry is highly specialized, and the products that are created using this process are used in various industries, including automotive, construction, and medical equipment.


Types of Rubber Molds

There are two main types of rubber molds, including compression molds and injection molds. Each type of mold has unique features that make it suitable for specific applications.

1.Compression Molds

Compression molds are used to create simple rubber products that require minimal detail. The process involves placing uncured rubber material in a mold and then using heat and pressure to cure the rubber. The heat and pressure applied to the mold are used to create the desired shape and texture of the rubber product.

Compression molds are commonly used in the production of rubber gaskets, seals, and other simple products. The molds are made of high-quality steel, which ensures that the molds are durable and can withstand the high heat and pressure required during the molding process.

2.Injection Molds

Injection molds are used to create more complex rubber products that require high precision and accuracy. The process involves injecting molten rubber material into a mold under high pressure. The mold is made up of two halves that are designed to fit together perfectly, and the molten rubber is injected into the mold through a small hole.

The high-pressure injection of the rubber material ensures that the rubber product is formed with high precision and accuracy. Injection molds are commonly used in the production of automotive parts, medical equipment, and other complex rubber products.
