RUBBER MOLDING

Rubber products are ubiquitous in nearly every industry nowadays. They play a vital role in functions like sealing, abrasiveness, insulation, etc. As a result, they are critical in upholding high industry standards and development in today’s fast-paced world. There are several methods to manufacture rubber products, rubber molding being one of them.

Types of Rubber Moulding

Different Types of Rubber Molding Process

Rubber molding is a diverse manufacturing method with lots of variants. Each type has its own specialized production procedure, advantages, and disadvantages. We will present a detailed summary of the most well-known ones compression molding, and transfer molding.

Rubber Injection Molding

Rubber injection molding is very similar to the more well-known plastic injection molding process. It starts with the uncured rubber strips that go into the machine via a hopper. Once through the hopper, it enters the screw chamber, where it is heated and compressed by external heaters and friction from the movement of the screw.

Near the end of the screw, the rubber has heated to a very fluidic state. It is fed into the mold at high pressure and it fills up the cavity built inside the rubber mold. Due to its flow properties, the rubber material fills every nook and cranny of the cavity.

The mold then gradually cools down so the rubber solidifies. Finally, the mold opens to eject the end product, after which it is ready for the next cycle.
