Understanding the Process of Rubber Injection Molding

There are two types of rubber available in the market: these are the natural and synthetic rubber. Rubber has been around for more than hundreds of years now and it has already been used by most of the industrial companies in creating different kinds of materials. Since rubber has played an important role in our life, the process of creating it has been improved using the rubber injection molding.

The main function of rubber injection molding is to process rubber parts, which is being used in machines and other mechanical parts. It comes in different sizes that will fit in various components. It is usually found in press shop and other industrial companies.

The process used in rubber injection molding is not that hard because it will all depend to the machine. The process will begin by acquiring the rubber’s design using a mold that is made from a metal that has an exact size and dimension as the rubber part. This mold is being inserted in a press that is connected in a system called the rubber injection. Once the mold is already inserted to the press, appropriate pressure is being applied. The rubber will be injected to the mold using a screw or a large ram. Through the nozzles, it will be passed into the mold cavity where it is being cooled down. As the process of cooling the rubber goes, it will slowly separate from the mold, while it acquires the design of the mold.

Rubber silicone molding parts does not have any heater elements applied. The process of injection press allows the rubber to acquire the specific design of the mold, which is commonly made from stainless steel. There are two types of rubber injection molding these are the vertical and the horizontal molds. Both have their own advantages and disadvantages when it comes to its process.
