Compression molding machine | What is compression molding

Compression molding, also known as compression molding, compression molding, etc., is the powder or loose granular solid plastic directly added to the mold, through the heating, pressurization method to make them gradually soften and melt, and then according to the shape of the mold cavity molding, cured into plastic parts, mainly used for molding thermoset plastics, can also be used for thermoplastics. Compared with injection molding, the advantage is that ordinary hydraulic presses can be used and the compression die structure is simple (no pouring system).

Vacuum Compression Molding Machine

Vacuum compression molding machine consists of two parts, vacuum molding machine and automatic mold release system. Both sections are connected to the automatic mold handling unit and are sorted by press operation. The machine is operated automatically, which saves a lot of time.

Silicone Compression Molding Machine

Silicone molding process Silicone molding molds are preheated before vulcanization. Place specific raw materials into a cavity. The mold tool then shuts down and the compressor applies pressure to the mold.

Compression Rubber Molding Machine

The manufacturing process for rubber and silicon products includes material preparation, chewing, mixing, preforming, cutting, calendering, vulcanization and processing steps. Each step requires specific equipment and technology to complete. Vacuum compression molding machine is an industry that produces rubber or silicone parts such as O-rings, seals, keyboards, connectors, bushings, rubber medical products, etc.

Frequently Asked Question

Do you have any question?

Compression molding is a molding process in which a plastic material is placed directly into a heated metal mold and then softened by the action of heat, forcing it to conform to the shape of the mold when the mold is closed. After the molding is complete, excess flashes can be removed.

Advantages of compression molding It's a much simpler process. It involves lower tool costs. It is ideal for the production of large items and thicker parts. It can be a good choice for insert molding and multicolor molding. It is cost-effective for short-term production runs. It has a higher post-molding cost opportunity
