Qiaolian machine is the brand for machinery of Siwarde group.We have been committed to the development and research of PC/ABS/PMMA sheet,silicone and rubber forming equipment more than 10 years.We have much experience in manufacturing compression molding machine,vacuum compression molding machine,rubber injection molding machine,LSR injection molding machine,extrusion machine,banbury mixer and mixnig mill machine,as well as related technologies.
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.
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.
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.
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
