At present, the trend of injection molding process is developing towards high and new technology. These technologies include micro injection molding, high filling compound injection, water assisted injection molding, mixed use of various special injection molding processes, foam injection molding, mold technology, simulation technology and so on. Each kind of plastic has different flow temperature. Due to different sources or brands, the flow temperature and decomposition temperature of the same plastic are different, which is due to different average molecular weight and molecular weight distribution.

The plasticizing process of plastics in different types of injection machines is also different, so the barrel temperature is also different. Injection molding company specializes in the production of power tool parts, medical equipment parts, electronic product parts and home appliance parts. Hollow blow molding is to place the plastic parison in high elastic state (close to viscous flow state) in the mold cavity.

How much is it for hollow molding? Blow it with compressed air to make it close to the cavity wall. After cooling and shaping, the molding method of hollow plastic parts is obtained. It is mainly used to manufacture hollow plastic containers such as bottles, barrels, cans and boxes. There are many methods of hollow blow molding, mainly including extrusion blow molding, injection blow molding, deep drawing injection blow molding, sheet blow molding and multi-layer blow molding.
