The process is divided into feeding, mold closing, exhausting, curing, demoulding and mold cleaning. If the product has inserts that need to be sealed during molding, the inserts should be placed before adding materials. The main controlled process conditions are pressure, mold temperature and molding time. In addition, there is a special form of molding method, which is to compact the powdered plastic first, then take out the blank from the mold, heat it in a furnace to the melting point, so that the plastic particles melt into a whole, and after cooling, the finished product or semi-finished product is obtained . This method is called sintering molding and is mainly used for the molding of polytetrafluoroethylene.
Hydraulic Press Die Casting Machine Application:
The die casting machine is mainly suitable for manufacturing various products such as polyvinyl chloride (PVC), polystyrene (PS), polypropylene (PP) and other roll films, vacuum blister, plastic chair, plastic basin, plastic washboard and plastic compression molding.
Fields of application
Hydraulic presses are mainly used in a variety of industries such as metalworking, plastics processing, and automotive manufacturing, where their stable pressure and flow ensure efficient and precise operations. Die casting machines, on the other hand, focus on automotive, electronic components and other fields, injecting molten metal into molds through high pressure to efficiently produce complex parts.
