How much is Dalian hollow molding? Common materials for molding plastic products include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polystyrene (PS), polycarbonate (PC), etc. in addition, there are linear low-density polyethylene (LLDPE), high molecular weight polyethylene (HMWPE) and other resins. After the product is formed, it is cooled and contracted to wrap the core. In order to facilitate demoulding and avoid top white, top injury and drag white, a certain demoulding slope shall be set on the inner and outer wall surfaces of the product parallel to the demoulding direction.

Professional hollow molding manufacturer, demoulding slope is related to rubber performance, rubber part shape and surface requirements. Molding plastic products containing lubricants, plasticizers, etc. the demoulding slope can be smaller than those without. In the development process of hollow plastic molding machine in China, extrusion blow hollow plastic molding machine is a fast developing and perfect hollow plastic molding machine, especially the small extrusion blow hollow plastic molding machine.

Hollow plates can be recycled, etc. There are two key points in hollow forming planning. One is to take structural adjustment as the main target and important starting point for changing the development mode. At the same time, we should also pay attention to the application of plastics in vehicles, ships, aerospace and other aspects, so as to further broaden the development space of plastic processing industry.
