Blow Moulding, that is, with the aid of compressed air on high elastic or plastic state of hollow plastic parison swell deformation occurs, then the cooling stereotypes, get known as blow molding Plastic Products processing methods. According to the type of blowing products, this method can be divided into hollow blow molding and film blow molding.
1. Hollow blow molding
Hollow blow molding, needs to be high elastic state or in a plastic state of hollow plastic parison in the blow molding of the closed cavity, and then to the compressed air for its internal access, to force expands its surface area (blowing) and stick close cavity wall, and then the cooling stereotypes can get a certain shape and size of the hollow plastic products. Suitable for all kinds of bottles and cylindrical plastic containers.
2. Film blow molding
Film blow molding is using extruder melting plastic molding for thin-walled tube billet after pipe blowing in from the center to the compressed air, forcing the pipe blowing bulge deformation at high temperature and becomes a tubular membrane (bubble shell), bubble tube under the action of the traction movement between roller crushed all lamination, and then through the drawing roller, winding roller guide roller arrive, take the scroll roll winding become film products, suitable for all kinds of packing plastic bags.
2. Blister molding
The vacuum molding is also called vacuum molding, which belongs to the forming range of sheet.
