Abstract

Blowmoulded PVC flasks These are made from a hot extruded blank whose outer skin is allowed to cool to maintain stability of shape. Inner layers are still hot. For blow moulding purposes the material is allowed to arrive at equal temperature througout. The blanks for blow moulding travel from the extruder to the blow moulding heads through a hollow chute and they fall on blow moulding heads which travel to a moulding station.
