Co-extrusion Blow Moulding Machine

Multilayer co-extrusion blow molding is the technology of making hollow container by blowing molding. It uses more than two extruders to melt and plasticize the same or different plastics in different extruders. And then compounding, extruding and forming multi-layer concentric composite parison in the die.In extrusion blow molding a plastic material feedstock is fed through a hopper onto a feeding transfer screw. This feeds material into an especially designed blow molding die that directs the material flow to create an extruded hollow tube called a parison.Blow molding machine is also known as hollow blow molding, is a kind of rapid development of plastic processing methods. Blow molding machine is a machine which blow the plastic to the mould cavity with certain shape using wind when the liquid plastic start to spry out.
