The Plastic Bottle Mould

1.The material is Steel or Stainless steel 2.High quality 3.Mirror polishing Techinical 4.The Blow Moulding Machine

1.Blow Molding is obtained by extrusion or injection system, still in a plasticized state,

tubular or sheet blank material trend is fixed in the mold, and immediately pass into the compressed air, forcing the billet material expansion and affixed to the mold cavity wall surfaceWhen the cooling setting mold release, ie the required hollow products as a processing method. Suitable for blow molding plastic, low pressure polyethylene, hard PVC, soft PVC, polystyrene, polypropylene.

2. polycarbonate and other high-pressure polyethylene. Is divided into the parison molding method, blow molding extrusion blow molding blow molding and injection blow molding blow molding two.

3.Extrusion blow molding extruder and extrusion blow molding of a simple structure, shortcomings of the parison wall thickness inconsistent, likely to cause the unevenness of the wall thickness of the plastic products.

4.The right is a schematic diagram of the extrusion blow molding blow molding principle.

5.The advantages of injection blow molding blow molding the parison wall thickness, no flash, and the injection parison underside, the hollow bottom of the products will not fight and sewing is not only beautiful 6.and high strength.

The disadvantage is that the molding equipment and molds used in expensive, so this molding method used for the mass production of small hollow products, use wide range of extrusion blow molding method.
