PVC Blow moulding

Blow molding is a manufacturing process by which hollow plastic parts are formed.

In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding. The blow molding process begins with melting down the plastic and forming it into a parison or in the case of injection and injection stretch blow moulding (ISB) a preform. The parison is a tube-like piece of plastic with a hole in one end through which compressed air can pass.

The parison is then clamped into a mold and air is blown into it. The air pressure then pushes the plastic out to match the mold. Once the plastic has cooled and hardened the mold opens up and the part is ejected.

Take a look through our standard range of PVC blow moulding compounds to see if there are any that suit your requirements. If you want further information on any of the compounds or should you wish to talk through your PVC blow moulding requirements with one of our technical team then please just give us a call.
