Plastic blow molding is a manufacturing process that allows you to produce and form hollow products very efficiently. There are a variety of forms of plastic blow moulding as can be seen below:

Extrusion Blow Moulding

In Extrusion Blow Molding, plastic is melted and pushed through an extruder to form a hollow tube (parison). When this parison reached a specified length, two halves of the mould close around the parison sealing it at the bottom. Compressed air is then blown into the parison, inflating it into the shape of the mould, usually a bottle, container or part. The plastic then cools and the product is removed.

Stretch Blow Molding Process

In stretch blow molding is generally used for the production of high volume and quality bottles/containers. This process begins with the injection moulding process to create a “preform”.  These performs are produced with the necks of the bottles, including lid threads on one end. When the preform is ready for be stretched/blown into the desired shape, they are heated and blown using high pressures of air. This process can also be performed in a single stage process.

Injection Blow Molding

Injection blow molding is the least common method of blow moulding. In this method, the polymer is injected onto  a core pin, then the core pin is rotated to a blow molding station to be inflated and then cooled. The product is then released from the machine.
