A manufacturing process that forms hollow plastic and glass parts, such as bottles and jars.
This process can be separated into three varieties:

Injection Blow Moulding:

This is normally used on smaller-scale production runs and follows the same principles as injection moulding, but changes in the finishing process, when the plastic is rotated and has air blown into to it to create a hollow shape. This method is the least common method used in Blow Moulding.

Extrusion Blow Moulding:

This process requires the plastic to be extruded downwards. When it reaches the correct length, the mould closes, the neck is held open and the bottom is pinched closed. A blow pin is then inserted into the hot plastic, and the plastic is blown to fit the shape. The product is then ready for the final finishing processes.

Stretch Blow Moulding:

Stretch Blow Moulding is used for products that require clarity. First, the product is injection moulded into a preform. These preforms are then placed and clamped in the machine, then they are taken to high heat and blown to form the product. This is a fast and common process in Blow Moulding.

Blow Moulding is commonly used in bottle making, jars, medical and scientific vials/bottles.
