What is Blow Moulding Process?
Blow molding ( BrE moulding ) is a manufacturing process by which hollow plastic parts are formed. The parison is formed by melted plastic material being pushed through an extruder. The parison is a tube-like piece of plastic with a hole in one end through which compressed air can pass. When the parison reaches a certain length, the two halves of the mould close around the parison sealing it at the bottom. Compressed air is then used to inflate the parison to form the shape of the cavity inside the mould.
Benefits of Blow Moulding.
- Blow Moulding is relatively High Production Process.
- Lower Product Weight resulting lower costs & hence better margin can be realized.
- Single Stage Process, Less Operational Costs, Simplified Operations.
- Better Product Aesthetics.
- Fully Automation.
