In this article we learn the topic Blow Moulding Process, Applications, Advantages and Disadvantages in manufacturing so let's see the further information,
Blow Moulding Process, Applications, Advantages and Disadvantages
This process is used primarily for producing thin walled Holloway containers from thermoplastic resins.

| Blow Moulding Process |
The process begins with the extrusion of a continuous heated cylinder of plastic material called parison. This parison is cut to proper length, placed between two halves of a muold and blown to required shape by air pressure.
When the two parts of mould are closed the parison is pinched off and the material is forced by air pressure against the mould surfaces. Vents are provided in mould to allow the entrapped air to escape and the walls of the mould are cooled to set the plastic. After the product is set the mould halves are separated to remove the product. More thermoplastics can be blow moulded but the walls of product can not be held to very accurate thickness because different parts stretch differently.
Advantages
1) Rate of production is fast.
2) Recycling.
3) Cost is low.
4) Productivity is high.
Disadvantages
1) Difficult to produce complex parts.
2) Impact on environment.
Applications
In blow moulded products include bottles floats, jars, containers, automobile heater ducts, plastic mugs, cups etc.
So in this article we see the Blow Moulding Process, Applications, Advantages and Disadvantages ,information hope you understand best.
