What is the process of blow Moulding?
Blow molding is the forming of a hollow object by inflating or blowing a thermoplastic molten tube called a “parison” in the shape of a mold cavity. The process consists of extruding or “dropping” a parison on which female mold halves are closed. The female mold halves contain the shape of the product to be produced.
How much does a blow molding machine cost?
A single cavity, extrusion blow mold suitable to produce up to 100M units per year may cost as little as $3,000. An eight cavity, extrusion blow mold with automatic detabbing equipment may cost as much as $25,000 but may generate sufficient cost savings to return the investment within a short period.

What are the advantages of blow Moulding?
What are the three main types of blow molding processes?
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 molding (ISB), a preform.

What are the disadvantages of blow molding?
Disadvantages of blow moulding
- Limited to hollow parts.
- Low strength.
- To increase barrier properties, multilayer parisons of different materials are used (thus not recyclable)
- Trimming is necessary to make wide neck jars spin.
- Limited to thermoplastics (rotational moulding can be used with thermosets)
