This is one of the most common processing methods and is achieved by injecting polypropylene in a molten state into a mould, which is then cooled to form the product of the desired shape.

 

This is one of the most commonly used processes. It is suitable for the production of small or medium-sized parts with complex shapes.

 

Blow moulding:

 

mainly used for the production of small or medium-sized parts with complex shapes.

Blow moulding: This is mainly used for the production of hollow products such as bottles, containers, etc.
containers, etc. The process is to place the plastic blank heated to semi-molten state in the mould, and then pass compressed air to make its

The process is to put the heated semi-molten plastic parison in the mould, then pass the compressed air to make it expand and fit into the mould cavity, and finally cool and shape.

 

Extrusion moulding:

 

It is suitable for making continuous products such as pipes, plates and films.
products. The principle is that molten polypropylene is extruded through a mould of a specific shape and subsequently cooled and cured.

Thermoforming:

 

Polypropylene sheet is heated above the softening point and then
Vacuum or pressure is used to make it adhere to the surface of the mould, and the finished product is cooled.

 

After cooling, the product is finished. Commonly used to produce large or specially shaped parts.
