 Rotational Moulding

 Rotational Moulding Animation

Typical Products  
Rotational moulding is a process used for producing hollow plastic products. By using additional post-moulding operations, complex components can be produced enabling the process to compete effectively with other moulding and extrusion practices.

Rotational moulding differs from other processing methods in that the heating, melting, shaping, and cooling stages all occur after the polymer is placed in the mould, therefore no external pressure is applied during forming.

This provides the following advantages:

Economically produced large products
Minimum design constraints
Stress-free products
No polymer weld lines
Comparatively low mould costs
