About Roto Moulding

In plastic industries, there are mainly three types of process Widley uses: Injection moulding, blow moulding & Extrusion moulding. The main disadvantage of these process is high machine & mould die cost.

Rotomoulding process is widely uses to make small or large size hollow & Seamless products.

Rotational molding also known as rotomolding or roto casting. Roto moulded product is a thermo plastic products.

Rotomoulding process passes through mainly 4 stages as below Loading material heating.

The main advantage of Rotational moulding process is as below

• Hollow plastic products can be made with low levels of residual stresses
• High tensile strength, seamless product, equal wall thickness and law processing cost.
• Mould or die cost is not too much expensive
• There is no material wastage in the process. almost full charge of material is consumed in making the part
• It is possible to make multilayer products
• Different types of products can be moulded together on the one machine
• Inserts for inlet & outlet are relatively easy to mould in.
