Rotomolding powder

Rotational Moulding, also called Roto Casting or Roto Moulding is a unique process because the heating, shaping and cooling process take place inside a mould with no application of pressure. The process is carried out at the ambient pressure, which makes the products withstand environmental stress and crack resistant during use.
A predetermined quantity of blended polyethylene resin powder is placed inside a cold mould (usually of aluminum or steel sheet metal).
The mould is then rotated (Bi Axially) and gradually heated inside the oven. As the metal mould gets heated, the polymer resin powder melts and the molten resin eventually get distributed (Coated) along the inner surface of the mould. When all the powder has melted & distributed, the mould is transferred to a cooling chamber keeping the mould rotating.
