Plastic Moulded

olymer powder is manually loaded into the mould which is then closed and shifted to the heating oven. Here, the mould is heated using forced hot-air circulation. While being heated, the mould is rotated in two perpendicular axes simultaneously. The polymer then melts and forms a homogenous layer within the mould. The mould is then shifted to a cooling station where forced air is used to cool it. Finally, the mould is opened and the moulding is removed. Unlike injection and blow moulding, rotomoulding does not involve high pressure; hence, products are stress-free and the walls are of uniform thickness.
