ROTATIONAL MOULDING

Rotocasting machine also known as rotomoulding, rotomolding or spin casting, is a moulding process for creating many kinds of mostly hollow items, typically of plastic.

INDAC Ltd produce and stock a  range of plastic storage tanks ideal for storing water and other fluids. The tanks are rotomoulded and have no welded joints leading to a robust and fully sealed tank made in one piece, these tanks are made from food grade, UV Resistant, high impact polyethylene. These tanks can be supplied with innovative threaded Spinweld fittings of your choice.

Rotational moulding process

A heated hollow mould is filled with a charge or shot weight of material, it is then slowly rotated (usually around two perpendicular axes) causing the softened material to disperse and stick to the walls of the mould. In order to maintain even thickness throughout the part, the mould continues to rotate at all times during the heating phase and to avoid sagging or deformation also during the cooling phase. The process was applied to plastics in the 1940s but in the early years was little used because it was a slow process restricted to a small number of plastics. Over the past two decades, improvements in process control and developments with plastic powders have resulted in a significant increase in usage.
