Roto-moulded Water Tanks
A wide range of storage tanks from 4 to 5,500 litres. Most commonly used as water storage tanks but suitable for a variety of uses including chemical storage, please contact us for more information. All our storage tanks are rotationally moulded polyethylene that creates a high quality, tough and durable product that will provide many years of use.
Rotational Moulding Process
Rotational moulding (often referred to as Rotamoulding or Rotomoulding) is a process used for producing hollow plastic products. It 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.
The process involves charging the hollow tool with a carefully predetermined quantity of resin powder and placing this into an oven which is then rotated slowly about two axes.
Resin heats up to the required temperature, fuses and adheres to the inner wall of the moulding tool, thereby taking its shape. Following a brief curing period, cold air (and sometimes water) is aimed at the mould which releases the plastic from the metal tool prior to remould.
