What is Rotomoulding

Rotational moulding is a process used to manufacture hollow plastic products from simple to very complex shapes. Rotational molding has many advantages in terms of relatively low levels of residual stresses and inexpensive molds. Rotational molding also has few competitors for the production of large (> 2 m3) hollow objects in one piece. The process is best known for the manufacture of rainwater tanks but it can also be used to make complex medical products, toys, leisure craft, and highly aesthetic point-of-sale products. The rotomoulding process transforms plastic from either powder, pellet or liquid form into products in four major steps. The mould is heated, rotation takes place on two axis, the mould is cooled and emptied then refilled for the next cycle. Major international designers have use rotational moulding to produce stunning products for hundreds of different sectors.
