The rotational moulding process: Where it all began

Possibly the earliest exponents of the process were the Chinese, for it is believed that the Rotational Moulding process, in principle,was used to mould the Terracotta Army of Emperor Qin Shihuang in the 3rd century BC.

However, industrialisation of this process for use with plastics really began in the USA in the early 1940's- where items such as dolls heads and play balls were produced in PVC.

A little later in Europe the early pioneers in Rotational Moulding had to work with home-made machines and plastic resins developed for the Blow Moulding industry. In those days Rotational Moulding was only used to make tanks and very simple plastic products using basic tools usually made from sheet steel.

In recent years improvements made in plastics technology, advances in mould construction, resin properties, and machine sophistication have combined to increase the versatility of Rotational Moulding dramatically. The process remains ideally suited for the production of hollow, seamless parts, but the many advances made have extended its capabilities enormously.
