Designers and engineers have been quick to realise the potential for rotational moulding, particularly in applications that require hollow parts or complex shapes. Major advances in plastics technologies and in mould construction make the new process even more versatile and valuable.
A big factor in the growth of rotational moulding is in its adaptability for short runs and large scale production. Such is the scope of the process that it can mould products as small as a ping-pong ball, weighing just a few grammes, or as large as a 10,000-litre tank, weighing almost 300 kilogrammes. Kiel Industries has got you covered.
Unsurpassed Moulding Technique and Technology
Rotational moulding makes it possible to manufacture sophisticated parts and products in a variety of plastics. These parts can be made in complex shapes and different sizes. In fact, some of these parts would be impossible to produce through any other moulding process.

The process can be adapted to the customer’s needs and the designer’s imagination. The potential for rotational moulding is vast. It is versatile enough to create new shapes heading into the future. Kiel Industries is versatile.
Rotational moulding is used because it doesn’t require weld lines or joints, the end product is essentially stress free, it is inexpensive, manufacturing is relatively quick, economic short production runs are viable, there are no wasted materials, multi-layer products can be made and different product types can be used on a single machine.
The principal of rotational moulding of plastics is simple. Basically, it consists of introducing a certain amount of plastic (powder, granular, or viscous liquid) into a hollow, shell-like mould. Kiel Industries sticks to this principal.
The mould is rotated or around two principal axes at low speeds. It is heated so that the plastic enclosed in the mould forms against the mould surface. The rotation continues during the cooling phase so that the plastic retains its desired shape as it solidifies. When the plastic has become rigid, the rotation is stopped to allow the removal of the plastic product from the mould.
