About Rotational Moulding

Rotomoulding offers relatively low tooling costs, economical short runs and ability to cope with large moulds. It is ideally suited to new product development and prototype work can be carried out without vast expense.

The process of rotomoulding is essentially very simple and can be broken down into four key stages. Feel free to use this website to learn more about this moulding technique.

	The metal mould is filled with a predetermined quantity of polymer powder, closed, clamped and then passed into an oven chamber.
	The mould is heated externally to a high temperature and rotated around both vertical and horizontal axis. As the powder inside heats up, it begins to melt and adhere to the inner surface of the mould. This continues until an even layer of molten plastic is formed over the surface of the mould.
	In the cooling chamber air is directed at the mould and in some cases water jets are used. When the plastic inside the mould has become solid, the mould can be removed from the chamber.
	The plastic component is then removed from the mould and allowed to finish the cooling process unrestricted by the mould. Cycle time can vary from 20 minutes to one hour. The plastic is formed without pressure and as a result has no moulded in stresses.
