Rotational Moulding

Your OEM partner in Rotomoulding

Rotational moulding, also known as rotomoulding, can be used to manufacture a diverse range of products. It involves the use of sophisticated plastics moulding technology and is most often used to make hollow goods, such as hard plastic cases for storing electronic equipment, bins and containers and children’s toys.

Rotational moulding is a popular method of manufacturing due to its affordability and is used by a wide range of industries, as it delivers a precise finish on every product.

At Trifibre, we have invested in the best technology and use the highest quality materials to develop hard wearing and durable products via our custom rotational moulding service.

The Rotational Moulding Process

Loading

Raw material is placed into the mould. The most common material being polyethylene (LDPE, HDPE, LLDPE, MDPE) which is available in a vast array of colours. Additives can be added for different requirements such as UV protection and colour consistency.

Heating

The mould is then heated in an oven and rotated causing the polymer to coat the mould walls. Rotation occurs on two or more axes rotating at different speeds and frequencies. This allows for an even wall thickness and clean finish.

Cooling

After heating, the mould is cooled whilst rotating to ensure an even wall thickness. During this time the product will incur a small amount of shrinkage which is catered for in the design of the mould. The shrinkage aids the removal of the product from the tool.

Removal

The final steps in the rotomoulding process are removal of the product from the tool and finishing. During the finishing process the parts are trimmed and allowed to cool further sometimes using jigs to prevent further shrinkage and to achieve an accurate final product.


What are the benefits of rotational moulding?

There are numerous benefits to using plastic rotational moulding for your products. It is an affordable manufacturing process that delivers a uniform finish and an end product that is strong and resilient, while providing complete design freedom and the ability to create highly complex shapes…

Durable and Reliable

Products made using rotational moulding are inherently reliable, internal stresses are minimal and joints are eliminated. The materials are tough and resilient even under extreme conditions when compared to fabricating, fibre glass, injection, vacuum or blow moulding.

Unlimited Design Possibilities

Offering the opportunity to manufacture stress-free parts with uniform wall thickness and complex shapes. The process is extremely versatile. Parts can be manufactured with inserts moulded in and surface textures and effects reproduced with relative ease.

Low Cost

The tooling used in rotational moulding is produced from either steel or aluminium and is relatively low in cost when compared to tooling used for other processes, such as blow or injection moulding. Plus, all of our rotational moulding products are UK-made and manufactured.
