Rotational Moulding – Which materials?
Rotational Moulding – What Products?
Design for Rotational moulding
- Wall thickness: The wall thickness of the part should be consistent throughout to ensure even heating and cooling during the moulding process. Varying wall thickness can cause warping and deformation.
- Draft angles: Draft angles are used to allow the part to be easily released from the mould. A draft angle of at least 1 degree per inch of wall thickness is recommended to ensure proper release.
- Ribs and gussets: Ribs and gussets can be used to reinforce the part and prevent warping. They should be designed to allow for even heating and cooling during the moulding process.
- Undercuts: Undercuts can make it difficult to release the part from the mould. They should be avoided or designed to allow for easy release.
- Mouldability: The part should be designed to be easily moulded using the rotational moulding process. This includes avoiding sharp corners or edges, designing parts with a uniform thickness, and ensuring that the part is balanced and symmetrical.
- Materials: The material used for the part must be compatible with the rotational moulding process. It should also be able to meet the desired end-use requirements, such as strength, flexibility, and durability.

Sheffield Business Award – Manufacturing
The last week in September proved quite a week for our group of companies: The Poly Group.
Whilst the management team were busy manning the stand at the Interplas UK Exhibition at the Birmingham NEC, our director, Julie Garner was busy attending The Star Sheffield local business awards, of which we won The Small Business Manufacturing Award! Having had a successful exhibition, Julie promptly drove down to the NEC to have a celebratory night out with the management team, and what a celebration it was! We are thrilled to have won the award, after what have proven to be, some of the most difficult couple of years for businesses throughout the UK and we would like to thank all the members of our team for the resilience shown and dedicated hard work, of not only, ensuring the company has operated to the best of its capabilities, but also, winning an award in the midst of it all. The Poly Group comprises of: Innovate Mouldings UK Ltd, Poly Plas Engineering Ltd, Poly Truck, Pedigree Pools and Viper Vivs.
