Why Rotational Moulding?
Rotational moulding has many benefits over other moulding processes including:
- Product strength- Create seamless products with no joints or welds — perfect for strong, hollow components.
- Lower tooling costs- Simpler mould design means lower upfront investment.
- Short run friendly- Cost-effective for low to medium production volumes.
- Variable wall thickness- Adjust wall thickness to meet performance or weight requirements.
- Moulded-in metal inserts- Add threads directly into the part during the moulding cycle.
- Flexible colour changes- Change colours from cycle to cycle with minimal cleanup — ideal for product variety.
