Rotational moulding usually uses low cost materials (PE, PA, PP, PVC, PC).
The material specifications are governed by precise requirements: rigid/flexibile properties required by the part (surface properties), working temperature, colour and UV requirements. The use of materials other than those mentioned above requires a much more accurate process control.
In the last years the technology of rotational moulding is entered into many different fields that require highly technical parts and aesthetic finish. To meet these needs are produced steel sheets moulds, aluminum moulds CNC machined and casted.
