Rotational moulding basic process flow
To prepare materials for the rotomoulding process,plastic granules are reduced in size throughapulverizer.The materials can be colorized or modified with additives.
The material is fed into the mould in the exact weight of the product.Any parts to be mouldedinto the product,such as metal inserts,are now placed in the mould.
The mould is heated,which melts and compacts the material inside.During this sintering themould is rotated around two axes.This step in rotomoulding process creates a solid,uniformlayer.
During cooling the heated part is cooled down belowmelting temperature.The materialsolidifies inside the mould.This processdefines mechanical properties of the product.
Demoulding is removing the finished part from the mould.Any undercuts or threaded parts inthe mold are removed first.Now the mould is opened and the part can be released.
In this step of the rotational moulding process,the product can be machined by using specializedrouting tools.The final product is assembled,tested,inspected and packed.
