Rotational moulding basic process flow


Step1 Material preparation

To prepare materials for the rotomoulding process,plastic granules are reduced in size throughapulverizer.The materials can be colorized or modified with additives.


Step 2 Loading

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.


Step 3 Sintering

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.


Step4 Cooling

During cooling the heated part is cooled down belowmelting temperature.The materialsolidifies inside the mould.This processdefines mechanical properties of the product.


Step5 De-moulding

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.


Step 6 Finishing &assembling

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.


Step 7 Waiting for delivery
At last,the products are waiting for deliver to customers warehouse.
