Rotomoulding is a process that consists of the following four steps:



  • A weighed portion of plastic, usually in powder form, is poured into the open mould. If the material was not colored before being ground to powder, it is dry mixed: the dye in powder form is mixed with the material powder before loading.


  • The mould is already closed, it is heated depending on the type of machine, the powdered material turns into a liquid and adheres to the surface of the mould walls. The most frequently used mould closures are the quick-release clamps.


  • The mold is cooled at the moment when the stage of uniformly covering its walls with material to a specific thickness of the product wall is completed. The material then solidifies or hardens to the desired shape.


  • After the material has cooled down to a temperature where it maintains a constant shape, it is possible to take out the product without deforming it. The mould is opened and the article is removed from it. Then another weighted portion of polyethylene powder goes into the mould and the process repeats.
