Rotational moulding is a technological process that allows the production of hollow bodies in one piece without any welding. This technology allows the manufacture of pieces uniform in thickness and without any internal strains.

Large dimension and complex profile items can be moulded with several finishes -synthetic leather, embossing, etc. Co-moulded inserts could be also added.

Continuous search for new moulding materials and technologies enlarge every year the range of polymers efficiently used in the rotational process.
At present, linear and webbed polyethylene - e.g. pvc, polypropylene, polyamide, polycarbonates - are mostly used for rotational moulding production.

The distinguishing feature of rotational moulding technology is the mould rotation around two perpendicular axes, a fixed direction primary axis and a secondary axis with variable direction. Throughout the process (excluding the loading and unloading phases) the mould slowly and ceaselessly continues to rotate.

The mould rotation around two axes causes the softened polymer to disperse and stick to the internal walls of the mould. The finished piece is formed by depositing alternating layers of polymer fully melt.
Due to the slow rotational speed, the polymer doesn’t stick because of the rotating centrifugal force but being coalesced and adhering to the mould wall.
