Rotational moulding - stable products without built-in stress
There are many advantages of rotational moulding;
Greater freedom in product design allows the product to be tailored.
The product will be in one piece without joints makes the risk of cracks and leaks are minimized.
Limited tooling costs for the mold makes it cost-efficient even in smaller series.
Possibility to build in many functions provides cost-effective solutions.
Materials with very good chemical resistance that is also recyclable.
Materials with a wide temperature range.
Low weight in relation to the size of the product.
Corrosion-free products.
The process begins with the material dispensed in a mold of steel or aluminum. Common materials are polyethylene, polypropylene and polyamide. Final product thickness is determined by the amount of material dosed. It also installed the embedded components should be in the final product.
The plastic material melts during heating in the own. The double rotation distributes the material to the correct thickness.
In the cooling chamber the melted plastics shrinks and teleases from the mould walls.
The mould is opened and he product is forwarded to assembly stations
