Plastics | Rotational Molding

Enabling Quick Corrective Measures

The rotational molding process is a specialist technique used in the manufacturing of plastic parts and is primarily used for larger objects. Here a negative mold is fi lled with a powdered or liquid raw material such as PE or PP and then sealed. The mold is then heated in an oven to a maximum of 320°C and rotated biaxially. This causes the material to stick to the mold, layer by layer. The mold is subsequently cooled in a chamber and the plastic part removed. Upon opening the mold, the product is thermally tested to allow the production process to be readjusted if necessary.

Process temperature: up to 320 °C
