Direct moulding of apertures

Modelmakerij Hengelo develops insulation material that can be inserted in the mould wall, for instance. This enables the direct rotomoulding of apertures in plastic products. Post-processing of the products is therefore no longer necessary, while messy filings are a thing of the past.


The frames surrounding the mould are constructed using a unique clamp. This patented clamp, which we developed ourselves, vouches for the perfect closure of the mould.
