Hot melt molding: molding of pressure-­sensitive components

Contact us

HECHT + DIEPER is a tech­nologically leading com­pany in the injection moul­ding of plastics tech­nology. It has many years of engineering experience and by using the latest tech­nologies reaching from development, mould con­struction, to tool pro­duction and manufacture HECHT + DIEPER is able to manufacture innovative plastic products of the highest precision.

The development and production of plastic parts – reaching from conceptualisation to production takes place under one roof: A prerequisite for short development phases and high product quality.


We directly overmold electronic components.

HECHT + DIEPER realizes a tight overmolding of an antenna coil in a plastic carrier plate by using the hotmelt adhesive Macromelt. In this example, hotmelt molding based on polyamide offers a favorable alternative to conventional polyurethane- or epoxy resin-based potting compounds.

Unlike the classic plastic injection molding process, the hot melt is processed at a much lower injection pressure. The lower injection pressure has the advantage that electronic components can be directly overmolded without damaging them.


Hotmelt adhesives are processed at temperatures between 180°C and 240°C. They can be exposed to temperatures from -40°C to 140°C. The adhesion properties to PA, PBT or other polar plastics is very good.

Thermal potting materials made of polyamide are also advantageous from an ecological point of view, as they are made from renewable raw materials, no chemical reactions take place during processing and no solvents are released.
