Overmoulding plastic insulation

This technology is an extension of our technology of stamping and packaging blades.

Our competences include:

·        Overmoulding plastic insulation of rotor or stator stacks with straight or slanted poles and with or without compensation

·        Thin-wall insulation

·        Sigmasoft software for simulations

·        In-house tool design and manufacturing

·        100% insulation quality testing

·        Linked stamping and injection moulding technologies

ISO 13485 certified, ensuring top-quality, safe laboratory equipment

All certificates
  • This technology is used for products in the automotive,
  • HVAC and
  • garden power tool industries.
  • EC motors are used in all three areas.


The combination of stamping and overmoulding is our key competence, and a competitive advantage for our customers:

•        Overmoulding insulation of stator stacks with straight or slanted poles and with or without compensation (PA, PBT, PET etc.)

•        Sigmasoft injection moulding simulation

•        This technology also enables high-quality and reliable insulation for high-voltage applications

•        Excellent thermal conductivity, with greater design freedom for high voltage and media resistance

•        Two different heights of overmoulded stack – one tool

•        Tools are designed and produced in-house

Advantages of overmoulding technology compared to standard paper insulation:

·        Only one tool for complete rotor or stator insulation (between the poles as well as top and bottom)

·        Improved thermal conductivity

·        Simplified motor winding

·        Cost efficiency
