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
- 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
