Frequently Asked Questions
What are the benefits of 2K overmoulded in-vehicle buttons?
2K dual-colour overmoulding integrates two different plastic materials into a single part. This process ensures wear-resistant symbols, enhances tactile feedback, and provides excellent backlighting quality for modern vehicle interiors.
How does soft-edge trim improve automotive dashboards?
Soft-edge trim offers a premium, soft-touch feel to the dashboard surface. It helps eliminate sharp edges, improves passenger safety, minimizes cabin noise by absorbing vibrations, and ensures seamless fitment between interior panels.
What does the IP67 rating mean for the ECU silicone sealing ring?
An IP67 rating means the ECU housing is completely protected against dust ingress and can withstand temporary immersion in water up to 1 meter deep. The overmoulded silicone sealing ring ensures a durable, leak-proof bond directly on the plastic housing.
Why is overmoulding used for cigarette lighters and charging port rings?
Overmoulding allows the integration of soft, flexible dust-proof rings directly onto rigid port structures. This creates a superior seal that prevents dust, debris, and moisture from entering electrical connections, extending the lifespan of the ports.
What materials are typically used in automotive overmoulding processes?
The process commonly combines rigid substrates like Polycarbonate (PC), ABS, or Polyamide (PA) with flexible elastomers such as Thermoplastic Elastomers (TPE), Thermoplastic Polyurethane (TPU), or Liquid Silicone Rubber (LSR).
