Steering column switch housing made from polyamide 6
- Material changed directly in the series tool
- Cost-effective component solution with weight saving
- Strict requirements regarding dimensional tolerance fulfilled
Advantages due to foaming
The housing is injection molded from foamed polyamide 6. This foaming process has several advantages. In comparison with solid components, it saves material and weight – with reasonable compromises in terms of mechanical characteristics. “The use of foam injection molding with our material results in a weight reduction of close to 10 percent,” said Helbich. In addition, foaming leads to a considerable reduction in warpage and shrinkage in particular. This is good for the dimensional accuracy of the component, which accommodates numerous steering wheel functions such as switches for the turn signals and the windshield wipers, and thus features a highly complex geometry. As Helbich said, “The high dimensional accuracy ensures that the switches work reliably throughout the car’s entire life and can be operated smoothly.” A further benefit of the foaming process is the discernibly lower cavity pressures. The component can therefore be produced on smaller injection molding machines with lower clamping forces. Compared with solid molded parts, this also leads to shorter cycle times, which ultimately paves the way for cost advantages.
Support with material selection and series launch
HPM supported Kostal in switching over materials as part of its HiAnt customer service. The services included comprehensive advice in selecting the material and the production process. In addition, processing experts from LANXESS helped to optimize the series process.
