Overmolded components: Low pressure, high performance

Our thermoplastics help you design and manufacture overmolded components and sensors more efficiently. Specifically our Stanyl® polyamide 46 can replace traditional machined-metal, multi-part, automotive sensor components like transmission speed sensors and oil level sensors.

Overmolded components like solenoids and sensors need high-temperature resistant materials that can be processed at low pressure and thus avoid displacement of the electronic components.

Stanyl is also increasingly used for sensors because of its excellent creep resistance and ability to withstand temperatures of 150 to 160°C for up to 5,000 hours – with a peak temperature of up to 180°C (while also withstanding aggressive ATF oils).

This strong material also meets a wide range of requirements specific to sensors, including temperature cycle tests, vibration tests at various temperatures, and severe long-term tests for the ability to maintain a good seal against ingress of air, oil, dust, and water at elevated pressures and temperatures.

In fact Stanyl not only provides excellent dimensional stability for overmolded part true position but it also offers cost reductions through the ability to consolidate parts.

Major OEMs choose Stanyl for sensors

Stanyl has been chosen by several leading automotive OEMS for metal replacement in sensors because of its ability to consolidate multiple metal components into a single injection-molded part, in turn reducing system costs.

And we do far more than simply provide the material. We are closely involved in designing these parts: For example, we use Finite Element Analysis to simulate torque loads – as well as working with the customer from prototyping through to full-scale production.

Stanyl TW200F6 provides more cost effective and better processing than PPS while delivering temperature resistance up to 180°C for oil level sensors.
