Sensor regulations spell boon for engineering plastics


European Union (EU) regulations requiring the installation of pressures sensors in car tires starting 2013 will create a market for “millions and millions” of tiny sensors relying on engineering plastics for their fabrication.

This according to Chris Schroder, Innovation Program Manager, Stanyl Product Lines, at Singapore-headquartered engineering plastics supplier’s DSM Engineering Plastics Shanghai office, who was speaking at the 4th International Conference for South & Southeast Asia: Injection Moulding, Tooling and Design, organized by Chatsworth Associates and held in Singapore September 20–21.

DSM’s laser direct structuring (LDS) technology coupled with its platable Stanyl for Tii LDS polyamide (PA) resin grades will play a key role in manufacturing the sensors, measuring just 2.5 x 3.7 x 1 mm in their final form. The PA resin is used to mold the main part of the sensors, whose surface is then activated by LDS in order to form the circuit patterns through plating. The final step is laser cutting into individual sensors.
