Wabash Technologies selected Stanyl for the transmission sensor used on
heavy-duty full size and commercial trucks. Stanyl TW200F8 (40% glass
reinforced polyamide 46) is used for the main body of the sensor and Stanyl
TW271F6 (30% glass reinforced polyamide 46) is used for the rotor.
The sensor, which determines whether the transmission gear is in park,
neutral, or the various drive gears, demands high temperature transmission oil
resistance, high temperature stiffness (150°C) peaks to 170°C, and excellent
wear resistance. Polyamides are well known for their resistance to a wide
range of chemicals. Stanyl is no exception. At higher temperatures its
resistance to oils and greases is excellent. Due to its high crystallinity,
Stanyl retains a high level of stiffness up to temperatures very close to its
melting point. This provides wider safety margins for critical applications
than standard engineering plastics (e.g. PA6, PA66, and polyesters). Stanyl
has an excellent wear resistance and outperforms other engineering/high
performance plastics under most conditions but especially at higher
temperatures or high torque/loads.
DSM engineers provide OEM’s and suppliers with the technical support they need
to turn their innovations into successes delivering added value through
knowledge, performance, and confidence. The cover of the sensor and the
interface of the body needed to be flat and match up so the two parts could
fit together and be ultrasonically welded. Engineers were able to provide
design assistance, mold flow and gating recommendations for part dimensions
allowing for the successful design of this sensor.

Wabash Technologies started business in
1946 as DeLuxe Coils Inc. employing 19 people, in a 400 sq. ft. facility.
Today, they are Wabash Technologies, employing over 1,200 people and occupying
more than 220,000 sq. ft. of manufacturing space. They produce over 20 million
sensors and 5 million fuel injection stators / actuators per year. Current
operations are separated into two units: Custom Designed Products Division and
Specialty Products Division, (SPD). Wabash Technologies is celebrating its
60th year of designing and manufacturing powertrain sensors and actuators for
the automotive and commercial vehicle markets.
