Delivering high-performance gears for compact electric engine actuators

Automotive brands are under pressure to comply with vehicle emission regulations. More OEMs are leveraging electric engine actuators that improve fuel efficiency. Yet, finding material solutions ideal for producing thin and reliable actuator gears is a challenge. 

OEMs require actuators that are highly durable, and sufficiently compact to fit in the vehicle’s engine bay. For engine actuator suppliers, this means developing parts using material solutions that respond to customers’ design and performance requirements. A key challenge to meeting these needs is finding a material suitable for producing small-sized gears that fit into compact actuator designs and operate well in high-temperature under-the-hood conditions.

Understand why Stanyl® PA46 is a proven automotive actuator solution

Polyphthalamides (PPA) and PA66 traditionally used to manufacture gears aren’t often durable enough for compact actuator gears. While additional design effort can strengthen the material, these processes are expensive and result in bulky gears. 

Stanyl® PA46, an industry-leading high-temperature aliphatic polyamide, has been used in the automotive industry for over 20 years and offers: 

  • Best-in-class thermal, creep and fatigue resistance 
  • Outstanding durability in high torque applications
  • Excellent mechanical performance preventing gear failure
  • Inherent wear and friction properties eliminating the need for material enhancing additives
  • Superior flow properties enhancing design flexibility
  • Up to 40% less material required for molding gears
