TECHNOLOGY

LEECO has been making substantial investment in position control technology and production capability continuously. Through extensive researches and accumulation of valuable knowledges while working closely with our customers, LEECO has developed our state of art torque engine technology to deliver cost effective and high performance constant torque hinge products. With our innovative and unique constant torque hinge technology and in-house process controls, in certain design, LEECO is able to achieve an operating cycle life of 100,000 cycles without compromising the performance.
  • Consistent torque performances over 100,000 cycles (optional)
  • Very small difference between static and dynamic torque differences
  • Easily tailored for various design requirement, especially when space is constrained
  • Negligible spring back and no backlash
  • Available in both symmetric and asymmetric torque specifications
  • Automation assembly provides quality consistency and cost effective solutions
  • All our constant torque hinges are RoHs and REACH compliant
LEECO offers many approaches in terms of constant torque hinges design. The technologies we use to generate the torque include spring clips, washer band (or friction disk), question mark band, roll pin and barrel constant torque hinge types. Each type has its advantage and trade-offs. LEECO provides solutions that optimize the performance while keep the cost competitive.

In addition to constant torque and long operation life, LEECO delivers features that are specifically stipulated by customers’ applications requirement, including
  • Detent constant torque hinges, and snap open/snap close hinges
  • Damping constant torque hinges
  • Symmetric counterbalanceed constant torque hinges
  • Asymmetric counterbalanceed constant torque hinges
  • Thin geometry constant torque hinges(less than 15mm)
  • Multiple axis constant torque hinges
  • Hollow rotating shaft for wiring
  • Different combination of above features and more. Please feel free to contact us for your constant torque hinge applications.
