TECHNOLOGY

LEECO has been making substantial investments in position control technology and production capability continuously. Through extensive research and accumulation of valuable knowledge while working closely with our customers, LEECO has developed our state-of-the-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 designs, LEECO can achieve an operating cycle life of 100,000 cycles without compromising performance.

• Consistent torque performance over 100,000 cycles (optional).
• Very small difference between static and dynamic torque differences.
• Easily tailored for various design requirements, 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 advantages and trade-offs. LEECO provides solutions that optimize performance while keeping the cost competitive.

In addition to constant torque and long operation life, LEECO delivers features that are specifically stipulated by customers’ applications requirements, including

• Detent constant torque hinges, and snap open/snap close hinges.
• Damping constant torque hinges
• Symmetric counterbalanced constant torque hinges.
• Asymmetric counterbalanced constant torque hinges.
• Thin geometry constant torque hinges (less than 15mm).
• Multiple axis constant torque hinges.
• Hollow rotating shaft for wiring.
• Different combination of the above features and more.
