Torque Hinges for Medical, Automation & Panels

Torque hinges are friction hinges that hold panels, lids, and displays in any open position through calibrated friction resistance — available in constant torque (factory-preset) and adjustable torque variants from 0.3 Nm to 50+ Nm. HTAN’s torque hinge range is manufactured with ISO 9001-certified quality and full OEM/ODM customization for global customers.

Key Features

Constant torque: Factory preset, production-consistent, no field adjustment — ideal for high-volume OEM assembly.
Adjustable torque: Field-tunable via set screw — for variable load applications or wear compensation over time.
Wide torque range: Models from 0.3 Nm for miniature electronics to 50+ Nm for industrial panels.
Material options: Stainless steel, zinc alloy, and engineering polymer variants.

Key Applications

Laptop & Tablet Displays: Screen positioning hinges requiring uniform torque across mass-production volumes.
Medical Device Lids: Fixed-angle display positioning on portable diagnostic equipment.
Industrial Panel Arms: HMI screens and operator displays on machinery and control consoles.

Frequently Asked Questions

Can HTAN manufacture torque hinges to a specific Nm value?

Yes. OEM torque specification is a standard service. Provide your required torque value, panel weight, and operating temperature range and we will confirm feasibility.

How long do torque hinges maintain their specified friction value?

HTAN torque hinges are tested for long-term torque retention across defined cycle counts. Torque retention data is available on request for specification-critical applications.

What is the difference between constant and adjustable torque hinges?

Constant torque hinges are factory-set with no field adjustment — best for OEM mass production requiring identical units. Adjustable torque hinges allow on-site tuning via a set screw — best for field-installed or maintenance-accessible applications.
