FAQ
What does “flat-opening design” mean for panel applications?
Both leaves lie in the same plane at full travel, so the lid opens completely flush — no offset gap. This simplifies gasket sealing on flush-mount enclosures and eliminates pinch points on operator-facing panels.
How do I choose between the 25×20 mm, 25×30 mm, and 28×40 mm sizes?
Match size to panel weight and mounting area: 25×20 mm for the lightest covers, 25×30 mm for moderate loads or thicker panels, 28×40 mm for the widest span and highest torque demand. As a rule, the leaf length should cover at least 60% of the panel edge for even load distribution.
How does free-stop positioning work, and does friction degrade?
Internal friction holds the panel at any angle without detents or snap-back. Torque does decrease gradually under heavy cycling — if drift is a concern, confirm with the supplier whether adjustable-torque or replaceable-friction variants are available before specifying.
When should I choose plastic over metal for a torque hinge?
Plastic wins where corrosion resistance, electrical insulation, or low weight matter most — humid environments, electronic enclosures, and portable equipment. For continuous temperatures above 60°C or loads beyond ~2 kg, however, a metal torque hinge is the safer long-term choice.
What product types are these hinges best suited for?
Flat-opening geometry and free-stop friction make them a practical fit for network equipment access panels, portable instrument lids, control cabinet doors, appliance covers, and medical device housings. For OEM procurement, the three-size range supports a full product family from a single supplier.
