Standard model selection
Compare size, rotation direction, motion function and the published torque range.
Engineering support
Start with your application.
Build toward the right motion.
Standard selection, custom torque and interface development for rotary dampers and hinges.
Discuss your project →A clear development process
From concept to a tested sample.
A sketch, a drawing or a sample is enough
to begin the discussion.
- 01
Define the requirement
Share the application, installation space and desired movement.
- 02
Review the engineering
Compare torque, interfaces and suitable standard or custom options.
- 03
Prepare the sample
Review prototype and component details before sample evaluation.
- 04
Test & refine
Check fit and movement in the real mechanism before approval.
Standard or custom
The simplest route
that meets the requirement.
A new mould is not always the first step. We begin by reviewing existing parts, then discuss changes only where the application calls for them.
Check standard dimensions →Torque & interface adaptation
Review special torque, shaft forms and mounting geometry. Final scope is agreed after technical review.
Custom structure & mould development
For projects beyond the standard range, discuss structure, prototype evaluation and tooling requirements.
Selection essentials
Torque follows the load
and its geometry.
Changing the centre of gravity changes the load torque acting about the hinge. It does not automatically change a damper's rated torque.
The motion also depends on opening angle, temperature, speed, friction and any spring assistance. Dimensions alone do not confirm compatibility.
Request application matching →What should I send for matching?
Moving-part weight, pivot-to-centre-of-gravity distance, installation dimensions, opening angle and target closing behaviour. Add a drawing or a short description of the mechanism.
What if the centre of gravity is unknown?
For an initial estimate on a roughly uniform lid, 50% of its depth can be a starting assumption. Reinforcement, motors or uneven geometry can shift it; confirm the actual value before final selection.
Do a toilet lid and seat ring use the same damper?
Assess the lid and seat ring separately: their masses, centres of gravity and movement requirements can differ. Then review the complete hinge assembly.
Are holding and soft closing interchangeable?
No. Position-holding and slow-closing are different functions. Confirm the required movement and the model's intended function before comparing torque values.
