Selected for the contact, temperature and movement
Define the visible surfaces and intended color
Develop holes, lips and walls around the mating parts
Match the attachment and installation method
Bicycle silicone grips should match the handlebar interface and the clearance around controls, while a dumbbell handle version needs its own fit to the supporting core. Both use a silicone hand contact region, but their retention and handling conditions differ. Select the grip for the actual assembly instead of transferring a size between these applications on appearance alone.
Define the core diameter, covered length, and end position. The outside shape should permit the intended hand placement without crowding a control or leaving an exposed edge where the hand naturally rests. Consider the relevant dry, damp, and cleaning conditions when assessing the finished contact.
Install with the sleeve aligned and free of twist. Verify that the grip does not rotate or slide under the forces expected in its selected use. On a bicycle assembly, check surrounding control operation after fitting. On a handle used with weights, assess retention within that complete equipment design. Inspect the ends and contact region regularly, replacing a split or loose covering rather than attempting to restore fit with uneven improvised packing.

ETOL directly manufactures custom-shaped silicone and rubber parts to your requirements.
Identify key dimensions, mating surfaces and quantity
Agree the compound and manufacturing approach
Review the fit and agreed requirements in the assembly
Manufacture and check against the approved requirements
Identify temperature, contact fluids and repeated movement.
Consider hardness together with wall thickness and support.
Check access, mating dimensions and the fitting sequence.
Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.
Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.
A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.
The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
