Product Overview
A mini USB rubber plug can be custom molded for a device where the unused interface needs a removable closure. The connector profile and recess depth should be defined together. A plug that reaches the correct seat still needs an exposed area that remains practical to grip.
Check the space around the opening after neighboring cables or accessories are fitted. The handling feature should not disappear inside the recess or become trapped beside another connector. The silicone section should follow the intended insertion path without being folded against the case edge.
Fit the plug cleanly and in the correct orientation, using controlled pressure rather than forcing resistance. When access is needed, use the designed gripping area instead of a pointed tool inside the port. During care, inspect the small transitions for tears and keep the removed part away from contamination. Replace with the matching mini USB and enclosure profile so that both the closed position and removal access remain as intended.
- Material options
- Custom silicone compound; formulation and geometry developed together.
- Hardness selection
- Silicone options: 20–80 Shore A. The silicone section should follow the intended insertion path without being folded against the case edge.
- Custom geometry
- The connector profile and recess depth should be defined together.
- Fit evaluation
- Check the space around the opening after neighboring cables or accessories are fitted.
- Color & OEM
- Custom colors; identification clear of connectors and removal features.

Ordering this custom component
Can the shape be adjusted to my mating parts?
Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.
Which details should be agreed before tooling?
Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.
Can a sample help define the replacement?
A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.
How is the quotation for this part determined?
The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
