Protective covers
Custom Silicone Protective Covers & Sleeves
WYD manufactures custom silicone protective covers, sleeves and boots for electronic devices, equipment, handles and other OEM products.
A protective cover should be developed around the real device geometry. Overall length and width alone are rarely enough to control fit.
What We Need From the Device
For accurate fit, provide:
- device/housing 3D file
- physical sample if available
- port openings
- buttons
- camera/sensor locations
- vents
- mating features
- areas that cannot be covered
- installation direction
For reverse-engineering projects, a real device sample is often more reliable than dimensions copied from a public website.
DFM for Silicone Covers
Interference and Retention
The cover must grip the housing enough to stay in place without becoming difficult to install.
Wall Thickness
Thin walls improve flexibility but can roll, tear or reveal underlying geometry.
Edge Lips
Retention lips and openings need enough strength to recover after installation.
Button Feel
Silicone thickness over a button can change actuation feel.
Port and Camera Clearance
Openings should be checked on the assembled device, not only in isolated CAD.
Parting Lines
Seams and flash should avoid critical mating/cosmetic areas where possible.
Manufacturing Routes
HCR/HTV Compression Molding
A common process for custom silicone covers and sleeves.
LSR Injection Molding
Can be used for designs and volumes suited to LSR.
Overmolding
If the silicone is permanently integrated with a rigid housing/insert rather than removable.
RTV Mold Making
WYD also offers RTV silicone molds where the purchased item is a casting mold. This is separate from manufacturing the finished protective cover.
Environmental Requirements
Tell us what the cover will experience:
- repeated installation/removal
- outdoor UV
- sweat/skin contact
- cleaners
- water
- oil/chemicals
- temperature
- drop/impact conditions
Do not claim IP, waterproofing or chemical resistance based on the silicone cover alone. Those functions depend on the complete device assembly and must be tested accordingly.
Prototype Validation
Check the sample on the real device for:
- fit
- retention
- install/remove force
- lip rolling
- button feel
- port/camera alignment
- surface grip
- recovery after removal
- cosmetic marks
- repeated cycles
What to Send for a Quote
- device CAD or sample
- desired cover geometry
- Shore hardness
- color/finish
- logo
- environment
- target quantity
- annual volume
- packaging/assembly requirement
Request a Protective Cover Fit Review
Send the device CAD or a physical sample so we can review interference, openings and retention.
