Custom Silicone Power Back Cover - China Suppliers & Factory for Durable Overmolding Solutions
Discover our high-quality covers engineered using advanced LSR (Liquid Silicone Rubber) overmolding technology, proudly manufactured in China. As a leading factory and supplier, we create a strong, seamless bond between silicone and plastic substrates, ensuring superior waterproof protection. This innovative construction safeguards internal hardware from moisture, sweat, and environmental exposure, making our products ideal for various applications. The durable silicone outer layer not only provides an impressive shield against impacts and daily wear but also delivers long-lasting performance with a premium ergonomic finish. We custom design covers precisely to your technical drawings and specifications, making us your go-to supplier for high-performance solutions
What truly distinguishes us is our commitment to making your unique product vision a reality. We understand that every power bank has its own specific dimensions, contours, and functional requirements—from precise cutouts for USB ports and LED indicators to exact button placements and thickness specifications.
Simply provide us with your 2D engineering drawings, 3D files (STEP/IGES/STP), or physical reference samples, and our experienced engineering team will handle the rest. From complex geometries with integrated button features to precise wall thickness requirements for optimal protection, we can create a silicone cover that integrates perfectly with your existing power bank housing.
This OEM/ODM service ensures your power bank products achieve the exact fit, feel, and protective performance your brand and customers demand—qualities that standard, off-the-shelf covers simply cannot provide.

Frequently Asked Questions
Q
What file formats do you accept for custom power bank cover orders?
We accept 2D engineering drawings (PDF, DWG, DXF), 3D CAD files (STEP, IGES, STP), and physical reference samples. Our engineering team will review your files and confirm feasibility before proceeding with tooling.
Q
What is the minimum order quantity (MOQ) for custom silicone power bank covers?
Our standard MOQ is 1,000 pieces per design. This applies to both new custom designs and repeat orders. Please contact us to discuss your specific requirements if your volume differs.
Q
How long does it take to produce a custom silicone power bank cover from scratch?
Tooling (mold fabrication) typically takes 15–20 working days. Once the mold is approved, mass production requires an additional 25–35 working days. Total lead time from order confirmation to shipment is generally 40–55 working days.
Q
Can you match our exact brand color for the silicone covers?
Yes. We offer Pantone color matching services. Simply provide your Pantone code or a physical color swatch, and our team will formulate the silicone compound to achieve the closest possible match for your brand's requirements.
Q
What certifications does your silicone material comply with?
Our Liquid Silicone Rubber (LSR) materials are available with FDA, LFGB, RoHS, and REACH compliance certifications upon request. Please specify your target market and regulatory requirements when placing your order so we can provide the appropriate documentation.
Q
Can you add our logo or branding directly onto the silicone cover?
Absolutely. We offer multiple branding integration methods including embossing (raised logo), debossing (recessed logo), and laser etching directly onto the silicone surface. These can be incorporated into the mold design at no extra cost for standard applications.
