Tech-Key Rubber Co., Ltd. specializes in advanced silicone overmolding on metal, combining rigid metal components with flexible silicone materials to create customized products with functional structures and distinctive visual designs.
Our Silicone Overmolding on Metal with Raised Multi-Color Lettering demonstrates a more advanced application of silicone-over-metal manufacturing. In addition to integrating silicone with a metal component, the product incorporates a 3D curved silicone surface with raised, contrasting-color lettering.
This technology provides product designers with greater freedom to integrate structure, color, branding, tactile features, and three-dimensional surface design into a single component.
With more than 60 years of rubber and silicone manufacturing experience in Taiwan, Tech-Key Rubber supports customized OEM and ODM projects involving silicone-covered metal, multi-color silicone molding, curved surface designs, micro injection, and other specialized silicone manufacturing technologies. The company's current website specifically identifies multi-color silicone, curved surfaces and micro injection among its core technologies.
Silicone overmolding on metal combines a rigid metal component or insert with a molded silicone portion.
The two materials perform different functions within the finished product.
Metal provides structural support and rigidity, while silicone provides flexibility and design freedom for the exterior surface.
Depending on the product design, silicone can be molded around selected areas of the metal component to create handles, protective sections, gripping surfaces, decorative elements, branded areas, or other customized structures.
This multi-material approach allows designers to create components that would be difficult to achieve using metal or silicone alone.
The most important feature of this product is its raised multi-color silicone lettering.
Instead of printing letters onto the surface after molding, the product can be designed with three-dimensional lettering or logo features as part of the silicone structure, subject to the selected manufacturing process and project requirements.
The raised lettering creates both a visual and tactile effect.
For example, the product shown here combines a green silicone body with contrasting white raised lettering. The lettering stands above the main silicone surface, creating stronger visibility and a distinctive three-dimensional appearance.
This type of design can be considered for:
For OEM products where visual identity is important, raised multi-color lettering can turn an ordinary functional component into a more recognizable branded product.
Producing raised lettering becomes more challenging when the lettering is located on a curved three-dimensional surface.
On a conventional flat surface, positioning a logo or letter is relatively straightforward.
A curved surface introduces additional considerations.
The mold structure, product geometry, silicone flow, lettering position, feature depth, color boundaries, surface contour, and demolding conditions must all be considered during product development.
This is where Tech-Key's combination of curved surface molding and multi-color silicone technology becomes particularly relevant.
Instead of limiting the design to a flat label area, customers can explore logos, lettering, symbols, and color elements that follow the geometry of the product itself.
Color plays an important role in modern product design.
Different colors can help communicate a brand identity, distinguish functional areas, improve recognition, or simply make a product more visually attractive.
With customized multi-color silicone manufacturing, customers can explore combinations such as:
Green + White
Black + Yellow
Black + White
Blue + White
Brand-Specific Color Combinations
Actual color selection and manufacturing feasibility should be evaluated according to the silicone material, product geometry, tooling, and project requirements.
The goal is not simply to make a product colorful.
The greater value is the ability to integrate color directly into the three-dimensional product design.
This product demonstrates three manufacturing concepts working together:
The metal portion provides the structural foundation or mechanical function required by the product.
Silicone is integrated with the metal component to create the required outer geometry and functional surface.
Contrasting-color silicone lettering or graphics add a three-dimensional visual and tactile feature.
The result is a customized component that combines:
Structure + Flexibility + Color + Branding + 3D Surface Design
This combination makes the technology particularly interesting for OEM customers developing products where both functionality and appearance matter.
Customers can provide 2D drawings, 3D files, existing samples, or product concepts.
Our team evaluates the metal structure, silicone-covered area, curved surface, lettering, color requirements, dimensions, and application.
The metal component is reviewed according to its geometry, dimensions, interface with the silicone, and intended function.
Silicone characteristics and colors are evaluated according to product requirements.
For multi-color designs, the position and relationship between different colors must also be considered.
The mold must accommodate not only the metal component and main silicone body but also the required three-dimensional surface features.
Raised letters, logos, or symbols require appropriate tooling design to reproduce their geometry.
The metal and silicone components are integrated according to the validated manufacturing process.
The contrasting lettering or design features are produced according to the approved product structure and manufacturing method.
Finished components are inspected according to agreed specifications before packaging and shipment.
Raised logos and customized colors can be used for electronic accessories, portable products, protective components, and branded device accessories.
Silicone-overmolded metal components can be evaluated for customized control parts, accessories, handles, protective components, and identification features.
Industrial components may use different colors, raised markings, letters, or symbols to support product identification and functional design.
The combination of metal, soft silicone, and raised branding is particularly suitable for products such as zipper pulls, tags, accessories, and customized fashion components.
Multi-color silicone can create distinctive visual designs for sports accessories and lifestyle products.
Raised logos and letters provide an alternative to conventional surface printing when a customer wants branding to become a physical part of the product design.
Printing and molded lettering serve different design purposes.
Printing is useful when a relatively flat graphic is required. However, when the product concept calls for a stronger tactile effect or a three-dimensional appearance, raised molded lettering provides another option.
Raised silicone lettering can create:
The appropriate solution should always be selected according to product design, quantity, material, performance, and manufacturing requirements.
