Custom silicone molding
Compression and transfer molding of custom silicone parts. Geometry, hardness, colour, surface finish and molded details are developed around your product requirements.
What this capability produces
Is it a good fit
Typical situations where custom molding is the right approach.
Non-Standard Shapes
You need a custom shape that does not exist as a standard product.
Fit To Existing Products
The silicone part must fit an existing product or interface.

Frequently asked questions
Can you develop a silicone product from a drawing?
Yes. Projects can start from 2D drawings, 3D / CAD files or confirmed dimensions; geometry and moldability are reviewed before tooling.
Can I send a physical sample instead of a CAD file?
Yes. A physical sample is a preferred starting point; dimensions and interfaces are confirmed from the sample.
How do you select silicone hardness?
Hardness is selected according to product function, flexibility, surface feel and environment, then confirmed on samples.
Can Pantone colors be matched?
Yes. Color matching is based on confirmed Pantone references and checked during sampling.
Can logos and surface textures be molded into the product?
Yes. Logos, textures, ribs and channels can be built into the mold geometry and confirmed on first samples.
Do you support multi-color silicone molding?
Yes. Multi-color molding is reviewed with the design, color separation and structure before tooling.
Can molded silicone parts be assembled with plastic or metal components?
Yes. Silicone can be overmolded onto or assembled with plastic and metal components; interfaces are reviewed at the design stage.
What information is needed for quotation?
Drawings, CAD files or samples, application and fit requirements, material and hardness targets, quantities and packaging expectations.
