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. Detail limits depend on feature size, depth and location: small lettering and fine textures are confirmed on samples, and very fine detail in soft compounds may call for a harder grade or a finishing step. Provide the artwork at final size for a manufacturability review before tooling.
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.
How do platinum-cured and peroxide-cured silicone affect product requirements?
The curing system changes what you should specify, not just the material grade. Platinum-cured silicone is typically chosen where low odour, clear or light colours and long-term stability matter — food-contact, wearable and baby-adjacent products commonly take this route. Peroxide-cured systems remain cost-effective for many industrial and non-critical consumer parts, but by-products can affect odour or post-cure requirements, so parts may need additional post-baking depending on the application. The decision depends on contact media, colour, odour sensitivity and target cost. Tell us the function, contact conditions and target hardness, and we will recommend a curing route with the verification points — appearance, odour and physical properties — written into sample approval.
What do tensile strength, elongation and tear strength tell a buyer?
Tensile strength describes how much stress the material survives before breaking; elongation shows how far it stretches; tear strength shows resistance to tear propagation once a cut or nick starts. Reading one number in isolation is misleading: a soft 30 Shore A compound will never match a 60 Shore A grade on tensile, yet may still be the right choice for a grip or seal. What matters is the combination your product needs — stretch for collapsible items, tear resistance for thin walls or tabs, dimensional stability where the part carries load. Give us the function, contact media and target hardness, and we will propose compounds whose datasheet properties match the application, then confirm the actual behaviour on samples rather than on datasheets alone.
What information is needed for quotation?
Drawings, CAD files or samples, application and fit requirements, material and hardness targets, quantities and packaging expectations.
