Tengye | Custom Molded Foam Silicone Seals Custom molded foam silicone seals (foamed silicone gaskets / sponge silicone sealing rings) are compression-molded, one-piece elastomeric foam parts engineered for reliable sealing, cushioning and thermal insulation. Produced in our strong factory with premium raw materials, each custom molded foam silicone seal is formed to your exact drawing, delivering precise dimensions and consistent foam density for demanding industrial applications.
We are a professional silicone & rubber manufacturer with an in-house mold workshop. All custom molded foam silicone seals are produced with high-grade silicone compounds and controlled foaming formulations, with no reliance on branded raw material suppliers. Strict incoming material inspection ensures stable quality, giving every batch excellent and consistent performance.
Custom molded foam silicone seals are manufactured via precision compression molding. The complete production flow includes: compound mixing → foaming formulation adjustment → preforming → precision mold loading → high-temperature molding → post-curing → deflashing → dimensional inspection → appearance sorting → packaging. This process creates uniform closed-cell foam structure with clean edges, avoiding seam leakage risks of die-cut seals and supporting complex 3D shapes and tight tolerances.
✅ Uniform closed-cell structure: dustproof, waterproof, shock-absorbing
✅ Excellent compression resilience with low compression set
✅ Soft, flexible, good thermal insulation and anti-vibration performance
✅ Resistant to UV, ozone and aging under harsh environments
✅ Working temperature range: -40°C to +220°C, stable under cold-hot cycling
✅ RoHS compliant, low odor, safe for indoor equipment
Custom molded foam silicone seals are widely used in electronics, lighting fixtures, automotive components, power cabinets, household appliances, new-energy equipment and industrial machinery. They perform reliably in outdoor exposure, high-heat enclosures, humid and dusty workshops, acting as sealing, cushioning and thermal barriers between mating parts to extend equipment service life.
We support custom production according to your drawings or physical samples, accepting OEM and ODM orders.
