Molded Rubber Sealing Gasket is manufactured by compression molding of elastomer compounds under heat and pressure. Different from simple die-cut gaskets, molded gaskets can realize complex 3D profiles, holes, grooves and special shapes. It blocks liquid, gas and dust leakage, and also provides vibration buffering. Multiple rubber materials are optional to match different temperature, pressure and media conditions. We support custom molding according to your 2D/3D drawings or physical samples for static and dynamic industrial sealing.

1. What is a molded rubber sealing gasket?
It is a rubber gasket formed by compression molding under heat and pressure. It can make complex shapes, different from simple die-cut gaskets, used to prevent leakage of gas, liquid and dust.
2. What rubber materials can you supply?
We offer NBR, HNBR, FKM/Viton, EPDM, Silicone(VMQ), Neoprene(CR), FFKM, SBR and natural rubber. You can select based on temperature, medium and working condition.
3. What is the difference between molded gasket and die-cut gasket?
Molded gasket: complex 3D profiles, multi-hole, special cross-section, stable tolerance, for high-performance sealing.-cut gasket: simple flat shape, low cost, made from rubber sheet.
4. Can you customize the shape and size?
Yes. We support custom molding according to your 2D/3D drawings or physical samples. Hardness from 30 to 90 Shore A is available.
5. What temperature range can molded rubber gaskets withstand?
It depends on the rubber compound. EPDM & NBR: -40~120℃; HNBR: -40~150℃; FKM: -20~200℃; Silicone: -60~220℃.
6. Are molded gaskets for static sealing only?
No. Suitable for both static sealing and dynamic sealing, subject to proper material selection.
7. What certifications are available?
ISO9001, RoHS, REACH are standard. FDA, NACE MR0175, NORSOK M710 grades can be supplied upon request.
8. What information do I need to provide for quotation?
Drawings or samples, material, hardness, working temperature, contact media, quantity and special certification requirements.
9. What is your MOQ?
Small MOQ is acceptable for sample prototypes. Mass production MOQ depends on mold structure and part size.
