Custom Custom Molded Rubber Parts Manufacturing

Julong Rubber manufactures custom molded rubber parts for OEM buyers, equipment manufacturers, industrial distributors, and engineering teams. We produce rubber components based on drawings, samples, 3D files, or specific application requirements, with support for material selection, mold development, sampling, mass production, inspection, and export packaging.

Custom molded rubber parts can be made from EPDM, NBR, silicone, FKM, HNBR, CR, natural rubber, SBR, polyurethane, sponge rubber, and other elastomer compounds. Products can be designed for sealing, cushioning, vibration damping, insulation, protection, fluid control, grip, impact resistance, and long-term industrial use.

We support compression molding, transfer molding, injection molding, rubber-to-metal bonding, secondary processing, and custom surface finishes. Buyers can specify hardness, tolerance, color, temperature range, oil resistance, weather resistance, chemical resistance, compliance requirements, and packaging needs.
