Custom molded rubber parts are uniquely designed rubber components tailored to meet specific shapes, dimensions, and performance requirements. They are widely used across industries such as automotive, medical, aerospace, marine, electronics, and industrial machinery, where standard parts do not meet the functional or assembly demands.
At okinrubber, we specialize in precision custom rubber molding using a variety of high-performance elastomers. Our team offers design support, prototyping, and scalable production to help bring your concept to reality. Whether you need high-precision seals, complex rubber-to-metal bonded parts, or multi-cavity molded parts, we have the experience and capability to deliver.

Custom molded parts are produced through compression, transfer, or injection molding processes, depending on part complexity, material, and production volume. We work closely with clients to choose the right method and ensure material compatibility, tight tolerances, and cost-efficiency.
Standard rubber parts may not fit specialized designs or harsh operating conditions. Custom rubber molding allows precise dimensional control, optimized performance, and material selection based on actual working environments. It enhances product reliability and overall efficiency.
