Rubber Molding and Forming Manufacturers in the U.S.

Rubber molding and forming services are essential across industries ranging from automotive and aerospace to medical, agriculture, and heavy equipment. On RFQ USA, you can connect with qualified, certified manufacturers that specialize in the design and production of precision-molded rubber components. Whether you need high-volume production of standard parts or a supplier capable of handling custom geometries and specialty compounds, our directory makes it easy to find the right partner.

We feature a vetted group of companies offering compression molding, transfer molding, injection molding, and extrusion services tailored to your application, performance requirements, and budget.

ISO and IATF Certified Rubber Manufacturers

Many of the rubber molding companies listed on RFQ USA are ISO 9001:2015 certified, ensuring they maintain quality management systems that consistently deliver high-performing, defect-free parts. For companies in the automotive supply chain, we also highlight manufacturers that hold IATF 16949:2016 certification, demonstrating strict process control, documentation, and traceability.

For buyers with defense or aerospace contracts, RFQ USA also lists ITAR-registered and AS9100-certified rubber manufacturers that meet the elevated standards for military-grade applications.

Custom Compression, Transfer, and Injection Rubber Molding

Each project has different requirements, and RFQ USA includes manufacturers with a range of forming methods and equipment:

• Compression molding for cost-effective production of gaskets, seals, bumpers, and pads in low to mid volumes
• Transfer molding for more intricate parts with embedded components or tighter dimensional tolerances
• Injection molding for high-volume runs of complex, precision rubber parts requiring excellent consistency
• Rubber extrusion for continuous profile components like tubing, weatherstripping, and vibration dampeners

These manufacturers work with materials suited to your thermal, chemical, or environmental performance needs.

Custom Tooling, Prototyping, and Overmolding Capabilities

Many of the manufacturers listed on our platform provide custom tooling and mold design support. Whether you need rapid prototyping, mold revisions, or full production tooling, RFQ USA connects you with suppliers that understand both product performance and manufacturability.

Some companies also offer overmolding services, combining rubber with metal or plastic components to form integrated, multi-material assemblies. This is especially useful in automotive bushings, handles, vibration isolators, and medical devices.

Specialized Rubber Materials for Unique Applications

Different projects require different rubber compounds, and our listed manufacturers are capable of working with a wide range of materials to meet your unique demands. These include:

• FKM (Viton), which offers outstanding resistance to heat, chemicals, fuels, and oil, making it ideal for aerospace, chemical processing, and automotive environments
• SBR (styrene-butadiene rubber), a cost-effective material commonly used for general-purpose seals, gaskets, and shock-absorbing parts due to its flexibility and abrasion resistance
• NBR (nitrile butadiene rubber), known for excellent oil resistance, making it a top choice in fuel systems, hydraulic hoses, and seals
• EPDM, used extensively in outdoor applications for its weather, ozone, and UV resistance
• Neoprene, valued for its balance of durability, flexibility, and chemical resistance
• Silicone, often used in medical and food-grade applications due to its biocompatibility and performance at extreme temperatures
• Natural rubber, preferred for high-strength parts with superior elasticity

Manufacturers on RFQ USA are ready to assist with material selection to match your project’s durability, compliance, and cost expectations.

FDA-Grade, USP Class VI, and Cleanroom Rubber Parts

For food processing, pharmaceutical, and life science applications, our platform includes companies capable of producing FDA-compliant and USP Class VI rubber parts. Some members maintain ISO Class 7 or Class 8 cleanrooms for molding silicone and other specialty elastomers in contamination-sensitive environments.

Whether you’re sourcing medical tubing, fluid transfer components, or food-grade rubber seals, you can filter your results by regulatory compliance and certifications.
