A process similar to compression molding, suited for more complex geometries where material flow and controlled cavity filling are important.
A molding process suited for more complex geometries and tighter tolerances, helping support repeatable production for technical rubber parts.
Extruded rubber is available in a wide variety of shapes and lengths. Extrusions can be spooled or cut to set lengths in-line.
Our in-house chemists formulate and mix custom rubber compounds to deliver consistent processing, reliable performance and application-specific material properties. Caplugs supports a broad range of organic and silicone materials, including EPDM, NR, NBR, SBR, HNBR, CR, IR and FKM, with custom additives available for heat, UV, chemical and environmental resistance.
Every batch undergoes rigorous testing and validation to ensure quality, repeatability and long-term performance.
Our rubber molding experts work with you to determine the best solutions for your exact specification.
Our keys to success are:
Design support, DFM (Design for Manufacturability), and material selection to improve performance and reduce cost.
Compression, transfer, extrusion, and injection molding across a wide range of elastomers.
Flexible global manufacturing footprint to reduce lead times and ensure supply continuity.
Collaborate with Caplugs on part function, geometry, fit, installation needs and design-for-manufacturability.
