Custom Profile Extruded Seals

Custom profile extruded seals are engineered sealing solutions tailored to meet unique and specific application requirements that standard, off-the-shelf profiles cannot address. By pushing elastomeric material through a custom-designed die, manufacturers can create precise shapes that optimize sealing performance for complex geometries and demanding environments.
Key Features and Benefits
Bespoke Design: The primary advantage is the ability to design a seal with the exact cross-section needed to accommodate unique gap dimensions, multiple sealing points, or complex edge profiles.
Optimized Performance: Custom profiles allow for precise control over material placement and wall thickness, ensuring optimal compression, resilience, and sealing effectiveness for the intended application.
Problem Solving: They are ideal for solving challenging sealing problems involving complex mating surfaces, extreme environmental conditions, or multi-function requirements (e.g., sealing, noise reduction, and edge protection simultaneously).
Material Versatility: Custom profiles can be produced from a wide array of elastomers (EPDM, Silicone, NBR, FKM, Neoprene, etc.), ensuring compatibility with the operating environment's temperature, chemical exposure, and physical demands.
Cost-Effective for Volume: While initial tooling costs are incurred, custom extrusion becomes cost-effective for medium-to-high volume production, avoiding the high cost of custom-molded parts.
Common Materials
The choice of material is tailored to the specific application's environmental needs:
EPDM (Ethylene Propylene Diene Monomer): Excellent for outdoor weatherability, UV, ozone, and water resistance (e.g., weatherstripping for custom vehicle bodies).
Silicone Rubber: Ideal for extreme high/low temperatures, medical, and food-grade applications (e.g., seals for specialized industrial ovens or cryogenic equipment).
Nitrile (NBR / Buna-N): The best choice for resistance to oils, fuels, and solvents (e.g., seals for custom industrial fluid systems).
Viton® (FKM): Used for harsh chemical environments and very high temperatures (e.g., seals for specialized chemical processing equipment).
Applications
Custom profile seals are used across diverse industries where standard solutions are insufficient:
Automotive and Transportation: For unique vehicle body seals, window channels, and engine bay seals in specialty vehicles or mass transit systems.
Architectural and Construction: In custom window frames, curtain wall systems, and unique structural joints for weatherproofing and insulation.
Industrial Machinery and Enclosures: Sealing complex access panels, specialized equipment guards, and cleanroom equipment where off-the-shelf seals fail to provide a perfect fit.
Aerospace and Marine: For critical sealing applications in aircraft or boat hatches where stringent performance and precise fitting are required.
