Import Custom Extruded Seal — Buy in Bulk from Supplier in China

These custom extruded seals are produced from silicone rubber, extruded to precise cross-sectional profiles based on customer drawings or physical samples. The material exhibits a Shore A hardness range of 30 to 70, allowing for flexibility in compression set and sealing force requirements. The seals are manufactured without plasticizers or halogenated additives, ensuring compliance with RoHS and REACH for industrial applications.

Silicone is the primary material, chosen for its thermal stability between -50°C and +200°C, resistance to UV degradation, and low gas permeability. Alternative materials such as EPDM or nitrile are available upon request for applications requiring oil resistance or lower cost. The extrusion process maintains dimensional tolerances of ±0.1 mm for profiles under 10 mm wide, and ±0.2 mm for wider sections, consistent with ISO 3601-1 standards for rubber seals.

These seals are purchased by OEMs in automotive, aerospace, and industrial machinery sectors for use in engine gaskets, door seals, and hydraulic systems. Orders are typically placed in minimum quantities of 100 meters per profile, with lead times of 14 to 21 days for new tooling. Packaging is in coiled lengths of 50 to 100 meters, wrapped in polyethylene and boxed in moisture-resistant cartons. Incoterms offered include FOB Qingdao and CIF, with payment via T/T or L/C.
