Explore our top-performing custom engineered profiles, O-rings, and EPDM extrusion systems built for rigorous industrial applications.
Modern engineering relies heavily on sealing technologies that can withstand structural stresses, thermal variations, dynamic vibration, and exposure to environmental stressors. As a leading hub for global elastomer production, Chinese manufacturers deliver state-of-the-art liquid sealing gasket solutions alongside traditional extruded profiles like EPDM sponge, NBR, and silicone strips.
Whether for electric vehicle battery enclosures, automated heavy-duty machinery, architectural glass curtain walls, or delicate micro-electronics, selecting the correct chemical compound and gasket form factor determines the product's ultimate lifecycle performance. Today's global supply chain expects more than just material supply; it demands high precision tooling, customized elastomer blending, and comprehensive regulatory compliance from a single manufacturer.
By integrating raw material prep, rapid mold design, co-extrusion engineering, and advanced testing under one roof, companies like Zhejiang Haala Automotive Parts Co., Ltd. set the standard for high-performance sealing solutions globally.
How localized manufacturing clusters in Hebei and Zhejiang optimize production costs, engineering speeds, and delivery timelines for global buyers.
Our proximity to world-class petrochemical refining networks allows for rapid custom compounding of premium EPDM, NBR, FKM, and silicone polymers. This ensures zero downtime and steady prices even during volatile raw material cycles.
We host complete, localized tooling shops that reduce custom die development from the industry standard of 6 weeks down to under 10 days. Our engineers rapidly execute CAD/CAM adjustments directly inside the extrusion workflow.
Located in the heart of China's automotive parts production zones, our logistics hubs offer streamlined customs clearance and direct sea/air shipping pipelines via Qingdao, Ningbo, and Shanghai ports, minimizing transit times.
Delivering top-tier industrial weatherstripping and custom-molded elastomeric parts for global buyers.
Selecting the right compound guarantees long-term sealing integrity. Here's a structural breakdown of the principal materials used in our industrial production line.
EPDM is the premier choice for outdoor, automotive, and architectural applications due to its excellent resistance to ozone, UV radiation, weathering, and heat aging. It performs robustly between temperatures of -40°C to +130°C. EPDM sponge or dense E-type, P-type, and D-type profiles are critical for weatherproofing automotive door panels, window frames, and electric utility cabinets.
NBR is highly resistant to petroleum oils, minerals, and vegetable oils, making it the industry standard for engine seals, hydraulic lines, and O-ring gaskets. With high tensile strength and wear resistance, our customized NBR O-Rings (ranging from 1.6mm ID up to 150mm ID) are essential parts for high-pressure fluid power applications.
For extreme temperature profiles ranging from -60°C to +250°C, silicone strip and gasket solutions offer unparalleled stability. Silicone is widely utilized in medical equipment, food processing (FDA-compliant compounds), and aerospace applications, providing excellent compression set resistance and electrical insulation properties.
We configure rubber compounds to match precise physical and chemical specifications:
Navigating complex international standards is critical. We ensure that our materials meet global chemical safety and mechanical performance regulations.
We work closely with global automotive OEMs and industrial product developers who require complete traceability. Our manufacturing processes and products align with the following regulatory frameworks:
Through robust testing routines (tensile testing, ozone exposure chambers, compression set fixtures, and dimensional optical sorting), we guarantee that every batch of automotive seals, decorative strips, or custom gaskets is defect-free.
The industrial seal market is evolving. Our R&D team continuously adapts to meet next-generation industrial demands.
Modern assembly lines are transitioning from pre-cut rubber seals to automated Form-in-Place (FIPG) and Cured-in-Place (CIPG) liquid sealing systems. We formulate specialized liquid silicones and polyurethanes that can be applied directly via automated robotic arms, minimizing material waste and speeding up manufacturing.
Electric vehicles require light, heat-resistant, and flame-retardant sealing solutions to safeguard battery modules from dust and moisture ingress (IP67/IP68). We supply multi-component co-extruded EPDM sponge profiles paired with high-performance adhesive layers to meet dynamic thermal expansion requirements.
Sustainability is driving material changes. Our production lines feature high-grade TPE and TPV co-extrusion technology. TPE/TPV seals offer excellent elasticity, are 100% recyclable, and allow for easier coloring and styling compared to vulcanized thermoset rubbers.
We combine engineering expertise, vertically integrated production, and global delivery networks to deliver premium industrial solutions.
Our facility runs multiple EPDM co-extrusion and rubber molding lines, producing custom vehicle, window, air conditioning, and electrical cabinet seal strips built to specification.
From raw material prep and mold development to final part molding and dynamic testing, our integrated quality systems ensure high performance and dimensional accuracy.
Our products are shipped worldwide to customers in Japan, Germany, the United States, France, Iran, Australia, Türkiye, India, Nigeria, Brazil, and Russia.
