In the modern industrial landscape, a sealing strip is no longer just a barrier against moisture; it is a critical component of Kinetic Energy Dissipation (KED). Collision-resistant sealing strips are engineered to absorb impact forces, protecting sensitive automotive electronics, heavy machinery chassis, and architectural structural integrity. As a leading factory, we focus on the "Information Gain" of material science, moving beyond standard EPDM to multi-composite structures.
Our R&D focuses on the transition from traditional PVC to TPV (Thermoplastic Vulcanizates) and high-resilience Silicone. This roadmap ensures that our strips maintain a "Compression Set" of less than 15% after 100,000 cycles, offering unprecedented longevity in extreme environments (-60°C to +250°C).
We utilize triple-extrusion lines that combine a dense rubber core for structural attachment, a sponge rubber bulb for sealing, and a low-friction coating (flocking or PTFE) to prevent "freezing" or "sticking" in automotive glass run channels.
The next generation of collision strips will incorporate conductive elastomers or embedded sensors. These "Smart Seals" can detect seal breach or excessive impact in logistics containers, providing real-time data to fleet managers.
Zhejiang Haala Automotive Parts Co., Ltd. is a medium-sized private enterprise mainly engaged in the production of various types of vehicle sealing strips, integrating scientific research, development, production, and sales. With nearly ten years of professional production experience, we have established ourselves as an industry benchmark in the Matun Industrial Zone.
Our specialization spans across automotive sealing strips, door and window sealing strips, air conditioning sealing strips, furniture sealing strips, electrical sealing strips, foam sealing strips, and mechanical sealing strips.
We have equipment such as EPDM production lines, rubber molding production lines, flat vulcanization machines, and extruders. Our complete testing methods form a one-stop production model of raw material preparation, mold development, and product molding. This integration reduces lead times by 30% compared to fragmented suppliers.
Our products are sold to Japan, Germany, the United States, France, Iran, Australia, Türkiye, India, Nigeria, Brazil, Russia and other countries. This global footprint is built on our adherence to "Reputation First," providing products that meet the stringent VDA 6.3 German automotive standards and ASTM D2000 American standards.
The company has strong technical strength and management experience. We continuously strengthen the quality awareness of employees, introducing AI-driven visual inspection equipment to ensure zero-defect output for collision-critical components.
For brands like Shacman (X3000), our strips offer two-way sealing that resists vibration-induced wear. Ideal for long-haul transport where cabin pressure and noise reduction are paramount for driver safety.
EPDM sponge (foam) sealing strips and building rubber sealing strips are utilized in glass curtain walls and container door frames, ensuring air-tightness in high-rise buildings and maritime transport.
Specialized flame-retardant pipes, silicone pipes, and electrical box sealing strips provide protection for wind turbine nacelles and solar inverter cabinets against saline corrosion and UV degradation.
