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 and a strategic location in the Matun Industrial Zone, Qinghe County, we have mastered the art of rubber extrusion.
We specialize in producing a diverse array of sealing solutions: EPDM rubber sealing strips, door/window strips, foam seals, and complex multi-material composites. Our "Information Gain" approach to manufacturing means we don't just supply parts; we solve engineering challenges related to NVH (Noise, Vibration, and Harshness) reduction, waterproof integrity, and aesthetic finish.
In today's volatile global automotive market, supply chain resilience is paramount. Our factory utilizes a "One-Stop Production Model"—from raw material compounding (EPDM, Silicone, PVC) to mold development and precision extrusion. This internal control allows us to pivot quickly to meet specific client requirements, ensuring minimal lead times even in fluctuating markets.
Looking ahead, we are investing in eco-friendly EPDM foaming agents and recyclable thermoplastic elastomers (TPE). We recognize that the future of automotive sealing lies in lightweight materials that enhance fuel efficiency while maintaining rigid sealing performance against dust, water, and ambient noise.
Automotive seals must perform across extremes. Our products are engineered with thermal stability—maintaining elasticity in -40°C freezing conditions in Russia/Northern Europe, and preventing UV degradation and hardening in the high-heat environments of the Middle East or Southeast Asia. Our R&D team performs rigorous aging tests to ensure our seals exceed OEM lifecycles.
Our product portfolio is vast: E-type, P-type, D-type seals, dense sponge steel core composites, and fireproof strips. By utilizing advanced vulcanization technology, we ensure consistent cross-linking in our rubber compounds, resulting in superior compression set resistance.
Our Capabilities Include:
We operate under strict QC protocols. From raw material preparation (testing viscosity and density) to in-line dimensional monitoring using laser scanning, every meter of our extrusion is verified.
Yes, we have an internal mold development department. Send us your CAD or PDF files, and our engineers will provide a DFM (Design for Manufacturing) report within 48 hours.
Depending on the complexity and volume, our lead times range from 7 to 20 days. Our high capacity ensures we maintain stock for common profiles.
