High-performance TPE, EPDM, and Silicone profiles designed for durability and environmental resistance.
In the modern automotive industry, Thermoplastic Elastomers (TPE) have emerged as the dominant choice for sealing profiles. Unlike traditional thermoset rubber, TPE offers the elastic performance of rubber combined with the rapid processability of thermoplastics. Globally, the automotive sector is shifting toward lightweight, recyclable, and high-performance materials to meet stringent environmental regulations.
As an OEM/ODM TPE Automotive Sealing Profiles Manufacturer, we observe a surge in demand from Europe and North America for materials that are 100% recyclable. TPE profiles are not just about sealing; they are about reducing the overall carbon footprint of vehicle production.
Electric vehicles require superior NVH (Noise, Vibration, and Harshness) control. Our TPE profiles ensure a silent cabin experience by eliminating wind noise effectively.
Global Tier-1 suppliers are prioritizing green procurement. Our TPE solutions are lead-free, halogen-free, and fully recyclable, aligning with circular economy goals.
Modern car designs feature intricate geometries. Our ODM capabilities allow us to extrude multi-component composite profiles that fit perfectly every time.
A leading force in China's automotive parts manufacturing landscape.
Zhejiang Haala Automotive Parts Co., Ltd. (also known in regional operations as Hebei Ruiyuan 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.
The company specializes in producing a vast range of products: 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 handle complex requirements including automotive windshield sealing strips, decorative strips, skeleton strips, and extruded sealing profiles (E-type, P-type, D-type).
Our material expertise covers EPDM rubber, TPE, EPDM sponge (foam), silicone, modified PVC, and composite materials (three-composite, dense-sponge-steel core composite, and soft-hard composite strips).
The company has strong technical strength and management experience. We have invested heavily in high-precision equipment such as EPDM production lines, rubber molding production lines, flat vulcanization machines, and advanced extruders. Our complete testing methods form a one-stop production model: from raw material preparation and mold development to final product molding.
For international buyers, this means unmatched consistency and cost-efficiency. Whether you need container door frame sealing strips, refrigerated door seals, or glass curtain wall strips, our factory direct model eliminates unnecessary middleman costs. We also provide specialized products like fireproof sealing strips, flame-retardant pipes, silicone pipes, and various rubber hoses (water, air, oil).
Our localized application scenarios are diverse. In the Middle East (Iran, Türkiye), our oil-resistant and heat-resistant silicone strips are favored for engine compartments. In northern regions like Russia and Germany, our EPDM and TPE profiles provide excellent weatherproofing against extreme cold (-40°C), maintaining flexibility and seal integrity.
We understand that global procurement is about Reliability. Our "Reputation First" policy drives us to continuously strengthen employee quality awareness. This is why our products are in short supply and highly praised in Japan, the USA, France, Australia, India, Nigeria, and Brazil.
As an integrated manufacturer, we handle:
Explore our specialized range of automotive and industrial sealing profiles.
Professional production of various automotive sealing strips, including high-tech composite skeletons and interior decoration strips.
Our "People-Oriented, Technology-Driven" philosophy ensures that every seal meeting your specification is a testament to our quality seeking development through competition.
From the bustling automotive hubs of Germany to the growing industries of Brazil and Nigeria, our sealing strips provide the quiet, dustproof, and waterproof protection modern vehicles demand.
"The company warmly welcomes people with lofty ideals to come and cooperate and seek common development!"
