As global automotive OEMs shift toward 800V super-charging platforms, battery pack thermal management has emerged as a critical safety and efficiency frontier. Traditional coolant hoses, such as EPDM, are facing limitations due to high permeation, weight, and assembly constraints. The industry's solution is the Knitted Reinforced TPV (Thermoplastic Vulcanizate) Hose.
TPV combines the processing flexibility of thermoplastics with the elastomeric performance of vulcanized rubber. By integrating high-tensile fiber knitting layers within TPV structures, these coolant hoses maintain dimensional stability, withstand operating pressures of up to 10-15 bar under continuous thermal stress, and reduce overall weight by 30-40% compared to traditional rubber components.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) has engineered a state-of-the-art continuous co-extrusion line that integrates multi-layer TPV extrusion with online high-speed knitting technology. This system eliminates secondary processing, dramatically reducing manufacturing costs while guaranteeing high interfacial adhesion and dimensional precision.
Founded in 2002, BAOD EXTRUSION is dedicated to designing, manufacturing, and selling high-end plastic extrusion machinery. Leveraging design principles inherited from our original Taiwan parent company (KINGSWEL GROUP), we offer optimized manufacturing lines that focus on:
The foundation of the hose's structural integrity. Focuses on the precise geometry of the inner layer.
Reinforces the structural pressure barrier to prevent expansion under cooling system pressurization.
Adds the protective outer layer that resists road debris, environmental chemicals, and heat.
Globally, automotive component manufacturers face immense cost pressures from EV makers like Tesla, BYD, and European legacy OEMs. Upgrading to advanced, automated extrusion systems is the only way to balance quality and margins.
China-based manufacturing has transitioned from a cost-only alternative to a hub of precision machinery innovation. With BAOD's machinery, manufacturers receive:
Battery cooling loops require hoses that do not contaminate the coolant, have low permeability to prevent loss of cooling media, and maintain performance from -40°C to 135°C.
*Note: Upgrading to TPV hoses reduces total vehicle assembly mass, which directly increases battery range—a key metric for modern EV models.
Integration of real-time monitoring to adapt process controls instantly without manual operator inputs.
Advancing from simple single-layer extrusions to complex multi-layer configurations with specialized functions.
Aligning manufacturing technology with sustainability objectives to meet carbon neutrality standards.
Exporting complex machinery to regions such as North America and Europe requires adherence to strict electrical and safety specifications. BAOD ensures compliance across multiple frameworks.
BAOD maintains a 16,000 square meter ISO 9001:2015 certified production facility in Jiangsu. Every extrusion line undergoes a rigorous 72-hour pre-shipment dry run with raw materials to confirm dimensional stability and extrusion speed.
