Customization of multi-way valve seals for automotive thermal management systems——SKY Rubber

         As the core component of automotive thermal management, the multi way valve of automotive thermal management system is composed of precision components such as valve body, valve core, and actuator. The valve core changes position under the drive of the actuator, accurately achieving the on/off and flow distribution of coolant between multiple channels, and efficiently coordinating temperature management of systems such as the engine, battery, motor, and air conditioning. It plays a crucial role in helping the engine quickly heat up, ensuring the stable operation of the battery and motor, and regulating the comfortable temperature inside the car. It has advantages such as high integration, precise control, rapid response, fault diagnosis and protection, and is indispensable in the fields of fuel vehicles and new energy vehicles.

         A Chinese listed automobile manufacturer specializing in the production of automotive thermal management systems encountered difficulties in finding suitable seals for their multi way valves. Due to strict technical requirements, the company consulted multiple domestic Rubber Product manufacturers, but was unable to find a solution that meets the standards. Given that Tiankai Rubber has been deeply involved in the industry for over 20 years, accumulating profound technical expertise and rich experience, the supplier has turned their attention to us, hoping to design and develop ideal multi way valve seals.

After receiving the demand, Tianhe Rubber quickly formed a professional project team and had multiple rounds of in-depth communication with the customer to accurately determine the technical points of the seal: not only should it achieve a complete sealing effect with zero leakage, but it should also reduce friction between components, while ensuring high standards of acid and alkali resistance, wear resistance, temperature resistance, etc., especially to meet the requirements of extreme temperature differences between -40 ℃ and 150 ℃.

         In the face of challenges, the Tianhe rubber engineering team, with their superb professional abilities and repeated research and development verification, innovatively adopted two different rubber materials and perfectly combined them through unique technical processes, successfully overcoming technical difficulties such as sealing and friction reduction, while fully meeting standards in temperature resistance, acid and alkali resistance of seals. At present, this customized automotive thermal management system multi way valve seal has entered the mass production stage. From functional implementation and performance, to quality control and production capacity output, it has far exceeded customer expectations, once again demonstrating Tianhe Rubber's hardcore strength in the field of rubber product customization.
