Changshu Jihong Automotive Electronic Technology Co., Ltd. was established in 2001 and is located in Changshu, Suzhou, Jiangsu Province. It is a “National High-Tech Enterprise”. The company possesses comprehensive capabilities in product R&D, large-scale production, reliability testing, sales, and customer service support. The company has passed the IATF 16949 automotive quality management system certification and strictly follows automotive component industry quality standards throughout the entire R&D, design, and production control process, providing high-quality solenoid valve products and CNC precision components to customers worldwide.
Core Business Segments:
Segment 1: Design, Development, and Production of Solenoid Valves
We provide custom development and volume production for an extensive range of solenoid valves, including normally-open / normally-closed units, proportional valves, carbon-canister purge valves and door-lock solenoids, providing customers with comprehensive product services. The company's solenoid valve products are widely used in carburetor-type products such as general-purpose engines, agricultural machinery, and lawn mowers. Downstream customers include globally renowned companies such as Walbro, Nikki, TK, Ruixing (China), and UCAL (India). End-user enterprises that incorporate our solenoid valves include Kohler (USA), Briggs & Stratton (USA), Yamaha (Japan), Kawasaki Heavy Industries (Japan), Stihl (Germany), Husqvarna (Sweden), Zongshen (China), and Loncin (China).
Segment 2: Solenoid Coils for Various Solenoid Valves
Leveraging its solenoid valve R&D and production expertise, the company has accumulated extensive experience in the development and manufacturing of solenoid coils. As the core functional component of a solenoid valve, the solenoid coil is fully self-controlled throughout the entire process—from material selection, winding, encapsulation, to insulation protection—ensuring the overall operational stability of the solenoid valve and meeting customer requirements for product service life. The company has participated in the development and production of coils for automotive ESP (Electronic Stability Program) braking systems and has partnered with Great Wall Motors (China) to develop solenoid valve coils for hydrogen cylinder valves in hydrogen fuel systems.
Segment 3: CNC Precision Metal Turning
Equipped with imported CNC machine tools, the company performs precision machining on various materials including iron, copper, aluminum, POM, and PEEK. The facility is also outfitted with advanced inspection equipment, including Tokyo Precision coordinate measuring machines (CMM), profile projectors, Keyence measurement systems, and Mitutoyo instruments, providing assurance for delivering high-quality products to customers.
Production Capacity & R&D:
As the business continues to expand, the company now has an annual production capacity of 1.5 million solenoid valve sets, equipped with 4 solenoid valve assembly and testing production lines ensuring a 100% testing rate, over 10 fully automatic solenoid coil winding machines, more than 20 advanced CNC machine tools, and a variety of testing equipment for solenoid valve environmental temperature and service life R&D requirements. The company regards technological innovation as its core driving force for development and has established a professional R&D team that continuously pursues product iteration and technical breakthroughs. The company files multiple invention and Utility Model patents each year, accumulating solenoid valve development technology. It possesses complete technical service capabilities spanning from customer requirement input, R&D and design, sample validation, to mass production—working hand in hand with customers to expand the market and achieve mutual benefit and win-win outcomes.
