Why JINDU? Precision Engineering Meets Advanced Thermal Science
JINDU stands at the forefront of the thermal management industry as a premier manufacturer of precision thermal solutions and liquid cold plates. With a robust foundation in high-precision CNC machining, we have strategically expanded our capabilities to cover the full spectrum of advanced thermal manufacturing.
Our state-of-the-art facility is equipped with cutting-edge technologies, including Skiving, Friction Stir Welding (FSW), Soldering, and Vacuum Brazing. This diverse technological portfolio allows us to produce highly complex and efficient liquid cold plates and heat sinks tailored to the most demanding industrial applications.
At JINDU, we go beyond traditional manufacturing. Leveraging our rich machining experience, we position ourselves as a comprehensive solutions partner. We support our customers throughout the entire product lifecycle—from mechanical design suggestions and thermal simulation to heat dissipation analysis. To ensure uncompromising quality and reliability, every solution undergoes rigorous testing, including air tightness tests and precision assembly.
We are dedicated to solving your toughest thermal challenges with precision, innovation, and reliability.

Rapid Response
Quick turnaround from concept to prototype Flexible scheduling to meet urgent timelines
In 2025, Jindu successfully achieved the IATF 16949 certification and passed the Workplace Conditions Assessment (WCA). These milestones reflect our commitment to automotive-grade quality standards, responsible manufacturing, and a safe, sustainable workplace.
To strengthen R&D and product development, we established the Dongguan Nancheng R&D Center. The center focuses on process innovation, Thermal simulation analysis, and prototype development—accelerating our response to customer-specific needs.
With 50 skilled employees, 19 CNC lathing machines and 4 CNC turning machines, we enhanced both capacity and precision. By this year, 82% of our production served overseas clients.
To meet growing international demand, we relocated once again to a 3,200㎡ modern workshop. Our workforce increased to 43, operating 15 CNC machines. Overseas business accounted for 65% of total revenue.
32 peoples with 10 CNC machines, moved to new workshop,factory area: 650㎡,
ISO9001, 40% oversea customers
The team grew to 10 people with 6 CNC machines, and the factory expanded to 400㎡. With increasing orders and stable operations, we began establishing a strong reputation in the domestic market.
JinDu was founded with just three dedicated members and two CNC machines, operating in a modest 200㎡ workshop. From day one, we were driven by precision, craftsmanship, and a vision for long-term growth.
Our Workshop Equipment
We equipped the automatic CMM and projectors, micrometers, color meter and other advanced test equipment, all products have performed 4 times strict inspection at least.
