Liming Machinery Team: 35 Years of Cold Forming Craftsmanship, Defining Industry Benchmarks with Expertise

At Xiamen Liming Metallurgical Machinery, our team is never just “executors”—they’re the core force behind our leadership in cold forming machinery, especially roll forming machines.
 
The R&D team is the “engine” of technical breakthroughs—over 30 senior engineers form a municipal-level tech center, holding 120+ patents (including 18 invention patents) to drive innovation. From smart servo control systems to modular quick-change technology, every breakthrough stabilizes roll forming precision at ±1mm, turning clients’ custom roll forming machine needs from blueprints to finished products seamlessly.
 

The production team is the “gatekeeper” of quality—with a master-apprentice inheritance model plus 145 precision processing devices, they strictly control 10 quality checks from roller quenching to frame welding, ensuring every roll forming machine withstands extreme working conditions.
 
The service team is clients’ “peace of mind”—a fast-response engineer squad handles everything from equipment installation, debugging to operation training, and provides on-site support at overseas construction sites and remote smart maintenance. They keep clients worry-free for major projects like Wuhan Greenland Center and Qatar World Cup venues.
 
With 35 years of industry experience, our team’s DNA of “bold R&D breakthroughs, production attention to detail, and warm service” makes “Liming-made” the global clients’ synonym for “high-precision, high-reliability” roll forming solutions.
