Not long ago, the *Kunshan Daily* highlighted our production workshop under the spotlight with the headline, "0.01 Millimeters! This 'Blue Light' Is More Delicate Than a Sewing Needle."
To be honest, when journalists entered the workshop and witnessed the automated equipment operating smoothly while the slender welding torches moved with the agility of sewing needles, they were amazed by how this environment shattered the traditional impression of welding—typically associated with sparks flying and steel blossoms dancing. This "agile light blade" of blue arc precisely embodies the decades of dedicated effort and relentless innovation by our Limah team.
The Starting Point of "Microcarving Art": A Pursuit of Precision from Conquering 0.01mm
The phrase mentioned in the report—"ultra-precision welding technology can be called the 'micro-carving art' in the field of metal processing"—is actually a saying often repeated by our general manager, Li Jian'an. We are not merely welding metals; we are "embroidering" in a micrometer-scale space.
Over the years, one of our most proud breakthroughs has been mastering the welding challenge of 0.01mm ultra-thin metal films. You may not grasp the scale of this thickness—it's roughly one-fifth the diameter of a human hair. To tame this "blue light," our technical team conducted countless experiments, successfully refining welding current control precision to the 0.01 ampere level—several times the standard achieved by domestic peers.
It is this relentless pursuit of precision down to the "micron" level that enables our MICRO-ARC series equipment to be specifically designed for welding ultra-thin materials ranging from 0.03mm to 1mm. It can even achieve single-sided welding and double-sided forming, eliminating the bottleneck of "membrane" welding in the semiconductor industry.
Not just equipment, but a full-chain "intelligent manufacturing" system
The lens of *Kunshan Daily* captured the air suspension accumulator of the car displayed by product manager Li Hongfei. These metal sheets, each only 0.05 millimeters thick, were welded together through our advanced process and ultimately applied to products of leading domestic new energy vehicle manufacturers, significantly enhancing ride comfort when traversing bumpy roads.
Behind this lies our comprehensive precision intelligent manufacturing system, spanning from raw material processing to finished product production. We don't just sell automatic welding machines or corrugated pipe welding machines—we deliver customized solutions tailored to high-end sectors such as vacuum semiconductors, instrumentation, and new energy vehicles. Whether it's flexible pipe automatic welding machines or complex overlay welding automation production lines, we strive to perfect every detail.
As everyone has seen, since 2025, we have continuously received numerous prestigious honors: not only obtaining the dual certifications of ISO9001 and ISO14001, which represent international top-tier management standards (TÜV Rheinland), but also being recognized as Jiangsu Province's "Specialized, Refined, Distinctive, and Innovative SMEs" and "Gazelle Enterprises." Additionally, we successfully made it into the large-scale brand enterprise documentary program "China's Manufacturing Power." Now, with high-profile reports from two major party newspapers, the *Suzhou Daily* and the *Kunshan Daily*, we truly feel that "deep specialization yields its own resonance.".
Last year, our revenue exceeded 70 million yuan, doubling year-on-year. Our products were exported to 12 countries and regions, and we have served over 1800 customers in total. These numbers are a summary of the past and a driving force for the future. The square inch welding gun not only welds materials, but also helps China's intelligent manufacturing move towards a higher level of infinite future.
