Thirty Years Turning Steel Coil into Precision.
KingJime builds the coil-processing lines the world's manufacturers run every day — engineered in-house, installed on-site, and backed for the long haul.
KingJime Production Line — Customer Installation
From a Single Breakthrough to a Global Catalog
In 1996, in the industrial town of Qingxi near Dongguan, a small workshop set out to solve a problem that China's fast-growing manufacturers were struggling with: how to feed steel coil into a press quickly, accurately, and safely. Drawing on engineering experience brought over from Taiwan, the team built the country's first press-feed coil automation line — the 3-in-1 NC servo feeder.
That first machine defined us. As demand grew, the workshop was restructured into KingJime Machine Co., Ltd., and the product line expanded to cover the entire coil-processing journey: slitting, cut-to-length, leveling, shearing, tube-making, and eventually die-less laser blanking.
“We don't sell off a shelf. Every line is built to a customer's specific coil.”
KingJime engineers and manufactures every line in-house on a 50,000 m² campus in Qingxi, supported by three subsidiaries — in the United States, Hong Kong, and Suzhou — and a network of branch offices across China. Our 260-strong team includes 50 senior technical specialists and 150 skilled tradespeople.
Our machines run in 58 countries — from India, Indonesia, and Vietnam to the Middle East, Brazil, Europe, and North America. They sit inside plants operated by Foxconn, Haier, Midea, Dongfeng, TATA, Emerson, Mahle, and Valeo, among many others.
Industrial buyers don't reorder from suppliers who let them down. On Alibaba, our reorder rate is 100% — a number we're prouder of than any slogan.
“Being professional is the foundation. Innovation is the engine. Honest service is the key to a wider market.”
