Factory-direct high-precision coil uncoiling, slitting, leveling, and cut-to-length lines configured for cold-rolled, hot-rolled, and electrical steel substrates.
Established in the early 1980s, Wuxi Jianfa Machine-Building Co., Ltd. has developed into a national key enterprise within China's metallurgical machinery sector. Operating from a modern 40,000 m² facility with 45 million RMB in registered capital, we specialize in high-end coil processing machinery engineered for the global market.
All heavy frame fabrication, high-precision arbor grinding, hydraulic integration, and PLC electrical controls are manufactured directly in-house in Wuxi to eliminate outsourcing quality risks.
High-torque performance across cold-rolled coil, hot-rolled carbon steel, silicon steel, aluminum, pre-painted substrates, and high-tensile structural automotive alloys.
Over 40 years of successful global turnkey deliveries spanning North America, Europe, Southeast Asia, South America, Central Asia, and Africa with certified international commissioning teams.
Driven by automated modern manufacturing and the rapid growth of the electric mobility and energy infrastructure sectors, coil processing lines are moving beyond mechanical slitting into closed-loop intelligent processing systems.
Traditional manual knife repositioning can take 40 to 60 minutes per production run. Modern CNC slitter arbors utilize automated knife setup units, reducing changeover cycles down to under 5 minutes while eliminating knife handling errors.
The structural shift toward Advanced High-Strength Steels (AHSS, up to 1200 MPa yield) and thin silicon steel sheets for EV drive motors requires higher spindle rigidity, dynamic tensioning systems, and near-zero knife arbor runouts.
Digital camera arrays and laser telemetry scan the moving strip at speeds up to 250 m/min. The system flags camber deviations, slivers, strip width tolerances, and knife micro-wear in real time, preventing full-coil quality waste.
Choosing the right line architecture requires balancing finished product form factor, material yield strength, line speed, and surface quality requirements.
