What coil processing equipment does Wuxi Jianfa manufacture?

We manufacture complete coil processing lines: slitting lines (rotary shear lines), cut to length lines, flying shear production lines, leveling machines, straightening machines and galvanizing production lines. Equipment can be supplied as a complete line or as individual machines to upgrade an existing line.

Which materials can your slitting and cut to length lines process?

Our lines process hot-rolled, cold-rolled, galvanized, stainless steel and aluminum coils, including high-strength grades. Each line is configured around your thickness range, coil width, yield strength and surface-quality requirements.

How do I choose between a slitting line, a cut to length line and a flying shear line?

Choose a slitting line when you need narrow strips recoiled for tube mills, roll forming or stamping. Choose a cut to length line when you need flat, stacked sheets or plates. Choose a flying shear line when you need high-volume sheet output, because the shear cuts while the strip keeps moving. Combined slitting and cut to length lines are also available.

What information should I send to receive an accurate technical proposal?

Please share the material grade and yield strength, coil thickness and width range, maximum coil weight and inner/outer diameter, required output (strip widths and count, or sheet length range), tolerance and flatness requirements, target line speed and the power supply at your plant.

Do you support installation, commissioning and operator training overseas?

Yes. Our after-sales team supports installation, commissioning and operator training, and continues with remote technical support and spare parts supply after start-up.

Can I visit the factory and inspect my equipment before delivery?

Yes. Buyers are welcome to visit our 40,000 m² facility in Wuxi, Jiangsu, within easy reach of Shanghai by high-speed rail, to review production and inspect their equipment before delivery.

Global Market Architecture

Global Enterprise Procurement Dynamics for Electrical Sheet Stacking Lines

Strategic integration demands for EV traction motors, grid modernization, and high-efficiency transformer manufacturing.

EV Traction Motor Core Stacking

Tier-1 automotive suppliers require specialized production lines capable of processing ultra-thin non-oriented silicon steels (down to 0.20mm - 0.35mm). Core procurement focuses on zero-burr micro-shearing and interlocking stacking to avoid eddy-current losses.

Tolerances strictly held within ±0.01mm
Burr heights controlled below 0.02mm
Automated robotic or air-float stacking

Grid & Transformer Core Plants

Global grid investments demand Grain-Oriented (CRGO) core cutting and stacking lines with step-lap miter shearing. Equipment must protect insulation coatings from physical contact damage and mechanical stress that degrades core loss (W/kg).

Technical FAQ

Engineering Questions on Electrical Sheet Stack Line Systems

In-depth responses from metallurgical and mechanical engineering specialists.

What is the impact of sheet leveling on electrical steel core loss?

Residual stresses induced during coil recoiling alter the domain wall mobility in silicon steel, directly increasing hysteresis and core losses (W/kg). Our multi-roll precision levelers systematically alternate roll bending to eliminate internal stress without breaking the surface insulation coating.

How do you achieve burr-free edges during electrical sheet cutting?

Cutting electrical steels requires precise blade clearances (typically 5% to 7% of sheet thickness) and ultra-rigid machine tool housings. We utilize tungsten carbide or high-alloy powder metallurgy blades supported by pre-loaded precision bearings to keep burrs under 0.02mm.

Can a single stacking line handle both CRGO and CRNGO steels?

Yes. By deploying hybrid magnetic belt and vacuum air-cushion stackers, the line can smoothly transition between grain-oriented sheets (which require delicate mechanical handling) and non-oriented sheets across a spectrum of gauges.

What data points are needed to generate an engineering line proposal?

We require coil outer/inner diameter, maximum coil weight, strip width range, strip thickness range, material yield strength and grade (e.g., M400-50A, CRGO 23Q110), desired sheet lengths, target cycle speeds, and stack bundle height limits.
