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.

Knowledge Base

Frequently Asked Technical Questions (FAQ)

In-depth responses compiled by senior metallurgical machinery engineers at Wuxi Jianfa.

What is the difference between air-float and vacuum gantry stacking?

Air-float stackers blow a low-pressure air pocket underneath running sheets, allowing them to glide forward without friction before dropping onto the stack table. Vacuum gantry systems use suction cup matrices on a moving overhead arm to pick up the cut plate from the runout table and place it down gently. Vacuum gantries are preferred for non-ferrous and scratch-sensitive materials like automotive aluminum and bright annealed stainless steel.

How does an automatic stacker achieve non-stop line running?

Non-stop continuous operation is achieved using dual-station cassette stackers or automated runout scissor tables. Once stacker station A reaches its predetermined bundle count or weight limit, an overhead switch diverts subsequent cut sheets seamlessly into stacker station B. Station A then lowers, unloads the bundle onto an outgoing rollway, and returns to position without slowing the cut-to-length line.

Which parameters are critical when drafting an RFQ for a coil stacker?

Ensure your request specifies: (1) Material yield strength and elongation, (2) Gauge thickness and strip width ranges, (3) Minimum and maximum cut lengths, (4) Line speed target, (5) Maximum bundle weight and height, (6) Surface finish sensitivity (oiled, dry, prepainted, mirror), and (7) Required pack discharging orientation (longitudinal or cross-direction).

Can Jianfa stacker modules retrofit existing competitive CTL lines?

Yes. Our engineering division routinely engineers retrofit stacking units for lines built by third-party manufacturers. We match mechanical centerline elevations, belt conveyor feeds, and establish an interlocking Profinet, Ethernet/IP, or dry-contact handshake with your line's existing master controller.
