Engineer-Verified FAQs
1
3-in-1 Decoiler Straightener Feeder
DSF, GL, GO series combination machines for high-speed press lines
What thickness range does this 3-in-1 combination handle?
Models cover 0.2 mm to 6.0 mm depending on the series. The DSF1 series covers 0.2 to 3.2 mm, the DSF2 series covers 0.5 to 4.5 mm, and the DSF3 series covers 0.6 to 6.0 mm. Each model page lists the exact thickness and width rating, and our application engineers recommend the right series once you share your coil data (grade, thickness, width, coil ID, coil OD and coil weight).Source: FANTY engineering team, reviewed September 2026.
How much floor space does the 3-in-1 combination need?
A typical 3-in-1 unit needs 3 to 5 m of line length, compared with 6 to 10 m for separate decoiler, straightener and feeder machines. The compact layout also shortens the strip path between processes, which improves flatness and feeding accuracy. Exact dimensions for each model are on the product page or in the 2D general arrangement drawing.Source: FANTY engineering team, reviewed September 2026.
Can I use this combination with any punch press?
Yes. We match the feeder interface (mechanical, pneumatic or servo), control voltage (24 V DC, 110 V AC or 220 V AC) and line elevation to your press. Send us your press tonnage, stroke rate, bolster height and die shut height, and our application team confirms compatibility before the order is released to production.Source: FANTY engineering team, reviewed September 2026.
What straightening accuracy is achieved by the combined machine?
Multi-roll straighteners on the combination machines reduce coil set to within 0.5 mm per metre, depending on material grade and thickness. For high-tensile and stainless material we fit heavier work-roll sets and add an adjustable leveling bank, which can bring end-to-end flatness down to 0.2 mm per metre for typical stamping gauges.Source: FANTY engineering team, reviewed September 2026.
What is the delivery time for a 3-in-1 decoiler straightener feeder?
Standard combinations ship in 25 to 35 working days after deposit and approved GA. Lead time covers fabrication, assembly, electrical integration, factory acceptance test with your coil, crating and export documentation. Custom configurations (special voltage, extra straightener rolls, special paint or extended line height) may extend to 45 days, and we confirm the schedule when you place the order.Source: FANTY engineering team, reviewed September 2026.

Press Feeder & NC Servo Feeder
RNC, RF, JSG, NCP series feeders matched to mechanical and servo presses
What press types are these feeders compatible with?
Our feeders work with mechanical (C-frame and H-frame), hydraulic and servo presses. Mechanical roll feeders (RF series) synchronize through the press crank or flywheel linkage. Servo feeders (RNC series) take a reference signal from the press encoder. Gripper feeders (JSG series) feed strip into a die through the press pilot. Zigzag feeders (NCP series) follow circular blanking paths. We match the drive type, mounting flange and control interface to your press model.Source: FANTY engineering team, reviewed September 2026.
What is the maximum feeding speed?
Mechanical roll feeders reach up to 800 strokes per minute (SPM) on a standard press cycle. NC servo feeders exceed 1000 Sprint on short-pitch progressive dies. The actual Sprint your line achieves depends on the part pitch, strip width, feed length and die layout, so we confirm achievable Sprint after reviewing your part drawing.Source: FANTY engineering team, reviewed September 2026.
What feeding accuracy can I expect?
Servo feeders achieve plus or minus 0.05 mm at full speed. Gripper feeders reach plus or minus 0.03 mm for thin materials (0.1 to 1.5 mm). Roll feeders are typically plus or minus 0.1 mm. Accuracy is verified during factory acceptance with a dial indicator on the strip stop, and the HMI logs the actual step position on every cycle for traceability.Source: FANTY engineering team, reviewed September 2026.
What strip thickness range is supported?
NC servo feeders handle 0.2 to 6.0 mm. Roll feeders suit 0.3 to 3.2 mm. Gripper feeders are ideal for 0.1 to 1.5 mm. Strip width is matched to the feeder model (typically 50 to 1500 mm). If your application sits outside these limits, our engineering team can specify a custom roll set or a different feeder model.Source: FANTY engineering team, reviewed September 2026.
How is the feeder controlled?
Servo feeders use a touch-screen HMI with stored job recipes (material, thickness, feed length, acceleration profile, loop tension setpoint). Recipes can be recalled by name or by barcode scan, which makes changeover between SKUs a one-touch operation. Mechanical feeders synchronize through a crank-mounted cam or a flywheel linkage, with jog and inch controlled from a pendant station.Source: FANTY engineering team, reviewed September 2026.
What is a pallet flat decoiler?
A pallet (or horizontal) decoiler holds the coil lying flat instead of on a vertical mandrel. Strip is pulled off the top of the coil by a powered roller drive. This layout suits thin, narrow coil that is hard to thread and keep stable on a conventional vertical decoiler. The flat orientation also avoids the strip twist that thin material can suffer when uncoiled vertically.Source: FANTY engineering team, reviewed September 2026.
Which coil sizes fit the FU series?
Across the FU-500, FU-1000 and FU-2000 models: strip width up to 150 mm, coil thickness 0.1 to 1.0 mm, loading weight from 500 to 1500 kg, loading height up to 600 mm and coil outside diameter up to 1200 mm. The model number is the maximum coil weight in kilograms. Check your coil outside diameter and weight against the table above to pick the model.Source: FANTY engineering team, reviewed September 2026.
Can it feed very thin strip without jamming?
Yes. The FU series is designed around 0.1 to 1.0 mm material. The motorized drive with Mitsubishi inverter keeps payout smooth, and flat coil orientation avoids the strip twist that thin material can suffer on vertical mandrel machines. For ultra-thin strip under 0.2 mm, we add a pinch roller set and a dancer arm to control loop tension precisely.Source: FANTY engineering team, reviewed September 2026.
How is the coil loaded?
The coil is placed flat into the cradle opening with a crane or hoist. The flat design means the coil does not have to be lifted onto a high vertical mandrel, which makes coil handling simpler for lighter operations. Loading takes under two minutes for the FU-500 and under five minutes for the FU-2000.Source: FANTY engineering team, reviewed September 2026.
Can it feed my existing press line?
In most cases yes. FANTY supplies complete coil-fed lines, so we can pair the FU pallet decoiler with a straightener and servo feeder matched to your press. Send your press model, material width, thickness and part pitch for an integration recommendation, and we will return a one-line general arrangement drawing within one working day.Source: FANTY engineering team, reviewed September 2026.
How does hydraulic mandrel expansion work?
A hydraulic cylinder expands the mandrel segments outward to grip the coil inner diameter, giving uniform pressure that is safer and faster than hand-wheel expansion on heavy coils. The operator simply pushes one button on the HMI, and the segments close on the coil ID in a controlled, repeatable way. Mandrel wear is also reduced because the segments expand in parallel rather than being torqued unevenly.Source: FANTY engineering team, reviewed September 2026.
What coil weights can it handle?
FANTY hydraulic decoilers are built for coils from roughly 3 to 20 tons. The MT-3000 handles up to 3 tons, MT-5000 up to 5 tons, MT-10000 up to 10 tons, MT-15000 up to 15 tons and MT-20000 up to 20 tons. Send your coil weight, OD, ID and width, and we will confirm the model and mandrel size.Source: FANTY engineering team, reviewed September 2026.
Can it run with my existing straightener and feeder?
Yes. FANTY builds complete coil-fed press lines, so we can match this decoiler to your existing straightener and feeder or supply the full line. The control interface is a single 24 V DC run signal plus an alarm contact, which is compatible with most modern straightener-feeder controllers. Mechanical interface is a flanged strip entry guide that bolts to the straightener head.Source: FANTY engineering team, reviewed September 2026.
What controls are included?
The control panel covers jog, forward and reverse, and speed (via inverter). Heavier models add coil-car and pressing-arm controls. The HMI shows mandrel pressure, payout speed, coil diameter (calculated from strip length), and alarm status. Recipes store mandrel pressure and brake torque for each coil size, which makes changeover repeatable between shifts.Source: FANTY engineering team, reviewed September 2026.
How is the machine shipped?
Each unit is run-tested with coil, then partially disassembled for export. The mandrel, base and control cabinet are fixed in a wooden export crate with moisture barrier. English manuals, wiring diagrams, hydraulic schematics and a starter spares list are supplied in a waterproof document wallet. Lead time is 25 to 35 working days for standard models.Source: FANTY engineering team, reviewed September 2026.

What coil sizes can these decoilers handle?
Models range from 200 mm to 1500 mm coil widths and from 500 kg to 20 tons coil weight. Heavy-duty decoilers (MT-H series) handle the largest coils up to 20 tons. Double head decoilers (DBMT series) hold two coils side by side for continuous line operation. Manual decoilers suit lighter coils up to 500 kg. Tell us your coil data and we recommend the right model.Source: FANTY engineering team, reviewed September 2026.
Do you provide voltage and plug customization?
Yes. Control voltage (24 V DC, 110 V AC or 220 V AC), motor voltage (380 V, 415 V, 480 V, 50 or 60 Hz) and plug type are configured to your local standard before shipping. We also pre-set the inverter and HMI language to your country, so the machine arrives ready to plug in and run.Source: FANTY engineering team, reviewed September 2026.
How long is production and delivery?
Standard models ship in 15 to 25 working days after deposit. Custom configurations (special voltage, custom paint, extra control I/O, integrated coil car) may need 30 to 40 days. We confirm the schedule when you place the order, and the order confirmation includes a milestone chart with the engineering, fabrication and shipping dates.Source: FANTY engineering team, reviewed September 2026.
What spare parts should I keep in stock?
We recommend keeping mandrel segments, brake pads, proximity sensors and one spare inverter in stock. A starter spare-parts list is included with every machine, and our service team can ship critical spares by air within 48 hours for urgent breakdowns. We also offer a recommended spares kit sized to your specific machine configuration.Source: FANTY engineering team, reviewed September 2026.
What is the warranty period?
One year from the bill of lading date. Technical support and replacement parts are available for the lifetime of the machine. Warranty covers manufacturing defects and component failures under normal use; wear items (brake pads, mandrel segments) are replaced at cost. Extended warranty and service contracts are available on request.Source: FANTY engineering team, reviewed September 2026.
What tonnage range do you offer?
We supply presses from 25 tons to 1000 tons in C-frame, H-frame and gantry configurations. C-frame presses suit smaller parts and shorter tooling. H-frame (C2N) presses handle longer dies and heavier parts. Gantry presses are built for very long progressive dies used in lamination and motor core stamping. The model number encodes the series and tonnage.Source: FANTY engineering team, reviewed September 2026.
What is the maximum stamping speed?
High-speed models reach 800 to 1200 strokes per minute (SPM) depending on stroke length, die complexity and material feed characteristics. The GS series is built around high-speed lamination and motor core dies. C2N and T2N series suit precision progressive dies running at 400 to 800 SPM. Actual SPM depends on part pitch, material grade and die design.Source: FANTY engineering team, reviewed September 2026.
What die sizes fit these presses?
Bolster and slide dimensions vary by tonnage and frame style. We provide a die-fit chart for each model to confirm compatibility. Common bolster sizes range from 700 mm x 500 mm on the smallest C-frame presses to 3000 mm x 1500 mm on the largest gantry presses. Slide dimensions follow the bolster and are sized to match typical die guide pins.Source: FANTY engineering team, reviewed September 2026.
What safety features are included?
Standard features include two-hand buttons, light curtains, overload clutch and emergency stop. Higher-tier safety packages add Cat-3 safety PLC, dual-channel E-stop, fixed perimeter guards, interlocked access doors and a die-clamp confirmation sensor. CE-marked models include the full EN ISO 16092 safety package.Source: FANTY engineering team, reviewed September 2026.
Can the press voltage be customized?
Yes. Motor and control voltages are configured to your local standard before shipment. We support 380 V, 415 V and 480 V at 50 or 60 Hz, plus control voltages of 24 V DC, 110 V AC and 220 V AC. Plugs and connectors are matched to your country standard, and the inverter and HMI language are pre-set for plug-and-play on arrival.Source: FANTY engineering team, reviewed September 2026.
