C717 50kW Long Size Foam Horizontal Slicer 0.6-70mm Cutting Thickness 0-120m/min for PU Foam Lamination

 Long Size Foam Horizontal Slicer with 0.6-70mm Cutting Thickness and 0-120m/min Cutting Speed for PU Foam Lamination

The C717 long size foam horizontal slicer cuts continuous foam blocks into thin sheets from 0.6mm to 70mm at speeds up to 120m/min. A full servo drive holds cutting precision to ±0.05mm in the 0.6–3mm range, and the machine accepts blocks up to 1300mm high and 1200–2300mm wide with a cutting length of 50m. It is built for foam composite factories that laminate foam into automotive interiors, shoe materials and garment linings.

Horizontal slicing is the step that turns a block of foam into sheets. A block arrives from foaming or from storage, and the slicer peels it into layers of a controlled thickness. Those sheets then go to lamination, die-cutting or packing.

What separates the C717 from a standard horizontal slicer is the length of the work and the thinness of the cut. It is an infinite long horizontal slicing machine: the cutting length is 50m, the block can be 1300mm high and 1200–2300mm wide, and the blade can take sheets down to 0.6mm. Cutting at that thickness is where most machines lose accuracy, because a thin sheet amplifies every vibration and every error in the feed.

The C717 answers that with a full servo driving system. Servo control gives a fast, repeatable response, which is what holds thickness steady when the blade is running at high speed through a long block.

The machine uses full servo motor control across the cutting motion. In practice this changes three things:

• Response: the drive reacts immediately to a command change, so speed adjustments do not lag behind the material.
• Stability: a servo system holds its set speed under load instead of drifting as the blade moves through the block, which is what makes long continuous runs possible.
• Repetition: the same setting produces the same thickness on the first sheet and on the hundredth.

Cutting precision is ±0.05mm within the 0.6–3mm thickness range. That tolerance is the headline figure for this machine, because it covers the hardest part of the job: ultra-thin sheets for lamination, where a few hundredths of a millimetre shows up as visible variation in the finished composite.

Precision also depends on the operator. A sharp blade, a correctly tensioned cut, a clean table and a properly supported block are all part of holding ±0.05mm. The machine provides the capability; the routine protects it.

Cutting thickness is adjustable from 0.6mm to 70mm on the same machine. That range covers two different kinds of work:

• Thin sheet production (0.6–3mm): the precision range, used for automotive interior composites, shoe padding, garment lining and multi-layer lamination where the sheet is one ply of a stack.
• Thicker sheet production (up to 70mm): cushioning layers, padding and structural foam layers that are cut to thickness before shaping.

Having both in one machine means a factory can take a lamination order for thin plies and a padding order for thicker sheets without changing equipment or sending work out. The change is a setting, not a rebuild.

The C717 is a large machine, and the dimensions drive the site planning: overall 102000×6200×2500mm, machine weight 30T, main motor power 50kW.

The 102m overall length comes from the 50m cutting length plus the infeed, outfeed and drive sections. The frame is built to stay straight over that span, because any deflection in the bed shows up as thickness variation in the sheet.

Full servo motors control the cutting motion. This is the component that delivers the 0–120m/min speed range with the response needed for thin-sheet accuracy.

The cutting head traverses the block and sets the sheet thickness. Blade condition is the single biggest operator-controlled factor in sheet quality.

The main motor provides the power for continuous running at production speed. It is sized for long, uninterrupted slicing rather than short bursts.

The control station sets thickness, speed and cut parameters. Guards cover the blade path and the moving carriage, and the emergency stop is placed at the operator position.

The C717 is designed for PU foam and works with the flexible foams used in lamination: PU sponge, and the foam grades used in automotive interiors, footwear and garment lining. Two practical points decide quality:

• Block consistency: a block with density variation slices into sheets with hardness variation. The slicer cannot correct what the foaming step produced.
• Block condition: foam that has been stored damp or compressed in storage will not slice flat. Blocks should be clean, dry and square before they reach the machine.

Very hard or filled foams need a slower feed and a fresh blade. The thickness range stays the same; what changes is the cutting speed at which the tolerance is held.

• Full servo motor control: stable driving system, fast response and reliable long-time continuous production.
• Ultra-high cutting precision: ±0.05mm tolerance, ideal for ultra-thin foam sheets from 0.6mm.
• Wide thickness range: adjustable from 0.6mm up to 70mm for different lamination demands.
• High cutting speed: 0–120m/min, lifting capacity for long foam slicing.
• Long work capability: 50m cutting length, 1300mm cutting height and 1200–2300mm cutting width.
• Global support: remote technical assistance, spare parts supply and installation guidance.

Cutting precision is stated for the 0.6–3mm thickness range. Block quality, blade condition and operating routine all affect the result in production.

• Automotive interior foam: slicing foam sheets for car interior composite materials.
• Shoe material industry: thin foam slices for shoe padding and composite lamination.
• Garment and textile foam: lightweight foam sheets for clothing lining and composite fabric.
• Foam composite factory: long continuous foam slicing for multi-layer foam lamination.
• Mattress and furniture foam: cutting padding layers and cushioning sheets to thickness.

The C717 sits between block production and lamination.

Upstream: foam blocks come from foaming lines or from storage. Their size must fit within the machine's envelope: 1300mm high, 1200–2300mm wide, 50m cutting length. Blocks that exceed these limits must be reduced first.

The C717: the block is sliced into sheets at the required thickness and speed. This is the step where the value of the block is realised, because the sheet count and sheet quality determine the yield of the whole order.

Downstream: sheets go to lamination with fabric, film or other foam layers, then to die-cutting, shaping and packing. Thin sheets from the 0.6–3mm range are normally laminated into multi-layer composites rather than used alone.

Because the slicer sets the thickness of every downstream layer, its accuracy determines how well the lamination stacks. A sheet that is 0.02mm out is invisible on its own, but it changes the thickness of a ten-ply composite.

Planning around the C717 has three variables: cutting speed, sheet thickness and block length.

• Cutting speed: the machine runs from 0 to 120m/min, but the practical speed depends on thickness. Thin sheets require a slower, more controlled pass to hold ±0.05mm; thicker sheets can run faster.
• Sheet thickness: the number of sheets per block is set by the block height and the target thickness. At 0.6mm the sheet count is high and blade condition becomes critical.
• Cutting length: the 50m cutting length allows long continuous runs, which is what the machine is designed for. Stopping and restarting a long block costs accuracy at the joint.

The realistic approach is to run thin-sheet orders at a controlled speed for the whole block, and to reserve the higher speed range for the thicker sheets. That keeps the tolerance where it matters and still uses the machine's speed where it is safe.

• Precision: standard slicers typically quote tolerance in tenths of a millimetre over a narrow thickness band; the C717 holds ±0.05mm across the 0.6–3mm range.
• Drive: mechanical or inverter drives drift under load over a long run; the full servo system holds speed and position.
• Work length: a 50m cutting length and a 102m bed allow continuous long-block slicing, which most workshop slicers cannot handle.
• Thin-sheet capability: cutting at 0.6mm is a different order of difficulty from cutting at 5mm, and it is where the machine's value sits for lamination customers.
• Scale: 30T and 50kW mean this is a production machine for a dedicated line, not a workshop tool.

The C717 is 102m long, weighs 30T and draws 50kW. Site planning is not optional.

• Building length: confirm that the hall can accept a 102m machine with loading and unloading clearance at both ends, plus access for maintenance along the bed.
• Foundation: a level, load-bearing floor designed for the machine's weight and for the dynamic loads of the cutting carriage. Our engineers provide the foundation drawing for the final configuration.
• Power: a supply sized for the 50kW main motor with correct starting protection and cabling. Confirm local voltage and frequency before the order is fixed.
• Environment: stable temperature and humidity help hold tolerance on thin sheets; foam also needs a dry environment to avoid moisture pickup.
• Material flow: plan the layout so blocks enter at one end and sheets leave at the other without a turn that forces manual handling of long, floppy sheets.

Commissioning follows a fixed sequence: foundation and leveling, alignment over the full bed, electrical connection, dry run, trial slices at several thicknesses, precision check with a gauge, then operator training and acceptance.

• Before cutting: check the blade, confirm the thickness setting, verify that the block is square and within the envelope, and check that guards are in place.
• During cutting: never reach into the blade path or the carriage zone. Keep the area clear of loose clothing and tools.
• Sheet handling: thin sheets are fragile and can be pulled into the blade if handled carelessly. Use the outfeed side and the approved handling method.
• Lockout: isolate power before changing the blade, clearing a jam or working inside the machine.
• PPE: gloves and eye protection when handling blades and sheets.

• Daily: clean foam dust from the blade area, the carriage rails and the bed; check that the blade is free of damage.
• Weekly: inspect the blade edge, check the servo drive for abnormal noise, and confirm that the carriage runs smoothly over the full length.
• Monthly: check motor current against the commissioning record, inspect belts and couplings, test guards and the emergency stop.
• Spare parts: keep blades, blade mounting hardware, guide wear parts and filters in stock. Blade lead time is the most common cause of long downtime on a slicer.

Blade life depends on foam type and on how much contamination is in the block. A blade that starts to tear rather than cut should be changed immediately, because torn sheets cannot be laminated.

Each machine is assembled and run before shipment, covering the servo drive, the cutting carriage, the thickness setting and the safety guards. The machine is CE certified.

Shipping a 102m, 30T machine is a project in itself: the bed sections, carriage and control system are packed for container or break-bulk shipment, the loading plan and lifting points are agreed before dispatch, and installation sequencing is planned with the customer. Delivery time is 45 working days after downpayment, with the final schedule confirmed when the order is placed.

1. Block size: confirm height (up to 1300mm), width (1200–2300mm) and cutting length (up to 50m) against your production.
2. Thickness mix: the share of thin sheets (0.6–3mm) determines how much of the time the machine runs in the precision range.
3. Building and power: confirm the hall length for a 102m machine and the supply for a 50kW main motor.
4. Downstream process: tell us whether the sheets go to lamination, die-cutting or packing, so that the thickness and surface requirements are set correctly.

Send these four details and we will confirm the configuration, foundation plan and delivery schedule.
