C616 11kW Foam Splitting Machine 6-1200mm Cutting Thickness 0-60m/min for Mass PU Latex Foam Slicing

 Micro-tooth Cutter Foam Splitting Machine with Computer Nesting System for 6-1200mm Foam Slicing

The C616 foam splitting machine slices large PU and latex foam blocks into sheets from 6mm to 1200mm thick at speeds up to 60m/min. It uses a micro-tooth cutter structure that removes the need for frequent knife sharpening, and a computer nesting system that supports batch production planning. Blocks up to 3500×2100×1250mm are handled by an 11kW drive, and the cut surface is clean enough to go straight into vertical cutting or CNC profiling.

Splitting is the first cut a foam block receives. A block arrives from foaming or storage at full height, and the splitter divides it horizontally into sheets of the required thickness. Everything downstream — vertical cutting, contour cutting, lamination, packing — starts from those sheets.

The quality of the split face decides how much work the next stages need. A torn or wavy surface has to be trimmed or accepted as scrap, and a sheet that is not flat does not laminate cleanly. The C616 is built around a micro-tooth cutter that produces a neat cutting surface, so the sheet can move to vertical cutting or CNC profiling without extra preparation.

The machine is also fast. Cutting speed runs from 0 to 60m/min, which is what makes it suitable for mass production rather than job-by-job cutting, and the thickness range covers everything from a 6mm lamination ply to a 1200mm block section.

Blade maintenance is the hidden cost of foam splitting. A conventional blade dulls, the cut starts to tear, and production stops while someone sharpens or changes the knife. On a machine running all shift, that cycle repeats far more often than the purchase price suggests.

The C616 uses a micro-tooth cutter structure. The toothed edge keeps cutting as it wears over a longer interval, which removes the frequent sharpening routine and keeps cutting quality stable between services.

• Less downtime: fewer stops for sharpening means more production hours from the same shift.
• Steadier surface: a cutter that stays sharp produces a consistent face, so sheet quality does not drift through the day.
• Lower consumable cost: fewer blades and less labour spent on maintenance.

The thickness range is the specification that decides which orders a machine can take. On the C616 the range runs from 6mm to 1200mm, and that span covers two different jobs in the same machine:

• Thin sheets (6mm and up): lamination plies, mattress and furniture layers, packaging inserts.
• Thick sections (up to 1200mm): splitting a full block down to the working height needed for the next process.

Because the thickness is adjustable across the whole range, a plant can take a mixed order book without changing machines. Thickness is set on the control, and the sheet is cut at the set value.

The C616 is equipped with a computer nesting system. In foam production, nesting means planning how the required pieces are laid out across the block so that material use is maximised and the cutting sequence is efficient.

For batch production of PU foam and latex foam, that planning is what separates a profitable run from a wasteful one. The nesting system supports typesetting of the cutting plan, so the operator works from a defined layout rather than deciding cut by cut.

The practical effect is fewer offcuts, a predictable cutting sequence and less time spent measuring. It also makes the machine easier to hand over between shifts, because the plan is recorded rather than remembered.

The machine measures 5000×3600×2700mm and weighs 3.5T. The frame carries the cutter across a maximum cutting size of 3500×2100×1250mm, which is the full block section the machine is designed to split.

The cutter is the heart of the machine. Its toothed structure maintains cutting performance over a long service interval and produces the neat surface the downstream processes need.

An 11kW motor drives the cutting motion across the 0–60m/min speed range. The power is matched to full-section cuts, where the cutter meets the most resistance.

The control station sets thickness and speed and runs the computer nesting system. Guards cover the cutter path, and the emergency stop is at the operator station.

The C616 is designed for mass cutting of PU foam and latex foam. The two behave differently and the machine settings should reflect that.

• PU foam: cuts cleanly across the full thickness range. Soft grades need a steady feed to avoid compression at the cut face.
• Latex foam: denser and more elastic, so it resists the cutter more and springs back after the cut. A slightly slower pass gives a cleaner face.
• Mixed production: when switching between materials, reset the speed rather than carrying a PU setting across to latex.

Blocks should be clean and free of hard inclusions. Metal, wood or cured foam lumps damage the micro-tooth cutter, and a damaged cutter shows up immediately as a torn sheet.

• Micro-tooth cutter design: no frequent knife sharpening required, saving maintenance time and cost.
• High cutting precision and neat surface: a clean foam cutting surface that is convenient for later vertical cutting and CNC contour cutting.
• Computer nesting system: supports computer typesetting and is suitable for batch PU foam and latex foam production.
• Wide cutting thickness range: adjustable from 6mm to 1200mm for different slicing demands.
• Production speed: 0–60m/min cutting speed with an 11kW motor for mass cutting.
• Global support: remote technical assistance, spare parts supply and installation guidance.

Cutting thickness and speed are set on the control. Material grade, block condition and cutter condition all affect the finished surface.

• PU foam production: slice large PU foam blocks into sheets for the furniture and mattress industry.
• Latex foam processing: mass cutting of latex sponge sheets for bedding and cushion products.
• Foam deep processing factory: prepare foam sheets for follow-up vertical cutting and CNC profiling.
• Packaging material production: split blocks into sheets for shock-proof packaging.
• Lamination lines: produce thin plies for multi-layer foam composites.

The C616 sits at the front of the conversion process, directly after foaming.

• Upstream: blocks arrive from foaming or from storage. They must fit the maximum cutting size of 3500×2100×1250mm; larger blocks need to be reduced first.
• The C616: the block is split into sheets at the required thickness. Because the cut face is clean, the sheet goes to the next stage without trimming.
• Downstream: sheets go to vertical cutting, CNC contour cutting, lamination or packing. A flat, clean sheet cuts faster on a vertical machine and profiles more accurately on a CNC machine, which is why the split quality has a knock-on effect through the whole plant.

Three variables set the practical output of the C616: block size, sheet thickness and cutting speed.

• Block size: a full-section cut at 3500×2100mm takes longer than a narrow cut, so the largest blocks set the floor for cycle time.
• Sheet thickness: a 6mm sheet means many more cuts per block than a 100mm sheet. Thin-sheet orders are cycle-heavy.
• Cutting speed: the 0–60m/min range allows fast passes on straightforward work; dense latex or very thin sheets need a controlled speed for surface quality.

Plan production around the slowest of these three, then use the nesting system to lay out the block so that the cutting sequence wastes as little material and time as possible.

• Cutter maintenance: a band knife needs frequent sharpening and blade changes; the micro-tooth cutter on the C616 runs longer between services.
• Surface quality: a dull band knife leaves a torn face that needs trimming; the toothed cutter produces a neater surface for downstream processing.
• Thickness range: 6–1200mm in one machine covers both thin plies and thick sectioning.
• Batch planning: the computer nesting system supports planned layout, while manual cutting depends on operator judgement.
• Material range: designed for both PU foam and latex foam, which are the two materials most often run in the same plant.

The machine measures 5000×3600×2700mm and weighs 3.5T, so the layout should be planned before delivery.

• Floor: a level, load-bearing concrete floor. The machine is heavy and the cutting loads pass through the frame.
• Space: clearance at the infeed and outfeed for block handling, plus access along the cutting side for maintenance.
• Power: a supply sized for the 11kW motor with correct protection. Confirm local voltage and frequency before the order is fixed.
• Environment: keep the machine area dry and free of loose foam offcuts that could jam the cutter path.
• Material flow: place the splitter so that blocks move in a straight line from storage to splitting to the vertical cutting or CNC station.

Commissioning includes a dry run, alignment checks, trial cuts at thin and thick settings, a surface quality check, and operator training on the nesting system.

• Before cutting: confirm the thickness setting, check the cutter and guards, and verify that the block is within the maximum cutting size.
• During cutting: stay clear of the cutter path. Never reach across the block while the machine is running.
• Block handling: large blocks and thick sheets are heavy. Use the approved handling equipment.
• Lockout: isolate power before changing or inspecting the cutter, clearing a jam or entering the machine area.
• PPE: gloves and eye protection when handling the cutter and cut sheets.

• Daily: clean foam dust from the cutter area and the guides; check that the cutter is undamaged.
• Weekly: inspect the cutter edge, check the drive for abnormal noise, and confirm that the cutting dimension matches the setting.
• Monthly: check motor current against the commissioning record, inspect belts and fasteners, and test guards and the emergency stop.
• Spare parts: keep cutter assemblies, guide wear parts and drive belts in stock. Cutter lead time is the most common cause of extended downtime.

The micro-tooth design reduces sharpening frequency but does not remove the need for inspection. A chipped tooth should be dealt with before it tears a production run.

Each machine is assembled and run before shipment, covering the cutter drive, the thickness setting, the nesting control and the safety guards. The machine is CE certified.

At 5000×3600×2700mm and 3.5T, the machine is packed for container shipment with the cutter head and control panel protected against transit damage. Delivery time is 45 working days after downpayment, and the final schedule is confirmed when the order is placed.

1. 1Block size: confirm the height, width and length against the maximum cutting size of 3500×2100×1250mm.
2. 2Thickness mix: the share of thin sheets (6–20mm) determines how much of the time the machine runs at controlled speed.
3. 3Material: PU foam, latex foam or both, since the setting differs between them.
4. 4Downstream process: tell us whether sheets go to vertical cutting, CNC profiling or lamination, so that surface requirements are set correctly.

Send these details and we will confirm the configuration and delivery schedule.
