±0.05 mm Horizontal Foam Slicing Machine for 0.5-2 mm Sheet at 2200 mm Width

The TDB-2200 is a horizontal foam slicing machine built for the thin end of the range. It takes blocks up to 3000*2200*1250 mm, slices them from 0.5 mm to 70 mm, and holds ±0.05 mm on sheet between 0.5 mm and 2 mm. The main drive is 23 kW, machine weight is 6000 kg, the overall size is 8300*6200*2500 mm and the machine is CE certified.

Thin sheet is where a slicer is judged. At 0.5-2 mm the foam has almost no stiffness of its own, so any movement in the block, the blade or the feed shows up directly in the thickness. The TDB-2200 is set up around that problem: a wide, stable table for the block, a cutting head that holds its line across 2200 mm of width, and a frame heavy enough that the cut does not find movement in the machine.

1. Square the block. Trim the faces so the block sits flat and square to the feed line.
2. Load it on the table. Place the block inside the 3000*2200 mm area and seat it against the fence.
3. Set the thickness. Choose the sheet thickness, 0.5 mm to 70 mm, for the order.
4. Start the pass. The head advances and the blade takes the first sheet off the block face.
5. Take off and stack. Remove each sheet as it is cut and stack it flat.
6. Repeat to the end of the block. The setting stays; only the block is reloaded.

The first sheet of a block is the sample. Measure it at both edges and in the middle, and if it sits inside ±0.05 mm the rest of the block will follow, provided the block is square and the blade is sharp.

At 0.5-2 mm the sheet is thin enough that a 0.05 mm error is five percent of the thickness. That error can come from the machine, but more often it comes from the material: a block face that is not flat, a block that is not seated, or foam that has taken a set from storage. Checking the block before the pass is cheaper than checking the sheet after it.

The blade is the second variable. A dull blade compresses the foam before it cuts, and the sheet springs back thinner at the entry edge than the middle. On thin sheet that reads as a taper along the block. Check the edge at the start of each shift rather than when the sheet looks wrong.

The third variable is heat. Foam softens as the workshop warms, and a setting that produced 0.5 mm sheet in the morning can produce 0.55 mm sheet after the heating comes on. Note the workshop temperature in the batch log and re-check the first sheet after any change.

• Square block, square sheet: a sloped face produces a tapered first sheet every time.
• Sharp blade: compression at the entry edge is the most common cause of a thin-sheet taper.
• Stable temperature: check the first sheet after a shift in workshop temperature.

• Thin sheet tolerance: ±0.05 mm is held on 0.5-2 mm sheet, which is the range where a mattress comfort layer is actually measured.
• Wide block capacity: 3000*2200*1250 mm covers full mattress-size blocks, so one block yields a batch of sheets rather than a handful.
• Range without a rebuild: 0.5 mm to 70 mm on the same machine, from backing sheet to thick padding.
• Stable cut across the width: the head holds its line over 2200 mm, so the sheet does not thin out at the far edge.
• Heavy frame: 6000 kg of machine takes the vibration that thin sheet cannot tolerate.
• 23 kW drive: enough power to hold feed rate through a dense block instead of slowing in the cut.
• CE certified: guarding and electrics are built to the CE standard for export markets.

• Mattress comfort layers: 0.5-3 mm sheet for quilting and comfort foam.
• Furniture upholstery: thin backing and padding sheet.
• Lamination: uniform thin foam for flame lamination and fabric bonding.
• Packaging: thin protective sheet and interleaving foam.
• Footwear: lining and insole sheet at a controlled thickness.
• Filter and acoustic products: thin open-cell sheet cut to a fixed thickness.

Most sheet complaints trace back to the first slice of a block, not to the machine. Cut one test sheet, measure it at both edges and the middle, and the correction costs one slice instead of a full shift of scrap.

The machine occupies 8300*6200*2500 mm and weighs 6000 kg, so it needs a level floor and clear space on the take-off side for full 2200 mm sheets. A table that is narrower than the sheet forces the operator to fold it, and a crease in a 0.5 mm sheet is scrap.

Keep a log per block: foam grade and density, block size, thickness setting, blade hours and the measurement from the first sheet. When a buyer reports a thin comfort layer, the log shows whether the cause was the block, the setting or the edge.

• Guarding: keep the head guard in place and the emergency stop within reach of the take-off position.
• Loading: use a lift or a roller table for 1250 mm blocks instead of tipping them onto the machine.
• Handling thin sheet: stack on a flat pallet; a 0.5 mm sheet takes a permanent crease if it is folded.
• Dust: clear foam dust from the table and the head at the end of each shift.

The blade and the guide decide whether thin sheet stays inside tolerance. Check the edge every shift, keep the guide clear of dust, and follow the sharpening interval for the foam grade. A blade that is only slightly dull will still cut 50 mm sheet cleanly while producing a taper on 1 mm sheet.

The table and the fence need to be flat and square. Foam dust under a block, or a chip on the table, shows up as a thin patch in the sheet directly above it. Clean the table surface at every block change, not once a week.

• Every shift: blade edge, table surface and fence, dust at the head.
• Weekly: blade tension, guide clearance, drive and feed condition.
• Monthly: lubrication, electrical cabinet dust, thickness check against a gauge.
• After a blade change: re-set the guide and cut one measured test block.

The machine ships in an export plywood case with the head blocked and the table protected. At 8300*6200*2500 mm and 6000 kg, plan the container loading and confirm the door width at the destination before the freight booking.

Delivery is 45 working days after downpayment, payment by T/T or L/C, minimum order one set. Installation guidance, remote commissioning support and spare blades can be supplied with the machine.
