0.5-70 mm Foam Slicing Machine ±0.05 mm Tolerance for 3000 mm Blocks

The TDB-2200 is a horizontal slicer for plants that cut many thicknesses from the same block. The range runs from 0.5 mm to 70 mm with ±0.05 mm tolerance on 0.5-2 mm sheet, cutting area is 3000*2200*1250 mm, main drive is 23 kW, machine weight is 6000 kg and overall size is 8300*6200*2500 mm.

A converter's problem is not the top thickness, it is the number of thicknesses. Every different sheet size is a different setting, and every setting change is a chance to make scrap. The TDB-2200 is designed so the change is a setting on the machine rather than a rebuild of it, and the block stays on the table while the order changes.

1. Finish the run. Slice the current block to the end of the order and clear the table.
2. Set the new thickness. Select the next value, 0.5 mm to 70 mm, on the machine control.
3. Check the block. Confirm the face is still square and the block is seated against the fence.
4. Cut a sample sheet. Take one sheet and measure both edges and the middle.
5. Run the order. If the sample is inside tolerance, continue without touching the setting.
6. Log the setting. Record thickness, foam grade and the measurement for the next repeat order.

The change is a setting, not a rebuild, which is why short runs of different thicknesses can follow each other on the same block instead of waiting for a setup slot.

The losses in foam conversion are usually not in the cut itself. They come from a block that was not square, a setting that was not recorded, or a sheet that was folded at take-off. Each of those turns a good block into second-grade stock, and on thin sheet the loss is invisible until the buyer measures it.

Recording the setting is the cheapest control available. If the batch log holds the foam grade, density, thickness, blade hours and the sample measurement, a repeat order starts from a known point instead of a guess. The same log tells you when a thickness complaint is a blade problem rather than a machine problem.

Handling matters more as the sheet gets thinner. A 0.5 mm sheet that is folded over the edge of a pallet is scrap, and no machine setting recovers it. Pallets at table height, a wide take-off route and a stack that stays flat are part of the process, not an afterthought.

• Square the block first: a sloped face produces a taper on every sheet cut from it.
• Log every setting: repeat orders should start from a known value, not a guess.
• Protect thin sheet: flat pallets at table height; never fold a sheet to move it.

• One machine, many sizes: 0.5 mm to 70 mm from the same block, which suits a converter's order book better than a single-purpose slicer.
• Long block slicing: a 3000 mm block runs end to end, so a batch of one thickness does not need reloading.
• Thin sheet accuracy: ±0.05 mm at 0.5-2 mm keeps comfort layers and lamination sheet inside the buyer's check.
• Wide table: 2200 mm cutting width means full mattress blocks are loaded whole.
• Stable head: the cut holds across the full width, so the far edge matches the near edge.
• 23 kW drive on a 6000 kg frame: feed rate is held through dense foam without vibration showing in the sheet.
• CE certified: export-ready guarding and electrics.

• Foam conversion: many sheet sizes from bought-in blocks.
• Mattress and furniture: comfort layers, backing and padding sheet.
• Packaging: protective sheet and inserts in mixed thicknesses.
• Lamination: uniform thin sheet for bonding lines.
• Acoustic and filter products: thin open-cell sheet at a fixed thickness.
• Trade and resale: sheet cut to a sellable thickness from stock blocks.

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.

With mixed orders, the discipline is in the paper as much as in the machine. Write the thickness, foam grade and block number on the order sheet before the block goes on the table, and check the first sheet against that number rather than against the previous run.

The machine is 8300*6200*2500 mm at 6000 kg, so the floor plan has to allow a loading route and a 2200 mm take-off route. Blocking the take-off side to save space is the fastest way to turn good sheet into creased scrap.

• Order sheet first: thickness, grade and block number recorded before cutting.
• Sample sheet: measured on every setting change, not once a shift.
• Guarding: head guard fitted, emergency stop reachable from the take-off position.
• Handling: lift or roller table for blocks, flat pallets for sheet.

Check the blade at the start of each shift and the guide clearance after every blade change. On mixed orders a slightly dull blade is easy to miss at 50 mm and obvious at 1 mm, so the first thin sheet of the day is the real test of the edge.

Keep the table and fence clean. Foam dust under a block produces a thin patch in the sheet directly above it, and on a mixed order that patch can end up in a customer's comfort layer.

• Every shift: blade edge, table and fence, dust at the head.
• Weekly: blade tension, guide clearance, feed system.
• Monthly: lubrication, cabinet check, thickness verification against a gauge.
• After a blade change: re-set the guide, then cut a measured sample sheet.

The machine ships in an export plywood case with the head blocked and the table protected. Confirm the container plan against 8300*6200*2500 mm and 6000 kg, and check the door width at the receiving site before booking freight.

Delivery is 45 working days after downpayment, payment by T/T or L/C, minimum order one set. Spare blades, guide parts and remote commissioning support ship with the machine.
