3000 kg/h Continuous Foaming Machine for 1.2-1.5 m Cylinder PU Foam Blocks

The TDP-1500 is a vertical cylinder continuous foaming machine. Foaming diameter is 1.2-1.5 m, production capacity is 3000 kg/h, foaming flow is 90 L/min, density range is 8-50 kg/m³, total power is 56 kW and machine weight is 12000 kg. The machine is CE certified.

Capacity is where a foaming line is won or lost. A line that pours 2000 kg/h cannot keep a peeler and two slicers busy, so the peelers wait and the labour cost per sheet climbs. The TDP-1500 is set at 3000 kg/h with a 90 L/min flow, which is the point where one pouring station feeds a full mattress foam line without a second shift.

Output is not only the pump size. The lifting table has to rise at a rate that matches the pour, the rotation speed has to hold the block round, and the trough and fall plate have to stay at temperature through a long run. On the TDP-1500 the lift speed and rotation are set from the PLC panel, so the 3000 kg/h figure repeats block after block instead of drifting with the operator.

• Model: TDP-1500
• Output: 3000 kg/h
• Foaming diameter: ⌀1.2-1.5 m
• Foaming flow: 90 L/min
• Density range: 8-50 kg/m³
• Total power: 56 kW

1. Set the recipe. Store the density and chemical ratio for the block being poured.
2. Set the lift speed. Match the 90 L/min flow so the block rises at the rate the pour fills it.
3. Start the rotation. Hold 3000-5000 rpm so the block stays round along its full height.
4. Pour and follow. Let the head follow the lifting table while the block builds.
5. Cut off at height. Stop the pour at the target block height and let the block cure.
6. Release and weigh. Check block weight against the density target before peeling.

Weigh the first block of every recipe against the density target. A 5% weight drift is easier to correct at the panel than at the peeler.

A line running at 2000 kg/h leaves the peeler idle between blocks. The operator uses that gap to handle the block, which is exactly the labour the machine was bought to remove. At 3000 kg/h the pour outruns block handling, so the peeler stays loaded and the sheet cost drops with the same crew.

The second gain is scheduling. With 3000 kg/h, a customer order that used to need two production days fits into one, and small runs can be grouped without changing the recipe. That is what makes a cylinder foaming line viable for mixed orders rather than one standard density.

The third gain is waste. A 1.2-1.5 m cylinder block peels into sheets with a predictable core loss. The bigger the block against the same sheet size, the lower that loss spreads across the tonnage, and the 3000 kg/h output is what makes the bigger block worth pouring.

• Output: one station feeds a peeler plus slicers without a second shift.
• Repeatability: PLC lift and rotation settings repeat on every block.
• Waste: 1.2-1.5 m blocks spread the core loss over more sheet tonnage.

• Continuous pour: the head follows the lifting table so blocks follow one another without a batch change.
• 3000 kg/h output: matches the peeling and slicing capacity of a mid-size mattress foam line.
• 8-50 kg/m³ window: one machine covers soft, medium and high density recipes by changing the metering recipe.
• ⌀1.2-1.5 m blocks: the cylinder diameter keeps peel waste low when blocks are converted into thin sheets.
• PLC control: lift speed and rotation speed are set from the panel and repeat on the next block.
• Low labour demand: two operators can run the pouring station once the recipe is set.
• CE certified: export-ready guarding and electrics.

• Mattress foam plants: cylinder blocks poured for peeling into mattress and topper sheets.
• Furniture foam: sofa and cushion foam blocks in medium and high density.
• Shoe material foam: soft foam blocks for insole and lining stock.
• Bra and garment padding: low density soft foam for padding stock.
• Electronics packaging: protective foam blocks cut into inserts.
• Automobile interior: seat and trim foam blocks poured in the same line.

• Lock out the foaming head before any nozzle or trough work.
• Keep the lifting table zone clear while the pour is running.
• Vent the foaming room and monitor isocyanate exposure.
• Follow the pressure relief sequence before opening any chemical line.

• Flush the mixing head at the end of every shift.
• Check the metering pump seals weekly for weeping.
• Inspect the lifting chain and guides monthly.
• Keep the PLC recipe backup in the maintenance file.

The machine travels in an export-grade wooden case with the electrics protected and the cutter or blade assembly braced separately. Machine weight is 12000 kg and the overall dimension is 4000*6000*8500 mm, so the unit is quoted against a 20ft or 40ft container depending on the line it ships with.

A packing list, wiring diagram, operation manual and CE declaration travel with every unit. Delivery is 45 working days after downpayment; installation and commissioning support is available remotely or on site.
