Feature
1. Accurate measurement: high-precision low-speed gear pump, the error is less than or equal to 0.5%.
2. Even mixing: The multi-tooth high shear mixing head is adopted, and the performance is reliable.
3. Pouring head: special mechanical seal is adopted to prevent air leakage and prevent material pouring.
4. Stable material temperature: The material tank adopts its own heating temperature control system, the temperature control is stable, and the error is less than or equal to 2C
5. The whole machine adopts 7-inch touch screen and PLC module control, which can pour regularly and quantitatively and automatically clean with air flushing.
Why PU Foaming Is the Eco-Friendly Choice for Wall Panels
Water-blown and CFC/HCFC-free
This low-pressure system runs on water-blown and low-GWP blowing agent formulations, so no ozone-depleting CFC or HCFC agents are needed in the panel foam. For importers in the EU and North America this is now a compliance gate rather than a selling point, and the machine is built to work with those formulations out of the box.
Metering error under 0.5% means less wasted chemical
The high-precision low-speed gear pump holds the metering error at 0.5% or less, and the material tank keeps component temperature stable within 2C. Accurate metering and stable temperature mean each panel is shot with the same amount of material, so overfill, short shots and trimmed-off scrap all stay low. Less scrap per panel is the most direct way a foaming machine reduces waste.
PU panels compared with PS panels and natural stone
If you are comparing PS (polystyrene) foam wall panel lines: PS panels are cheaper per square metre but PU integral-skin panels give sharper stone texture, better dimensional stability and a self-skinning surface without a separate coating step.
| Item | PU integral-skin panel | PS foam panel | Natural stone |
|---|---|---|---|
| Density | Low, foamed core with dense skin | Low | High |
| Transport weight | Light, one-person installation | Light | Heavy |
| Surface finish | Self-skinning, mould texture and colour in one shot | Needs a separate coating or facing step | Natural surface |
| Dimensional stability | Good, holds mould detail | Lower, softer edges | Not applicable |
| Process scrap | Low, metering error under 0.5% | Depends on cutting yield | High, quarry and cutting loss |
Panel weight is the other half of the footprint. PU faux stone is far lighter than natural stone, so a container carries more finished wall area for the same freight, and site handling needs no lifting equipment. If you need the moulding and demoulding stations as well as the foaming machine, see our complete PU panel production line.
Advantages Of PU Culture Stone
1. Mix the real with the fake
The mold is made of real stone, so even if the raw material is pressed and colored by the mold, it still has an uneven surface and a hard color like a stone, which is very realistic and can almost be faked.
2. Lightweight and durable
Don’t look at it like a stone, think it is as heavy as a stone, in fact, the pu stone is very light, and it can be installed by a single person! However, light weight does not mean that it is not strong, and the PU stone is resistant to acid, sunscreen and has a long service life.
3. Strong plasticity
As a new cross-border material, Pu stone has rich shapes and strong plasticity! Almost all cultural stone modeling pu stones are available.
4. Small security risks
Compared with the original ecological rubble, pu stone is not only light in weight, low in consumption, but also has much lower safety hazards. If you happen to be a stone lover, but are concerned about safety issues, pu stone is the best alternative.

FAQ
Can this machine make PS (polystyrene) wall panels?
No. This is a PU low-pressure foaming machine and it processes polyurethane systems only, not polystyrene. If you are evaluating PS panel lines, PU integral-skin panels are the alternative worth comparing: they carry sharper stone texture and come out of the mould already skinned, with no separate facing step.
Is PU foam wall panel production eco-friendly?
It can be. The machine runs water-blown and low-GWP systems with no CFC or HCFC blowing agents, and metering accuracy of 0.5% or better keeps chemical overuse and trimmed scrap low. The finished panels are also much lighter than natural stone, which cuts freight weight per square metre shipped.
Which model do I need for wall panel moulds?
It depends on the shot weight your panel mould needs. SPU-LS2-800 covers 200-800g per shot and suits small decorative panels. SPU-LS2-1200 covers 500-1500g for standard wall panels, and SPU-LS2-1800 covers 550-1800g for large-format or multi-cavity moulds. Send us your panel size and we will confirm the model.
Do you supply the panel moulds as well?
Yes. We make the stone-textured moulds in house from real stone masters, so the panel surface matches the original rock face. See our PU wall panel moulds range, or send your own sample for mould development.
