Moulded polyurethane foam is the standard for automotive, motorcycle and furniture seat cushions. The key equipment decision is whether to run a high-pressure or a low-pressure foaming machine. As a manufacturer of both, we compare them for seat foam production below.
| Factor | High-Pressure Machine | Low-Pressure Machine |
|---|---|---|
| Output | High, continuous lines | Medium, batch/flexible |
| Mixing head | Self-cleaning (no solvent) | Mechanical (solvent flush) |
| Formula/colour changes | Slower | Fast, frequent changes |
| Waste & running cost | Lower per part at volume | Higher solvent use |
| Investment | Higher | Lower |
| Best for | High-volume OEM seat lines | Small batches, varied products |
How to Choose
Choose a high-pressure machine if you run high-volume automotive seat lines and want low waste and a self-cleaning mixing head. Choose a low-pressure machine if you make smaller batches, change formulas and colours often, or want a lower initial investment. Many seat makers start low-pressure and add high-pressure as volume grows. See our car seat foaming solution.
FAQ
Which is better for car seat foam?
High pressure suits high-volume OEM lines with low waste; low pressure suits smaller batches and frequent formula or colour changes. The best choice depends on your output and product mix.
Can one line make car, motorcycle and furniture seats?
Yes. The same foaming machine feeds different moulds, so changing the mould lets you produce different seat types.
Do you supply the PU material?
No — we build the machine and moulds. You run them with your own or sourced polyol and isocyanate system.
