High-pressure series
High-pressure PU foaming machine
Adjustable 6–20 MPa injection pressure, 100–300 g/s standard output and a V-type self-cleaning mixing head.
Separate pumps meter polyol and isocyanate. The streams meet at high speed inside the mixing chamber. The V-type head uses impact mixing and requires no solvent flush.
Share the material system, mixing ratio and required shot weight to review the operating point. Flexible, rigid and semi-rigid foam applications require configuration confirmation.

Mixing, metering and controls
- V-type mixing head — Impact mixing with a self-cleaning head that requires no solvent flush.
- Plunger metering pumps — Variable-frequency drives adjust pump displacement. The protection system can stop the machine and raise an alarm.
- Process controls — Siemens PLC and WEINTEK touch screen with recipe storage and configurable filling channels.
- Slot-type filters — 300 µm filtration on the polyol side and 200 µm on the isocyanate side.
- Pneumatic feed pump — The isocyanate side uses a pneumatic diaphragm pump with a PTFE/F46 diaphragm.

Can the machine process a cyclopentane formulation?
Cyclopentane configurations can be reviewed. Share the material specification, site requirements and applicable safety requirements so the manufacturing partner can confirm suitability.
Can the machine feed multiple mixing heads?
Multi-head arrangements can be reviewed for suitable line configurations. Share the number of heads, mould layout and operating sequence.
What utilities and space should I allow?
Start with the standard machine specifications above. Confirm electrical supply, dry compressed air, cooling requirements and service clearance for the selected configuration.
