2A1B Low Pressure Foaming Machine
Low Pressure Polyurethane Machine
The 2A1B low-pressure foaming machine is specialized equipment for producing polyurethane foam using two different polyols (A1, A2) and one isocyanate (B). Operating under low pressure (typically below 10 bar), it enables accurate injection, mixing, and curing in molds, making it suitable for multi-material formulations and medium-scale production runs where material flexibility and consistency are critical.
Key Features
- Precise & Flexible Metering System
- Excellent Mixing Uniformity
- Easy Operation & Smart Control
- Energy-Efficient Design
