Descripción del producto
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.
Características principales
Precise & Flexible Metering System
Equipped with three high-precision metering pumps (two for A components, one for B) and closed-loop flow control.
Metering accuracy within ±1%, ensuring correct A1:A2:B ratios and preventing defects such as uneven density or weak structure.
Supports quick switching between two A-component formulations, ideal for dual-color, dual-density, or dual-hardness products.
Excellent Mixing Uniformity
Low-pressure mixing head with optimized internal flow channels and shear design ensures thorough raw material integration.
Achieves >98% mixing uniformity even with varying viscosities, resulting in consistent cell structure and physical properties.
Easy Operation & Smart Control
User-friendly interface with 7-inch color touchscreen for intuitive parameter setup (flow rates, ratios, temperature, timers).
Built-in fault diagnostics and alarm system to minimize downtime and simplify troubleshooting.
Energy-Efficient Design
Low-pressure operation reduces energy consumption by up to 30% compared to high-pressure systems.
Efficient thermal management and insulation minimize heat loss, lowering long-term production costs.
