Product Description
The 1A1B low-pressure foaming machine is a dedicated system for producing polyurethane foam from a single polyol (A) and a single isocyanate (B). Operating under low pressure (typically below 10 bar), it ensures stable injection, thorough mixing, and uniform curing in molds. This machine is ideal for standardized, medium-to-high volume production where recipe simplicity, operational reliability, and cost efficiency are key.
Key Features
Accurate & Stable Metering System
Features two high-precision metering pumps (one for A component, one for B) with closed-loop flow control.
Delivers consistent metering accuracy within ±1%, ensuring optimal A:B ratio and preventing common defects like density variation or weak spots.
Simple, robust design minimizes calibration needs and supports long-term ratio stability.
High Mixing Uniformity
Low-pressure mixing head with optimized internal geometry ensures complete and homogeneous material blending.
Achieves >98% mixing uniformity, producing foam with consistent cell structure, texture, and physical properties batch after batch.
User-Friendly Operation
Intuitive 7-inch color touchscreen interface allows easy setup and monitoring of flow, ratio, temperature, and timing parameters.
Integrated fault diagnostics and clear alarm messaging help operators quickly identify and resolve issues, maximizing uptime.
Energy & Cost Efficient
Low-pressure operation reduces energy consumption by 25–30% compared to conventional high-pressure systems.
Efficient thermal design and quality insulation minimize heat loss, lowering ongoing operational expenses.
