High Pressure PU Foaming Injection Machine

The High Pressure PU Foaming Injection Machine is a core unit of the sandwich panel production line, designed to deliver precise metering and stable mixing of polyurethane components under high pressure.
The system adopts advanced high-pressure impingement mixing technology to ensure uniform cell structure, consistent foam density, and excellent bonding performance.

To guarantee stable foaming quality, the machine is equipped with an integrated raw material conditioning system, including precise temperature control and continuous material circulation. This ensures that polyol and isocyanate are maintained at optimal processing temperatures, even during long-term continuous operation.

Controlled by a PLC and high-precision metering pumps, the machine allows accurate adjustment of injection ratio, output, and foaming parameters via the touch screen interface. With fast response, low material loss, and excellent repeatability, the system is ideally suited for high-speed, high-quality sandwich panel production.
