The mixing head is a precision component for polyurethane high-pressure foaming machines, engineered for instant, intense, and uniform mixing of isocyanate (ISO/black material) and polyol (POLY/white material) under extreme pressure conditions of 100-200 bar. This critical component ensures proper chemical reaction initiation for high-quality polyurethane foam production.

Unlike low-pressure mechanical stirring systems, this mixing head utilizes high-pressure collision mixing for superior performance:

• High-Pressure Pumping: Main pump pressurizes ISO and POLY components to 100-200 bar
• Continuous Circulation: Materials circulate through internal channels during non-injection phases to maintain stable temperature and properties
• Instant Injection Mixing: Actuator rapidly opens needle valve, allowing high-speed material jets (over 100 m/s) to collide in mixing chamber
• Self-Cleaning Action: Piston/needle valve returns to position after injection, scraping residual material to prevent cross-contamination and blockages

• Ensures uniform foam density and consistent cell structure
• Eliminates mechanical agitation for reduced maintenance
• Corrosion-resistant construction for extended service life
• Precision engineering minimizes defects in final polyurethane products
