High Pressure Polyurethane Foam Injection I Type Mixing head For Two components Polyol and ISO Key Components A typical mixing head typically consists of the following: · Valve body: The main structure with precise internal flow channels. · Piston/needle valve: The core operating component. · Drive unit: The air or hydraulic cylinder that powers the piston/needle valve. · Nozzle: The key component that determines material flow rate and mixing energy, often interchangeable to

Mixing head Introduction: The mixing head of a polyurethane high-pressure foaming machine is a precision component. Its core function is to instantly, intensely, and evenly mix components such as isocyanate (ISO, commonly known as black material) and polyol (POLY, commonly known as white material) under extremely high pressure. This mixing head then injects the components into the mold, triggering a chemical reaction that produces polyurethane foam. The design of the mixing

High Pressure Polyurethane Foam Injection L Type Mixing head Principle: High-Pressure Collision Mixing This technology is completely different from the mechanical stirring mixing principle used in low-pressure foaming machines. Its core is self-cleaning, high-pressure collision mixing. 1. High-Pressure Pumping: The main pump pressurizes the ISO and POLY components to very high levels (typically between 100-200 bar). 2. Circulation: During the non-injection phase, the
