Multi-component high-pressure mixing head

Seating is one of the most important and critical components in a vehicle, requiring a combination of high performance and styling. In fact, its finish and comfort define the car quality; its long-term performance and durability determine customer satisfaction. With the main targets being to reduce manufacturing costs and improve quality and properties of the foamed products under a range of climatic conditions, carmakers are defining highly sophisticated seating specifications to increase production flexibility and enhance environmental compatibility.

Cannon AX Multi-Component High-Pressure Mixing Head

Cannon AX was particularly developed for the production of flexible foam parts with hot and cold cure moulding requires multi-component formulations and also tipically for automotive seating and furniture foams applications. In the AX mixing head, four components can be injected radially into the mixing chamber and re-circulated at high-pressure along the four grooves carved into the mixing chamber cleaning piston prior to foaming.

Either Isocyanates or low-output compatible components (water, silicon, catalysts, etc.) can also be injected axially through the hole bored into the length of the mixing chamber closing piston. It is worth noting how the axially injected compatible components also re-circulate directly into the head, ensuring excellent output, pressure stability on injection phase and a superior mixing efficiency.

In particular, it is important to consider how TDI-based, MDI-based or blends of both Isocyanates (TM or MT) can be injected through the axial stream at pressures as low as 20 bar, with highly satisfactory mixing results and great simplification of the ISO-feeding circuit.
