High-Pressure PU Foaming Machine Precision Mixing Head 240 Bar Output 300kg Per Minute

This high-pressure PU foaming machine is built around a precision mixing head that impinges the two components at up to 240 bar inside a small chamber, producing a very fine and uniform cell structure without mechanical stirring. The head uses ceramic nozzles and a hardened needle, so wear is slow and the mixing quality stays stable across millions of shots. Output reaches 300 kilograms per minute, which makes the unit suitable for large blocks, rigid panels and continuous panel lines where the pour must keep pace with the conveyor. The hydraulic unit is a variable displacement pump with proportional control, giving smooth pressure ramp up and short cleaning cycles. Because high pressure machines handle filled systems better than low pressure designs, the customer can run calcium carbonate filled polyol and flame retardant packages without frequent nozzle clogging. The head is mounted on a swinging arm with a pour programmer, so the operator can set a shot pattern and let the machine repeat it exactly for every block. Pressure, temperature and ratio are displayed continuously, and alarm limits are configurable for each recipe.

• Precision Impingement Head: The 240 bar mixing chamber with ceramic nozzles produces a fine, even cell structure and holds mixing quality over a long service life.
• High Output Capability: At 300 kilograms per minute the machine keeps up with wide blocks and continuous panel lines, avoiding slow pours that cause density bands.
• Filled System Friendly: High pressure impingement handles calcium carbonate and flame retardant filled polyol without the clogging problems typical of low pressure agitator heads.
• Programmable Pour Pattern: A swinging arm and pour programmer record the shot path, so every block receives the same pattern and the operator does not rely on hand timing.
• Proportional Hydraulics: Variable displacement pumps with proportional valves give smooth pressure ramps, short cleaning cycles and lower hydraulic oil temperature during long shifts.
• Live Ratio Monitoring: Pressure, temperature and component ratio are shown on screen with configurable alarm limits, so drifting ratio is caught before a block is wasted.

Typical users are plants making rigid PU panels, insulated sandwich elements, refrigerator cabinets and technical flexible foam. The machine also serves moulded foam producers who need short cycle shots with a repeatable pattern. Because filled systems run reliably, the same unit supports cost optimised formulations that would quickly block a low pressure agitator head. Customers who later add a second head or a robot can reuse the hydraulic power pack, which protects the initial investment and keeps the footprint of the foam shop unchanged.

The mixing head is shipped in a separate foam lined case to protect the ceramic nozzles, while the tanks and frame travel on a steel skid inside a 40HQ container. Pressure test reports and material certificates are included with the shipment. The warranty runs for twelve months on the hydraulic unit and head body, and the service team supplies a spare nozzle set with every order so production never waits for an overseas delivery. Installation and commissioning support is available on site or through a live video session with the commissioning engineer.
