Sistema de dos componentes
Focusing on precise metering and efficient mixing of A/B materials, it offers easy operation and low maintenance, making it suitable for conventional processes such as polyurethane casting and filling. Compared to three-component high-pressure presses, it offers a more compact structure and lower investment. Unlike cyclopentane high-pressure presses, it does not require an explosion-proof system, making operation safer and less stressful. It is an ideal choice for small and medium-sized production capacities and multi-scenario applications.
Serie ciclopentano
The cyclopentane high pressure foam machine is a foaming machine specifically designed for the refrigerator, freezer, and insulated box industries. It is suitable for use with blowing agent systems such as cyclopentane and isopentane. Because cyclopentane is flammable, the equipment is designed with safety features such as an explosion-proof system, nitrogen protection, and explosion venting devices to ensure efficient and safe production.

Accesorios principales de la máquina de espuma de PU de alta presión
L type mixing head
Made of high-strength alloy steel, the channels are precision-ground, making it suitable for casting in molds with limited space. With a mixing ratio accuracy of ≤±0.5%, it can consistently perform over 500,000 castings.
L type mixing head
The symmetrical “T”-shaped injection structure and mirror-polished channels ensure more uniform mixing. With a mixing ratio accuracy of ≤±0.3%, it can consistently perform over 500,000 castings even in high-frequency continuous production.
Flow meter
Featuring a high-precision gear design and a wear-resistant alloy steel housing, it achieves a metering accuracy of ±0.2%. It offers high repeatability and stability, maintaining precise metering even under high viscosity and fluctuating temperature conditions.
metering pump
Utilizing hardened stainless steel and precision-ground gears, it is wear-resistant and corrosion-resistant. With a flow range of 0.3–300 L/min and a proportional error of less than ±0.5%, it enables long-term continuous operation. Its stable pressure output makes it suitable for high-pressure and high-speed casting.

Large Component Foam Press Applications
Large parts change what a high pressure foaming line has to do. When a coldroom panel, a garage door leaf or a long decorative cornice is foamed, the reacting mix expands across a wide area at once, and without restraint the part bows, the skin ripples and thickness drifts from one end to the other. That is why large components are foamed in a foam press: the mould sits in a press-type mould carrier that clamps the part flat and holds it dimensionally stable through the whole rise and cure, then releases it as a finished panel or profile.
The large component work this machine is built for:
- Coldroom and sandwich panels – continuous large-format boards where core density has to stay even over several cuadrado metres of surface.
- Garage doors – a full door leaf foamed in one shot, with the press keeping the steel skins parallel so the panel stays flat after demoulding.
- Decorative cornices and mouldings – long slender parts where the press guarantees a straight, sharp profile along the full length.
High-pressure foam (HF) metering is what makes this repeatable on big shots. A high-flow mixing head plus accurate metering pumps deliver a large volume in a short, controlled shot, so the polyol and isocyanate stay on ratio from the first second to the last and the mix reaches the far corners of the mould before the cream time ends. The result on large components is uniform density across the whole area, a smooth closed surface and shot-to-shot consistency that PLC control records and repeats.
