Revealing the Core Technology: How a Pu Foam Spray Machine Works
The core of a pu spray machine is its high-pressure spray technology. It precisely measures and heats two liquid polyurethane components (A and B) inside the machine. These are then instantly mixed at high pressure within the spray gun. The atomized liquid is sprayed evenly onto the substrate. Within seconds, it rapidly foams and cures, forming a dense, continuous protective layer.

Pu Foam Spray Machine Key Technical Advantages:
- Efficient and Stable: Our polyurethane foam spray machine features an advanced pneumatic booster system with a very low failure rate. An advanced ventilation method ensures the equipment runs stably for extended periods.
- Powerful Performance: We use globally renowned brand AIRTAC for cylinders and solenoid valves, which provides powerful and durable performance.
- Clog Prevention: A unique four-stage material filtration system minimizes spray gun clogging, ensuring a smooth operation.
- Easy to Use: The latest spray gun model is compact, lightweight, and simple to operate, with a superior atomization effect. Even a beginner can quickly get the hang of it.
- Safety Assurance: A multi-layer leakage protection system fully guarantees the safety of the operator.
Pu Foam Spray Machine FAQ
A PU foam spray machine is mainly for spraying polyurethane foam, which is characterized by a high expansion ratio and excellent thermal insulation. A polyurea spray machine is for spraying polyurea materials, which have faster curing, higher strength, and better corrosion resistance. We can recommend the best machine for you based on your specific needs, such as insulation or waterproofing.
A pneumatic machine uses compressed air as its power source, making it simple to operate and easy to move. A hydraulic machine has an independent hydraulic station, providing more power and higher pressure, suitable for projects with high-pressure requirements. We offer both models so you can choose based on your budget and project needs.
We provide comprehensive after-sales service, including technical support, spare parts supply, and routine maintenance. Our professional team is always ready to assist you, ensuring your equipment stays in optimal working condition.
Pu Foam Spray Machine: Wide Applications and a Success Story
Polyurethane spray foam equipment is widely used across various industries. In construction, it’s used for insulation and waterproofing roofs, exterior walls, cold storage facilities, and granaries. In transportation, it’s applied for sound and thermal insulation in refrigerated trucks, ship cabins, and high-speed rail cars. It also has important applications in petrochemicals, automotive manufacturing, and other fields.
Case Study:
A client of ours in Mexico, who owns a cold storage construction company, faced a challenge. They needed an efficient and durable method to provide reliable insulation and sealing for large cold storage facilities. We recommended a custom-built polyurethane foam machine for sale and provided on-site technical training. By using our equipment, the client not only increased their construction efficiency by 30% but also achieved an excellent quality of insulation layer, which effectively reduced the energy consumption of the cold storage. The client said, “Using YG machinery’s equipment, our project progressed much faster, and our clients are very satisfied with the final insulation result. This polyurethane spraying machine is truly worth the investment!”
