Polyurethane spray foam machine is the best choice for exterior and interior wall insulation, allowing for a seamless connection between insulation layers, high insulation performance, and strong adhesion. Our polyurethane spraying machines are suitable for various insulation projects, including residential buildings, factories, cold storage exterior walls, and steel structure buildings.

Advantages of wall insulation spraying

High-Efficiency Construction


Automatic mixing and continuous spraying improve construction efficiency; one machine can spray 300-500㎡ per day.

Integrated Insulation


Polyurethane foam adheres directly to the wall, eliminating the need for additional panels.

Sound Insulation and Moisture Proof

Closed-cell foam structure effectively prevents condensation and noise transmission, extending the lifespan of the wall.

Long Lifespan

Core components are wear-resistant and corrosion-resistant; the machine can operate continuously for many years and is easy to maintain.

Customizable Voltage

220V or 380V versions can be customized according to the construction site.

  • Our polyurethane tank insulation spray coating uses a high closed-cell formula with a closed-cell rate of over 90% and a thermal conductivity as low as 0.022 W/(m·K). This allows it to quickly form a dense, seamless insulation layer on the tank surface, significantly reducing heat loss.
  • The material has a controllable expansion ratio and strong adhesion (≥ 0.3 MPa), maintaining uniform foaming on vertical, horizontal, and large curved tank surfaces without sagging or collapsing.
  • The material has a temperature resistance range of -40℃ to 120℃, is resistant to aging, waterproof, and corrosion-resistant, and maintains stable insulation performance even after long-term use.
  • We also offer customized formulas to better suit customer temperature requirements, construction environments, and tank types, resulting in more efficient and durable insulation.

PU Spray foam machine wall insulation Success Stories

A Mexican company undertook the wall insulation project for a 1,200㎡ industrial building, requiring an 8cm thick polyurethane insulation layer. The client had previously used traditional panel construction, which resulted in long construction periods and inconsistent insulation performance.

After adopting our 2–12 kg/min flow rate polyurethane sprayer, only 60m of piping was needed to cover the entire wall, and the entire project was completed in 2 days.

The client was extremely satisfied with the construction efficiency, insulation quality, and equipment stability, and currently plans to use our sprayers and materials long-term in other projects.

During mass production, the high-pressure machine ensures uniform foam density, stable flow rate, and no voids in the corners , meeting the customer’s high standards for comfort and safety. Thanks to Yongjia’s solution, the production capacity of the entire production line has increased by more than 30% , and the reject rate has dropped to below 2% , greatly reducing operating costs.

The customer feedback indicates that Yongjia’s high-pressure machine has extremely low failure rate and simple maintenance during long-term operation, not only improving production efficiency but also enhancing the competitiveness of the product in the international automotive seat market.

Using this polyurethane spraying machine, we completed 1,200 square meters of wall insulation in just two days, three times faster than traditional methods. The foam density was stable, the foaming was uniform, completely seamless, and the overall insulation effect was excellent. We plan to continue using this equipment and materials in all our projects.
