By using polyurethane to heat and pressure the black and white materials, a high-pressure impact is formed in the spray gun, resulting in a very thorough vortex mixing. The high-speed moving material forms fine mist droplets at the nozzle of the spray gun, which are evenly sprayed onto the surface of the object. The uniformity of mixing and atomization effect will affect it.

The entire polyurethane spraying system includes: host, spray gun, heating pipeline, feeding pump, connecting pipes between various components, spare parts, related tools, and air compressor (1m ³, 8kg pressure).

The flat pump polyurethane spraying machine can provide greater and more stable pressure, and is increasingly favored by major design departments. The perfect coaxial structure design of the flat type booster pump minimizes the wear of the sealing components, and there is no pressure difference during operation, with ideal and stable pressure fluctuations during directional changes; The high-speed circulation of lubricating fluid inside the anti solidification lubrication cylinder can quickly remove leaking raw materials or impurities, and the black material shaft is always immersed in the lubricating fluid to avoid crystallization.
