Its disadvantage is that the PU material pours on both sidesrepeatedly and wastefully. It is easy to mix a lot of bubbles during pouring. There are some defects in theproduct, such as bubble, different density distribution of core material and insufficient filling due to unevenpouring. According to years’ production experience and repeated adjustment of production process, thisspraying bar is developed by adopting fixed pouring method. By improving the defects of traditional foamspraying, the quality of sandwich panel can also be greatly improved
