Metal Door with PU filling
This week we have 1x40' container for loading in our factory, and the metal doors are filled with PU material and the style is 6 panel, 2 panel with oval glass, 4 panel with half moon glass. In fact, the PU door production is not very complex when you have chance to see the process. Here i just show you the doors with pu after production. And you can see the injection holes for PU.
I think, some people do not know this filling material, and most company would not produce this kind of doors, because if the production is not steady and there are many failed doors. So the production cost is high and meanwhile, if the steel sheet is not right, there are also some problems after enjecting the PU, for example, there are dents on the door surface. PU, short. for polyuretha, which used very popular in life as you see. TwinkleSteel can do the suitable skin.
