Quality Control of Dongguan Spiral Duct Forming Process
Dongguan spiral air pipe
fittings (pipes and joints) production has been highly automated, systematic, and has industrial quality control. The installation time of the spiral duct system is only 1/3 of the similar rectangular duct.
Pressure reduction: As we all know, the wind resistance of spiral duct is much smaller than that of rectangular duct.
The precise bite forming process of the Dongguan spiral duct
: the molds used in the imported equipment are all special steel structures. Even after three or five years of use, the surface of the pressing mold remains unchanged, so that the surface of the galvanized steel sheet is not damaged , Greatly extending the service life of the spiral duct, at the same time, the joints are even and flat, the mouth is tight, the connection is strong, and the seal is good.
