The fully automatic production line of volume control damper produced by our company is a self-developed high-efficiency fully automatic
production line on the basis of fully absorbing the advanced experience of industry-leading companies and aiming at the slow
efficiency of previous fire damper manufacturers. It adopts new riveting technology, which effectively solves many problems caused by the out-of-date welding process. The whole vcd frame has no welding spot, no anti-rust treatment, and maintains the original galvanized layer of the zinc plate with a beautiful appearance. The entire line is standardized, intelligent, and highly efficient.
