Now our company prepares "hot rolled high precision copper strip" for global transformer buyers}1000ton(15mm5Width≤1400mm:0.2mmSThickness
≤3.0m 500 tons of high conductivity aluminum strip for export (15mm≤Width≤1600mm;0.15mm≤Thickness≤3.0mm).
Ithas two production bases, eight sets of production and processing equipment,foursets ofindependent chamfering equipment,and two industry-cer-tified inspection rooms. Each batch of products will undergo 17 process inspections before becoming finished products
Check the raw material foill, electrical conductivity and hardness index.In the process of slitting, deburring and other processes, ensure that the indica-tors and parameters of the product meet the user's requirements.
