Copper-Clad Aluminum & Steel Conduit Annealing Machines
Tubular annealing for 24–40 head CCA and CCS lines.
Six CCA configurations from Φ3.0 mm inlet to Φ0.08 mm outlet.
Copper-clad aluminium needs gentler capstan surfaces and controlled slip to protect the copper layer. The 24DL, 24DL-A/B, 14DL, 17MD and 20D use ceramic or tungsten-carbide capstans, spray lubrication and matched annealing for consistent CCA wire.
