16-wire drawing machine

Wire material

bare copper wire and tinned wire

Number of produced

wires

16 x copper bare i.e. copper tinned

(2 levels, each with 8 wires)

Inlet diameter

(tensile strength)

max. 16 x 1.80 mm (250 N/mm²)

Finishing diameter

16 x 0.15 0.40 mm  with the inlet diameter of 1.80 mm copper bare and tinned

16 x 0.10 0.20 mm with the inlet diameter of 1.40 mm cooper bare and tinned

Production efficiency

1st drawing die sequence with inlet diameter 1.80 mm

16 x 0.150                                        with v = 25.0 m/s

16 x                         - 0.203 mm     with v = 25.0 m/s

16 x                         - 0.250 mm     with v = 23.0 m/s

16 x                         - 0.300 mm     with v = 15.0 m/s

16 x                         - 0.320 mm     with v = 18.0 m/s

16 x                         - 0.360 mm     with v = 10.0 m/s

16 x                         - 0.400 mm     with v = 5.0 m/s

2nd drawing die sequence with inlet diameter 1.40 mm

16 x                        - 0.100 mm     with v = 22.0 m/s

16 x                        - 0.130 mm     with v = 28.0 m/s

16 x                        - 0.150 mm     with v = 28.0 m/s

16 x                        - 0.200 mm     with v = 15.5 m/s

Production efficiency for tinned wires at production speeds reduced by about 20%.

The above mentioned efficiencies are theoretic and show the possible efficiency of the offered drawing line. The actual production efficiencies are depending on different factors like quality of inlet wire, drawing dies, lubricant, spools, skill-fullness of the operator etc.
