The Profiltech Milling Process

The Profiltech milling process

All copper materials can be milled in all conditions. Our milling process does not introduce stresses into the material. The microstructure of the base material is thus not impacted.

Milling in no way affects the homogeneity of tensile strength, hardness, electrical or thermal conductivity over the profile width. Unlike other processes, milling does not change the microstructure of the base material.

The great design freedom of the cross-section allows a flexible design of the thickness transitions (flank angle, radii). Furthermore, the milling process allows close thickness tolerances to be achieved in longitudinal and transverse direction.

Less strip consumption per punched part
Low tool costs, as folding and embossing are not required during the punching process
Smaller tools and presses; shorter set-up and maintenance times
Higher productivity during punching, as higher punching speeds are possible
No readjustment of the punching parameters at coil changes

Technological properties

Depending on the condition of the starting material – flatness, coil set, camber, cutting quality – and the milling geometry, stresses can be released during milling. These can influence the twist, cross bow and camber. In many cases, levelling before or during milling will improve these values.
