Straight-through drawing

The flexible, productive pre-drawing of tubes from copper or copper alloys is possible thanks to the cascade principle used by SMS. Thanks to the better forming conditions of the straight drawing process you can minimize the tube eccentricity, achive closer tolerances and reduce handling between drawing stages. Depending on production requirements, the cascades can be implemented as single, double or triple-line arrangements with floating mandrels.

Appropriate to the production capacity you require, the drawing units can be designed as:

  • Conventional two-carriage drawing units
  • Caterpillar drawing units
