Aluminum Extrusion Troubleshooting

Poor contour

Problem Description

The extruded profile does not accurately follow the intended contour, including radii, transitions, or surface geometry.

Cause–Correction Mapping
  • Feed into weld chamber unbalanced
    Cause in: Die

      Corrections

    • Open slow ports or restrict fast ports; streamline and balance weld chamber as required.

      Advantage: Achieve quality objectives.
