Approach B - "Cast-In" Steel Tube

Steel Tube2.jpg (16767 bytes)

In this approach, the steel tube is positioned in the mold and the component is cast directly around the tube.

  • The steel tube is carefully cleaned prior to casting.

  • The tube is precisely positioned in the mold

  • The solidification shrinkage of the casting provides a strong clamping force between the tube and the casting

The "Cast-In" approach gives a strong, precise, reliable shrink/mechanical fit between the tube and the casting with no machining or fitting costs.

The "Cast-In" steel tube is a good joining approach.
