We received a request for a Tritan oval tube that would be used as a robotic casing.
The challenge was that the tube had to fit within the wall grooves of a machined cap. Rectangular tubing, due to the extrusion process can develop stresses along its major axis. Sometimes the wall can thin at the center of the major axis while thickening on the minor axis.
In our first attempts, we found the usual thickening near the minor axis and went to work on a new vacuum sizer.
