The manufacturer was originally using a piece of cut tubing as a spacer used to support two plates in an automotive front-end assembly. The tubing was cut to the proper length, placed between the two plates and then welded in place.
Due to the fact that a 16mm bolt was passed through the inside diameter of the tubing, the inside diameter needed to be burr free. In the process of cutting the tubing to length, a burr was left on the inside diameter and therefore, in order to meet the quality requirements, a secondary operation of deburring was needed, adding a great deal of cost to the cut tubing.
SPIROL recommended a standard, butted-seam spacer to replace the cut tubing in this application. These roll-formed spacers have clean cut, square ends and therefore no secondary operations are required to ensure a burr free part. As this was an automotive application, the Spirol spacer had to undergo numerous tests to ensure the strength would meet the requirements previously set.

“By recommending a butted seam, roll-formed spacer for this application, the customer was able to save a significant amount of money. The cost of the cut tubing (with the secondary deburring operation) was 0.37 euros per piece. The price for the butted-seam Spirol spacer was 0.13 euros per piece, resulting in overall savings of 160,000 euros per year.”
