The manufacturer contacted Seglian to see if we could help. We already had established, capable, and competitive manufacturers of investment castings, so our main focus was on the precision stainless steel tubes and casing assemblies. The precision tubes were very tight tolerance, very thin wall, and needed to be 100% pressure tested. They were also very high annual quantity. This was not your average tube mill set up.
Precision tubes. After some searching and evaluation, we partnered with a manufacturer of rabbit ear antennas. The existing tube mills were just the right size and accuracy we needed, and the supplier could meet our required volumes. We worked with the factory to improve some systems, and add some processes and machinery. We were in production in the needed six-month time window.
Case assemblies. For the case assemblies, we partnered with a supplier making stainless steel cold drawn tubing as the basic component of the assembly. We installed the required presses and machining equipment, built the welding fixtures, and submitted our PPAP 5 months after we began.
For later generations of the precision gas tubes, we further developed the process and custom designed machinery to add spiral corrugations in the tube to increase turbulation and heat transfer, increasing the efficiency of our customer’s product.
