Investment Casting Case Studies |
|
|
| |
 |
The combustor assembly is a critical part of the microturbine power generator for the Parallon 75. |
|
The original component consisted of 16 individual machined tabs that were electron beam-welded in 64 places onto a fabricated tube. With direct responsibility and considerable input into the design of the new combustor assembly, consolidated Casting Corp. redesigned the tabs as a single ring casting in which two rings are cast at once. |
|
Each finished ring component is butt-welded into a 0.080 in. wall sheet metal tube, as opposed to the individually welded tabs of the original design. |
|
The foundry also assembles the complete combustor assembly, which includes five investment castings, sheet metal tubes, a machined pin, stampings, tubes and fittings. |
|
The change in design reduced the sub-assembly time by 26 minutes and achieved a greater than 50% per-part cost reduction. | |
