This project for military and aerospace cooling and ventilation applications was completed using a fairly simple manufacturing process with a minimal number of operations. This allowed us to keep costs low for our client. However, it required some unique forming capabilities and a high level of attention to detail to meet strict design requirements.

We used 0.0478” ±0.004” thick soft-tempered cold-rolled sheet steel and applied blanking to the flat contour of the part. Next, the sides were form drawn and re-hit to hold a 90-degree angle. And finally, eight small holes and one center opening were punched. Each part received light sanding to finish. All processes (except the sanding) were done on a punch press with universal tooling.

Dimensional inspections of the part ensured that the customer-supplied design specifications were met. The final products measured 6.000” long x 6.350” wide x 0.250” high and weighed 7.4 oz.

Leveraging our streamlined manufacturing process, we delivered 100 blower covers to our client in the Eastern US in just three weeks.
