Extraction Hood Used in Air Purification Systems

With over 30 years of experience in metal spinning, at Metcom Engineering our expertise is sought after to provide high quality spun products at competitive prices. In the project highlighted here, a customer in the air purification industry commissioned us to manufacture a custom extraction hood. This component acts to draw out airborne contaminants for filtration and is a critical element of their air purification system. In addition to our world class metal spinning techniques, several production processes were employed to complete the hood to customer specifications including laser cutting, trimming, and hole piercing. The hood was constructed from aluminum, which was manipulated with our state of the art equipment including our Omera trimming machine, spinning lathe, and horn press. To aid in rapid and precise hole punching, we devised special location indicators to mark their exact spots. Throughout production, systematic quality management protocols and in-process micrometer inspections confirmed dimensional accuracy. The completed hood was cleansed of residue and left with a natural finish.

Overall measurements of the extraction hood were 13″ in diameter and 8.5″ in length. We were able to achieve the tightest tolerances of ± .015″ for the diameter and ±.030″ for length. Annual production volumes of this part range from 100 to 200, with a normal lead time of 2.5 to 3 weeks. The customer was very pleased with our workmanship and rapid turnaround time, and has extended our relationship with additional projects.
