Industrial Fans, Blowers & Air Movement Equipment calculator

Sheet Metal Housing Yield Calculator

Use this calculator to measure yield for fan housings and blower casings. It helps production and quality teams see whether formed panels, scroll housings, inlet cones, outlet flanges, weldments, and guards are passing without rework.

What this calculator does

  • Calculate first-pass sheet metal housing yield from accepted housings, fabricated housings, and target yield.
  • Use it when tracking housing fabrication, welding, grinding, leak checks, fit-up, paint readiness, or scrap performance.
  • The result shows first-pass yield for fan housings or blower casings.

Formula used

  • Sheet metal housing yield = accepted fan housings first pass ÷ total housings fabricated × 100
  • Housing yield gap to target = sheet metal housing yield - target housing first-pass yield

Inputs explained

  • Accepted fan housings first pass: Count housings or casings accepted without major weld repair, refit, rework, scrap, or dimensional correction.
  • Total housings fabricated: Use the total fan housings, blower casings, scrolls, or sheet metal assemblies completed in the period.
  • Target housing first-pass yield: Enter the plant target, customer requirement, or launch target for sheet metal housing yield.

How to use the result

  • Use it to prioritize weld quality, forming accuracy, fixture improvement, scrap reduction, and rework control.
  • It depends on consistent acceptance criteria and whether minor cosmetic corrections are counted as rework.

Common questions

  • What is the sheet metal housing yield calculator for? It calculates first-pass yield for sheet metal fan housings or blower casings.
  • What information should I enter? Use accepted first-pass housings, total fabricated housings, and target yield.
  • What does the result tell me? The result helps identify fabrication, welding, fit-up, or scrap issues.
  • When is the result only an estimate? It is only an estimate when acceptance criteria, product mix, or rework definitions change.
