Anodize Seal Cost at 92% seal capacity utilization: a worked example

Push seal capacity utilization up to 92% and the picture changes. This example computes every intermediate figure at that operating point. Use it when costing the seal stage of an anodize line and you need to know its share of the finishing price per square foot.

The inputs for this scenario

  • Sealed Surface Area: 300 sq ft (unchanged)
  • Seal Cost per Square Foot: 0.42 $/sq ft (unchanged)
  • Seal Capacity Utilization: 92 % (raised for this scenario; the documented default is 80)
  • Tank Heat-Up Charge: 85 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total = sealed surface area x seal cost per sq ft x seal capacity utilization% + tank heat-up charge) to the inputs above produces each figure below.
  • At this operating point the engine returns 201 $ for total anodize seal cost, the number this scenario is built around.
  • At this operating point the engine returns 0.67 $ / piece for anodize seal cost per unit.
  • At this operating point the engine returns 116 $ for variable anodize seal cost.
  • At this operating point the engine returns 85 $ for fixed anodize seal cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where seal capacity utilization sits at 80% and the headline result is 186 $, this scenario comes in 8.14% above the baseline at 201 $.
  • It computes total seal cost as area times per-square-foot cost times tank utilization, plus a fixed heat-up charge, and gives cost per square foot. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
