Tooling, Fixtures, Dies & Mold Economics worked example

Tooling Capacity at 65% tooling availability: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop tooling availability to 65%, then walk the calculation through step by step. Estimate tooling capacity for tooling, fixtures, dies and mold economics using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Parts per tooling cycle: 4 units / cycle (held at the documented default)
  • Available tooling cycles in period: 480 cycles (held at the documented default)
  • Tooling availability (uptime): 65 % (the input this scenario stresses; the baseline uses 90)
  • Tooling first-pass yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross tooling capacity = tooling capacity output per cycle × available tooling capacity cycles.
  • Good tooling capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross tooling capacity works out to 1,920 units at these inputs.
  • Tooling capacity downtime loss works out to 672 units at these inputs.
  • Tooling capacity yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where tooling availability sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to tooling availability, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It uses period-average availability and yield; it does not model peak-demand bottlenecks, changeover time between jobs, or a single tool shared across multiple part numbers.

Results at a glance

  • Good tooling capacity: 1,211 units (headline result)
  • Gross tooling capacity: 1,920 units
  • Tooling capacity downtime loss: 672 units
  • Tooling capacity yield loss: 37.44 units
