Tooling, Fixtures, Dies & Mold Economics worked example

Mold Cavitation Economics at 99% molding machine uptime: a worked example

Push molding machine uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when mold cavitation economics in tooling, fixtures, dies and mold economics is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Parts per mold shot (cavity count): 4 units / cycle (unchanged)
  • Rated mold shots before service: 480 cycles (unchanged)
  • Molding machine uptime: 99 % (raised for this scenario; the documented default is 90)
  • Molded part first-pass yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross mold cavitation economics capacity = mold cavitation economics output per cycle × available mold cavitation economics cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good mold cavitation economics capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross mold cavitation economics capacity.
  • At this operating point the engine returns 19.2 units for mold cavitation economics downtime loss.
  • At this operating point the engine returns 57.02 units for mold cavitation economics yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where molding machine uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • It multiplies cavity count by rated mold shots to get gross capacity, then derates for molding machine uptime and molded-part first-pass yield to give good part capacity. 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.
