Sole Bonding Cure Time at 23% adhesive cure and setup allowance: a worked example

What does the result look like when adhesive cure and setup allowance reaches 23%? The full calculation is worked below with real intermediate numbers. Use this when scheduling sole attachment operations, sizing press capacity, planning work-in-progress buffer space for curing racks, or estimating bottleneck time at the sole bonding station.

The inputs for this scenario

  • Pairs in the bonding batch: 500 pairs (unchanged)
  • Sole bonding line throughput: 40 pairs / hr (unchanged)
  • Adhesive cure and setup allowance: 23 % (raised for this scenario; the documented default is 20)

Working through the calculation

  • Applying the documented formula (Base bonding time = pairs in batch / bonding throughput rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 15.38 hr for required bonding and cure time, the number this scenario is built around.
  • At this operating point the engine returns 12.5 hr for base bonding time.
  • At this operating point the engine returns 23 % for curing and setup allowance applied.
  • At this operating point the engine returns 40 pieces / min for bonding throughput rate (pairs/hr).

How this compares with the baseline

  • Against the tool's baseline example, where adhesive cure and setup allowance sits at 20% and the headline result is 15 hr, this scenario comes in 2.5% above the baseline at 15.38 hr.
  • A figure at this level is achievable when adhesive cure and setup allowance is genuinely sustained, not just peaked for a shift. A percentage allowance approximates cure as proportional to volume, but adhesive cure is partly fixed dwell, so very small batches may need more allowance than the percentage implies.

Results at a glance

  • Required bonding and cure time: 15.38 hr (headline result)
  • Base bonding time: 12.5 hr
  • Curing and setup allowance applied: 23 %
  • Bonding throughput rate (pairs/hr): 40 pieces / min
