How do you calculate kitting labor load?

Divide the number of kit line items by the lines your picker completes per hour, then multiply by one plus the setup and shortage allowance. With 180 lines at 24 lines/hr the base is 7.5 hr; a 20% allowance brings it to 9.0 hr.

What is a realistic kit lines per hour pace in a composites clean room?

It varies widely. Simple consumable and fastener pulls can exceed 40 lines/hr, while cutting and labeling individual prepreg plies with shelf-life tags often drops to 15-25 lines/hr. The 24 lines/hr default sits in a typical mixed-kit range.

Why add a setup and shortage allowance?

Because real kitting time is never just picking. The 20% allowance in the example covers freezer thaw staging, finding the next roll, resolving shortages, and re-labeling — turning 7.5 base hours into a defensible 9.0 hours.

How is this different from layup labor hours?

This number stops at the staged kit. Layup hours cover plying onto the tool and debulk. Kitting load is the upstream feeder; if it is understaffed, your layup crew burns expensive clean-room and freezer-out time waiting.

What is a good allowance percentage to use?

Stable, well-stocked kits run 10-15%; programs with frequent shortages, expired-material swaps, or new part numbers justify 25-35%. Track actual versus picked time for a month and set the allowance from your own data.

Can I use this to staff a kitting shift?

Yes. If the cell must release 180 lines and the result is 9.0 labor hours, one picker covers it in just over a shift, or two pickers finish in well under half a shift, leaving freezer-out buffer.

Composites, Fiberglass & Advanced Materials calculator

Kitting Labor Load Calculator

Kitting Labor Load tells a composites shop how many labor hours it takes to assemble a layup or bonding kit before a single ply ever reaches the tool. It is the number a production planner, material control lead, or clean-room supervisor uses to staff the kitting bench and protect cure-cell scheduling. In aerospace and wind-blade composites, kit prep — pulling prepreg rolls from the freezer, cutting plies, counting core, and staging consumables — is a hidden bottleneck that quietly delays the autoclave. Sizing it correctly keeps the layup crew from waiting on the kit cart.

What this calculator does

Estimate labor hours to kit fabric, prepreg plies, core, inserts, bagging consumables, and resin materials.
planning composite material kitting labor
It computes the total labor hours to pick and stage a composite kit by dividing kit line items by hourly picking pace, then adding a percentage for setup and shortage handling.

Formula used

Base kitting labor load = composite kit line items ÷ kitting completion pace
Estimated kitting labor load = base time × (1 + kitting setup and shortage allowance)

Inputs explained

Composite kit line items to pull:
Kit lines completed per hour:
Setup and shortage allowance:

How to use the result

Use it when planning shift staffing for a kitting cell, quoting a new layup program, or diagnosing why finished kits are not arriving at the layup table on schedule.
It assumes a steady picking pace across all line items; freezer-out-time limits on prepreg, expired shelf-life pulls, or a heavy mix of large core panels versus small fasteners can make a single average pace misleading.

Current U.S. benchmarks

The producer price index for plastic resins and materials stands at 319.371 (BLS, May 2026), up 19.5% from a year earlier. Quotes priced off last quarter's material cost miss this move.
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
