How do you calculate cartridge yield?

Divide usable output by theoretical capacity. With 420 usable bonds from a 500-bond cartridge, yield is 84%, which is 4 points short of an 88% target.

What is a good cartridge yield for two-part adhesives?

For static-mix dual cartridges, 85-92% is realistic once you account for unavoidable mixer purge and dead volume. Single-component cartridges can exceed 95%. The 84% in the example is slightly under a sound 88% target.

Why don't I get full capacity from a cartridge?

Initial purge to establish mix ratio, static-mixer dead volume, residual film left on the piston, and the unusable slug at the cartridge end all subtract from rated capacity before any of it reaches a bond.

How do I improve cartridge yield?

Use smaller-volume static mixers, minimize purge length to the spec minimum, switch to longer cartridges to amortize fixed dead volume, and train operators to fully express the piston before discarding.

What does the yield gap tell me?

It's how far you are from target in percentage points. The 4-point gap in the example flags recoverable waste; multiply it by your cartridge spend to size the savings opportunity.

Yield vs cost per bond — how do they relate?

Lower yield directly raises cost per bond because you pay for the whole cartridge but only some becomes bonds. Improving yield from 84% to 88% cuts effective adhesive cost per bond by roughly 5%.

Cartridge Yield Calculator

Cartridge yield is the percentage of a sealant or adhesive cartridge that actually ends up in usable bonds versus what the cartridge nominally holds. Assembly and dispensing engineers track it because every cartridge loses material to dead volume in the nozzle, static-mixer purges, residual film on the piston, and end-of-cartridge dribble. A two-part epoxy cartridge that yields only 84% means one in six dollars of adhesive never reaches a joint. Tracking yield against a realistic target turns that invisible waste into a number you can attack.

What this calculator does

Calculate usable bonds or beads from a cartridge compared with theoretical cartridge capacity and target yield.
a purchasing manager needs to estimate usable output from cartridges, syringes, or sausage packs
It computes the usable yield of a cartridge as output divided by rated capacity, and the gap between that yield and your target.

Formula used

Usable cartridge yield = usable cartridge output ÷ theoretical cartridge capacity
Yield gap = target cartridge yield - usable cartridge yield

Inputs explained

Usable cartridge output:
Theoretical cartridge capacity:
Target cartridge yield:

How to use the result

Use it when evaluating cartridge or mixer changes, costing two-part adhesive per bond, or quantifying purge and residual waste on a manual or robotic dispensing cell.
It treats output and capacity as directly comparable; if output is counted in bonds and capacity is a volume, you must convert to a common basis first, and the figure says nothing about whether the dispensed mix ratio was correct.

Current U.S. benchmarks

The producer price index for industrial chemicals stands at 344.336 (BLS, May 2026), up 16.1% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 11,391 plastics and rubber products establishments employing about 815,988 workers (Census County Business Patterns, 2023).
