Blow Molding & Hollow Plastic Products worked example
Line Output per Shift at 99% line efficiency: a worked example
This scenario runs the line output per shift calculation on the strong side: 99% line efficiency, with every other input held at its documented default. a blow molding plant needs to confirm actual shift output before committing bottle or container demand
The inputs for this scenario
- Good containers produced: 42,000 containers (unchanged)
- Producing runtime: 12 hr (unchanged)
- Line efficiency: 99 % (raised for this scenario; the documented default is 90)
Working through the calculation
- Applying the documented formula (Raw line output = good containers produced รท producing runtime) to the inputs above produces each figure below.
- At this operating point the engine returns 3,465 containers / hr for effective line output, the number this scenario is built around.
- At this operating point the engine returns 3,500 containers / hr for raw line output.
- At this operating point the engine returns 99 % for line efficiency.
- At this operating point the engine returns 12 hr for producing runtime.
How this compares with the baseline
- Against the tool's baseline example, where line efficiency sits at 90% and the headline result is 3,150 containers / hr, this scenario comes in 10% above the baseline at 3,465 containers / hr.
- Use it when setting shift targets, validating quoted lead times, or comparing a line's actual rate against its rated cavity-count capacity. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
Results at a glance
- Effective line output: 3,465 containers / hr (headline result)
- Raw line output: 3,500 containers / hr
- Line efficiency: 99 %
- Producing runtime: 12 hr
