Abrasive Blasting, Shot Peening & Surface Prep calculator
Blast Cabinet Load Capacity Calculator
Small blast cabinets can become a hidden bottleneck when baskets, fixtures, and manual handling limit cycle output. This calculator converts parts per load and cycles per shift into accepted cabinet capacity after uptime and quality losses.
What this calculator does
- Estimate accepted parts per shift from cabinet load size, cycle count, uptime, and first-pass acceptance.
- a production lead needs to know how many parts a blast cabinet can finish in a shift
- Returns accepted parts available from a cabinet over the planning window.
Formula used
- Gross cabinet capacity = parts per load × cabinet loads per shift
- Accepted capacity = gross capacity × cabinet uptime × first-pass acceptance
Inputs explained
- Parts per cabinet load: undefined
- Cabinet loads per shift: undefined
- Cabinet uptime: undefined
- First-pass acceptance: undefined
How to use the result
- Use it for batch planning, staffing, and deciding whether cabinet work should move to a larger blast room or automated system.
- Part geometry, nozzle access, fixture loading, media condition, and operator fatigue can change actual capacity.
Common questions
- Should reblast parts be included in load count? Include them in loads if they consume cabinet time, but first-pass acceptance will show the loss from rejects.
- What is cabinet uptime? The percentage of shift time the cabinet is available and blasting, net of maintenance, refills, and unplanned stops.
- Can this compare fixtures? Yes. Change parts per load and loads per shift to compare basket or fixture concepts.
- Does this include masking time? No. Use the masking time calculator for prep steps before the cabinet.
