How do you calculate paint line throughput?

Divide units painted by runtime to get the raw rate, then multiply by the efficiency. Painting 96 units in 8 hours is a raw 12 units/hr; at 86% efficiency the effective throughput is 10.32 units/hr.

What's the difference between raw and effective throughput?

Raw throughput (12 units/hr here) assumes the line never stops or reworks. Effective throughput (10.32 units/hr) derates that for real losses, and it's the number you should use for scheduling and capacity planning.

What is a good paint-line efficiency for forklift manufacturing?

Well-run powder or wet lines often run 80-90% effective; below 75% usually points to excessive color changeovers, first-pass paint defects, or oven bottlenecks. The 86% in the example is solid but leaves about 1.7 units/hr on the table versus the raw rate.

Does this include rework and reflows?

Yes, if you've captured them in the efficiency figure. A reflowed truck that gets repainted consumes line time without adding net output, so it shows up as lost efficiency rather than as a completed unit.

How do I raise effective throughput?

Attack the biggest efficiency loss first, batch like colors to cut changeovers, improve first-pass yield to reduce reflows, or shorten oven dwell. Each point of efficiency gained on this line adds about 0.12 units/hr.

Should I use scheduled or actual runtime?

Use actual runtime, the hours the line was genuinely available to paint. If you use scheduled hours and then also derate for downtime in the efficiency, you'll double-count the loss.

Paint Line Throughput Calculator

Paint Line Throughput tells a forklift plant how many painted units it truly clears per hour once you account for line stoppages, rework, and reflows, not just the raw count divided by the clock. Paint is one of the most common bottlenecks in lift-truck assembly because cure ovens, color changeovers, and reject reflows all eat capacity. Production planners and paint-shop supervisors use this number to balance the paint line against weld and final-assembly takt, and to decide whether a second shift or a faster cure schedule is justified. Effective throughput is the figure you schedule against; raw throughput just tells you the ceiling.

What this calculator does

Estimate effective paint-line throughput for forklift frames, masts, counterweights, cabs, forks, or lift-equipment weldments.
Use it when a powder coat, wet paint, e-coat, masking, cure oven, or touch-up process must support truck production or service refurbishment demand.
It computes effective painted units per hour by dividing units completed by runtime and then derating that raw rate by the line's efficiency.

Formula used

Raw paint line throughput = painted parts or trucks completed ÷ paint-line runtime
Effective paint line throughput = raw throughput × paint-line efficiency

Inputs explained

Trucks or parts painted:
Paint-line runtime:
Paint-line efficiency:

How to use the result

Use it when balancing the paint line against upstream weld or downstream assembly, or when checking whether paint is the constraint in your truck build flow.
A single efficiency percentage rolls together very different losses, color changeovers, oven dwell, rework reflows, and unplanned downtime, so it tells you how much you're losing but not why.
