UV Curing calculator

UV Coating Cure Cost Calculator

UV cure cost per part is the fully-shift cost of curing a coated component under UV lamps, spread across the parts that actually pass through the line. UV finishing is fast, but the economics hinge on three things estimators often overlook: consumable lamp wear, the energy draw of high-output emitters, and the labor and overhead to keep the line staffed. Process engineers and finishing estimators use this number to compare UV against thermal cure and to know whether running a short shift is bleeding money. It matters because lamps are a metered consumable with a finite hour rating, so every part that doesn't get cured still pays its share of lamp life and standby labor.

What this calculator does

  • Combine UV cure energy, lamp wear-cost, labor, and overhead to get a true coating cure cost per part - for quoting and process improvement.
  • Use it when quoting a coating contract, building a process improvement business case, or rolling cure into per-part standard cost.
  • It sums lamp-wear, energy, and labor/overhead cost for a shift, then divides by the parts cured to give a cure cost per coated part.

Formula used

  • Lamp wear cost per shift = lamp wear per part × parts per shift
  • Total cure cost per shift = lamp wear + energy + labor / overhead
  • Cure cost per part = total cure cost per shift ÷ parts per shift

Inputs explained

  • Parts cured per shift: Good cured parts only - exclude scrap so per-part cost is honest.
  • Lamp wear cost per part: Total swap cost ÷ rated lamp life ÷ parts per hour at production speed.
  • Energy cost per shift: From UV LED Energy Cost or Mercury UV Lamp Energy Cost - the shift cost number.
  • Labor + overhead per shift: Operator labor allocated to cure station plus shop overhead share for the cure cell.

How to use the result

  • Use it to cost a UV cure step in a quote, compare UV against thermal or LED cure, or test how throughput per shift changes unit cost.
  • It treats energy and labor as fixed per shift, so very short or partial shifts will look artificially expensive per part, and it excludes the coating material itself.

Common questions

  • How do you calculate UV cure cost per part? Multiply lamp wear per part by parts cured to get lamp cost, add energy and labor/overhead for the shift, then divide the total by parts cured. With 2,400 parts, $0.04 lamp wear, $85 energy, and $320 labor, the shift totals $501 and the cost is about $0.209 per part.
  • Why does lamp wear get charged per part? UV lamps and LED arrays have a rated service life in hours, so each cured part consumes a slice of that life. At $0.04/part across 2,400 parts that's $96 of lamp consumption in a single shift — a real cost, not a sunk one.
  • What drives UV cure cost down? Throughput. Energy ($85) and labor/overhead ($320) are largely fixed per shift, so curing more parts spreads $405 of fixed cost thinner. Doubling parts cured roughly halves the fixed-cost share per part.
  • UV cure vs thermal cure — which is cheaper per part? UV usually wins on energy and floor time because there's no long oven dwell, but lamp consumables and labor can flip the math at low volume. Run both per-part numbers at your actual shift throughput before deciding.
  • What is a good cure cost per part? There's no universal benchmark — it scales with part size and line speed — but for small coated parts a figure near $0.20 like the $0.209 here is typical when the line runs near capacity. Rising costs usually mean low throughput, not expensive lamps.
