UV Curing Conveyor Throughput — Parts-per-Shift Math for High-Volume Production

A UV curing conveyor's capacity is not a brochure number. It is a short calculation built from belt speed, part pitch, and the hours a line actually runs, and doing it before purchase shows whether the cure station or something else sets your output ceiling. Q: How many parts per shift can a UV curing conveyor process? A: Parts per hour equals belt speed (inches per minute) divided by part pitch (the center-to-center spacing of parts along the belt), multiplied by 60, then multiplied by the number of parts across the belt width. Multiply by productive hours per shift for the shift total. The cure dose required by the adhesive then caps how fast the belt can run. Step 1: Fix the Belt-Speed Ceiling From Dose Throughput math must start from cure, because the belt can only run as fast as the adhesive allows. On Incure's CDM™ conveyor the belt adjusts from 1.5 to 12.0 ft/min, but the usable top speed is whichever speed still delivers the required dose with the chosen lamp head. Published figures show how much this varies. At 12 ft/min the M51 focused-beam head still delivers 12,813 mJ/cm² UVA, while the single-assembly F100x2AC arc head delivers 1,050 mJ/cm² UVA at only 6 ft/min. If a process needs 2,000 mJ/cm², the M51 can run at the platform's full 12 ft/min, but the F100x2AC cannot reach that dose even at 6 ft/min. The dual-head F100x2A, at 2,100 mJ/cm² UVA at 6 ft/min, just clears it. Step 2: Convert Speed to Parts per Hour Once the speed is fixed, the conversion is mechanical. As a hypothetical, consider parts loaded on a 4-inch pitch, one part across the belt: At 6 ft/min (72 in/min): 72 ÷ 4 = 18 parts per minute, or 1,080 per hour. At 12 ft/min (144 in/min): 36 parts per minute, or 2,160 per hour. At 3 ft/min (36 in/min): 9 parts per minute, or 540 per hour. Part pitch is set by part length plus the gap your loading method needs, not by part length alone. A robot that places parts on a fixed index, or a fixture plate that holds several parts, will each give a different effective pitch. Step 3: Use the Belt Width The CDM™ uses a 9-inch belt, and each lamp head has its own maximum part width: 1 inch on the M51, 2 inches on the M62, 4 inches on the L64, 5 inches on the F400/F500 heads, and 8 inches on the L88, F100, and F200 heads. Small parts can run more than one across if every lane falls inside the head's usable width. Continuing the hypothetical: parts 1.5 inches wide on an L88 head (8-inch usable width) could run in multiple lanes across the belt. Three lanes at 4-inch pitch and 6 ft/min triples the earlier figure to 3,240 parts per hour. The same parts under an M51 cannot run side by side at all, because its cured zone is 1 inch wide. Step 4: Apply Real Shift…

High-Power UV LED Curing for Industrial Use

An industrial curing station runs thousands of cycles a day, integrates with a line controller, and cannot stop for lamp changes mid-shift. High-power UV LED curing equipment is suited to that duty because it switches instantly, holds a stable output over tens of thousands of hours, and exposes a defined field to a repeatable dose every cycle. What "Industrial Duty" Requires Continuous operation: The head must be rated for back-to-back cycles with active cooling, not intermittent bench use. Line integration: PLC or line-controller I/O lets the cure step handshake with upstream dispensing and downstream inspection. Stable, documented output: Cure becomes a process parameter that can be logged and audited, not an operator judgment. Predictable service intervals: Gradual, even output decline means lamp replacement is scheduled, not reactive. Dose Control on an Automated Line The energy a coating absorbs is its UV dose: irradiance in mW/cm² multiplied by exposure time. On an automated station the exposure time is fixed by cycle time, so the lamp must supply enough irradiance to reach the target dose within that window, with headroom for output decline over the lamp's life. Build the recipe from the material datasheet, verify it with a band-matched radiometer at the part plane, and confirm cure with hardness or pull testing. Specifying Industrial LED Curing Field size: Cover the full cured area or batch fixture in one exposure, within roughly 10–15 percent edge falloff. Wavelength: Match the photoinitiator, commonly 365, 385, or 405 nm. Irradiance headroom: Above the target dose divided by cycle-time exposure. Cooling: Rated for the station's duty cycle and ambient temperature. Control interface: Footswitch for manual cells, PLC handshake for automated lines. Integration form factor: Fixed mount over a conveyor or inside a chamber. Incure's L-Series UV LED flood lamps are built for fixed-station duty, the CDM UV conveyor carries LED heads over a moving belt, and B/C-Series cure chambers enclose the process for operator safety and dose consistency. Designing the Cure Station Into the Line A cure step that stalls the line is worse than a slow one. Size the station so its exposure time fits inside the line's takt time with margin, and give it a bypass or buffer so a lamp fault does not immediately stop upstream work. Where cycle time is tight, two lamp heads in series each delivering half the dose let the belt run twice as fast as a single head would allow. Fault Detection and Response An industrial cure station should detect and report at least three conditions: measured output below the dose threshold, over-temperature at the head, and a missing part-present signal during a commanded exposure. Tie the first to a line stop or a reject-diverter so under-cured parts never reach assembly. Log every fault with a timestamp so recurring problems, a marginal cooling fan or a lamp nearing end of life, show up as a pattern rather than a surprise. Maintenance Access Position the head so the emitting window can be wiped and the array inspected without removing guarding…

High-Power UV LED Curing Lamps for Advanced Manufacturing

Manufacturers moving away from mercury arc lamps want the same cure speed with lower running cost. High-power UV LED curing lamps answer that by delivering concentrated narrow-band output, instant switching, and a service life measured in tens of thousands of hours instead of one or two thousand. Why UV LED Output Behaves Differently An LED head emits a narrow band centered at 365, 385, or 405 nm rather than the broad 240–420 nm spectrum of an arc lamp. All of the delivered energy sits near the photoinitiator's absorption peak, so less of it is wasted as heat or unusable wavelengths. That efficiency is the main reason LED curing lowers energy cost per cured part over the life of the equipment. Advantages for a Production Line Instant on/off: No warm-up and no idling between cycles, which cuts standby energy and lamp wear. Long service life: LED arrays hold usable output for well over 20,000 hours, reducing replacement labor and scheduled downtime. Low radiant heat: Narrow-band output adds little infrared load, so thin films and heat-sensitive plastics do not distort. Stable spectrum: Output wavelength does not drift with age the way an arc lamp's does, so cure stays predictable. Matching an LED Lamp to the Job Wavelength: Select the band the adhesive or coating photoinitiator absorbs. A 405 nm chemistry will cure slowly under a 365 nm head, and the mismatch wastes energy in the reverse direction. Irradiance and field size: Higher irradiance shortens exposure time but only matters if the uniform field covers the whole cured area. Ask for the irradiance map at your working distance. Working distance: Irradiance falls steeply with distance; fix the part-to-lens gap with a jig. Integration path: A head that works standalone on a bench should also mount over a conveyor or inside a chamber as volume grows. Incure's L-Series UV LED flood lamps span small to large fields, and the CDM conveyor platform accepts LED heads for inline curing. Cost per Cured Part, Not Just Purchase Price Comparing an LED head to an arc lamp on purchase price alone misses where the money goes over the equipment's life. An arc bulb replaced every 1,000–2,000 hours carries a recurring consumable cost plus the labor and downtime of each change. Arc lamps also draw power continuously through warm-up and idle periods because they cannot be switched on demand. An LED head runs only during the exposure, holds output past 20,000 hours, and needs no bulb inventory. On a line running multiple shifts, the running-cost difference usually outweighs the higher initial price within the first two years. Getting Full Value from Instant Switching Because an LED head has no warm-up, it can be gated to the part-present signal so it emits only while a part is in position. On a station cycling every few seconds, this cuts both energy use and the cumulative exposure hours that drive output decline. It also removes the shutter mechanism that arc systems need to block light between cycles, one less wear item.…
