Every time a part with wet adhesive or coating waits for an oven, throughput drops. A UV light curing conveyor system moves parts under a fixed lamp array at a controlled belt speed, converting a batch curing step into a continuous inline process for light-curable adhesives, coatings, and inks. How a UV Curing Conveyor Works A conveyor system pairs a variable-speed belt with one or more UV lamp heads, a focusing reflector, and a shielded curing tunnel. The energy a part receives is its UV dose, measured in millijoules per square centimeter (mJ/cm²), and it equals the lamp irradiance (mW/cm²) multiplied by the exposure time in seconds. Exposure time is set by belt speed and the length of the illuminated window. A 150 mm window at 3 m/min delivers roughly 3 seconds of exposure; at 6 m/min, about 1.5 seconds. Because both variables are adjustable, an operator can dial in the exact dose an adhesive datasheet specifies, then reproduce it on every shift. Why Conveyorized Curing Raises Output Consistent dose: A calibrated belt speed removes the operator-to-operator variation that hand-held lamps introduce. Lower labor content: Parts are loaded once and travel through the cure zone without further handling. Energy efficiency: UV curing adds energy only to the coating, not to the part mass, so it avoids the long heat-up and cool-down of thermal ovens. Inline integration: A conveyor drops into an existing assembly line between dispensing and inspection stations. Matching the Conveyor to the Job Several factors drive the specification: Belt width and part clearance: The lamp-to-part gap must clear the tallest fixture while keeping irradiance within the adhesive's working range. Lamp technology: Mercury arc lamps emit a broadband spectrum from roughly 240–420 nm, cure deep sections well, and generate ozone that requires exhaust. UV LED heads emit a narrow band at 365, 385, or 405 nm, run cool, switch on instantly, and last far longer between replacements. Speed range: A drive spanning about 0.5–6 m/min covers the majority of adhesive and coating dose windows. Curing-zone length: Longer tunnels or multiple lamp heads provide the dwell time thick or pigmented chemistries need. Incure's CDM UV conveyor platform accepts both LED and arc lamp heads, so a line can be re-tuned as chemistry changes. Arc Versus LED Lamp Heads The lamp head choice shapes both the process and the running cost: Mercury arc heads cover roughly 240–420 nm. The short-wavelength content drives fast surface cure, while longer wavelengths reach into pigmented or filled resin. Arc bulbs typically last 1,000–2,000 hours, need a warm-up period, and produce ozone that requires exhaust. They remain the practical choice for deep potting on a belt and for chemistries whose photoinitiator only absorbs below 380 nm. UV LED heads emit a narrow band at 365, 385, or 405 nm, switch on and off instantly, run cool, and hold usable output well past 20,000 hours. Because the emitted energy sits at the photoinitiator peak, less is wasted as heat, which lowers energy cost per cured part over…
