Most curing lines do not run one part forever. When a single UV light curing conveyor handles several products, the time and risk sit in the changeover — and a streamlined line is one where switching products is a short, documented routine rather than a fresh setup. Q: What changes when a UV curing conveyor switches from one product to another? A: Up to four settings can change: belt speed (which sets dose), lamp height (which sets working distance), the lamp head itself if the new product needs a different width, wavelength, or spectrum, and the fixtures or belt surface the parts ride on. The fewer of those that change between products, the faster and safer the changeover. Classify Each Changeover Before It Happens Not every switch is equal. Grouping your products by what actually changes lets you plan the line around the cheap changeovers and isolate the expensive ones. Speed-only change. Same head, same height, new belt speed. On Incure's CDM™, belt speed adjusts from 1.5 to 12.0 ft/min and directly sets dose, so a product needing more cure can often run on the same head at a slower setting. This is the fastest changeover available. Height change. Taller or shorter parts need the lamp repositioned to keep the working distance the dose was qualified at. LED heads on the CDM™ adjust from 0.5 to 2.0 inches; F400/F500 arc heads adjust from 3.0 to 6.5 inches. Head swap. A part wider than the current head's usable width, or an adhesive needing a different wavelength, means changing the lamp head. The CDM™ chassis accepts LED flood, LED focused-beam, and mercury-arc heads, so this is a head change rather than a second conveyor. Belt change. A product that rules out the standard polypropylene belt needs the stainless-steel wire belt of the CDM™ Compact, which is a separate chassis. Choose a Head That Covers the Whole Product Family The cheapest changeover is the one that never needs a head swap. Before buying, list every product the line will run and check each against the candidate head's limits: Width. Maximum part width is 1 inch on the M51, 2 inches on the M62, 4 inches on the L64, 5 inches on F400/F500, and 8 inches on the L88, F100, and F200. Wavelength. LED heads are factory-configured to one wavelength (365, 385, 395, or 405 nm). Every adhesive on the line must cure at that wavelength. Spectrum. If any product's adhesive is qualified on broadband mercury-arc cure including UVC, it needs an x2AC arc head. If one head clears every product, the line only ever makes speed and height changeovers. If no single head does, group products by head and schedule them in blocks so swaps happen once per block rather than once per order. Email Us with your product list and each adhesive's requirements, and Incure can check which CDM™ head covers the most of it.
