A UV spray paint line coats plastic parts and cures the film with UV light in the same pass. The Lynvex line for plastic parts runs dust removal, spraying, levelling and UV curing on one conveyor.
Plastic mouldings carry static and dust, so the line starts with ionised-air dust removal. Automatic guns apply the UV coating, a short levelling zone lets the film flow out, and the UV curing section hardens it in seconds. The line dimensions are W2200 x D1200 x H850 mm for the standard build, or configured to your parts and takt time.
| Stage | Purpose |
|---|---|
| Dust removal | Ionised air clears static-held dust |
| Spray | Automatic guns apply UV coating |
| Levelling | Film flows smooth before curing |
| UV curing | Film hardens in seconds; parts handle at once |
Part size and takt time set conveyor width and lamp section length. Your coating supplier's data sheet sets the curing dose. Send both, plus your current reject rate if finish quality is the reason for the line — the configuration will be checked against it.
This equipment is supplied with a 12-month warranty. Spare wear parts (guns, nozzles, filters, belts) are listed in the quotation so you can stock them at commissioning.
UV coating serves parts that need a hard, glossy, fast-cured finish: phone and appliance housings, cosmetic and personal-care packaging, plastic trim and similar moulded components. Because the film cures in seconds, UV lines suit high volumes and short lead times, and they remove the work-in-progress that conventional drying accumulates between spraying and packing.
The trade-off is discipline: UV coatings are a matched system of coating, lamp output and line speed. Changing coating supplier or colour can change the curing window, so the line's lamp section and speed range are specified with headroom for the coatings you name at inquiry stage.
Three points decide UV finish quality. Dust control before spraying, because a fast-cured glossy film displays every particle. Levelling time, because the film must flow before the lamps freeze it. And lamp condition, because UV output falls with lamp age long before a lamp fails — output checks belong in the maintenance routine, and spare lamps in the commissioning stock list.
Colour change is a spray-section changeover, not a curing problem. State your colour count and change frequency.
