Increase Line Efficiency and Safety with Roeslein’s Fully Integrated UVBCs

Roeslein eNewsletter - Vol.1, Issue 3

Ultraviolet-cured bottom coating (UVBC) is becoming increasingly popular in today’s modern D&I can manufacturing processes as its benefits for plant efficiency and productivity become more widely known.  Always motivated by innovation and improvement, Roeslein & Associates designs and manufactures a UVBC system component which provides all of these benefits in an integrated module that also improves plant safety.

UV bottom coating adds superior film protection to each can’s bottom rim surface, resulting in reduced aluminum oxidation and more efficient can transfer to conveyors, transfer plates, and machine infeeds. Roeslein began offering UVBC technology to our customers in 2001 and we are the only company to build UVBC systems as self-contained modules that can be easily integrated in new or existing can lines.  Situated before basecoating and decorating in the can production line, Roeslein’s UVBC systems are equipped with either a two-roller drip-bar applicator or a graveur. Unlike conventional thermal-cured processes, which result in a bottom film thickness of 7-9 microns with 35% solids, the UVBC process achieves 2-5 microns of dry film thickness with 100% solids. Using only solids provides uniform rim coverage, which results in up to 10-15% material savings.  It also improves adhesion, ensures greater mobility, and provides excellent corrosion resistance.

The advantages of UVBCs are most dramatically demonstrated at the decorator.   Roeslein’s UVBC systems have been shown to increase throughput up to 5% at the decorator, which can mean up to 100 more cans per minute through the line.  Our standard 36-inch wide unit processes up to 4,400 cans per minute. Increased speed and fewer jams generate a significant increase in output, adding up to dramatically improved line efficiency.

In general, UVBC systems enhance safety with zero VOCs, fewer jams, and highly reliable operation.  In particular, Roeslein’s long experience with UVBC technology means that the robust safety features and interlocks we build into our UVBC systems deliver improved fire and accident safety in controlling the intense heat and light generated by UV light chambers. Like all Roeslein modules, our UVBCs are fabricated and pre-tested at Roeslein’s manufacturing facilities prior to shipment and installation. Because our engineers and construction teams troubleshoot and integrate every unit while drawing on over a decade of experience, our customers’ facilities avoid pitfalls that can cause dangerous and costly incidents or accidents.

As we continue to value and implement innovation, Roeslein & Associates proudly serves our customers using the most modern industry improvements within our unique Modularized, Unitized, and Preassembled approach. To date, 35 of our UVBC systems have been integrated in can facilities worldwide, providing benefits in efficiency, safety, and profitability.  Contact your Roeslein representative to learn how to put our experience with this innovative technology to work in your facility.
