ASHWAUBENON, Wis.—Rol-Tec Inc. has invested in a second precision laser engraving machine to meet growing demand for in-the-round flexo printing sleeves and cylinders.
This second Kronos engraving system virtually will double Rol-Tec's production capacity, and adds efficiencies and new output capabilities. This allows Rol-Tec to not only remain the sole U.S. source for the complete system of mandrels, base sleeves, rubber covering and laser engraving, but to expand its impact and work capabilities to meet rising demand, according to President Matt Umentum.
Rol-Tec purchased its first laser engraving system in 2013. The new system will be built in Austria and installed at Rol-Tec's primary manufacturing facility in Green Bay. The purchase of the two machines over the last four years amount to roughly a $1.5 million investment, Umentum said.
Both Kronos systems now used by Rol-Tec can engrave cylinders up to 126 inches long and diameters from 2.7 to 15.7 inches, Umentum said. The new precision laser engraving machine has a load capacity of 2,200 pounds.
"The added weight capacity is significant for customers in the pattern engraving business, though flexographic print cylinders and sleeves don't typically weigh that much," Umentum said.
Since 1998 Rol-Tec also has produced custom rubber, silicone and cast urethane parts for a wide range of industrial customers throughout North America. Those customers often include laminators, makers of various labels, towel and tissue manufacturers, printers, and paper and plastic engravers. Large paper towel and printing companies are an area of emphasis for the Wisconsin-based company. For example, Rol-Tec's capabilities include lamination for consumer diapers.
Vertical integration of in-house precision mold design, mold production, compound compressing, machining and grinding has allowed Rol-Tec to be cost-effective on small and large volume orders. The company routinely uses specially formulated compounds to meet highly demanding applications.
"As the U.S. becomes more complicated with manufacturing processes, our growth is more directly tied to differentiating ourselves by investing in new technologies and capabilities," Umentum said.
