CHICAGO (July 28, 5:45 p.m. EDT) — Colortronic Inc. says it has a new way of mixing PVC that takes less space, improves quality and decreases health risks.
But its continuous PVC blending line is such a step away from tradition, the company has to convince customers that the long-held rules they had no longer apply, officials said.
The biggest mind change with the Novablend System is how it eliminates heating from the system, said Robert L. Edwards, Colortronic executive vice president and chief executive officer.
"This is a big paradigm shift," Edwards said in a June 21 interview. "For years, the way of making PVC used heat, so people believed they needed heat, but they don´t.
"They look at (the Novablend) and say, `Oh, well, you´ve got to heat it yet.´ They just don´t believe it."
The system was developed by Colortronic using a high-speed mixing turbine developed by Waeschle srl of Ferrara, Italy. The resulting machine is smaller — with the entire system taking about a third of the typical space — requires only 10 percent of the energy and reduces the amount of dust prevalent in conventional systems, Edwards said.
Studies in Europe already prove that a reduction in dust reduces health hazards among workers, said Martin Skrabak, general sales manager for Waeschle.
"It is different, but it has been proven that it works," Skrabak said.
Other Colortronic introductions on display at North Hall include:
* Touchpad control systems for machines designed for ease of use on the factory floor.
* The Colorblend S digital dosing machine for free-flowing additives in low-rate feeder lines.
* The "Smart Feed" hopper designed for use with gravimetric blending systems for additive feeding of ultra-high accuracy in low through-put applications such as medical tubing, wire and cable.
