CHICAGO — Riccardo Curti used NPE 1997 as a crash course in plastics after joining Pomini SpA as its rubber and plastics division manager June 1.
Curti was vice president of engineering and contracting company Cifa Progetti of Milan, Italy, before joining Pomini in Castellanza, Italy. Although Cifa does some work for Pomini such as supplying feed hoppers, Curti had little direct involvement in plastics. He replaces Mauro Medici, who has left Pomini.
Curti was getting to know Pomini's North American employees and its global customers at NPE in Chicago. He also was getting familiar with Pomini's mixing machinery, including its LCM-AX mixer/compounder which was running twice a day at its booth.
Curti said the LCM-AX, which has a mixing section and a co-rotating twin-screw extruder, can process a wide range of materials, including highly filled plastics. At the show Pomini Inc. was compounding 40 percent glass fiber-filled polypropylene and low density polyethylene with a 70 percent loading of titanium dioxide. It was making each at the rate of about 660 pounds an hour.
Formosa Plastics Corp. is using one to make 85 percent calcium carbonate-loaded ethylene vinyl acetate for shoe soles at a plant in Asia, Curti noted in an interview at his booth.
Pomini was running a 55-millimeter LCM-AX at the show. It also offers versions with barrels up to 170mm in diameter. Curti said the LCM-AX's standard length to diameter ratios are 10:1, 25:1 and 35:1.
