PET Machine Upgrade Yields Faster Cycles.Shorter cycles and greater molding versatility are said to result from new upgrades to a general-purpose PET injection stretch-blow machine from Aoki Laboratory America Inc., Elk Grove Village Elk Grove Village, village (1990 pop. 33,429), Cook and Du Page counties, NE Ill., a suburb of Chicago; inc. 1956. With a population of c.100 at the time of its establishment on open farmland, the village has grown dramatically and steadily, largely because of its , Ill. After first upgrading its model SB III-250LL-50S (see PT, Jan. '01, p. 17), Aoki has made similar improvements to its SB III-500LL-75 unit, which makes small bottles, wide-mouth containers, or handled bottles. The upgrade raises output by at least 30% to 2360 1.5L bottles/hr, 2700/hr for 1L, and 3360 half-liters/hr. A new servo motor drives the three-station turntable, and a new rack and pinion rack and pinion Mechanical device consisting of a bar of rectangular cross section (the rack), having teeth on one side that mesh with teeth on a small gear (the pinion). If the pinion rotates about a fixed axis, the rack will move in a straight path. opens and closes the blow mold synchronously.
