One-Stage PET Machine Gets a Boost in Speed.Several speed-enhancing modifications have been made to the one-stage injection stretch-blow machine of 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. Its new SB III-350LL-40 is specialized for high-speed production of narrow-neck PET bottles. This upgraded model reportedly can put out 2360 1.5L bottles, 2700 1L bottles, or 3360 0.5L bottles in an hour. Speed is increased in part by use of an electric servo An electromechanical device that uses feedback to provide precise starts and stops for such functions as the motors on a tape drive or the moving of an access arm on a disk. motor to power the turntable--reportedly the first in the industry. Also, the former two-step movement of the upper and lower mold halves has been replaced with simultaneous operation Noun 1. simultaneous operation - the simultaneous execution of two or more operations parallel operation operation - (computer science) data processing in which the result is completely specified by a rule (especially the processing that results from a . Likewise, a 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. now provide synchronous opening and closing of the blow mold. In addition, screw speed has been increased, and injection pressure is 25% higher. What's more, Aoki speeds mold changes by adding an hydraulic cylinder Hydraulic cylinders (also called linear hydraulic motors) are mechanical actuators that are used to give a linear force through a linear stroke. Operation Hydraulic cylinders get their power from pressurized hydraulic fluid, which is typically oil. to slide the blowing unit out of the machine. And for improved versatility, the blowing clamp now has adjustable height. |
