PET units take aim at high-speed production. (Keeping up with Blow molding).Two new high-output integrated injection stretch-blow machines for PET--one geared for recycled material and the other an upgraded model for wide-mouth products--were introduced recently by Aoki Technical Laboratory Inc. in Japan. (U.S. office is in 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.) Aoki's new model 250LL-50S is designed to mold new PET bottles from 100% recycled bottle flake without having to repelletize the PET. The new unit operates at up to twice the production rate of the previous model 250LL-50, unveiled at the K2001 show in Germany. Features of the new machine system include a vented barrel and special screw, agitator ag·i·ta·tor n. 1. One who agitates, especially one who engages in political agitation. 2.

It can mold bottles with neck finishes from 18 to 107 mm, in 1 to 10 cavities, at rates from 120 to 5000 bottles/hr. Aoki also upgraded its SBIII-350LL-100 model with 25% greater injection pressure, 30% higher screw speed, and a larger (60-hp) hydraulic pump motor (previously 50-hp). The unit is designed mainly for PET jars of 2 to 6 liters. It can handle neck finishes of 26 to 120 mm. It can run two to 10 cavities at 350 to 6000 parts/hr. At a recent demonstration, it molded 220-cc, 13-g beverage cups in six cavities with a cycle time under 9 sec-or 2700 bottles/hr. Tel: (847) 981-6000, www.aokitech.co.jp |
