N.J., discussed its all-electric Plastiblow machines at NPE. Five models can mold containers from 1 to 30 liters. They are de- signed for easy and rapid maintenance, low energy consumption, and precise repeatability of clamp movements. ELECTRIC/HYDRAULIC HYBRIDS, TOO Nissei ASB Co., Atlanta (nissei-asbus.com) has been offering all-electric machines since 2006, when it introduced the ASB- 15N/10E all-in-one injection-stretch-blow machine. With an injection clamping force of 15 m.t., this machine was built primar- ily for clean-room production of small (less than 4 oz) pharmaceu- tical and healthcare packaging with a maximum of 10 cavities. At NPE, Jamie Pace, v.p./general manager, reported that Nissei has in the works a hybrid line of machines. The first model, ASB- 12M, is slated to arrive in the third quarter. It will have servo- driven hydraulic pumps and is primarily targeted for molding of wide-mouth jars with necks up to 83-mm diam. "All-electrics have a lot of servo motors, and when servos break that can create a lot of problems, especially with a semi-skilled work force," Pace says. Uniloy North America, Tecumseh, Mich. (uniloyna.com), incorporates hybrid technology on its two largest-selling ma- chine lines, reciprocating-screw extrusion units and machine and injection-blow models. Richard K. Smith, v.p. of commercial operations, says the machine builder is still exploring ways to The all-electric ASB-15N/ 10E injection stretch-blow ma- chine from Nissei ASB Co. is designed for clean-room produc- tion of small pharmaceutical and healthcare containers. develop an all-electric solution for these machine platforms. "On these machines, which have high clamp-tonnage capability, it has been problematic and unfruitful to date finding any electric system that will generate the required clamp tonnage at the cost point we need," he says. (Note: Uniloy Milacron Europe does offer all-electric injection-blow and extrusion shuttle machines.)
