Examples of the growing trend toward all-electric blow molding machines for packaging will either be physically present or shown in videos and brochures at NPE. Superior accuracy, repeatability, speed, quietness, cleanliness, and energy efficiency are all claimed for the five new all-electric models being presented by four firms at the show.
Another trend on view in Chicago is the huge proliferation of PET stretch-blow machines and vendors. The newest reheat models promise wider wide-mouth capability, faster production rates, and/or shorter changeover times. Some boast new features such as preferential heating or heat-setting capability. Also look for new integrated or single-stage PET machines that can make bottles from 100% regrind or can make quick changes from round to flat bottle styles.
In extrusion blow molding, expect to see two entries in rotary continuous machinery, including the first such unit from a manufacturer of PET machines. Two brand-new dual-station machines and another with updated features are being unveiled.
Other introductions include two new 3D blow molding technologies, a new PET barrier coating technology, three new developments in PET preform tooling, a new self-teaching leak tester, new bottle profile gauge, and new bottle packaging systems.
The Fischer-W. Muller div. of Krupp Plastics & Rubber Machinery (USA) Inc., North Branch, N.J., has extended its all-electric offerings beyond the FMB1-D double-station shuttle machine to its long-stroke FMB line. The new all-electric FMB4-100 model features a four-parison extrusion head with a 100-mm center distance. An electric servomotor and ball screw for each platen govern mold movements, while a separate pair of servomotors accomplishes clamping. Another servomotor and newly developed “clamping-knuckle” device (akin to a toggle) is used to build 18.5 tons of clamp force. The FMB 6-, 8-, and 12-parison, long-stroke models (22, 33, and 44 tons, respectively) will also go all-electric, says Jack McGarry, national sales manager. A new controller for the new machines features neck-calibration and blow-pin technology developed by Tahara Machinery Ltd. in Japan.
Other firms providing literature and videos on all-electric extrusion blow machines include JSW Plastics Machinery, Elk Grove Village, Ill., and Magic North America, Markham, Ont. On the PET stretch-blow side, Uniloy Milacron and American Plastics Technologies plan to show new all-electric models (see below).
Roll-out the reheat units
Uniloy Milacron, Manchester, Mich., will unveil its first entry in two-stage PET machines, a new all-electric unit named VersaPet. The reheat machine has a 75-ton clamp, single-lane preform heating, and separate servomotor drives for the stretch-blow pin and the clamp. A four-cavity unit will produce half-gallon bottles at the show at 4000 bottles/hr, while a six-cavity version will make 16-oz bottles at 7800/hr.
As reported last month (p. 41), another new name in PET reheat machines is Tetra Pak PET Packaging Systems North America, Schaumburg, Ill. This arm of a Swedish packaging company is introducing its LX-series linear reheat machines, which are said to provide 20% higher output per cavity and tooling changeovers at least twice as fast as competing models. They are offered with one, two, and six cavities.

Industrial units debut
Two firms will show their latest in “3D” blow molding technology. Meico S.r.L. of Italy (represented by Liebco in Cleveland) will introduce to the U.S. its flashless 3D molding and sequential coextrusion system for filler-pipe and air-duct production.
NPE will also be the first North American demonstration of the “Flat Desk” segmented-mold system from Krupp Fischer-W. Muller. This “clampless” 3D parison-manipulation machine can produce multi-layer or sequentially coextruded parts.
Although the machine is too big to bring to the show, JSW Plastics Machinery will present information on a new system for producing six-layer fuel tanks by moving the molds rather than the die head (see PT, Jan. 2000, p. 19). The new PFT (Plastic Fuel Tank) Model NB 150-2CCE-MLG uses two separate mold carriages so that one is receiving a parison while the other is cooling and demolding a finished part. This system is said to more than double the output rate of auto gas tanks.
Davis-Standard Blow Molding Systems, Edison, N.J., is introducing the D-S Series accumulator-head design and digital, closed-loop shoot-and-fill control (DLC) system. The new head reportedly cuts color-change times and eliminates weld lines. DLC works with a Barber-Colman MACO 6500 controller to control fill rate and push-out speed. It will be demonstrated on a SED420D machine with twin 20-lb heads.
Krupp Kautex, will roll out its U.S.-built, 20-liter CP120S accumulator-head machine for drums. And Wilmington Machinery Inc., Wilmington, N.C., is introducing a high-volume reciprocating-screw machine for multi-layer industrial parts.
