Uniloy-Milacron will "two-step" into NPE 2000, as it enters the market for that type of PET blow molding machines with an all-electric model. Two-step machines (also called two-stage) blow mold PET preforms that are made on a separate injection molding machine.
In Chicago, Uniloy-Milacron plans to mold PET milk bottles in two sizes — half-gallon bottles running about 4,000 an hour and single-serve, 16-ounce bottles at 7,800 an hour.
The company is billing the package as a "retro" bottle because, unlike standard bottles from high density polyethylene, PET has the clarity of glass.
Milacron Inc. bought the Uniloy blow molding machinery business in 1998 from Johnson Controls Inc. Uniloy played a key role in developing the original HDPE milk jugs with a handle, which replaced glass bottles.
The new PET bottles, in half-gallon and 16-ounce sizes, have neck finishes that match those from standard HDPE bottles, making them compatible with existing filling lines at dairies.
Milacron's Plastics Technologies Group, based in Batavia, Ohio, will market the PET blow molder as a system, which includes an all-electric injection press from Ferromatik-Milacron.
Uniloy-Milacron, based in Manchester, Mich., plans to release more technical details about the two-stage machine at NPE, when patent work will be completed. Uniloy-Milacron also will show a single-step PET blow molder at NPE.
Milacron will show a total of 37 primary processing machines at NPE, at several different exhibits in the McCormick South building.
