Uniloy Milacron of Manchester, Mich., is touting fast mold changeovers and flexible production of a range of bottle sizes for its U750-60, a one-step stretch blow molding machine.
The machine injection molds PET preforms and blow molds the bottles.
Tooling is a major focus of the machine. Uniloy Milacron said a new design allows technicians to install molds quickly as stacked assemblies. Mold changes can take five to six hours, compared with 10-12 hours for conventional systems that require piece-by-piece installation and alignment of injection cores, neck split and injection blocks and cavities.
The machine also accepts existing preform tooling for the most widely used machines today, according to Uniloy Milacron.
Another feature, a dual shut-off design on the nozzle, eliminates drool when the mold is open.
The U750-60 can be configured for two-cavity molding of neck diameters as large as 75 millimeters, or up to 14 cavities with 28mm neck diameters. Uniloy Milacron plans to introduce a wide-mouth version, for bottles with necks up to 135mm in diameter, this year.
The blow molder has a Siemens S7-300 controller.
