The following items were gathered by Plastics News senior reporter Bill Bregar from NPE 1997, held June 16-20 in Chicago.
Precooler made for cryogenic grinding
BOC Gases of Murray Hill, N.J., introduced a liquid nitrogen precooler for cryogenic grinding.
The compact precooler requires less liquid nitrogen to chill the product before grinding. The first one was installed at CTSP Inc., a toll processor in Belle Mead, N.J.
BOC Gases also announced it is offering cryogenic deflashing systems. Parts are trimmed in seconds, said Kent Kohler, principle applications engineer.
``We have been able to significantly raise process efficiencies by utilizing liquid nitrogen to instantly freeze the flash to make it brittle,'' Kohler said.

Bell-Mark introduces flexographic printer
Bell-Mark Sales Co. of Pine Brook, N.J., introduced its single-color flexographic printer.
The Series 1230/1830 is suited for plastic and paper film converters. The 4-inch-wide printer can print company logos, product descriptions, warning logos and bar codes. Features include friction drive or direct drive and a fountain to accept an ink pump.

Thermoforming ovens have pressure control
American Catalytic Technologies of Branford, Conn., introduced gas-heated thermoforming ovens featuring its Electronic Pressure Management System.
EPMS regulates gas pressure using solid-state proportional solenoid valves. Gas flow is proportional to the electrical input from computer controls. Flow can be adjusted from 9-100 percent.

Quick-clamp system offered by Enerpac
Enerpac Automation Systems of Butler, Wis., showed a manual quick-clamping system for injection molds, suited for molding presses with clamping forces to 300 tons.
A simple handle movement locks the bayonet ring adapter into the clamping plates, which are mounted on each platen. New and existing molds can be fitted with bayonet ring adaptors that fit into the plate.
Enerpac also introduced mold holding devices for mold inspection and maintenance. The units have fixed and movable platens. Five standard models are available to accommodate molds.
Hydraulic cylinders serve to separate the mold halves, or turn each half by 90 degrees.
