Plastics News senior reporter Bill Bregar reported the following product and news announcements from Plastics Fair Cleveland, held June 23-25 in Cleveland.
Sumitomo SHC press touts better clamp
SHI Plastics Machinery Inc. of America rolled out the Sumitomo SHC series of hydromechanical machines, with an improved clamp that uses a pancake hydraulic cylinder.
SHC presses replace SHA machines in lower clamping forces of 110-385 tons. Sumitomo will continue to use the SHA model for higher clamping forces. Both the SHC and the SHA have hydromechanical clamps.
Hydromechanical machines combine the advantages of toggle and direct hydraulic clamp, by providing the separate mold height adjustment and fast operation of toggle clamps, and the precision control and low-pressure mold protection of hydraulic clamps.
The SHC's clamp feeds high-pressure oil to two auxiliary cylinders, advancing the moving platen forward. A new, two-position rotary shutter quickly turns 45 degrees to form a solid column with the guide bars and the moving platen. The machine then pumps oil to the main pancake cylinder to build tonnage quickly and lock the platens closed.
When the shutter rotates back 45 degrees to open, oil is fed to auxiliary cylinders, retracting the moving platen. An N-VII control runs the machine.
Jerry Boggs, SHI vice president, said the Norcross, Ga., firm, has lowered the SHC's price an average of 8 percent below the price of a same-size SHA machine.

AEC names managers, introduces products
Auxiliary equipment maker AEC Inc. debuted new products and announced two personnel moves.
AEC promoted George Stoddard to extrusion national sales manager. He will be responsible for equipment sales to extrusion-related processes, including Whitlock conveying and drying equipment, HydReclaim blending and reclaim machinery, Application Engineering chillers and temperature controls and Nelmor granulators. Stoddard was western regional sales manager for Sterling Inc., a sister company of AEC.
AEC of Wood Dale, Ill., also named John Braaf as extrusion technical sales manager for the central region. St. Louis-based Braaf was a sales engineer at Process Control Corp. of Atlanta. His 27 years' experience include stints with bag maker Vanguard Plastics Inc., Mobil Chemical Co. and General Motors Corp.
In product news, AEC debuted its compact True Temp TDWM temperature controller.
The company also has developed its first marketing CD-ROM, which describes AEC products. It runs on Windows 95 or NT.

Barber-Colman nets new biz for controls
Barber-Colman Co. announced it has won business at two Ohio machinery makers, PH Group Inc. of Columbus and Akron Extruders Inc. of Canal Fulton.
PH Group has standardized on Barber-Colman's Maco 4000 controller for its full line of Trueblood vertical insert molding machines.
In the past, Trueblood injection presses used controllers from both Barber-Colman and Allen-Bradley Co. Inc. In 1994, the company standardized on the Maco 4000 with the Impact option as its high-end machine controller. The development announced June 15 means Trueblood has standardized on the Maco 4000 as its low-end controller.
At Plastics Fair Cleveland, PH Group showed a 30-ton Trueblood press equipped with Barber-Colman's Foxtraker production monitoring system. The press was linked via a wireless modem to the firm's booth.
Akron Extruders, which makes single-screw extruders, has picked Barber-Colman's Maco 5000EZ for its full line of machines. The firm also is using Barber-Colman's Advantage 7EF and 7HI as its standard discrete, single-loop temperature controllers; it had been using Eurotherm single-loop controls.
Barber-Colman, based in Loves Park, Ill., also said its new Maco View software allows users on any personal computer to interface with a Maco machine controller by dialing into the machine by modem.
