The following items were covered by Plastics News reporters Bill Bregar and Tom Ford from Plastics Fair Cleveland, held June 13-15 in Cleveland.
Krauss-Maffei Corp. announced a new, larger machine in its C-Range line, with 220 tons of clamping force.
The C-Range had been available only with 44-88 tons.
Krauss-Maffei said the main distinguishing feature is the compact design of its cantilevered clamping unit, which the company said gives the machine one of the smallest footprints in the market. Other features include lubrication-free clamping, 10 stages of injection profiles, generous platen spacing and a wear-resistant screw and barrel.
Krauss-Maffei is based in Florence, Ky.
Boy Machines Inc. introduced a new arrival in the world of small injection molding machines: The 25D and 25M have 28-ton clamping force capabilities, and are the smallest of the Exton Pa.-based company's family of injection molders.
Introduced for the first time at the show, the models offer seven shot sizes, from about one-half ounce to 2 1/5 ounces, and a four-tie-bar configuration that Boy says offers more precise management of the platen. The machines are geared for small and precision part-making and can handle liquid silicone, thermoset plastics and elastomers.
``The 25D is a digital machine, and the M is a totally closed-loop computerized system,'' said John Johnson, national sales manager. ``This enhances control.''
The self-monitoring M machine reviews functions every 10 milliseconds.
New SGM replaces Sumitomo's SG series
Sumitomo Plastics Machinery showed its new SGM series of machines, which replaces the SG series.
The SGM maintains the rigid double-toggle clamp design of the SG, but Sumitomo has improved the shot weight accuracy and repeatability. The machine also has a smaller footprint, is easier to use and is competitively priced, according to the company.
Sumitomo, based in Atlanta, will offer two types of SGM machines. For molding applications that require special process control capabilities, the SGM-S includes a full-color controller and dual servo-valve, closed-loop hydraulics. The SGM-H, with newly designed proportional valve hydraulics, offers a cost alternative for most applications, Sumitomo said.
