1300 injection unit This Arburg electric injection unit is appropriate for applications that produce packaging from common materials, like PP.
What’s new? The injection unit. At the K Show, the company ran the injection unit on an electric Allrounder 720 A with a clamping force of about 325 tons to produce round PP cups on a four-cavity mold in a 3.95-second cycle. Each of the parts weighed 12 grams and had wall thicknesses of only 0.37mm. Along with the Allrounder 720 A, a number of other injection molding machines — the Allrounders 630 A, 820 A, 920 A and 1120 A — also can run the 1300 injection unit.
Benefits Twice the speed. New motors supplied by Arburg’s recently acquired subsidiary, AMKmotion GmbH + Co KG, Kirchheim unter Teck, Germany, plus a new planetary roller screw drive, make possible injection speeds of 400mm per second — a rate that greatly surpasses previous speeds of 200mm per second.
