On the Floor
23 presses, from 75 to 1,200 tons.
Clamping force is how hard a press holds the mold shut. Shot size is how much plastic it can inject in one cycle. The bigger the part, the more of both it needs. Our range lets us match each job to the right press.
LS Mtron, 1,200 tons: our largest press, with a 253 oz shot. LS Mtron, 310 tons: we run two of these.
