Electric Cold Runner Moves the Needle on LSR Molding
Austria’s Elmet has introduced an all-electric SMARTshot E valve-gate cold runner system with servo-driven nozzle needles. The architecture reportedly maximizes flexibility and precision when injecting two-component liquid silicone rubbers (LSRs) into multi-cavity molds. Compact, brushless DC servomotors move and position the needles of the SMARTshot E as the nozzle opens and closes. An 18.5-in. color display allows rapid and consistent needle positioning to an accuracy of 0.002 mm. Thanks to opening and closing…
