The series is equipped with NISSEI's original 2-piston clamping mechanism that permits ideal transmission of clamping force to two sides of a mold (DC120 and above). In addition to high-speed control (control cycle: 500 microsec.) and improved repeatability by the new controller "TACT," the servomotor-driven new rotating mechanism materializes high-speed, shockless mold reversing operation (reversing time: approx. 1/2 of conventional machines).
