BACK
  • Bench top, hydraulically-operated injection molding machine
  • Manual or semi-automatic vertical clamping and injection
    • Uses self-clamping V-mold technology
    • Independent short-stroke hydraulic cylinder to generate clamping force
      • This permits full-clamp force independent of injection pressure
  • Reciprocating screw plasticizing injection unit
    • Adjustments are provided for:
      • Screw speed
      • Back pressure
      • Injection pressure
      • Injection speed
  • Control unit includes:
    • Solid state timers
    • Three (3) temperature controllers for front, rear, and nozzle zones
  • Power Options
    • 220V, single phase
    • 220V with center tap (house wiring)
