BACK

The model #60 Mini-Jector answers a long-standing need for a precision automatic molding machine that is both compact and user-friendly. A horizontal, twin-cylinder, ten-ton hydraulic clamp with a vertical injection unit permits the use of molds with parting-line injection.

MODEL #60 FEATURES

  • Incorporates a twin cylinder design
  • Uses parting line injection-type molds
  • Compatible with molds from other machinery:
    • NEWBURY 12, 18 and 25 ton "Hornet" Machines
    • ARBURG model 150
    • ARBURG model C4B (with optional adapter)
    • Various BOY model 15 machines

COMPACT DESIGN

  • Allows placement near assembly areas to avoid having to "batch mold"
  • Can be easily integrated into a product assembly line

CLAMPING UNIT

  • Direct hydraulic clamp features:
    • Clamp axis potentiometer and a settable mold-protect pressure
      • Insures machine will not cycle with obstructions in the mold
    • System of check valves lock clamp when it is closed
    • Final clamping pressure is fully adjustable
    • Hydraulic knockout supplied for on-the-fly part ejection
  • Stationary-side ejector system is available for independent ejection of runners
  • Air blast system is available to insure part has been removed from mold

INJECTION UNIT

  • Compact vertical injection unit features:
    • Available in 1 ounce or 2.15 ounce models
    • Efficient direct hydraulic screw drive
    • Flat-tip nozzle with either a straight orifice or a shut-off non-drool design
    • Selectable:
      • Screw de-compression
      • Sprue break
    • Adjustable screw and injection speeds
    • High torque drive for molding any type of thermoplastic resin

HYDRAULIC UNIT

  • 12 gallon reservoir features:
    • Heat exchanger
    • Return line filter with monitor connected to machine alarms
    • All pressures controlled with an electronic proportional pressure valve
    • All components accessible for ease of maintenance

CONTROL UNIT

  • All sequences and parameters are controlled by an extremely quick Mitsubishi PLC
  • LCD "touch screen" used for operator interface
    • All positions, temperatures, hydraulic pressures, and times are set on this screen
  • Up to 36 eight-character alpha-numeric set-up "recipes" can be stored
  • A variety of alarms and safety interlocks are part of the machine software package
    • Designed with input from customers
  • Safety-gate features:
    • Positive monitored mechanical safety
    • Monitored hydraulic safety
    • Dual electrical interlocks
  • A selectable automatic temperature “cut-back” feature will automatically reduce temperature settings if the machine goes idle
