The Model #75 Mini-Jector answers a long-standing need for a precision insert molding machine that is both compact and user-friendly. A vertical, 12.5-ton hydraulic clamp with a horizontal injection unit permits the use of conventional shuttle molds with parting-line injection, as used in larger vertical machines.

MODEL #75 FEATURES:

• Uses conventional shuttle molds with parting-line injection
• Compatible with molds from other machinery:
  • 6" x 8" DME shuttle bases
  • 5" x 6"N and #5" x 8"N
  • Master Unit Dies
• Machine is designed with a "sit-down" type stand for maximum operator comfort
• Formica table-top
  • Gives machine operator space to place inserts or tools adjacent to the work area
• Can be built as a single station unit or with an in-out single station shuttle table for loading convenience

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 clamp pressure is fully adjustable
  • Hydraulic knockout supplied for on-the-fly part ejection

INJECTION UNIT

• Compact horizontal injection unit features:
  • Available in 1 ounce or 2.15 ounce models
  • Efficient direct hydraulic screw drive
  • Top-loading hopper with dump tube
  • Radiused or flat-tip nozzle with either a straight orifice or a shut-off non-drool design
  • Adjustable screw and injection speeds
  • High torque drive for molding any type of thermoplastic resin
  • Shuttle table available for mold-loading convenience
  • Selectable:
    • Screw decompression
    • Sprue break
  • Adjustable screw and injection speeds
  • Adjustable back pressure
  • High torque drive for molding any type of thermoplastic resin
  • Two-pressure injection can be either timer or position controlled
  • Shuttle table available for mold-loading convenience

HYDRAULIC UNIT

• 5 HP pump motor
• Immersed 6 GPM vane pump for reliable and quiet operation
• 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 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 96 twenty-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:
  • Automatic opening when clamp opens
  • Positive monitored mechanical safety
  • Monitored hydraulic safety
  • Dual electrical interlocks
  • Air-operated
• A selectable automatic temperature “cut-back” feature will automatically reduce temperature settings if the machine goes idle

POWER OPTIONS

• 220V, three phase
• 480V, three phase

The “C-frame” option gives the machine the ability to accommodate for parts that have attached lengths of cable or tubing in a standard style vertical clamp, horizontal injection machine.  The clamp design has an open front, which gives the operator easy access for placing and removing long parts into and out of the mold.

This machine has been designed to allow for both a “side to side” and an “in and out” shuttle.
