Mini-Jector
Model 60

The compact design (11 square feet of floor space required) allows the placement of the machine near assembly areas to avoid having to "batch mold" the parts. The machine can be integrated into a product assembly line.

The machine is offered in two injection capacities. The option of either a one or two ounce capacity injection unit permits molding either small delicate parts or fairly large parts.

CLAMPING UNIT

The Mini-Jector has a direct hydraulic clamp that is locked when closed through a system of check valves. The machine has a clamp axis potentiometer and a settable mold protect pressure to insure that the machine will not cycle with any obstruction in the mold. The final clamping pressure is adjustable to permit the use of small delicate molds at lower tonnages. A multi-stroke hydraulic knockout is supplied which may be stared during clamp open stroke to eject on "the fly". An optional stationary side ejector is available that can be used to independently eject runners. An air blast system is also available to insure automation.

INJECTION UNIT

The compact injection units feature an efficient direct hydraulic screw drive. The flat-tip nozzle can be supplied with either a straight orifice or a shut-off non-drool design. Selectable screw de-compression, sprue break, plus adjustable screw and injection speeds offer maximum versatility. The high torque drive permits molding any type of thermoplastic resin.

HYDRAULIC UNIT

The 5 HP motor drives an immersed 5 GPM gear pump for reliable quiet operation. A heat exchanger is provided in the 12 gallon reservoir, as is a return line filter with a monitor connected to the machine alarms. All components are accessible for ease of maintenance. All pressures are controlled with an electronic proportional pressure valve.

CONTROL UNIT

The machine's sequences and parameters are controlled by an extremely quick Mitsubishi PLC and LCD "touch screen" operator interface. All positions, temperatures, hydraulic pressures, and times are set in the screen. The control's settings can be stored in the machine's memory for future selection. Up to 36 eight alpha numeric set-up "recipes" can be stored. A variety of alarms and safety interlocks are part of the machine software package, and were designed with input form customers. The safety gate has a positive monitored mechanical safety, a monitored hydraulic safety plus dual electrical interlocks. A selectable automatic temperature cut-back will reduce heats if the machine is idle.
