General Features:
* Machine designed around mold and product handling equipment needs.  
Planned for high output with minimum floor space.  High, wide discharge 
chute opening for automation accessories and easy removal of large 
products.  Open base design for quick access to all maintenance points.  
Both front and rear safety gates are roller mounted for easy access to 
mold area.  Standard mold and machine water and air manifolds for simple 
installation and quick mold changes.  Timers, pushbuttons and heat controls 
are located by the stationary platen to speed set-up.  Hunkar Monopanel 
injection process control.  Texas Instruments solid state programmable 
machine sequence control.

Electrics:
* Easy-to-troubleshoot machine sequence controls.  Plug-in 110 volt AC 
relays carrying low amperage logic signals.  Commercial solid state 
relays handle heavy solenoid switching currents.  Timers and heat 
controls are solid state.  Mercury contactors provide simple and 
reliable heater band switching.  Machine wiring runs in ducts for 
neatness.  Hinged panels provide easy access if additional controls 
are needed in the field.  Power and control panels are mounted on the 
machine, simplifying installation and saving floor space.

Hydraulics:
* All hydraulic valves are manifold-mounted directly on clamp and 
injection units, greatly reducing external piping.  Hydraulic 
accumulators are standard, providing fast clamp and injection speeds 
and high power efficiency.  Cartridge type hydraulic valves combine 
high flow rate in a compact design with precision control of speed and 
pressure.  Hydraulic controls and mold cooling manifold valves are 
located on the front of the machine for operator convenience.

Safety:
* Self-adjusting mechanical drop bars are standard on both front and 
rear safety gates.  Electric and hydraulic interlocks on both safety 
gates.  Standard low oil level and high oil temperature safety switches.  
Hinged purge guards provide protection from hot plastic.  Built-in chute 
allows easy and safe removal of nozzle purgings.  Conforms to U.S. 
Industrial Safety and Electrical codes.

INJECTION UNITS
* Reciprocating screw or two-stage injection units are available on 
most machines.  20:1 L/D Xaloy-lined barrels and hand-surfaced screws 
are standard.  DC extruder drive provides excellent energy efficiency 
with variable screw speeds from 60-200RPM.  Changing pulleys can provide
alternative torque/RPM ranges for special resin applications.
