TECHNICAL FEATURES
Machines are robust , with 5-point toggle clamp with cast platens which assure high structural rigidity and allow for good-sized guides on the tie bars. The moving platen, supported by sliding blockes, makes it possible to use heaviest moulds, maintaining maximum parallelism and precision of movement

CLAMPING UNIT
- Five-point toggle clamp system
- Lubrication system with programmable points and safeties
- Moving platen with sliding blocks
- Mould height adjustment by means of hydraulic motor
- Independent speed profiles for mould clamping and mould opening, actuated by a proportional distributor.
- Mould-protection facility with closed-loop pressure control.
- Hydraulic plate ejector
- Speed, pressure and ejector strokes programmable on screen.
- Movable drop-out chute that can be oriented in three directions.
- Drilling templates for installation of a robot on the fixed platen

INJECTION UNIT
Both the movement of the unit and the injection phase are actuated using two hydraulic cylinders for each movement. This
assures both a perfect alignment of the injection unit with the mould, and the subsequent balanced application of injection force,
while also leaving sufficient clearance around the plasticising screw to facilitate routine and special maintenance actions.
The plasticising barrel, irrespective of the screw diameter, has a constant L/D ratio and is able to assure optimal plasticising
even using standard screws. The hopper base temperature is controlled by a closed-loop thermoregulation and displayed on the
video interface.

Rotation of the screw is actuated by a hydraulic motor, with an inverter-controlled electric motor, that is available upon request.
Both the speed and pressure of the injection phase are adjustable, by profiles as well as by individual values, and actuated
through a closed-loop servo-distribution unit.
A high-dynamic response MOOG servo-valve is also available on request. The stainless steel hopper can be easily moved along its support to facilitate emptying.

• Universal thermoplastics screw with 21 L/D ratio for all diameters
• Nitrided screw and barrel
• P.I.D. temperature control with monitoring of set-point deviations and alarms by individual zones
• Thermocouple failure safety
• Automatic adjustment and control of temperature at material inlet zone (hopper base)
• Percentage and closed-loop control of nozzle temperature
• Stainless steel hopper
• Injection control by means of proportional distributor
• Adjustment of injection speed, pressure, backpressure and hydraulic motor with profiles of up to 8 steps
• Switch-over to maintenance pressure as a function of both position and hydraulic pressure
• Decompression before and after screw rotation

All other characteristics of these machines, are the same as the Unyka series.
