Needle actuatorGÜNTHER needle actuators enable precise and intelligent needle control with simple installation and connection technology. Uniform opening of the individual valve gate nozzles enables a reliable injection moulding process, even with the smallest shot weights.

ANES SLIDING MECHANISM

If a large number of closely positioned nozzles are being operated, a sliding mechanism is to be provided as the drive. Design of moulds with a high number of drops with small mould dimensions. High product quality, as all cavities are filled evenly through the synchronised opening and closing of the needles. Adjust-ment of the needle position when mounted on the machine.

Possible drive types:

Electrical Hydraulic Pneumatic

1 Fast and powerful servo drive For valve gate systems, up to 24 drops per sliding mechanism. Needle adjust-ment in the µ range. Needles close in less than 0.2 s. Can be used in clean rooms.

2 Sliding components with special coating Protected against wear, can be replaced by the customer.

THE ADVANTAGES AT A GLANCE

Precise opening and closing

Reliable injection process

Individual cavities can be shut off

Optimally adjusted needle

Precise and intelligent needle control

All moving parts can be replaced by the customer

Saves time

ENV AND EEV SINGLE-NEEDLE VALVE

Single-needle actuation on single- and multi-drop nozzle systems. Cascade injection moulding through the sequential opening and closing of needles is possible. Single-needle valve is mounted with the housing in the clamping plate. ENV single-needle valve: Minimum cavity spacing with hydraulic drive: 48 mm, with pneumatic drive: 69 mm. Needle adjustment or needle replacement without removing the mould.EEV single-needle valve: Minimum cavity spacing with hydraulic drive: 40 mm, with pneumatic drive: 57 mm. Due to a fixed needle length, needle adjustment is only pos-sible with the mould disassembled.

Possible drive types: Hydraulic Pneumatic

SMA 10 STEPPER MOTOR

Electric drive for complex applications with up to four dif-ferent needle positions per cycle. Up to 16 SMA 10 stepper motors can be controlled with extreme precision using the DPE control unit. Using the DPE control unit, the position of each individual shut-off needle in the mould can be set individually. Needle adjustment in the range of 1/100 mm. Can be used in clean rooms.

Drive type: Electrical

ANEH STROKE MECHANISM

Reliable injection process, even with small shot weights thanks to uniform opening and closing of the needles. Replacement of the external cylinder without removal of the mould. Adjustment of the needle position in the assembled mould.

Possible drive types: Hydraulic Pneumatic Electrical

NEST SINGLE VALVE GATE NOZZLE

The pneumatically driven NEST valve gate nozzle offers optimum process reliability when processing high-quality, demanding materials. Melt channel diameters from 5 to 12 mm and a length of up to 250 mm enable a variety of diffe-rent injection moulded part and mould designs.

Drive type: Pneumatic
