Product information The new dimension of valve gate precision EWIKON electric drive valve gate technology

EWIKON electric drive valve gate technology EWIKON valve gate systems with electric drive technology and intelligent valve pin control are an ideal solution for demanding injection moulding applications. Apart from setting and moving the valve pins with utmost precision, several valve pin positions can be approached within one moulding cycle. Furthermore, the drive concept is absolutely cleanroom compatible and therefore perfectly suitable to be used for applications in the medical industry. The drive units are available in different sizes and can be combined with nozzles with a flow channel...

Advantages • Full control of the valve pin movement • Clean drive concept, no aerosols, absolutely cleanroom compatible • Valve pin positioning with high precision, increment: 0.01 mm, individual adjustment for each valve pin. Shutdown of selected valve pins possible • Individual setting of process parameters such as valve pin stroke length, valve pin speed and opening and closing time • Complex movement profiles of the valve pin for special applications can be realised easily • High process reliability and reproducibility • Easy integration into the mould Drive unit types Linear step motor as...

Powerful valve pin actuation The closing force of the step motor drive remains constant at all times, independently from the required valve pin stroke. Under comparable conditions - the installation dimension of the drive is a good criterion in this case - it is generally higher than the force generated by electro-magnetic drives, but can be further enlarged by the possibility to vary the valve pin speed. A general advantage of step-motor technology becomes obvious here: The slower the movement the higher the force generated. So it is possible to start the valve pin closing movement with high...

Precise and comfortable control The external touch screen control unit operates up to 32 linear step motors. With the already integrated setup software EDC (E-Drive Control) the system can be operated comfortably. For synchronous plate systems with linear servomotor the SDC (Servo Drive Control) controller is available. This control unit contains a complete servo controller that is actuated via an integrated PLC. Simple adjustment to different injection moulding machine controls by digital signals. Touch screen controller for linear step motor Controller for linear servomotor • Operates up to...

Demanding applications made easy The vast options the valve pin control offers open up new approaches to injection moulding applications and contribute to the growing tendency of integrating additional functions into the mould. Several valve pin positions are approached within one moulding cycle Time-delayed opening and closing of the valve pins Tubes and inner seals of plastic fittings are twocomponent injection-moulded within one cycle. The EWIKON electric valve gate system approaches three valve pin positions in this application. The valve pin is not only used to seal the gate, but also acts...
