High demands on surface finish appearance, reduced cycle times, lowest possible shear stress and large gate cross-sections. The correct answer to all these demands: valve gate technology.
Individual nozzles with hydraulic actuation are approved up to 40 bar. In case of pneumatic actuation – depending on the system – pressures up to 10 bar may be required (however, at least 8 bar).
The cylinders are arranged externally. The new, innovative design of a contour-shaping guide insert and optimized needle valve permit contact-less and virtually wear-free sealing of the gate. The new GÜNTHER PM needle guide made from powder-metallurgical steel guarantees economical and virtually wear-free operation. During the closing motion of the needle, it is first centred by means of a conical guide, until the needle fully and precisely enters the cylindrical guide. Another advantage is the division of needle guide and nozzle tube – if required, the needle guide can be replaced without effort. Gate diameters from 0.8 mm to 5.0 mm can be selected. Standardized components result in length dimensions from 30 mm to 350 mm at material tube diameters from 3 mm to 16 mm. Up to 30% glass-filled plastics can be processed.
