Valve-Gate Systems from GÜNTHER
Are your demands high in terms of appearance, reduced cycle times, minimal shear stress, wide gate diameters and high process reliability? Then no need to look any further. The answer is: Valve gate technology
The GÜNTHER valve gate portfolio includes numerous valve gate nozzles and needle actuation options. This allows the application-specific adaptation to the mould concept – both technically and economically perfect. The smallest and largest shot weights and gate cross-sections ranging from 0.8 to 5.0 mm can be achieved with valve gate technology.
The innovative design of the contouring needle guide and the optimised valve gate needle allow non-contact and wear-resistant operation. When closing, the needle is centered by means of a conical guide, until it fully and precisely enters the cylindrical guide.
The needle guide is mounted on floating bearings in the material tube. If worn out, the needle guide can be easily replaced.
Special holes in the mould clamping plate allow the position of the valve needles to be adjusted individually from the outside.
Up to 50 % GF-filled plastics can be processed, depending on the application.
