Valve-Gate

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
from GÜNTHER.

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.

Benefits

  • Savings in time and money thanks to simplified maintenance procedures and short downtimes. No need to remove the tool to replace the needle guide and needle. No need to rework the tool inserts when the gate diameter wears.

  • Long service life of the needle guide, thus cost savings and fewer downtimes.

  • Consistent gate quality over a longer period even with filled plastics.

  • Change of material is no problem with the uncomplicated adaptation of the gate.

  • Precise opening
.
  • Sequential injection moulding and cascades possible.
