GÜNTHER Heisskanaltechnik GmbH is a well-known name and has their own niche in the market place with ground- breaking technical innovations with the highest standards of quality & precision.
GÜNTHER is often called as “Gunther is my supplier of choice” by the customers.
Gunther GmbH is the only company who satisfies demanding customized solutions. As a specialist, Gunther holds a number of patents to meet all the requirements.
The major benefits of Gunther Hot Runner Technology are:
Standard hot runner nozzles for direct gating from 0.0189 to 5 kg per nozzle.
If required, the modular nozzle design allows quick replacement of components.
The two-stage shaft (patented) with varying design features assures outstanding insulation in the front area of the shaft and guarantees the lowest possible heat loss between hot runner nozzle and cavity.
The individual nozzles of the series SET and DET, due to their extended nozzle head with increased heating output, are also suitable for applications with thermally sensitive materials. This means problem-free processing of technical high-temperature plastics.
The modular nozzle design allows a rapid replacement of components when required. The two-component shaft (patented) with varying design features assures excellent insulation in the front area of the shaft and the least possible loss of heat between the hot runner nozzle and the cavity.
Where requirements are high in terms of appearance, reduced cycle times, minimum shear stress and large gate cross-sections, valve-gate technology provides the solution.
Replaceable Valve Pin Guides
The new innovative design of the contouring needle guide and the optimised valve-gate needle allow non-contact and low-wear gate closing. The PM needle guide made of metallurgical powder steel ensures economical and virtually wear-free operation. While closing the needle is first centered through a tapered guide until it lowers precisely into the cylindrical guide. Another advantage is the separation of needle guide and material tube, which means that any necessary change of needle guide is a simple procedure. Gate diameters of 1.0 mm to 4.0 mm are selectable.
Type LA
The needle is centred by means of a conical guide, until it fully and precisely enters the cylindrical guide (to the axis of the gate bore).
