<strong>Heißkanaldüsen</strong> <strong>Typ</strong> <strong>SLT</strong>/-<strong>DLT</strong><br />
At that time GÜNTHER Heisskanaltechnik GmbH,<br />
specialized in the processing of demanding plastics, was<br />
given an order by Moeller to test an optimized hot runner<br />
system, at first for a 2K component. For the trial Moeller<br />
selected the “button insertion guide“ for holding a<br />
pushbutton (Fig. 2, 3) made of a flame-retardant PA66<br />
(with 25% glass fibers) and a TPE.<br />

The following criteria were set for selecting the hot<br />
runner system:<br />
� � �processability of a PA66 with glass fibers and<br />
flame retardant (red phosphorus / UL94-V0)<br />
�consistent temperature profile over the whole<br />
length of the nozzle<br />
�no massive temperature increase in the nozzle<br />
�low level of shear stress on the melt in the hot<br />
runner.<br />

Stable and Material Saving Processing of Flame Retardant Polyamides with<br />
GÜNTHER Hot Runner Technology<br />
The hot runner nozzle with a two-part shaft developed<br />
and patented by GÜNTHER Heisskanaltechnik GmbH<br />
(Fig. 4) has been selected.<br />

This hot runner nozzle is setting standards in precision<br />
and economic efficiency. Various design features in the<br />
two-component shaft of the hot runner nozzle ensure<br />
excellent insulation in the front area of the nozzle and<br />
keep heat losses between the hot runner nozzle and the<br />
cavity extremely low.<br />
Due to this thermal insulation between the hot runner<br />
nozzle and the mold there is no problem in processing<br />
engineering plastics and high temperature polymers.<br />
From the lowest shot weights, as of approx. 0.019 g up to<br />
shot weights of approx. 5000 g, a wide range of<br />
applications in technical and precision injection molding<br />
are covered by the GÜNTHER hot runner technology<br />
portfolio.<br />
