Hot runner technology for medical<br />
products: Precision millions of times<br />
This has the advantage that the machine is able to<br />
continue conveying even with the sprue bar moving<br />
away to eject the parting line 1.<br />
“However, at the beginning of the series production it<br />
was problematic with this configuration to evacuate the<br />
pressure quickly enough from the hot runner system,<br />
remembers Moser. In principle, due to tandem<br />
technology, the material for each injection molded part<br />
has to be injected and conveyed, and finally the pressure<br />
has to be removed again from the system in half of the<br />
cycle time. With the protective caps, the material<br />
squeezed out of the system on the injection side, and the<br />
parts initially showed extreme stringing.”<br />
The problem was basically solved with the following<br />
measures: The machine valve gate nozzle was replaced<br />
by an open nozzle, the inner cross-section of the<br />
connecting nozzle was enlarged, and the machine<br />
program was optimized. Today, the cycle time of the<br />
single part has been reduced by 10%, with two parts<br />
being produced at the same time due to tandem<br />
technology with alternating injection and cooling.<br />
To sum it up, good filling performance for all cavities, no<br />
stringing, good tear-off behavior are the parameters for<br />
which the hot runner system supplied by the<br />
Frankenberg company is substantially responsible.<br />
The company was founded 25 years ago. Today it<br />
employs about 200 people, and operates together with<br />
its partners all over the world.<br />
