Correct injection into an intermediate<br />
gate<br />
In order to obtain defined separation,<br />
the aperture in the face surface of the<br />
intermediate gate Ød should be<br />
larger than ØD. This is particularly<br />
true for reinforced thermoplastics<br />
(engineering plastics).<br />
If possible, employ a catch pit in the<br />
intermediate gate.<br />
Gating into an angled surface<br />
Direct gating into an angled surface<br />
never results in an optimal gate point<br />
with a small vestige. We therefore<br />
recommend gating into a surface at<br />
right angle to the <strong>nozzle</strong> axis.<br />
