An Automotive high-tech tool came to AV Injection for initial tool trailing, the tool consisted of two hydraulic side actions/cores, one mechanical core, ten drops hot runner manifold, with a total tool weight of 6.3 tonnes.

On initial start up it was apparent that there was a gate in-balance, as one impression was only 80% full. AVI removed the tool and re-checked the probe heights in relation to a condition, seating, and height position. We found that on tip was 15,000th too far forward, which restricted material flow to the cavity during the injection phase, which we corrected.

The Client was on site during the trial and highlighted a slight gas / last point of fill which they wanted improving. We improved this by reducing lock, introducing injection profile, switching over to the second stage earlier. We produced 30 samples and for the Client for them to take away and test, all parts fitted correctly passing their stringent quality control, and we were delighted when we were commissioned for the full production run for the initial pilot build.
