To do this, simply mark the position of the resin flow front with a marker on the vacuum bag at constant time intervals.

This decrease is also accompanied by a <b>decrease in vacuum pressure<\/b> registered by the <b>gauges<\/b>. It is important to ensure that the <b>resin speed<\/b> does not drop to levels so low that the infusion time exceeds the gel time of the resin.  <\/p>\n<p>The process can be considered successfully completed when <b>the entire surface of the part<\/b> has been <b>reached by the resin<\/b>. At this point, the <b>shut-off valves<\/b> of the infusion channels can be closed, followed by the <b>vacuum pump<\/b>. Closing the shut-off valves must always precede turning off the vacuum pump to avoid excess resin being supplied to the mold due to system inertia. <\/p>\n<p>It is good practice to keep the <b>vacuum pump<\/b> running with <b>valves closed<\/b> for the time necessary to <b>complete the transition of the resin<\/b> to a <b>solid state<\/b>.
