When buildup is creating negative e

When buildup is creating negative effects on the parts or process it is important to verify that the mold has adequate venting and that all of the vents are open. Often times the buildup will try to escape through the vent and create a large amount of residue in the vent land, which will further restrict the mold’s ability to vent. If experiencing venting-related buildup, first verify that the vents are open. To verify that vents are open the mold surface can have tooling blue applied to the side opposite where the vents have been cut. If the vents are open at all the blue will not transfer in the relieved areas of the vent. It can also be critical to know that the vent is deep enough; the depth can be measured with a depth micrometer or by closing up on a putty and measuring the putty thickness across the vent location.
