Review a mold design through agreed drawings, risk decisions, maintenance access and validation plans—not appearance alone. Define what remains open before steel release.
Compare tooling proposals using the same production scope, accepted-part output and traceable cost assumptions. Keep unknowns visible and avoid double counting.
Porous-metal vents can help trapped-air locations, but add design, surface and maintenance questions. Use this checklist to compare them with conventional venting before committing to the mold.
A gloss difference is an observation, not a root cause. This guide helps buyers define the requirement first, then investigate mold, material and process factors without guessing a universal setting.
A dimension that is consistently off target is not the same problem as a dimension that moves from shot to shot. Classify the pattern first, then decide which evidence can justify a mold adjustment.
A crack during ejection, after assembly, and days into service can point to different failure paths. This guide helps teams preserve evidence and investigate before choosing a correction.
