Mold Qualification Process The Preproduction Plastics mold qualification process consists of four steps. These steps are called Test-1 (T-1 for short), T-2, T-3 and Critical Dimension Inspection. They all have different purposes, with the final goal being to achieve a highly consistent and repeatable production part. Each phase of testing requires participation from our customer, where there may be a need for specifying such things as critical dimensions, creating tolerances that are repeatable, reviewing paint and secondary operations, verifying process control, and setting priorities.
