The first trial checks mold function, not parts. We verify parting line action, ejector movement, slides, lifters, and water lines. Issues caught here get fixed before any plastic runs through the tool.
The first plastic parts come off the mold. We run short fills, full shots, and packed parts to see how the tool fills, where it short shots, and where flash, sink, or warp shows up. Parts are dimensionally checked against your print.
Once T1 corrections are in, T2 runs at full process conditions for a stable batch, often 30 or more consecutive shots. This confirms the process window, cycle time, and dimensional repeatability. Capability checks are run on critical features when the program calls for it.
Each trial ends with a written report. Parts, photos, dimensions, and process settings are all documented. You see what we saw and what we changed before the next stage runs.
The mold is signed off only after it meets the criteria set at the start of the project. From there, it moves into production with a process sheet, sample parts, and a tool history file already started.
