Once the mold is launched, every unclear decision becomes harder and more expensive to correct and that is why late tool changes are one of the most important risks procurement teams should look at before supplier nomination and tool kick-off.

◼️Wall thickness can be reviewed.
◼️Draft angles can be improved.
◼️Ribs, undercuts, gate position, parting line, material behavior, tolerance feasibility, and ejection strategy can still be discussed during DFM.

After the tool launch, the same change can become a much bigger problem.
It may require machining, welding, inserts, mold rework, additional trials, new measurements, updated documentation, PPAP delays, customer approvals, and revised production planning.

The technical change may look small, but the overall cost impact may be significant.

𝐅𝐨𝐫 𝐲𝐨𝐮, as procurement manager, tooling should not be seen only as a cost line, but as a risk container.

Toolings do contain assumptions about the drawing, material, tolerances, process capability, validation requirements, volumes, cycle time, quality standards, and customer expectations.

If those assumptions are weak, the tool will expose them later, and when the tool exposes them, the cost is no longer theoretical.

It affects timeline, margin, supplier performance, launch readiness, internal engineering capacity, and customer confidence.

This is why 𝐃𝐅𝐌 is not a bureaucracy.
𝐃𝐅𝐌 is cost avoidance and a way to diminish risk.

At Star Plast Engineering, we believe the best time to solve tooling risk is before tooling starts. Because once the mold is launched, every unclear assumption becomes harder and more expensive to correct.
