Case Evidence
Insert Molded Brass Nut Correction
A brass insert moved during trial and created retention and position risk.
Buyer situation
Sample photos, insert drawings, part CAD and trial notes showing brass insert movement during molding.
Main risk
A brass insert moved during trial and created retention and position risk.
Engineering decision
Insert location, fixture support and inspection criteria were treated as the mold problem, not only an operator handling issue.
Sample gate
The next sample gate checked insert position, pull-out behavior, flash around the insert and assembly torque fit.
Evidence
Fixture and insert placement changes created a clearer T1 inspection gate.
Buyer takeaway
Insert molding quotes should define insert control and inspection before steel; otherwise the buyer only discovers retention risk at T1.
