Drawing-Based Verification at Every Milestone
Overseas procurement requires absolute assurance that the parts delivered match your CAD coordinates and tolerance callouts. Plasticpartsmfg conducts documented inspections from raw resin receipt to final boxed dispatch.
Resin Traceability & Certification
Material certifications and batch verification for virgin polymers including PEEK, Delrin POM, polycarbonate, and flame-retardant ABS.
First Article Inspection (FAI)
Full dimensional checks against 2D drawings with balloon drawing logs, CMM coordinates, and critical fit confirmation prior to batch runs.
Export Packaging & Surface Protection
Custom blister packs, anti-static foam, and desiccants to ensure optical, polished, or threaded components arrive overseas in pristine condition.
