Requirements & DFM
Review specifications, product function, material, assembly interfaces, draft, wall thickness, parting lines, gates, ejectors, lifters, and cooling requirements.
From RFQ and DFM review through tooling, trials, dimensional validation, and production release, CHP coordinates the decisions that determine repeatability before mass production begins.
The engineering review connects product function, assembly requirements, material behavior, tooling structure, and expected production conditions. Recommendations are documented for customer review before machining proceeds.
Review specifications, product function, material, assembly interfaces, draft, wall thickness, parting lines, gates, ejectors, lifters, and cooling requirements.
Evaluate filling, packing, air traps, weld lines, cooling, shrinkage, and warpage to improve gate and cooling decisions before mold opening.
Coordinate mold design, machining schedules, progress tracking, bench work, and tool preparation through the Suzhou and Vietnam manufacturing network.
Use trial records, dimensional inspection, FAI, issue tracking, and engineering-change control to prepare the mold for stable production.
The Vietnam NPI framework follows RFQ / Quotation → DFM → EVT → DVT → PVT → Mass Production, with documented schedule control and formal engineering-change management.
