Core Manufacturing Strategy

YL Solution

The forming strategy controls metal flow, section uniformity and internal integrity. Heating practice, deformation sequence, forging reduction, heat treatment and machining allowance are coordinated with defined material, dimensional, NDT and property release points.

Forming capabilityOpen-die hydraulic presses and project-specific tooling

Heat treatmentPost-forging heat treatment aligned to material and property targets

MachiningHeavy turning, milling and project-specific finishing

Inspection controlChemistry, mechanical properties, NDT and dimensional inspection

04Verified delivery

Result / Verification

Delivery basis: Build-to-print after engineering review. Large diameter and long-neck variants; As-forged or machined delivery are incorporated into the project inspection plan, with final inspection records and the quality dossier supporting acceptance and release.
