1：Cooling Hole Locations, Quantity and depth; bottom of hole (spherical drill point).
2：Thread Specifications & Machining Requirements (Machining after heat treatment or not).
3：Large Mold Rough Machining Requirements, significant height variations, complex arch-shaped features; implementing measures to prevent deformation and cooperate with supplier for process optimization.
4：Workpiece Documentation: Photograph and record workpieces for traceability.
Suppliers are required to provide the following documentation: Material Certificate, Metallographic Report, Delivery Note (including mold number, material type, weight, quantity, heat/batch number, etc.)
Additionally, each physical workpiece must be marked with the mold number and material type/dimensions.
Metallographic report to be provided after heat treatment (by the supplier).
