1. Material Cutting
   Use a sawing machine to cut standard-sized steel plates into rough blanks of the required dimensions.

2. Rough Milling (Face and Side Milling)
   On a gantry milling machine, flatten the six faces of the plate (primarily the major reference surfaces) and mill the basic outer dimensions, removing the majority of machining stock.

3. Drilling Hoist Holes/Process Holes
   Drill screw holes (for hoisting rings), reference pin holes, and other positioning holes on a drilling machine to facilitate handling, transportation, and alignment in subsequent steps.

4. Rough Cavity Machining (Roughing)
   Use a rough cavity milling machine or gantry milling machine to preliminarily machine the mold cavity, guide pin/guide bush holes, return pin holes, and other structural features, leaving a uniform allowance for finish machining.

5. Heat Treatment (Quenching and Tempering)
   [Critical Step]Perform quenching and high-temperature tempering on the roughly machined plate. This eliminates internal stresses generated during rough machining, homogenizes and enhances the steel’s overall mechanical properties (strength, toughness), and provides a stable material condition for subsequent precision machining.

6. Precision Grinding of Reference Surfaces
   Heat treatment may cause slight deformation. This step involves grinding the two most critical reference surfaces (typically A and B faces) on a precision surface grinder to achieve extremely high flatness, surface finish, and precise thickness, providing the sole, accurate reference for all subsequent precision machining.

7. Precision Milling
   Using the ground reference surfaces for positioning, perform finish machining on the four sides of the mold cavity, parting surface, shut-offs, slider slots, etc., on a gantry milling machine or precision milling machine to ensure perpendicularity, parallelism, and dimensional accuracy meet drawing requirements.

8. CNC Machining
   For complex shapes that cannot be completed by precision milling (such as free-form surfaces, deep cavities, 3D runner channels, angled lifter holes, etc.), perform precision milling on a machining center (CNC) based on computer programming.

9. Drilling and Tapping
   Machine all screw holes, ejector pin holes, cooling channel holes, guide pin holes, etc., and perform tapping. This step is typically done on a high-precision radial drill or CNC drilling machine.

10. Benchwork
    Perform manual finishing, including chamfering all edges, deburring, marking part numbers in specified locations, assembling standard components like guide bushings and dowel pins, and conducting flow tests on cooling channels.

11. Final Inspection
    Use measuring tools such as coordinate measuring machines (CMM), height gauges, and calipers to fully inspect all critical dimensions, hole position accuracy, and flatness, ensuring compliance with design drawings.

12. Assembly and Packing
    Clean all components, including front and rear mold cavities, guide pins, return pins, ejector plates, etc., then assemble them. Apply anti-rust oil, secure fasteners, and pack the mold base for shipment.
