For the overall template processing, the overall template generally uses forgings as blanks. The processing procedures are: forging, annealing, rough machining, annealing treatment to eliminate internal stress, quenching and tempering treatment, machining, and cavity finishing. The processing flow is as follows:
1. Material preparation: Cut the round bar material on the sawing machine according to the length of the material.
2. Forgings: Forging round bars into hexahedrons.
3. Annealing: Eliminate the internal stress of the forging and improve the cutting performance of the blank.

4. Rough machining: Rough machining is performed on a milling machine or planer, and the next two planes are processed, and then four planes are processed based on these two planes, leaving a finishing allowance of about 1mm.
5. Annealing and quenching and tempering treatment: The cutting amount is large during rough machining, which may be deformed due to uneven internal stress, so annealing treatment should be carried out before finishing to eliminate the deformation caused by internal stress. Quenching and tempering generally require a hardness of 35-40HRC
6. Grinding plane: On the plane grinder, grind the upper and lower planes and the two sides that are perpendicular to each other.
7. Marking: Based on the vertical sides, draw the center position and outline of the cavity, the position of the core, etc.
8. Boring: Use a coordinate boring machine to process guide post holes, core holes or sprue sleeve mounting holes.
9. Cavity processing: If the cavity is rectangular, it needs to be processed on a vertical milling machine.
10. Polishing cavity.
