Mold core-contrast between traditional process and additive manufacturing process
Traditional crafts
1. First prepare a piece of fine material steel; 2. Milling code slots, typing codes; 3. Hole processing and tapping; 4. CNC roughing; 5. Heat treatment processing; 6. Facade body and right angle; 7. CNC for medium processing and finishing Processing; 8. WEDM processing hot nozzle hole; 9. EDM clear corner and glue plane; 10. Polishing and etching
The main problem of molds made by traditional technology is that there is no way to ensure the mold temperature, especially now that most of the molds are molds with hot nozzles or hot runners, which suffer from the phenomenon that the local temperature of the mold is too high.

Additive manufacturing process
Additive manufacturing technology is a process of creating entities through layered manufacturing. From design to 3D printing technology for end products, although the final result is a rapid prototype or functional part, the manufacturing principles are the same.
1. Prepare powder raw materials;
2.3D printing;
3. Heat treatment;
4. Right-angled hexahedron;
5. CNC for mid-processing and finishing;
6. WEDM processing hot nozzle hole;
7. EDM clear angle and glue plane;
8. Polishing and etching;
The most important thing in additive manufacturing is that the internal structure can make the design more free and at the same time make the mold temperature uniform. The material is powder, which is accumulated layer by layer through laser sintering to form a mold. Because the process accuracy of additive manufacturing can only be about 0.05-0.1mm, and the mold also needs heat treatment, the process of additive manufacturing in the mold is to replace the process before heat treatment.
