What Is The Process Of Plastic Mold Manufacturing?

The process of plastic mold manufacturing.

 

1. Low carbon steel and low carbon alloy steel mold.

For example, the process routes of 20, 20Cr, 20CrMnTi and other steels are: blanking → forging die blank → annealing → mechanical roughing → cold extrusion forming → recrystallization annealing → mechanical finishing → carburizing → quenching, tempering → grinding and polishing → Assembly.

 

2. High alloy carburized steel mold.

For example, the process route of 12CrNi3A and 12CrNi4A steel is: blanking → forging die blank → normalizing and high temperature tempering → mechanical roughing → high temperature tempering → finishing → carburizing → quenching, tempering → grinding and polishing → assembly.

 

3. Quenched and tempered steel mold.

For example, the process route of 45, 40Cr and other steels is: blanking → forging die blank → annealing → mechanical roughing → quenching and tempering → mechanical finishing → trimming, polishing → assembly.

 

4. Carbon tool steel and alloy tool steel mold.

For example, the process routes of T7A~T10A, CrWMn, 9SiCr and other steels are: blanking → forging blanks → spheroidizing annealing → mechanical roughing → stress relief annealing → mechanical semi-finishing → mechanical finishing → quenching, tempering → grinding Polishing → assembly.

 

5. Pre-hardened steel mold.

For example, steel such as 5NiSiCa or 3Cr2Mo (P20). For the direct processing of bar stock, it has been pre-hardened due to the state of supply, and can be directly processed, polished and assembled. For the process of forging and forging into blanks, the process route is: blanking → modified forging → spheroidizing annealing → planing or milling six sides → pre-hardening treatment (34 ~ 42HRC) → mechanical roughing → stress relief annealing → Mechanical finishing → polishing → assembly.
