The Blueprint of Mass Production: An Essay on the Injection Mold Design Guide

The location and type of gate affect part appearance, weld lines, and packing pressure.

V. Mold Material Selection

7. Design Guidelines for Cooling Systems

Common steels: P20 (pre-hardened tooling steel for prototypes/low volume), H13 (hot-work steel for high-temp, high-volume), S7, and stainless steels for corrosive environments.
Hardness and coatings: Hardened inserts for wear resistance; nitriding, PVD/CVD coatings or chrome plating for abrasion resistance and release.
Maintenance: Plan for easy access to wear areas, replaceable inserts, and vents for long-term serviceability.
