Six Cavities Custom Injection Mold High Strength Insert Plastic

Custom Injection Mold or die are the common terms used to describe the tool used to produce plastic parts in Custom Injection Molding.

Since Custom Injection Molds have been expensive to manufacture, they were usually only used in mass production where thousands of parts were being produced. Typical Custom Injection Molds are constructed from hardened steel, pre-hardened steel, aluminium, and/or beryllium-copper alloy. The choice of material to build a Custom Injection Mold from is primarily one of economics; in general, steel Custom Injection Molds cost more to construct, but their longer lifespan offsets the higher initial cost over a higher number of parts made before wearing out. Pre-hardened steel Custom Injection Molds are less wear-resistant and are used for lower volume requirements or larger components; their typical steel hardness is 38–45 on the Rockwell-C scale. Hardened steel Custom Injection Molds are heat treated after machining; these are by far superior in terms of wear resistance and lifespan. Typical hardness ranges between 50 and 60 Rockwell-C (HRC). Aluminium Custom Injection Molds can cost substantially less, and when designed and machined with modern computerised equipment can be economical for Custom Injection Molding tens or even hundreds of thousands of parts. Beryllium copper is used in areas of the Custom Injection Mold that require fast heat removal or areas that see the most shear heat generated.[16]: 176  The Custom Injection Molds can be manufactured either by CNC machining or by using electrical discharge machining processes.
