Material Selection for Aluminum Injection Molds

Aluminum injection molds utilize aluminum alloys for their cavities and cores. These molds offer lightweight, high thermal conductivity, and easy machining, making them suitable for small- to medium-volume production or trial runs. However, they have certain limitations in terms of wear resistance and lifespan.

The selection of materials for aluminum injection molds requires comprehensive consideration of factors such as mold size, structural complexity, service life requirements, and cost. Common aluminum alloys include:

1. Deformed aluminum alloys: These include duralumin, superduralumin, and rust-resistant aluminum. Molds are manufactured through machining or electro-machining.

2. Cast aluminum alloys: These are directly molded through casting, resulting in a short mold-making cycle and low cost.

3. Specialized aluminum alloys: These include HOKOTOL, 7075T651, and 6061. These alloys offer high strength, high thermal conductivity, excellent machinability, and dimensional stability, making them suitable for precision mold manufacturing.
