How To Make An Aluminum Mold With A CNC Machine

Aluminum molds are used to cast metal objects. They are made from an aluminum base material, and are very durable. Aluminum molds can be made to cast almost anything. The quality of the mold is determined by a number of factors, including the type of material being cast, the size and shape of your object and how many layers you want to add in between the base and final product

There are many ways to make an aluminum mold, but let me show you how I made my own using a CNC cutting machine.

CNC Aluminum Machining

Aluminum is one of the most common metal materials to produce components for various fields, almost all fields. Also, CNC aluminum machining is a very common process for aluminum parts.

Aluminum is very easy for machining process because the material is soft and shaping keeper, it is suitable for many different production facilities, such as machining, extrusion, stamp, casting, etc.

With its good thermal conductivity and excellent shaping feature, temperature devices and electricity device and other industries are commonly using aluminum alloy. Aluminum alloy has many different materials codes to support wider demands.

Benefits of CNC Aluminum Machining

1/ Aluminum material is soft for machining, easy for CNC machining to carry out desired shapes

2/ CNC machining aluminum parts are durable for long term using, high resistance than steel series

3/ CNC machining aluminum parts are flexible to apply many kinds of surface finishing treatments

4/ CNC machining aluminum is good resistance against low temperature, which benefits for winter products

5/ Aluminum materials can be produced by many process, for example, forging, extrusion, stamp, casting, fabrication, etc.

6/ It is basically environmental material and supporting recycle collecting, material renewal benefits the burden of world
