Forging aluminum alloys involves converting a uniform blank shape into a final product. Forging is only possible by hammering the material between shaped or flat dies.
However, other companies use closed die forging, also known as impression die forging. Closed die forging involves the dies moving towards each other. They cover the workpiece wholly or partly.
The heated raw metal, in this case, aluminum, is placed in the bottom die. The raw material is usually similar in size or close to the size of the final aluminum forging product.
Why Conduct Closed-Die Forging?
Closed-die forging is excellent because it works with the aluminum’s internal grain structure. Therefore, the result is long-lasting and stronger products.
Unlike other forging types, little to no machining is necessary for closed-die forgings. The process uses the force from a press or hammer and heat.
The aluminum metal flows and fills the shaped-die spaces, die impression, or mold. These molds convert a block of metal into aluminum forging products of your choice.
Closed-Die Forging Advantages
During forging, you can choose to use open-die forging or closed-die forging. So, here are the pros of using the latter:
• You create more precise and consistent impressions
• Closed-die forging produces better surface finish and superior properties
• There is minimal or no machining necessary
• Closed-die forging is cost-effective, especially for large production
• You can achieve measurements with tighter tolerances and different shapes
• With closed-die forging, you can reproduce any shape you wish
Closed-die forging has several advantages. Still, it is essential to check for disadvantages. The cons include:
• Less economical for small or short production runs (due to the cost of die production)
• Uses costly machines and furnaces
Products of aluminum forging are available through various companies that work with an extensive range of forged components. Ensure that all the products are inspected and assessed for quality before using them in your industry.
