The closed die operation creates products that are rich in strength and durability, which other methods cannot provide. Closed die aluminum forging process is a major manufacturing method to create small aluminum components. It primarily involves the pressing of round, hot bars in closed dies to get near net shapes or exact net shape forgings.
Aluminum Forging Process in Details
- Before aluminum alloy is forged, round bars are used to cut blanks from. The cut bars are pre-heated between temperatures of 400 to 500 degrees, depending on the alloy being used.
- During closed die component production, the heated blank is carefully hot-worked on a press or hammer. This method keeps in mind that the level of deformation is adequate to provide sufficient breakdown of the micro-structure cast originally. The component is given a rough contour with fiber or grain flow of the substance in the direction it is stressed.
- A large quantity of aluminum requirement demands closed die forging because of the comparatively high forging die costs. As shaped dies are used to produce the forged pieces, they are susceptible to strict dimensional precision.
- Precision forging dies are used to produce closed die aluminum parts, providing the product with high dimensional stability. This, in turn, greatly reduces the amount of machining required to apply to the finished product. This kind of aluminum forgings has good structural integrity and mechanical properties.
- The closed die forging technology has grown to create accurate aluminum components with high degrees of dimensional accuracy. There is the possibility of cold forging in the treatable non-heat alloys where the level of cold working is what the mechanical properties depend on.
Closed die aluminum forging process is the perfect solution for different applications where the industry needs strength and light weight at low cost.
