Die stamping process difference

This part produced by 1500ton Transfer dies with 5 operations, which is made of casting.

Casting die is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity, which is created by using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold. Most die castings are made from non-ferrous metals, like zinc, copper, aluminum, lead, pewter, and tin-based alloys.

Advantages:

-Good dimensional accuracy

-Smooth surface

-Better strength and long lift-time

-Reduction for secondary machining operations.

Steel die is a process that assembled mainly with metal components, like upper and lower pad, stripper, holder, support plate, outer pillar, guide, inserts…

Advantages:

-Design simple

-Short lead time

-Lower investment

-Standard components

-Reduction weight

Technical Summary:

This aluminum product facing distortion and twist problems due to material grade and shape, also splitting in the side areas.

The origin forming simulation showed high risk of material decreasing, even splitting, which is out of our expectation.

Compared with distortion, splitting seems much more difficult to overcome, modify the radius, change trim line, all FCR solutions have been rejected. The surround connecting match parts will interference easily with any change. Reducing material then added, adding material then cut out… stages limit due to mass production press specification. It seems hard to find best solution to improve thinning.

Finally, we collected all data, forming, drawing, flange, hole accuracy, discussion by technical team, the product finished in a good quality, also good condition in mass production.
