How to Avoid Unnecessary Cost Waste in Aluminum Stamping Part Manufacturing?


Aluminum alloy stamping parts are one of the hardware stamping parts, using aluminum alloy materials. Stamping parts produced from aluminum alloy with different materials, specifications and models have different uses and performances.


Aluminum stamping parts have good plasticity. Pure aluminum is very soft and has low strength, but has good ductility and can be drawn into thin wires and rolled into foil, with good machinability. Adding a small amount of aluminum to certain metals can greatly improve their performance, such as adding a small amount of magnesium and copper to make them tougher.


Aluminum materials are soft and easily broken, and some aluminum stamping parts may be damaged, scraped or deformed during subsequent processing, which makes aluminum materials relatively expensive. So, how to avoid unnecessary cost waste in the processing of aluminum stamping parts?


In the production of aluminum stamping parts:


  • In order to better stamp aluminum alloy stamping parts and reduce defect rates, 5S must be done well, especially cleaning the mold and stamping table. The mold must be clean and tidy, and free of impurities.

  • If the product has large burrs, the mold should be sent for repair and the inspection result should be supervised in a timely manner.

  • Aluminum scraps are produced when the mold pusher is pushed flat. If these scraps are dealt with in time, the punch will wear out when punching holes. After completing the daily work of the pusher, all the aluminum scraps under the pusher should be dealt with.

  • Aluminum stamping parts are easy to stack together, heat up and harden. To cool and unblock the material during punching and blanking, some pressure oil can be applied to the material before stamping.


In terms of mold manufacturing of aluminum stamping parts:


  • The aluminum material should be wrapped in PE film to prevent aluminum scraps from being generated due to bending, causing speckling damage and indentation.

  • For products with a large number of punching holes, even if there is an additional process, they should be punched from the front.

  • In the reverse folding process, aluminum materials are particularly prone to cracking. The folding line should be widened, or even not widened.

  • Slow wire cutting of the edges of aluminum stamping parts should be used to prevent burrs and improper blanking. Aluminum stamping parts are prone to high temperatures, so the hardness of the punch should be greater than 60°. SKD11 or materials exceeding that should be used, and there should be no punch quality equivalent to D2 in the stamping production.
