Deburring and Deflashing
Taking the burr and the flash off die castings without wearing the casting surface.
Working Through The Choice
- Choose media softer than the part is sensitive to. Zinc is softer than steel and denser than aluminium, which is why it deburrs without wearing the surface.
- Size to the flash line. Grain has to be small enough to reach the flash but heavy enough to break it.
- Watch the flash point. Zinc powder has a low flash point, which Sukie states gives higher security than alumina shot.
- Confirm the finish. Zinc gives an obvious whitening effect, cast stainless makes the casting shiny and highlights the metal colour.
Frequently Asked Questions
How do I pick the grain size
Smaller grains give more impacts per kilogram and a finer finish. Larger grains carry more energy per impact. The published size range for each alloy is on the product pages, and every product states that other sizes can be customized.
Which alloy is safe on my part
Non-ferrous parts need stainless, aluminium, zinc or copper media, because carbon steel media leaves iron that rusts. Steel parts can take carbon steel cut wire shot.
Can I trial before switching
Yes. Minimum order is 500 kg on most ranges and 1,000 kg on carbon steel cut wire shot, which is low enough to run the media on real parts first.
What is the lead time
3 days on most ranges and 1 to 7 days on the stainless steel shot lines, with supply ability of 500,000 kg per month.
