Selecting Blasting Media for Etching, Cleaning, Stripping ,
It is important to know the differences in blasting media, since different abrasive blasting media are required for different applications Blasting media can be used for purposes such as cleaning, stripping, etching, strengthening and polishing In addition to the media type, grit or mesh size is another factor to consider for your application
However, secondary blasting is the most expensive type of blasting Appropriate blast design is important in order to lessen the production of over size Secondary blasting can be done by pop shooting (blockholing) and plaster shooting (mudcapping) Shaped charges are sometime used in secondary blasting, but this is much more expensive Cast .
Blasting media is used for cleaning, finishing, deburring and peening applications Round spherical particles leave a smooth finish that slightly peens the surface, ideal for work where tolerances are important Angled or harder and sharper materials clean faster by penetrating deeper
