Evaluation of laser produced stainless steel screens
MetadataShow full item record
In an effort to develop a more acceptable alternative to the chrome-nickel screens presently in use, BSES approached the CSIRO Division of Manufacturing Technology in Sydney towards the end of 1985 to ascertain the feasibility of manufacturing fugal screens from stainless steel by some method other than the present electrodeposition technique. The eventual outcome of these preliminary discussions was that two screens (one slotted, and the other with round holes) were produced from 300 um thick stainless steel 302 sheeting using a method involving laser technology. The specifications for these two screens, together with that for the chrome-nickel screen currently used in the industry, are given in this report.
