“We obsess about shot so you don’t have to!”



Damage to parts due to using steel media in a blasting process has always been considered as “a necessary evil.”  Or so it seems.  In one case, it’s caused by the relatively high bulk density of the steel media impacting the various parts and causing them to lose their shape (warp) and separate the upper layer of metal from the lower layer (delamination).  Steel media also does nothing to slow down the process of rusting on iron parts.

The results are substantially increased costs in the blasting process due to…

  • Rejected parts which must be reworked (or most of the time…discarded) or
  • Parts that rust so quickly following blasting that they must be re-blasted prior to painting or final finishing.

Any way one evaluates blasting process damage done by steel media…it is a serious issue to be addressed.

A small but leading-edge business in Columbus, Ohio, USA, has developed the solution to this issue.  Founded in 1970, the Transmet Corporation manufactures a Cast Zinc Blasting Shot alternative (called ZA4) that is revolutionizing the blasting industry.

When compared to steel blasting media, the substantial difference in zinc’s properties allow it to do comparable finishing of metal parts without causing any delamination or warping.  The cast zinc shot also provides a temporary rust inhibitor which prevents flash rusting for days or even weeks following the blasting of iron parts.  These properties, along with giving finished parts a consistent, bright finishwithout damaging the substrateor blasting equipment (because zinc is a softer and more ductile metal) make it a considerably more desirable alternative for doing any work on aluminum, zinc or magnesium parts.  Factor in the superior durability of the cast zinc shot allowing it to last 3-5 times as long as steel and reducing dust by up to 80%, and the choice of media becomes even more clear.
