Paint and Coating Removal

Transmet’s Cast Aluminum Shot and Cast Zinc Shot blast media have found many applications in paint and coating removal. Initially, we found a strong market with automotive component re-builders who needed to remove old paint without damaging threaded holes, cast in part numbers or otherwise damaging their cores.

Our Cast Aluminum Shot and Cast Zinc Shot have proven to be cleaner and more cost-effective than other methods like chemical stripping, burn off and even abrasive blasting with other media such as zinc cut wire, plastic media, walnut shells, soda blasting, glass beads, etc.

Our unique casting process and alloy solidification with these have resulted in long lasting, low dust and cost-effective solutions for many coating removal needs.

Plus, as time went by, we started working with companies that were involved with removal of “tougher” coatings like powder coatings, e-coat, stronger liquid paint and more from rejected parts, fixtures and jigs. For these jobs, our Stainless Steel Grit has been ideal for removing paint and coatings from metal parts and slightly profiling them to improve adhesion when the new paint is applied.

Transmet Cast Shot blast media will last over 10,000 hits before it needs replaced.  Plastics, nut shells, soda, sodium bicarbonate, wheat starch and others will only last about 10 hits before they turn to dust.  This means you will use 1,000 times less media using Transmet’s cast shot media which will save substantially on media costs.
