Agro & Pre-treated Media For Vibratory Finishing Machines

Agro Media can be used for surface brightening or final finish refinement. The Pre-treated Media is recommended for achieving a high lustre or mirror finish on components. Agro and pre-treated media is manufactured out of corn cob or walnut shell and can be used for drying, polishing and cleaning. All of our Agro and Pre-Treated Medias are bovine free and the use of a dust extractor to collect fine dust resulting from using Maizorb in a drying process is recommended.
