Bonny Doon 100 Ton Hydraulic Press Overview

In this video by Rio Grande, Phil Poirier and Brooke Barlow demonstrate how quickly and easily the 100-ton press can create a master hob by imprinting die cavities into a hard piece of steel. They also demonstrate how the same press can be used as a coining press to achieve remarkable detail.
Rio Grande stands for makers who create with their hands and their hearts and who are courageous enough to make jewelry their livelihood.

Hello, we spoke to our Jewelry Tech Team and they said unfortunately we do not have any coining on ST37 steel here at Rio Grande so we do not have good information on that. We apologize we could not offer more information, but would suggest searching google for this specific process.
