Rossr Posted October 11, 2014 Report Posted October 11, 2014 Hi Folks, I have been toying around with making custom stamps. I know that magnesium setups are used. But I am wondering how the polyurethane embossing plates/stamps are being made. I have considered Cnc engraving/routing machines but seems like there is a simpler way they are being made. Its way out of my department but I am curious how it is done. Ross Quote
Members Studio-N Posted October 11, 2014 Members Report Posted October 11, 2014 I have a few and I belive they are cast so you have to have at least one really good model. The resin mix is the secret and the makers of those are pretty tight lipped about it. Quote
Rossr Posted October 11, 2014 Author Report Posted October 11, 2014 Kinda what I figured. I am betting the molds are being made on cnc machines. Interesting process R Quote
Members eransh10 Posted November 3, 2014 Members Report Posted November 3, 2014 I know that some stamps are done using a photoelectric process. Quote
Northmount Posted November 3, 2014 Report Posted November 3, 2014 eransh10, that would be photo-engraving, an etching process. A resist is photographically applied to the base metal used, then acid etched to remove the background material. Makes nice clean images, but no 3D effect. Tom Quote
