I'm looking to bulk press coasters/magnets etc and aside from a UniSub who are US based, I can't find anywhere in the UK that stock production jigs for pressing items. Having some custom made seems fairly inexpensive, but what is the best/most cost effective material to have these made from? I was thinking thin MDF? The UniSub ones I see are made using steel, which of course requires much more than a powerful laser machine to cut.
Any help would be greatly appreciated! :)
