I came into contact last year with moldmaking, as Scott Bob says it is the most difficult discipline of toolmaking. On press tools there's a margin to "default" on tolerances, but on molds you must keep in mind the shrinkage of the moulded material, the flow of the material, where to split the mould, hot & cold spots in the mold & the runners as well. Sometimes there's a need for a "hotbox" when the runners are long.....
Well i have mentioned just a few things, but all in all i find molds much more challenging than the run of the mill type press tools, the only press tool that makes my toes curl of joy is progrssive press tools, but these type of jobs does not come my way often!
