Cold forging in the karat gold jewelry industry has sometimes been referred to as stamping, coining and die striking. This process has been used throughout history in the making of coins and medals as well as jewelry. Cold forging basics will always be the same as they were during antiquity; however, the fine points are constantly being refined. The process is simply described as forming a finding by using extreme force to drive raw material into a shaped cavity in a steel block. While it may sound simple, there are many subtle conditions that will effect the outcome.

Hydraulic die forming is a process which hasn’t received a lot of press. Perhaps its usefulness seems limited to mass production, and it sounds as if you need to divert rivers to do it. This article is intended to clear…
In a manufacturing environment, there are numerous pitfalls and problems that will conspire to prevent successful completion of a job. Some of these problems may be complex and involve highly technical investigations, explanations and resolutions; however, many are basic, avoidable mistakes that are easily remedied.
I first saw this technique in a work-shop held at West Dean College, Cich-ester, Great Britain, presented by Louise O’Neill and Bonnie Macintosh. I was immediately filled with enthusiasm by this technology, but the high cost for the press disturbed me. I only occasionally do such work. When back at home I began to experiment with less expensive tools and came up with a ‘low cost’ press forming technique.
How do you solve the problem of producing a limited edition of hand wrought, hollow forms in a reasonable amount of time, and yet have them fit together and look fairly identical without looking machine made? Raising, chasing or masonite die-forming might be an answer, If you are fast and accurate enough at it. But even then, those methods can’t compare with the speed, ease and precision offered by the inexpensive, simple, practical forming of such pieces by use of dies and a small hydraulic press.
In the jewelry business we all get rush jobs but I think this one may just get the prize for being the most work in 48 hours anyone has ever tried to get done. This nice young executive from the Trek Bicycle Corporation called us in a panic and said we were his last hope. He needed 11 pure platinum, 21 pure gold, 36 pure silver and 101 bronze map pins plus 2 pure platinum tie tacks for presentation purposes. In all it totaled 171 finished pieces by noon on Thursday. It was noon on Tuesday before he made it to the shop so we had 48 hours to do the job. We told him it was not gonna be cheap but we would be fair. His boss, the president of Trek, had already told him that the mission was impossible. We were pretty sure we could do it IF we could get all the materials so we took on Mission Impossible! Here is how we did it.
