Common work metals, such as tool steels, are easy to EDM with traditional graphite electrodes. Others are not. Because of their unique characteristics, questions continue to arise about effectively EDMing materials like Beryllium Copper, Titanium and Tungsten Carbide. Even though graph-ite electrodes do an admirable job of EDMing these exotic metals, there is a more [...]
There have been many theories written on how copper graphite is created, many of which are completely untrue. […]
first-rate mold company was started in 1989 by steven “We saw an opportunity in the small dimensional tools market and relied on our reputation and broad understanding of moldmaking to move into this niche,” says steven. “Small details can severely affect the quality of a finished part in complex moldmaking,” notes steven. “By providing injection [...]
Costly machinery. Technical know-how. Time-consuming machining. With tighter deadlines being forced on moldmakers in today’s competitive market, who has the time, smarts or the inclination to make their own electrodes? What is a moldmaker to do? Outsource them to a company that makes it their business to produce quality electrodes in no time at all. [...]
Unrivaled advancements in EDM technologies have become an intrinsic means of ensuring success in today’s global competitive environment. Shops today must find a method of reducing manufacturing costs while boosting productivity and providing a quality mold, on time while meeting ever-increasing demands in customer specifications. […]
Cutting is a collection of processes wherein material is brought to a specified geometry by removing excess material using various kinds of tooling to leave a finished part that meets specifications. The net result of cutting is two products, the waste or excess material, and the finished part. If this were a discussion of woodworking, [...]
By the historical periods of the Pharaohs in Egypt, the Vedic Kings in India, the Tribes of Israel, and the Mayan Civilization in North America, among other ancient populations, precious metals began to have value attached to them. […]
Metalworking predates history. No one knows with any certainty where or when metalworking began. The earliest technologies were impermanent to say the least and were unlikely to leave any evidence for long. The advance that brought metal into focus was the connection of fire and metals. […]
Deep drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. It is thus a shape transformation process with material retention. The flange region (sheet metal in the die shoulder area) experiences a radial drawing stress and a [...]
Piercing is a shearing process where a punch and die are used to create a hole in sheet metal or a plate. The process and machinery are usually the same as that used in blanking, except that the piece being punched out is scrap in the piercing process. […]
