Torg, My bad.. Process mix up, Forging/casting.
Forging is the process of heating metal, Aluminum, Brass and Copper, to a moldable temperature, and then using precision machined dies to forge parts to a near net shape. This process does not change the grain structure of the metal, resulting in stronger parts. When compared to machining bar stock, forged parts are already in near net shape, which reduces the cycle time required to machine the part, and gives our clients more capacity on their machining, and reduces freight time and scrap costs, ultimately reducing their cost. When compared to mold casting, which is the melting of the metal and pouring of the liquid metal into molds, forging is superior in strength - in most cases 15% stronger, and is porosity free which is ideal for cosmetic surface requirements.
The process begins with only the finest extruded raw materials, usually round stock, however, more flexibility with our mills have allowed us to design custom shapes to be extruded, reducing the overall forging cost along with supporting more complex designs. The stock is cut to length on one of five saws based on part requirements, and then is transferred into the forge ovens, where aluminum stock is heated to between 800 to 900 degrees Fahrenheit, depending on which alloy is being processed.
We then forge the parts using precision-machined closed die forging presses resulting in a perfectly dimensioned forging. Parts move from here to various trimming, heat-treating, washing, and finishing processes, and then to shipping or to machining or polishing. The final result is stronger parts, with less waste, and lower cost.
