Die casting is the process of forcing molten metal under high pressure into mold cavities. Spara primarily competes in the casting of non-ferrous metals, such as aluminum, zinc, lead, iron, and tin-based alloys. By employing the die casting technique, manufacturers are able to produce a large quantity of small parts with fine detail, superior surface quality, and dimensional consistency. Aluminum is often used because it is lightweight with a high dimensional stability for complex shapes and thin walls. Moreover, aluminum has a high degree of corrosion resistance, high thermal and electrical conductivity and retains strength at high temperatures.
Spara provides investment casting, single source casting, and gray and ductile iron casting through their three casting brands: Tech Cast, Seville Bronze, and Fairfield Castings. Tech Cast is a producer of precision investment castings for the commercial, mining, agriculture, military, and oil and gas industries. Tech Cast capabilities include producing net and near-net shapes, ferrous and nonferrous components with assisted design, using its 3-D modeling and solicitation simulation. Tech Cast casting capabilities range from castings that weigh a few ounces, to casting that weigh in excess of 300 pounds. Seville Bronze is a single source casting, varying size ranges with 3” to 40” with 50,000 pounds a day of output capabilities. Fairfield Castings is a jobbing foundry and is one of the larger foundries in the U.S. with melt, mold, and finishing capabilities. Molding methods range from squeezers to high speed Disamatic automatic molding. Fairfield Castings produces highly cored gray and ductile iron, with weights ranging from ounces to over 100 pounds. The facility produces a full range of alloys of both types of metals. Through these three distinct casting processes, Spara is able to successfully adapt to their customers' product needs.
