Abstract

The V-Process is an innovative foundry technique that is relatively unknown in the United States (Dreger, 1976, p. 63). The V-Process, known as vacuum sealed molding of unbonded sand, is a patented industrial foundry practice. Plastic film, unbonded sand, and vacuum are used to encapsulate the mold cavity.

Initially, the V-Process was used to produce intricate ornamental and- art castings. The V-Process has been used to produce castings of all sizes and shapes including castings having thin section curtain walls. Other castings include 2600 pound iron ore crusher mills and eight ton ship anchors. V-Process castings weigh as little as a few ounces and as much as ten tons. With the exception of magnesium, most metals including gray iron, ductile iron, malleable iron, various grades of steel, stainless steel, aluminum, bronze, and other alloys, can be cast ("Vacuum Molded Zero Draft Castings," 1978).

Basic industrial equipment for the V-Process include: 1) Vacuum Pump, 2) Plastic Film Heater, 3) Vacuum Chamber Flask, 4) Vibrator, and 5) Vacuum Hoses. Plastic film and sand are the basic supplies.
