Lost Foam Casting All of the aluminum blocks and heads in this family of engines are produced by using the "lost foam casting" process The lost foam casting process uses a expanded polystyrene replica of the part being cast. The Lost Foam casting process can be divided into three different stages: 1. Product development and prototyping in metals and plastics. Coating of the model; 3. 5 years ago | 35 views. 8. Manufacturing of a polymer foam model; 2. Lost-foam casting is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. The sand is unbonded and a foam pattern is used to form the shape of the casting. Dry coating. The rubber mold to make all the wax molds from, is made with a thick metal plate that has a hole in the center in the shape of a soft square and 2 thin plates that serve as end caps. The process of pattern making can vary depending on the number of items that will be replicated. Because of the high temperature of the molten metal, the EPS foam evaporates, leaving the pattern in the metal. Compact cluster in flask. Stacked on a conveyor belt, the pouring cavity is between two blocks each. 3 mm). The surfaces of the EPS parts are now sprayed or painted with a hard coat, where after it is placed in a mold and feeds and risers are added. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.
