Investment Castings - American Completion Tools

	Investment Castings

American Completion Tools also supplies investment (lost-wax process or precision casting) castings characterized by close tolerances, superior surface finish and excellent dimen-sional integrity. Investment casting can be made from carbon steel, alloy steel, corrosion resistant, heat resistant & high temperature steels, aluminium & copper alloys.

Advantages:
a. The process permits mass production of complex shapes that are difficult or impossible to produce by the more conventional casting process or by machining.
b. The mould materials and the techniques used permit reproduction of fine details, greater dimensional accuracy and smoother surfaces that can not be obtained by other casting processes.
c. Castings can be produced that require little or no finishing for competition.
d. The process permits close control of metallurgical properties such as grain size, grain orientation & directional solidification, which results in close control of mechanical properties.
e. The castings produced do not vary in dimensions across parting lines, as do castings made by other processes.
