.~ Shaping a forming surface (e.g., mold making, etc.) {8}
14
.~.~ With subsequent coating of casting surface with cast product treating or release material
DEFINITION
Classification: 164/14
(under subclass 6) Process directed to shaping a forming surface combined with the step of coating the so formed surface with a treating material for perfecting a subsequent casting operation.
(1) Note. The primary function of the coating provided for herein is for treating the casting surface to perfect the casting operation, e.g., release agent or lubricant to allow easy withdrawal of cast product, fluxing or wetting agent. If the main purpose of the coating is to retain or shape the work during the casting operation and not merely to perfect the casting operation then the operation will be found in subclasses 23+.
