| description | Methods of improving a surface finish of a casting pattern for an investment casting process, methods of forming an investment casting, and smoothed casting patterns. The methods for forming the casting patterns having an improved surface finish include sealing the casting pattern with a first coating material to form a sealed casting pattern and smoothing the sealed casting pattern with a second coating material to form a smoothed casting pattern. The methods for forming the investment casting include covering a smoothed casting pattern with a mold material to define an enclosed mold volume, curing the mold material to form a cured mold material, flowing the smoothed casting pattern from the enclosed mold volume to define a void space, filling the void space with a liquid investment casting material, and solidifying the liquid casting material to define an investment casting. |
