Lost Wax Process Pneumatic Tooling Castings Surface Roughness Ra 3.2 ~ Ra6.3

Part Name:Investment casting part for pneumatic gun body in complex shape and thin wall thickness

Process: Precision Investment Casting/Lost wax process

Material: Alloy Steel

Feather:

1) the tight tolerance only 0.05mm we need 100% check this hole

2) Perpendicularity need keep in 0.1 to avoid the noice when motor running

3): 100% position check

Here's how the lost wax process is applied to create pneumatic tooling castings:

Pattern Creation: First, a pattern of the desired pneumatic tooling component is produced. The pattern can be made from wax, plastic, or other suitable materials. It replicates the shape and features of the final casting.

Mold Assembly: Multiple patterns are attached to a central wax gating system to form a cluster or tree-like structure, known as a "sprue." The sprue allows for the flow of molten metal into the mold.

Ceramic Shell Building: The pattern assembly is dipped in a ceramic slurry and coated with a fine ceramic material called "investment." This process is repeated several times, alternating between dipping and coating, to build up a robust ceramic shell around the pattern.

Dewaxing: The ceramic shell with the embedded patterns is heated to melt and remove the wax or other pattern material, leaving behind cavities in the ceramic shell.

Preheating: The ceramic shells are preheated to remove any remaining moisture and to prepare them for the metal casting process.

Metal Casting: The preheated ceramic shells are filled with molten metal, such as aluminum, brass, or steel, typically through gravity pouring or vacuum-assisted techniques.

Cooling and Solidification: The filled ceramic shells are allowed to cool and solidify, transforming the molten metal into a solid form.

Shell Removal and Finishing: The ceramic shell is broken or removed from the metal casting, often through mechanical means like vibration or sandblasting. The casting is then subjected to finishing processes such as cutting off the gating system, grinding, machining, and surface treatments as required.

Throughout the lost wax process for pneumatic tooling castings, it is crucial to maintain dimensional accuracy, surface finish, and the integrity of intricate features. This ensures the castings meet the specifications and requirements of pneumatic tooling applications.

It is recommended to work with experienced investment casting foundries specializing in pneumatic tooling castings to ensure high-quality components that meet industry standards and performance expectations. These foundries can provide guidance on material selection, process optimization, and quality control to produce reliable pneumatic tooling castings.
