What is Vacuum Casting: Definition, Process, and Advantages
By pulling liquified material into molds via vacuum pressure, vacuum casting delivers refined prototypes, representations, and low-volume pieces. Unlike injection molding, which positively thrusts the material, vacuum casting synergizes vacuum suction to draw feedstock deeply into every mold embrasure, helping reproduce tight specifications and blemish-free outputs absent air pockets. The process offers several advantages over other techniques. It is commonly used for applications requiring visual prototypes, market testing, concept proofs, and limited production runs.
