Vacuum mold casting is an advanced fabrication process that employs negative pressure to fill molds with molten material, typically metals or alloys. Unlike conventional sand casting, vacuum mold casting offers better dimensional accuracy, smoother surface finishes, and reduces defects such as porosity and incomplete filling. The process is invaluable for producing prototypes, small-batch production runs, and even fully functional end-use components across various industries, including automotive, aerospace, medical, and consumer electronics.
- Superior accuracy and surface quality
- Minimal defects and enhanced mechanical properties
- Efficient for complex shapes and thin-walled parts
- Rapid turnaround for prototyping and custom productions
- Versatile for a range of metals, including alloys and non-ferrous materials
Vacuum mold casting significantly improves metallurgical properties by reducing impurities and internal voids. The vacuum-assisted process eliminates trapped gases that typically form during traditional casting, resulting in stronger, more reliable parts. It is particularly well-suited for applications demanding high structural integrity coupled with intricate detail.

Patterns are typically created using CNC machining or 3D printing of resin models. The mold cavity is then formed in ceramic or refractory materials, selected to withstand molten metal temperatures and to provide the required surface finish. Precision in mold fabrication is crucial to achieving dimensional accuracy.
Once the mold is assembled, it is placed inside a sealed chamber, and a vacuum system removes all air and gases. This step prevents gas entrapment, reducing porosity and ensuring that molten metal fully fills intricate cavities.
Molten metal, often aluminum, zinc, or magnesium alloys, is poured into the evacuated mold cavity. The negative pressure assists in drawing the molten metal deep into thin sections and replicating fine mold details.
Controlled cooling allows the metal to solidify with tight grain structures, promoting strength and enhancing mechanical properties. Cooling rates may be adjusted to mitigate internal stresses.
The solid cast part is carefully extracted. Subsequent finishing procedures include trimming risers and feeders, heat treatment to improve properties, machining to tight specifications, and surface treatments such as polishing or coating.
Each casting undergoes dimensional inspection with CMM (Coordinate Measuring Machines), X-ray or ultrasonic testing for internal quality, and metallographic examinations to ensure compliance with specifications.
