Difference between vacuum casting and pressure casting

The difference between vacuum casting and pressure casting is mainly reflected in the process principle,

application scenarios and casting characteristics:

Process principle

Vacuum casting reduces metal oxidation and gas content through vacuum environment, and uses air pressure difference to solidify the sand mold, which is suitable for complex casting production. Pressure casting uses high pressure to quickly press the molten metal into the mold cavity, and the casting solidifies under pressure.

Application scenario

Vacuum casting is often used to produce special alloys (such as titanium alloys) and high-precision castings, and has high requirements for casting materials. Vacuum die-casting technology is suitable for occasions with high requirements for casting quality, such as aerospace, medical equipment and other high-precision industrial products. Pressure casting is mainly used in mass production of common metals such as aluminum alloys, and is widely used in automobiles, electronics and other fields.

Casting characteristics

Vacuum casting castings have good density and less oxidation, but the process cost is high, and are mostly used for special needs. Pressure casting castings have high surface quality and fast production efficiency, but there may be pores or shrinkage problems.
