Gravity Casting vs. Low Pressure Casting

Selecting the right casting process depends on your product requirements.

Gravity Aluminum Casting

Gravity casting is suitable for products such as:

Hydraulic valve blocks
Pump housings
Motor housings
Industrial equipment components

Its advantages include:

Stable dimensional accuracy
Good surface finish
Cost-effective tooling
Suitable for medium-volume production

Low Pressure Aluminum Casting

Low pressure casting is widely used for:

EV motor housings
Battery trays
Automotive suspension parts
Lightweight structural components

Compared with gravity casting, it offers:

Better internal density
Lower porosity
Improved mechanical properties
Excellent airtight performance
