Gravity Casting
Gravity casting pours molten metal into a reusable metal mold under gravity, balancing quality and cost for medium volumes. Huaxiao delivers gravity casting as part of our ISO 9001:2015 certified Casting capabilities — from rapid prototyping to high-volume production, with full dimensional inspection and material certification on every order.
What Is Gravity Casting?
Gravity Casting is a specialized capability within our Casting service. Gravity casting pours molten metal into a reusable metal mold under gravity, balancing quality and cost for medium volumes. It is chosen when parts demand the specific combination of geometry, tolerance, material and volume that this process delivers best. Our engineers select and fine-tune the exact parameters for your application to balance performance, lead time and cost.
