Sand Casting
Sand casting packs sand around a pattern to form a mold, suited to very large and heavy parts at low tooling cost. Huaxiao delivers sand 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 Sand Casting?
Sand Casting is a specialized capability within our Casting service. Sand casting packs sand around a pattern to form a mold, suited to very large and heavy parts at low tooling cost. 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.
