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 forces molten metal under high pressure into a precision steel die, producing complex, dimensionally stable components in a single shot. Huaxiao’s Sand Casting service covers aluminum, zinc and magnesium alloys for high-volume production.
Because the die defines the geometry, thin walls, internal passages and fine features are reproduced consistently part after part. We add CNC machining and surface finishing in the same flow to deliver ready-to-assemble castings.
Our Sand Casting Capabilities
Backed by 15+ years of precision manufacturing experience and a vertically integrated workshop:
How Sand Casting Works
From drawing to finished part, our Sand Casting process follows four controlled steps:

Materials We Work With
We process a broad range of metals and alloys to match your mechanical, thermal and corrosion requirements:
- Aluminum (ADC12, A380) — Lightweight, conductive; the default for most die-cast parts.
- Zinc (Zamak 3, 5) — Excellent fluidity and strength for thin, intricate sections.
- Magnesium (AZ91D) — Ultra-light for electronics and aerospace housings.
- Cast Iron — High stiffness and damping for structural components.
- Stainless & Carbon Steel — For corrosion- or strength-critical cast parts.
Industries & Applications
Sand Casting is widely used across demanding industries. Typical applications include:
