What is Sand Casting?
Sand casting of titanium refers to the process of manufacturing titanium parts by smelting titanium and pouring it into a sand mold in a vacuum or inert gas environment, cooling and solidifying it. Since the mold material of sand casting is cheap and easy to manufacture, it can adapt to the prototype manufacturing, low-volume manufacturing and mass production of castings. It has long been one of the basic processes for casting production.

Wstitanium Sand Casting Capabilities
The most popular sand casting titanium alloy material is Ti-6A1-4V. It has good casting properties and stable organizational properties. Compared with titanium of the same composition, the strength of cast titanium alloy is basically the same. , but its plasticity and fatigue properties are reduced by about 40%-50%. Sand casting can achieve dimensional control and consistency within tolerances of ±0.030 to ±0.125” (± 0.8 to 3.2 mm). Sand castings often utilize a variety of surface treatments, including paint, powder coating, plating, shot peening, etc. Typically, the surface finish ranges from about Ra 8 to 12.5. In addition, the minimum wall thickness is 0.125”, while the ideal wall thickness is 0.250”.

| Maximum Casting Weight (kg) | 30 |
| Minimum Wall Thickness (mm) | 0.5 |
| Tolerance (mm) | 0.02 |
| Surface Finish | Ra1.6 |
| Tolerance | CT4-CT7 |
| MOQ | 500 |

Design Optimization
Wstitanium summarizes the following design considerations based on years of sand casting experience.
- To avoid shrinkage and prevent stress concentration, each intersection is rounded.
- Gating system is optimized to properly transfer molten titanium into the mold cavity.
- Gating system is optimized to properly transfer molten titanium into the mold cavity.
- Parting line should be flat and as low as possible.
- Casting allowance is usually in the range of 1.5 mm to 6 mm.
- Draft angle is usually between 3° and 5°.
- Minimum section thickness is usually 5 mm (about 0.2 inches).
Sand casting is one of the oldest metal casting processes. It is a versatile and cost-effective process that can produce parts of various sizes, shapes and complexities. Sand molds are quite cheap and highly refractory, and are even suitable for steel foundries.
