Sand Casting for Industrial Applications: Benefits, Process & Materials
Sand casting remains one of the most versatile and cost-effective metal casting methods in industrial manufacturing. From valve bodies to pump housings, sand casting is widely used to produce durable and complex parts across multiple sectors.
At EATHU, we specialize in OEM sand casting solutions for clients in Europe and the Middle East. Our production capabilities and strict quality control systems enable us to deliver high-performance iron and steel castings that meet the most demanding industrial standards.
What Is Sand Casting?
Sand casting is a metal casting process where molten metal is poured into a sand mold that forms the shape of the desired part. Once cooled, the sand mold is broken away to reveal the final casting. The process supports a wide range of metals, including cast iron, ductile iron, carbon steel, and stainless steel.
Thanks to its adaptability and scalability, sand casting is ideal for low to medium volume production and large, heavy components.
Industrial Applications of Sand Casting
Sand casting is extensively used in heavy industry due to its ability to handle large, complex geometries with excellent mechanical properties. Typical applications include:
Valve Bodies – industrial, water, and oil & gas sectors
Pump Housings – centrifugal, gear, and submersible pumps
Machine Bases & Brackets – for CNC machinery and equipment
Pipe Fittings & Flanges – for high-pressure applications
Gearbox Housings – for heavy-duty transmission systems
Benefits of Sand Casting for Industrial Use
1. Cost-Effective for Complex Shapes
Sand molds are inexpensive to produce, especially compared to permanent molds or die casting, making it ideal for prototyping and complex part geometries.
2. Flexible Size and Volume
Castings can range from a few kilograms to several tons, with flexible batch sizes—from small series to thousands of pieces annually.
3. Material Versatility
Supports various ferrous and non-ferrous metals (cast iron, ductile iron, carbon steel, stainless steel).
4. Ease of Customization
Simple to adapt design changes; ideal for OEM parts based on customer drawings or samples.
5. Good Machinability
Sand castings can be easily finished with machining, coating, or painting for application-ready components.
Sand Casting Process at EATHU
At EATHU, we follow a rigorous process from tooling to final inspection to ensure precision and consistency:
Pattern Making – Wooden, aluminum, or resin patterns created based on your 2D/3D drawings.
Mold Preparation – Green sand or resin sand molds are made based on production needs.
Metal Melting & Pouring – Controlled furnace melting, with temperature and composition checks.
Cooling & Shakeout – Natural or controlled cooling for metallurgical integrity.
Cleaning & Fettling – Removal of sand, risers, and flash.
Inspection & Testing – Includes visual inspection, dimensional measurement, chemical composition, and mechanical testing (UT, MT, etc. if required).
Materials We Cast – For Industrial Reliability
| Material | Description | Common Uses |
|---|---|---|
| Grey Cast Iron (HT200/HT250) | Good compressive strength, excellent damping | Machine bases, housings |
| Ductile Iron (QT450/500/600) | High tensile strength, impact resistance | Valves, pumps, pressure parts |
| Carbon Steel (WCB, ZG230-450) | Tough and weldable | Flanges, brackets, load-bearing parts |
| Stainless Steel (CF8, CF8M) | Corrosion-resistant, heat-resistant | Food-grade, marine, water systems |
