Product Description
Sand casting process uses the green sand or dry sand to make the molds for casting molten metals. Most of castings are produced by this old but new casting process. Sand casting is one of the most popular and simplest types of casting. Sand casting allows for smaller batches than permanent mold casting and at a very reasonable cost.
Due to its well-suited for complex geometries, sand casting process takes advantage of compact sand, refractory and recyclability to produce relatively less expensive molds with quick tooling development and design changes at a competitive cost. For some desired castings of huge size and weight, the sand casting process is the first choice we should think when we choose the suitable manufacturing methods.
The are several sand casting process based on different mold materials. At our Foundry, we can proceed the sand casting process by green sand casting, pre-coated resin sand casting and furan resin sand casting. The pre-coated resin sand casting is also called shell molding casting or shell casting. The shell casting process has much better surface for the finished castings.
In our high-tech facilities, we offer both automatic machine and manual molding operations in our resin sand casting processes. We can pour gray and ductile iron castings using our no-bake process up to 1 ton finished weight in gray iron castings and ductile iron castings, and up to 0.5 tons in steel castings and stainless steel castings.

How We Inspect the Sand Castings
Our Spectrometer checks 20 chemical elements and metallurgical microscope produces high-resolution images 1,000 times magnified, and our cleanliness meter determines particle size and quantity to ensure materials meet or exceed the international standard. We use ultrasonic detectors to discover flaws, and have X-ray machines and accelerators that can scan castings with 200 mm maximum wall thickness.
Our factory has a full range of inspection capabilities in house, which include:
- Spectrographic and manual quantitative analysis
- Metallographic analysis
- Brinell, Rockwell and Vickers hardness inspection
- Mechanical property analysis
- Low and normal temperature impact testing
- Cleanliness inspection
- UT, MT and RT inspection
Steps of Sand Casting Process
1- Making Pattern
Patterns made of wood, resin (plastic) or aluminium could be used to produce during the casting. Generally, the costs of the aluminum patterns will be the highest, but it is the most suitable process if the customers need thousands of castings with higher dimensional tolerances and better surface quality.
2- Molding Process
The resin sand will be mixed by the sand treatment equipment, then shoot into the sand boxes (flasks). The molding workers will guarantee the sand can be filled to all positions, and make the sand as solid as possible.
3- Self-Hardening of Resin Sand Mold
After molding by workers, the sand is still loose. Then, the sand mold will be coated by a type of alcohols based coating, after burning, the resin sand mold will become very solid. This is why this casting process is called as hard mold casting process, also called as self-hardening sand mold.
4- Melting and Pouring
Just like the sand casting process, medium frequency electrical furnaces are used to melt irons for resin sand casting process.
5- Sand Blasting, Cleaning and Grinding
The shot blasting process is to remove the sand and oxides, then the workers will cut off the gating systems, and grind the gating positions and parting lines. Finally, the rough castings will be completed. If secondary processes like machining or surface treatment are needed, these complete castings will be taken to the next workshops.
What Facilities We Rely On for Sand Casting
We utilize the professional equipment to assemble the automatic casting production lines. We have two production lines for sand casting, the vertical automatic sand casting line and the horizontal automatic sand casting line. These highly organized equipment help us to produce the casting parts of high quality and big volume. These equipment can cast a diverse materials such as grey iron casting, ductile iron casting, carbon steel, alloy steel, stainless steel, aluminium and brass.
