Precision sand casting is a popular method used by foundries to create high-quality metal components with a level of precision and accuracy that is unmatched by other casting methods. The process involves the use of a sand mixture to create a mold in which molten metal is poured. The result is a solid metal component that is durable and has excellent dimensional accuracy.
At our manufacturing facility in China, we specialize in producing precision sand castings that meet the highest quality standards. Our manufacturing procedures have been designed to ensure that our customers receive the best products possible, and we continually invest in new technology to improve our processes even further.
One of the most significant advantages of precision sand casting is its ability to produce complex geometries with excellent surface finishes. This attribute makes it ideal for the production of components with intricate shapes and patterns, such as engine blocks, turbine blades, and pump impellers. Our precision casting process allows for tight tolerances, which ensure that the final product fits precisely into its intended application.
Our precision sand casting process begins with the creation of a pattern or model of the component that needs to be produced. This pattern is then used to create a mold, which is made by packing a sand mixture around the pattern. Once the mold is created, it is opened, and the pattern is removed, leaving behind a cavity into which molten metal is poured.
Once the metal has cooled and hardened, the sand mold is broken apart, and the cast component is removed and cleaned up. Our precision casting process ensures that the final product has excellent surface finish, dimensional accuracy, and mechanical properties.
There are many advantages to using precision sand casting over other casting methods. Some of the key advantages include:
1. Complex geometries and intricate designs can be produced with ease.
2. The final product has excellent dimensional accuracy and surface finish.
3. The process is highly repeatable, ensuring that each component produced is of the same high quality.
4. Cost-effective for large volume production.
5. Suitable for a wide range of metals, including aluminum, iron, steel, and bronze, among others.
We work closely with our customers to ensure that their requirements are met accurately, from design through to final component production. Our team of skilled technicians and engineers use the latest technology and equipment to produce the best possible products for our customers.

Principle :
In "sand casting", first place the lower half of the mold on the flat plate, put the sand in the sand box and fill it with sand to level it. After the lower mold is formed, turn the formed sand mold 180 degrees, put the upper half of the mold, sprinkle the parting agent, and put The upper sand box is filled, compacted and leveled, the upper sand box is turned 180 degrees, the upper and lower halves are taken out respectively, and the upper mould is turned 180 degrees and the lower mould is closed. This process is commonly known as "sand turning".
Process :
precision sand casting is a production method in which molten metal is poured into the cavity of the mold, cooled and solidified to obtain the product. In the process of automobile manufacturing, there are many parts made of cast iron, accounting for about 60% of the weight of the whole vehicle, such as cylinder block, transmission case, steering gear housing, rear axle housing, brake drum, various brackets Wait.
1. Sand molds are usually used to manufacture iron castings. The raw material of sand mold is mainly sand, which is mixed with binder and water.
2. The sand mold material must have a certain bond strength so that it can be molded into the desired shape and can resist the erosion of high-temperature molten iron without collapsing. In order to form a cavity in the sand mold that matches the shape of the casting, a model must first be made of wood, which is called a wood mold.
3. The volume of the hot molten iron will be reduced after cooling. Therefore, the size of the wooden mold needs to be increased according to the shrinkage rate on the basis of the original size of the casting, and the surface that needs to be machined is correspondingly thickened.
4. Hollow castings need to be made into sand cores and corresponding core wood molds (core boxes). With the wooden mold, the cavity sand mold can be made. When making sand molds, it is necessary to consider how to separate the upper and lower flasks to take out the wooden mold, and also consider where the molten iron flows in and how to fill the cavity to obtain high-quality castings.
5. After the sand mold is made, it can be poured, that is, pour the molten iron into the cavity of the sand mold.
6. When pouring, the temperature of molten iron is 1250~1350 degrees, and the temperature is higher when smelting.
7. Then it has to go through the process of sand removal, repair, grinding, etc., before it can become a qualified casting.
