Why Choose Us
At present, six automatic double-station core shooting machine sets and two single-station core shooting machine sets are available at Dawang Castings. These machines can produce a variety of castings with an overall dimension of 1000mm x 1000 mm and a unit weight of no more than 100Kg thanks to their 1200mm × 1200 mm maximum tooling installation capacity.
Dawang Castings’s first goal is to ensure the products’ quality. We maintained our reputation by providing the best quality products for decades. However, to reduce the impact of human factors and guarantee product consistency, the production process uses a combination of parameterized control and standardized procedures.
Latest Tooling Facility
Dawang Castings continues to invest in cutting-edge technology to produce increasingly complicated parts for its clients. As a result, we can create any casting, even those with intricate moulds. However, the tooling in Dawang Castings is made of high-quality alloy cast iron, which has a small thermal expansion coefficient, small thermal deformation, good strength, and wear resistance, so the accuracy and consistency of the product are well guaranteed.

Application of Sand Casting
Sand casting is an advanced manufacturing technology. With sand casting we can produce complex, precise metal components. The application of sand casting cover many key industries, including aerospace, automobile, medical equipment, electronic equipment and energy fields.
Sand casting is widely used in these fields. Its advantage is that it is suitable for the manufacture of large and complex parts, and it is relatively simple and low-cost. Therefore, sand casting is one of the important processes for manufacturing large castings.
1.When is sand casting more competitive than other casting methods?
Sand casting is often more competitive when producing parts that are larger, have complex shapes, or require a variety of materials. Its mold manufacturing is relatively simple and suitable for small batch production and rapid prototyping. Additionally, sand casting is an adaptable method that can be used with a variety of different metal alloys.
2. How to deal with internal voids and pores in parts during sand casting?
Internal voids and pores are common problems during the casting process. To reduce these defects, measures are often taken, such as improving the venting performance of the sand mold, controlling the temperature and fluidity of the liquid metal, and using appropriate pouring techniques. Additionally, quality control steps include non-destructive testing of castings to detect potential internal defects.
3. How environmentally friendly is sand casting?
Sand casting is generally considered a relatively environmentally friendly casting method. It uses renewable sand material as the mold and can be reused many times. Additionally, discarded sand molds can be recycled and reprocessed. However, there are still environmental considerations for the waste and wastewater treatment generated during the casting process, so foundries often take steps to minimize their impact on the environment.
4. What key factors need to be paid attention to in the engineering design of sand casting?
There are several key factors to consider when designing a sand casting project, including part geometry, material selection, mold design, cooling system design, and pouring and venting techniques. Engineers typically optimize these factors to ensure the best casting results, including dimensional accuracy, surface quality and material performance.
