Dawang Factory is dedicated to high-quality production in Sand Casting processes. To achieve this, we employ a variety of quality control measures, including Coordinate Measuring Machines (CMM), Magnetic Particle Testing (MT), Radiographic Testing (RT), X-ray inspection, non-destructive testing, as well as tensile strength and impact testing. These comprehensive inspection methods ensure precision and reliability in the dimensions and quality of each part, along with their performance in tensile and impact resistance, providing our customers with outstanding product quality and reliability assurance.
Dawang Factory takes pride in its excellence in mold quality within the field of Sand Casting. We understand the critical role that sand casting molds play, particularly in the production of large components. We employ high-quality iron molds or aluminiumto molds ensure exceptional surface precision in the casting of large parts. We have very precise control over the internal complex mechanisms of molds used for large castings, which also addresses the needs of many customers for large and complex castings.
Sand casting process 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 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 casting processes for manufacturing large castings.

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.
Internal voids and pores are common problems during the sand 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.
Sand casting is generally considered a relatively environmentally friendly casting method. Especially, Dawang uses renewable sand material as the mold that can be reused many times. Additionally, discarded sand molds can be recycled and reprocessed. Dawang continues to take actions to minimize their impact on the environment, as there are still environmental considerations for sand casting manufacturers in terms of the waste and wastewater treatment generated during the sand casting process.
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.
