Sand Casting

When is sand casting process more competitive than other casting methods?

Sand casting is more competitive when producing parts that are larger, but with complex shapes. Its mold is relatively simple and better for small batch production and rapid prototyping compared to investment casting. Additionally, sand casting is flexible that it can work with a variety of metal alloys.

How to deal with internal voids and pores in parts for sand casting manufacturers?

Internal voids and pores are common problems during the sand casting process. To reduce these defects, there are several actions such as improving the venting performance of the sand mold, controlling fluidity and the temperature of the liquid metal, and using appropriate pouring method. Additionally, quality control like non-destructive testing of castings can detect potential internal defects.

How environmentally friendly is sand casting process?

Sand casting is generally a environmentally friendly casting method. QFCM stands out in this respect as we use renewable sand material as the mold, which can be reused repeatedly. Additionally, discarded sand molds can be recycled and reprocessed.

QFCM continues to take actions to minimize their impact casting waste on the environment.

What key factors influence the engineering design of 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.
