Any setting or unreasonable operation of any link will change the shrinkage rate of the casting, resulting in The dimensional accuracy of castings deviates from the requirements. The following are the factors that can cause defects in the dimensional accuracy of precision castings:

Casting sand, also known as foundry sand, serves as a mold material where molten metal is poured. The most commonly used type is silica sand, but variations such as olivine sand and zircon sand are also utilized depending on the requirements of the casting project. The effectiveness of foundry sand is evaluated based on its grain size, shape, and thermal stability, which impact the outcome of the casting. Thus, sourcing high-quality sand becomes imperative.

- Automobile Les pièces automobiles, comme les carters de moteurs, les jantes et d'autres composants structurels, bénéficient de la légèreté et de la résistance de l'aluminium, tout en respectant des normes de sécurité strictes.

3. Reducing Metal Penetration One of the potential issues in casting is the penetration of molten metal into the sand mold, leading to defects like metal penetration or drop-out of sand particles. Effective facing sand is designed to minimize this penetration, preserving the mold shape and preventing unwanted inclusions in the final product. A well-constructed facing sand layer can create a barrier that helps to ensure a defect-free casting.

Die casting, on the other hand, involves forcing molten aluminum into hardened steel molds. This method is highly efficient for mass production and delivers parts with excellent dimensional accuracy. Die casting is widely used in automotive components, toys, and hardware due to its ability to produce lightweight yet durable products.
