Sand Casting
Sand Casting Services in China
Product Details: Sand casting is a metal casting process that involves creating a mold by packing sand around a pattern of the part to be cast. The process includes adding sand with a binder to a molding box, creating mold halves and adding cores for internal cavities, pouring molten metal into the mold, and allowing it to solidify. The final product is recovered by removing the sand through a shake-out process. Sand casting can produce parts ranging from a few ounces to several tons and is suitable for casting ferrous and nonferrous materials.
Pros:
– Low operational costs
– Can cast large parts
– Suitable for mass production at cost-effective rates
– Shorter lead times in production
– Relatively easy to change the design of the mold
– Fast lead time
Cons:
– Low dimensional accuracy
– Rough surface finishes
– Requires extensive secondary machining and finishing
– Cannot produce parts with thin walls or complex internal configurations
– May have defects such as clip sand, sand wash, and gas holes
