Sand Casting is a traditional metal casting process that involves creating a mold from compacted sand, then pouring molten metal into the cavity to form a desired shape.
Once the metal solidifies, the sand mold is broken apart to remove the final casting.
DEZE Technology provides a variety of casting services, and users can choose the appropriate casting process according to their needs.
If you don’t know which casting method is more suitable for your product, please contact us and our professional engineers will help you.
A pattern is a replica of the final part, slightly oversized to account for metal shrinkage during cooling.
It is usually made from wood, plastik, veya metal.
The pattern is placed inside a molding box (şişe), Ve sand mixed with a binder (like clay or resin) is packed around it.
The mold is made in two halves:
Cores are sand shapes inserted into the mold to form internal cavities in the casting.
Molten metal is prepared in a furnace and poured into the mold through a yolluk Ve runner system.
After pouring, the metal is allowed to cool and solidify inside the mold.
Once the metal has cooled, the sand mold is broken apart to retrieve the solid casting.
Excess material such as sprues, risers, and flash are removed by cutting or grinding.
Sand casting supports a wide range of ferrous and non-ferrous metals. The choice depends on the desired mechanical properties, korozyon direnci, ağırlık, ve maliyet.
These metals contain iron and are commonly used for high-strength and structural applications.

Sand casting is a metal-forming process where a pattern creates a cavity in a sand-binder mixture, into which molten metal is poured.
Katılaşmadan sonra, the sand mold is broken away to reveal the finished part.
Nearly any metal can be sand-cast, including ferrous alloys (gray and ductile iron, carbon and alloy steels) and non-ferrous alloys (alüminyum, bronz, pirinç, bakır, çinko, ve magnezyum).
Typical dimensional tolerances are around ± 0.5 MM başına 100 mm of dimension, with surface finishes of Ra 6–12 µm.
Select sand casting for low-to-medium volumes, large or complex parts, rapid prototyping, or when low tooling cost is a priority—even if final parts require some machining.
