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.

A pattern is a replica of the final part, slightly oversized to account for metal shrinkage during cooling.
It is usually made from wood, palastik, atawa logam.
The pattern is placed inside a molding box (flasas), jeung 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 sprue jeung 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, lalawanan korosi, beurat, jeung ongkos.
These metals contain iron and are commonly used for high-strength and structural applications.

Sand casting’s versatility and low tooling cost make it ideal for a broad spectrum of applications—from heavy industrial components to artistic pieces:
Blok mesin, huluna silinder, brake drums, housings transmisi, suspension knuckles, and railway wheels.
perumahan pompa, awak klep, gearbox casings, compressor shells, and large machine bases.
Pump and compressor internals, refinery equipment housings, piping tees, sikur, jeung flanges.
Propeller hubs, rudder stocks, sea-water valve bodies, deck fittings (cleats, chocks), and anchor components.
Excavator buckets, bulldozer blades, crane sheaves, and structural castings for mining gear.
Turbine casings, steam-generator housings, pump volutes, and hydropower turbine parts.
Tractor housings, plowshares, combine-harvester components, and irrigation pump assemblies.
Statues, relief panels, fountains, ornamental railings, and façade elements.

Sand casting is a metal-forming process where a pattern creates a cavity in a sand-binder mixture, into which molten metal is poured.
Saatos solecification, 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 (alumunium, perunggu, kuningan, tambaga, séng, jeung magnésium).
Typical dimensional tolerances are around ± 0.5 mm per 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.
