Sand Castings Process, Custom Sand Casting Foundry Service Supplier

Sand casting is a great product which could make fantastic staff from virtual to reality.

Sand casting could be used for aviation, weapon, industry, Oil & Gas, Gas Power, ocean engineering, wind onshore and offshore areas.

Sand casting have multiple material like gray iron, ductile iron, steel etc… each materiel also have different type like ductile iron QT400, QT450, QT700 etc.

Sand casting is produced by a traditional process which including sand core, sand molding, melt, pouring, cool down for solidification etc; after the casting is shake out from the mold, we need clean, heat treatment, shoot blasting, machining, coating to get a beautiful sand casting. Besides, inspection across each manufacturing process, and final inspection as per drawing and requirements to ensure a great sand casting!

Types of Different Sand Casting

Sand Casting Manufacturing Process

At Balasen, we master the time-tested sand casting process to produce high-quality metal components with exceptional dimensional accuracy. Our expertise in this traditional yet versatile method ensures reliable results for industries ranging from automotive to heavy machinery.

Our Sand Casting Process:

Pattern & Mold Creation – Custom patterns are embedded in specially formulated sand to form the mold cavity.
Core Making – Sand cores (if needed) are placed to create internal geometries.
Melting & Pouring – Metal alloys are melted at high temperatures and precisely poured into the mold.
Cooling & Solidification – Controlled cooling ensures optimal metallurgical properties.
Finishing – Post-casting processes (trimming, machining, surface treatment) deliver ready-to-use components.

Sand Casting Advantages

Sand casting as a common mechanical product, it has a lot advantages.

Firstly, it could provide pretty good mechanical property to meet client expectations. Good strength,yield, extension, impact property etc… based on client need, we can choose material like gray iron, ductile iron, Carbon steel, Mn steel, Al etc… we can always find a suitable material to generate the sand casting.

Secondly, sand casting can have accurate dimensions. We can fix the basic dimensions by casting process, and then get the precise dimensions including geometry by machining process, finally dimension could be checked by CMM or 3D arm tooling.

Thirdly, sand casting is competitive cost compared to other technical process product.

the material quality like ductile iron, steel etc…which could be inspected by NDT(UT,PT,MT,RT), will be able to ensure a soundness quality of internal material and surface quality.

Fourthly,mechanical property of sample test will be able to control the material quality meet the need.

Overall, sand casting is reliable and a good option.
