Sand Casting Advantages & Process

Sand casting is the oldest method of casting. It is also the most versatile, has the lowest setup cost, and is the easiest and most cost-effective to modify. Because of these features, sand casting is ideally suited for making low and medium volume production castings and converting welded parts to castings.

Leitelt Brothers Inc. has over 100 years of experience in the design and manufacture of aluminum, brass and bronze castings. We mold craftsmanship and advanced technology together to produce castings that meet the most rigid specifications. LB Foundry is also known for our Green Sand Molding capabilities.

Sand Casting Process

Below are the basic steps in the sand casting process:

• Create a mold by placing a pattern in sand.
• Make a proper gating system in the mold.
• Remove the pattern from the mold.
• Pour molten metal into the mold cavity.
• Allow the metal to cool.
• Break away the sand mold and remove the casting.

Advantages of Sand Casting

In addition to Sand Castings being very versatile, having a low set up cost, and being the easiest and most cost-effective to modify, there are many other advantages as sand casting makes it possible to:

• Form complex shapes
• Produce very large parts
• Have a lower cost for tooling
• Have a shorter lead time
• Recycle scrap
• Use a variety of materials
