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.

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

Applications for Sand Castings

Sand casting is used for a variety of applications to produce a wide range of parts including:

• air compressor pistons
• bearings
• blowers & impellers
• bushings
• cams
• electronic equipment
• engine crankcases
• engine oil pans
• fittings
• flywheel castings
• gas and oil tanks
• gears
• hardware
• low-pressure valves
• machine parts
• mining machine parts
• oil pans
• printing press
• pump bodies
• pump pistons
• screw nuts
• trailer parts
• truck chassis parts
• valves
• water jackets & crankcases
• worm gears
