Advantages of Sand Casting:
When should you choose sand casting? When you have a design for a metal part and your requirements are:
Low tooling costs
Low or high volume requirements
Low part cost
Quick delivery or turn around
Sand casting is a smart choice.
Some distinct advantages of sand casting include:
Sand casting imposes few restrictions on product shape. The only significant exceptions are the draft angles that are always needed on flat surfaces oriented perpendicular to the parting line. With good patterns and tooling, the proper choice of molding sands and careful foundry practice, surprisingly intricate details can be reproduced in this manufacturing process.
Dimensional control and consistency in sand castings ranges from about ±0.030 to ±0.125" (± 0.8 to 3.2 mm) depending on the size and design of the parts being cast. Within this tolerance range, the more generous tolerances apply across the parting line.
Surface finish ranges between approximately 300 and 500 gin (7.7 - 12.9 gm) rms. Various finishes can be applied and they are: Shot blast finish, painted, powder coated, plated (chrome and others), various special coatings such as Rilsan.
Sand casting is relatively inexpensive compared to other manufacturing processes. The process is quite simple and most any metals can be used. Parts can be used as is or can be machined.
Sand casting is acceptably precise and above all, highly versatile. This process can be applied to simple shapes as well as castings of considerable complexity, and it can be used with all metals such as cast and ductile irons, copper alloys, steel alloys, stainless alloys, other complex metals.
Sand casting also lends itself to low volume production or high volumes
