Sand casting









Sand casting is used to make large parts (typically Iron, but also Bronze, Brass, Aluminum). Molten metal is poured into a mold cavity formed out of sand (natural or synthetic). The processes of sand casting are discussed in this section, include patterns, sprues and runners, design considerations, and casting allowance.
 
The lowest cost method for making bulk parts which do not require tight tolerances. Applications include bases, housings, and brackets.  More precise dimensions can be achieved by a secondary machining operation. 
 
Sand castings generally have a rough surface sometimes with surface impurities, and surface variations.

Materials:
Grey cast iron, nodular cast iron, malleable cast iron black-and-white, special and high quality steel, unalloyed and alloyed steel (stainless and corrosion-resistant, heat-resistant, wear-resistant) acc. to DIN, EN, ISO, ASTM, BS, JCSI.
Weight per piece:
Depending on casting process 0,2 kg up to more than 1,000 kg.
