2. Sand casting - Wikipedia

   en.wikipedia.org/wiki/Sand_casting

   Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand—known as casting sand—as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries. In 2003, over 60% of all metal ...

3. Flask (metal casting) - Wikipedia

   en.wikipedia.org/wiki/Flask_(metal_casting)

   The bars help support the sand through the molding and pouring operation. Flasks are designed with an alignment or registration feature, so that the two flasks can be aligned to one another to ensure a casting can be more dimensionally accurate and also in small flasks, so that they cannot be fitted together the wrong way.

4. Sand rammer - Wikipedia

   en.wikipedia.org/wiki/Sand_rammer

   A sand rammer is a piece of equipment used in foundry sand testing to make test specimen of molding sand by compacting bulk material by free fixed height drop of fixed weight for 3 times. It is also used to determine compactibility of sands by using special specimen tubes and a linear scale.

5. Core (manufacturing) - Wikipedia

   en.wikipedia.org/wiki/Core_(manufacturing)

   A core is a device used in casting and moulding processes to produce internal cavities and reentrant angles (an interior angle that is greater than 180°). The core is normally a disposable item that is destroyed to get it out of the piece. [1] They are most commonly used in sand casting, but are also used in die casting and injection moulding.

6. Sand slinger - Wikipedia

   en.wikipedia.org/wiki/Sand_slinger

   A stationary sand slinger is a type of machine used for filling and uniform ramming of sand in casting molds, and is particularly advantageous with large molds.This machine consists of a heavy base, a bin or hopper to carry sand, and a bucket elevator to which a number of buckets and a swinging arm are attached, which carries a conveyor belt and the sand impeller head.

7. Pattern (casting) - Wikipedia

   en.wikipedia.org/wiki/Pattern_(casting)

   In casting, a pattern is a replica of the object to be cast, used to form the sand mould cavity into which molten metal is poured during the casting process. Once the pattern has been used to form the sand mould cavity, the pattern is then removed, molten metal is then poured into the sand mould cavity to produce the casting.
