 · Sand casting is a process that utilizes non-reusable sand molds to form metal castings. On one hand, casting is a deceptively simple manufacturing process: anyone who has formed castles at the beach knows sand can be used to make detailed shapes. However in a foundry, dealing with the heat of molten metal, many factors must be considered for

Microstructure and hardness improvement. The morphology of the nitrided layers depends on the core microstructure resulting from the transformation of chromium carbides into chromium nitrides. Although this microstructure must be stable during the nitriding treatment, the core hardness decreases by 20–30 HV if either the tempering

Type C: Suitable for the surface hardness test of sand mold in high pressure molding. * The unit of type B hardness tester for sand mold surface is (g/mm 2), but it is customary to use hardness H(A/B/C) instead of unit. Because their values are related and consistent, the corresponding hardness value is also large when the unit value is large

Foundry sand testing is a process used to determine if the foundry sand has the correct properties for a certain casting process. The sand is used to make moulds and cores via a a sand casting foundry there are broadly two reasons for rejection of the casting — metal and sand — each of which has a large number of internal variables.

reflects the degree of temper of the sand mix. Procedure - The test is run by filling a standard specimen tube ( in. high, 2 in. around) with riddled sand through a -in. screen mounted at a constant height above the tube. The excess sand is struck off the top of the tube, and the sand is rammed three times. The distance from the top

A core is a sand or metal insert used to shape any part of a casting that cannot be shaped by the primary removable pattern. When a pattern is pressed into sand and then extracted it leaves a concave impression. Liquid metal fills this void and cools. Cores are created to allow more complexity in the design. Well-constructed cores create holes
