Get Pricekens metal industries limited was started as a foundry in 1982 which produced, stocked and supplied cast iron, brass, bronze and aluminium. We were initially a sand casting foundry and a machine workshop. In 1984 we started pressure die casting of brass and aluminium, as well as that a small brass extrusion press was installed.sand casting is a very versatile process and can produce castings of extreme complexity in a wide range of aluminium alloys. interest in light weighting and improvements in the technology of sand casting has driven the average weight and size of aluminium sand castings upward, with many parts weighing over kg and with some parts as large as 100oct 17, 2019 the nature of sand, however, means that the molds used in the process are expendable and non-reusable. It is impossible to keep a sand mold intact when removing a casting. On the other hand, sand casting is ideal for high melting temperatures metals such as titanium, steels, and nickel. It is the only casting method that can handle these materials.engineers have tried the plan of mixing the magnetic sand with resin, making little bricks of it, and then submitting it to the furnace, but none of these plans proved practical; for while in some cases they could indeed separate the iron from the sand proper, and the gold also, the treatment cost so much money as to make it much cheaper to get
