Effect of Casting Mould on Mechanical Properties of 6063 Aluminum Alloy 91 Journal of Engineering Science and Technology February 2012, Vol. 7(1) The moulds for casting test samples were made from CO 2, cement, naturally bonded sand and metal (hardened steel) moulds.
Die casting dies Gears Plungers and cylinders Abrasive wheels Plastic mould parts Spindles Extrusion screws and barrels Case hardening The case hardening (or) surface hardening is the process of hardening the surface of metal, often low carbon steel, by .

same casting machine and modifications in the casting cell have been implemented. Two casting trials have been performed to set the optimum casting parameters, mainly those related to the cycle time. At the end, a total cycle time of 330 seconds has been set with the molten aluminum introduced at 745ºC.
A metal made by combining different types of metals is called an alloy. Alloys are made to increase a metal's strength, to make it more resistant to corrosion and wear to make it lighter and even to change its color. To make it lighter and even to change its color. To make alloys, a metal is melted down and combined with other metal.
analyze the process of fill in die casting and presents relations that can be used to predict the conditions under which the quality of the product, in terms of defectfree process, can be greatly enhanced. The squeeze dies casting process or the LPDC/ HPDC of molten nonferrous metal .
machines, a diecasting process in which a piston is driven through a reservoir of molten metal injecting the molten metal into the die cavities. It is critical to use only high purity (+ %) aluminum and zinc based alloys in order to obtain and maintain a casting's material integrity, meaning wholeness or .
by first preheating the casting to 1500 deg. F. The casting will be bright red in color. Cast iron melts at approximately 2400˚ F so there is 900˚ between the preheat and melting point of the cast iron. The welding is done with an acetylene torch and bare cast iron rod which is just a stick of clean cast iron as the filler metal.
in 1568, which was driven by a cord passing over a pulley above the machine. This in turn drove two other pulleys on the same shaft which rotated the workpiece and a crude, wooden lead screw, which in turn allowed the operator to remove metal from the piece being machined. The screw cutting lathe originates in the 17th century.
Vacuum diecasting, though expensive, improves casting quality – the metal is degassed by putting it under vacuum before casting. (b) In sand casting, the mould may be damaged by rapid metal flow, releasing sand into the casting and causing loss of dimensional accuracy of the casting.
continuous casting hall in the technological flux (which causes heat losses of the liquid metal from the ladle, until positioning it above the continuous casting machine). The ideal solution would be
