Billets are a length of metal with round cross section (cylindrical shape) used for extrusion and forging processes in industry. The billet production process is done in two stages: casting stage and finishing stage. At the casting stage, billets are formed through direct casting machines. Each casting unit is connected to three
casting molds is studied with detailed procedure for the casting process as depicted in tomb scenes. The characteristics of each metal-casted artifact are presented. KEYWORDS: History of mechanical engineering, ancient Egypt, metal casting, solid-casting, hollow-casting, Predynastic and Dynastic Periods. Introduction
The metal will harden shortly after casting. Then the metal mold should be broken with an iron hammer. Break the mold and bring out the cast sculpture or object from inside. Metal-chasing Casting channels and air channels should be cut from the body of the sculpture after the mold is broken. Also, if there is anything unnecessary on the casting ...
Low-pressure die cast (LPDC) is widely used in high performance, precision aluminum alloy automobile wheel castings, where defects such as porosity voids are not permitted. The quality of LPDC parts is highly influenced by the casting process conditions. A need exists to optimize the process variables to improve the part quality against …

The casting process is the oldest and most popular method of manufacturing means of designing the desired shapes. It is the first step in manufacturing most products. Casting is made from any type of metal that can be melted and have any shape the designer desires. The castings can produce sizes ranging from a few mm to …
(f) After the casting is obtained, it must be cleaned using air-jet or sand blasting (g) Finally, the extra metal near the gate, risers and vents must be cut off, and critical surfaces are machined to achieve proper surface finish and tolerance. 2.1.2. Shell-mold casting Shell-mold casting yields better surface quality and tolerances.
The castability of high pressure die casting (HPDC) alloys was reported to be principally related to the die temperature, the in-gate velocity of melt, and casting pressure (Kong et al., 2008).It was found that the combination of die temperature, the mould filling capacity of molten metal, the geometrical complexity of parts and cooling rate …
