Casting


Casting is unlike forging and extrusion in that metal is heated until it reaches a molten state and is then either injected into or poured into a mold in the shape of the desired end product. The molten metal immediately cools in the mold and solidifies into the desired part. Generally, casting is used to produce complex geometrical industrial metal parts. One benefit of casting includes achieving the exact part that is desired because the molten metal flows into the mold and fills it entirely. There is also no limit to the size of the part one is attempting to achieve in sand casting. Casting can be a lower cost option depending on the ultimate use of the final product


Casting is the process of pouring molten metal into a mold or die and allowing it to cool and harden so that it takes the shape of the mold. The process is ideal for mass-production of parts with the reuse of the same mold to create identical products. 

There are several different types of casting. Die-casting is when liquid metal is forced into a die instead of a mold, and there the applied pressure keeps it in place until it hardens. This process is known for the high-speed applications it supports. Permanent mold casting involves pouring the molten metal into a metal mold, using gravity or a vacuum to fill the mold. Permanent mold casting can create stronger castings than die casting, but they can be difficult to remove from the final product. For this reason, semi-permanent mold castings are also available. These molds have expendable cores, making them more manageable and less costly to remove. 

The final casting process is sand casting. With sand casting, castings are made by pressing a pattern into a fine mixture of sand. This forms a mold for the molten metal to be poured into.This process is slow but is generally more economical than the other forms of casting. It is also good to use when intricate designs are needed, or for large metal fabrication. 

Gravity Die Casting (also called permanent mold casting )is the process of pouring molten metal into the mold under the action of gravity. It mainly refers to the metal mold casting.

Forging

Forging is the shaping of hot metal completely within the walls or cavities of two dies that come together to enclose the work piece on all sides. The impression for the forging can be entirely in either die or divided between the top and bottom dies. Impression-die forging, often used interchangeably with the term closed-die forging, refers to a closed-die operation in which the dies contain a provision for controlling the flow of excess material, or flash, that is generated. 


Forging uses compressive force to shape metal. A hammer or die strikes the metal workpiece until the desired shape is formed. The pounding action of forging deforms and shapes the metal, which results in unbroken grain flow, which allows the metal to retain its strength. Ancillary effects of this unique grain flow include the elimination of defects, inclusions, and porosity in the product. Another advantage of forging is the relatively low costs associated with moderate and long production runs. Once the forging tools have been created, products can be manufactured at relatively high speeds with minimal downtime. 

Machining


Precision machining is a process that removes excess, raw material from a work-piece, while holding close tolerance finishes, to create a finished product.  Simply put, it means shaping large pieces of material into more precise parts, so that they can meet very exact specifications. This process involves cutting, milling, turning, and electrical discharge machining, and is generally performed using Computer Numerical Control (CNC) equipment.
