Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting materials are usually metals or various time setting materials that cure after mixing two or more components together; examples are epoxy, concrete, plaster and clay. Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods. Heavy equipment like machine tool beds, ships' propellers, etc. can be cast easily in the required size, rather than fabricating by joining several small pieces.

Lost wax investment casting can produce a variety of complex and intricate parts with excellent tolerances. Lost wax investment casting is used to produce parts that require tight tolerances with thinner walls and exceptional surface finishes that require very little after process finishing.

Sand casting can be readily produced in nearly any ferrous or non-ferrous alloy. Some other casting processes will melt and pour super-alloys in a vacuum, but that is not typically done as a sand casting. Some materials cannot be “worked”, and must be produced as a casting. The relatively low cost of tooling makes sand casting a process of choice for lower volume needs. Patterns do wear so the material selected for the pattern (typically wood, plastic, or metal) will depend on the expected usage quantity of the part being produced. Though not necessarily cheaper in the short run, the use of machined (or “patternless”) molds may be a cost-effective option for components with expected lower usage over a longer period of time.

Die casting is the foundry production process thanks to which a metal, such as aluminum, is injected at high pressure into a metal mold and finds its permanent shape. The advantages of aluminum die casting are many, some of which are a consequence of the characteristics of the material. The advantages of aluminum are lightness, resistance to corrosion, thermal and electrical conductivity, workability and recyclability, and are added to the die-casting process, which guarantees further qualities. Some advantages of aluminum die casting concern the final product, others the production process.

Forging refines the grain structure and improves the physical properties of the metal, so that the grain flow can be oriented in the direction of principal stresses encountered in actual use. Physical properties such as strength, ductility, and toughness are much better in a forging than in the base metal.

We usually say the strength of products will be increased after closed die forging, as the steel billet is shaped during the forging process, its internal grain deforms to follow the general shape of the part. As a result, the grain is continuous throughout the part, giving rise to a piece with improved strength characteristics. Higher strength will help to increase the working performance of products, thus to longer the serving time. That is why closed die forging is always applied in most applications.

Smith forging is the same which a village blacksmith uses for making various tools. In smith forging the heated metal gets repeated blows of hammers to get desired shape.

CNC machining delivers superior accuracy, precision and speed for high quantities of product, and that makes it the right choice in most situations. Businesses in competitive industries gain an edge through efficiency and consistency, as well as precision and accuracy.

CNC lathe is simple to set and easy to operate. It primarily helps to implement the innovative methods of manufacturing, in order to obtain the maximum benefit of the latest technology. The machine components are preset and the tool paths are pre-planned by the CAD and CAM processes. The programmed file is then tested and loaded on the machine. The operator thereafter issues the related commands to activate the necessary parts of the machine.

Today, machining center processing is widely used in manufacturing sites. Machining centers are critical equipment for machining metal parts and components in addition to their primary purpose of die manufacture. As an example, machining centers in the automobile industry are used for efficient grinding and drilling of engine parts as well as for making dies for body components. Many other products commonly used in daily life and in industrial settings are manufactured in machining centers. Machining centers feature a computerized automatic tool change function. In general, an operator must exchange the tools on an NC machine tool. Machining centers, however, have a change arm that automatically retrieves and exchanges tools from a tool magazine where the tools are stored during the machining of workpieces. This saves time and effort required for standard tool changeovers, and consequentially enables automated and power-saving operations while reducing costs.
