  Forging Operations The five steps of impression die forging are: Heating. Pre-forged metal starts with metal blocks called "ingots," which come in a variety of shapes and sizes depending on the part or component to be produced. ... Preforming. ... Finish Forging. ... Cooling. ... Finishing.

  Different Types of Sheet Metal Operations and Their Uses 1. Shearing                Shearing is similar to what the name suggests—cutting through a sheet of metal in a straight line or curve. It is a manufacturing process used to cut off a plate needed for a particular application, usually done with a shearing machine. 2. Punching           Punching is a process where manufacturers cut holes in the metal. Most often, punches cut the holes shaped like circles or squares. It’s also an excellent way to apply an edge or border to the sheet. 3. Perforating           Perforating is the process where manufacturers put holes in the metal. Also known as punching operation, it is accomplished using a specialized tool called a press hammer. Unless the press hammer punches the hole on the sheet, it doesn’t count as perforating. 4. Notching           The...

  Lamont Boiler:  Lamont boiler is a forced convection boiler. It is a vertical furnace water tube boiler in which the water flows inside the pipe tube and fire or flue gases surround them. Today we will study Definition, Parts, Working Principle Diagram, Application, Advantages, and Disadvantages of Lamont Boiler. So let’s start with the definition first, Lamont Boiler Definition: Lamont boiler is a type of water tube boiler in which steams are generated from water by the burning of fuel which is coal and later that steams are used for the generation of electricity and so on. It is a  high-pressure boiler . Lamont Boiler Parts or Construction: A  Lamont boiler consists of the following parts or construction  as you can see in the diagram below: Feed Pump Grate Economizer Circulating Pump Distributing header Radiant Evaporator Convective Evaporator Steam separating drum Superheater Blower Air preheater  and Combustion chamber Let’s start one by one, Feed Pu...

The pump and compressor is a mechanical component. In this article we will study differences between Pump and Compressor  in detail. Before moving to our main topic we will see definition of these two first, What is a Pump? A Pump is a device used for transferring the liquid to another place from one place. For example In Hydro Plant the water from the head pond to the turbine blade, Pump is used for moving the fluid. The pump is basically used in hydraulic machines to lift the water from the ground surface to the topmost position. There are two types of Pump: Positive Displacement Pump and Dynamic Pump What is Compressor? Compressor is also a mechanical component in which the compressed gases are stored and supply when needed. From Compressor we supply compressed gases to vehicles like motorcycle, 4 wheeler and so on. Different types of Compressor are: Axial Compressor. Centrifugal Compressor. Rotary Screw Compressor. Reciprocating Air Compressor. Difference between Pump and Compr...

What is the Definition of Punch Press Machine?   A punch press machine is used in the deformation of metal by applying pressure to the die attached to the workpiece.  The main functions of the punch press are punching, notching, piercing, slotting, and perforating. The punch press uses its transmission structure to produce appropriate pressure and kinetic energy near the bottom dead center along with the die resulting in plastic deformation of the workpiece according to the desired shape.  A punch press is used when the raw material is too hard to cut manually. Then a manufacturer may use a punch press.  The principle of punch press working is converting the circular motion into the straight-line movement.  It can be small and manually run or, it can be a large CNC-operated automatic machine.  Did you know? The paper punching machine you use daily works on the same principle.  Now moving to different parts of this machine, Parts or Construction ...
