Extrusion Process Principles Extrusion process is very common in the plastic industry. It is used for high volume plastic production. In extrusion process the color pigments along with other performance enhancing additives are combined with resin which is then pushed through the rotating screws. The heat and pressure generated within the barrels of screw is dispersed and melts the plastic

Die casting process is very different from sand casting as the mould used here is permanent. The mould is not expandable and need not to be broken after the cooling and solidification. Here the mould is called the die. Please Read : Comparison of different casting process A complete Guide to casting process Gravity die casting: When the molten is metal is poured under a gravity

Sand casting: In sand casting which is also known as sand molded casting, an object is produced by sand mold. The process involves pouring of the molten metal in to the mold cavity. The molten metal is then cooled to the room temperature. The metal is solidified. After cooling, the metal object is separated from the mold. Sand casting process has its advantages and disadvantages. So care

EDM is a non-conventional machining technique uniquely used for cutting metals which are not possible to cut with traditional methods. EDM only works with materials which are electrically conductive. Delicate cavities and intricate contours which are difficult to produce with a grinder or other machines can be done with Electrical Discharge Machining or EDM. The cutting tool for EDM may be made

In this process the material of the workpiece is removed by the repetitive impact actions of abrasive particles. The erosion takes place by the abrasive particles which are carried by a liquid medium in the from of a slurry . A shaped vibrating tool is used to produce the impact. The term shaped is used to explain that the process is capable enough to create 3D profiles in correspondence to the

Like all joining processes (in fact, like all processes!), welding offers several advantages but has some disadvantages as well. The most significant advantage of welding is undoubtedly that it provides exceptional structural integrity, producing joints with very high efficiencies. The strength of joints that are welded continuously (i.e.,full length, without intentional skipped areas) can easily

Magnetically impelled arc butt (MIAB) welding (sometimes referred to as rotating arc welding) is a rapid, clean, and reliable arc welding process that employs forging to produce the finished weld. As such, it is classified as an electric arc welding process since that is the energy source for producing melting or fusion, even though pressure from forging is needed to complete the weld. It is

Abrasive Jet Machining (AJM) Principles In abrasive jet machining process, a focused steam of abrasive particles (of size 10 to 40 microns) carried by high pressure gas or air at a velocity of about 150 to 300 m/sec is made to impinge on the work surface through a nozzle, and the work material is removed by erosion by the high velocity abrasive particles. The inside diameter (ID) of the

Gas-tungsten arc welding (GTAW) uses a permanent, non-consumable tungsten electrode to create an arc to a workpiece. This electrode is shielded by an inert gas, such as argon or helium (or a mixture of the two), to prevent electrode degradation; hence the older, common names tungsten-inert gas (TIG) and heli-arc welding. As shown in Figure below, current from the power supply is passed to the

Aluminotherrnic welding is commonly known as Thermit welding. As a subset, these processes use the heat from highly exothermic chemical reactions of solid, particulate materials (or, occasionally, solid particles and a gas) to produce melting and joining, also called coalescence, between metals. Most often, the reactants employed are oxides with low heats of formation and metallic reducing

Welding is an art. There are different types of welding methods. TIG or Tungsten Inert Gas Welding is technique for great welded joints. TIG or Gas Metal Arc Welding (GMAW) needs some great craftsmanship to master. And for this reason we need some decent welding machine from a renowned company. Miller TIG Welder is great when it comes to weld an accurate and clean weld. Please Read : Miller

There is improvement on the sound level. So there is significant improvement in the jobsite communication as a result a safer and more efficient working environment is guaranteed. Miller bobcat 250

If it is assumed that a single process is good enough to approach practical problems in production then it is a total non-sense. There are a lot of methods useful for manufacturing goods. The most difficult part is selecting the right method of production. For manufacturing a product one should bear in mind its appropriate configuration, financial conditions and adequate supplies of materials and

Mild steel is the most commonly used steel. It is used in the industries as well in the different everyday objects we use. Even the pans and spoons of the kitchen are sometimes made of mild steel. The main target of this article is to discuss about different mild steel properties. The mild steel is very important in the manufacturing of metal items. Almost 90% steel products of the world is made
