The Quality of CRGO is measured in terms of lower losses of electrical current, which flow in the core. The proper design of core and good quality of core material do a best job in combination. Mainly the core losses are measured in Watts per Kg.

Metal component parts can be stamped for lowest cost and greater efficiency. Very intricate and complex products can be produced using a metal stamping die. This is due to advances in die design and build technologies. Products can be cut, formed, drawn, twisted, coined, extruded, welded, and tapped. Also, parts can be assembled in the die by employing a variety of technologies. As a result, the metal stamping process economically competes with other processes such as chemical etching, laser cutting, screw machining and die casting, even at low production quantities.

n die casting, molten metal is injected into a mold at high pressure. The pressure can range from about 1,400 psi to as high as 30,000 psi. By pressurizing the mold, the cast object will be more uniform and will display an attractive finish. In many cases very little or no post-casting machining is needed to complete the item. Pressure molding also provides for precise dimensional accuracy that is critical for parts used in products with interchangeable parts. Low pressure die casting is commonly used for larger non-critical parts. Whereas high pressure castings which are used for tight tolerance detailed geometry. High pressure die castings are able to maintain tighter tolerances and more detail than low pressure die casting because the extra pressure utilized is able to push the metal into more detailed features in the mold. High Pressure die castings have excellent surface finishes that are consistent dimensionally with precision features and minimum draft. There are two main die casting processes, and their use is dependent on the type of metal being cast:

Core laminations are the main part of an electrical transformer, and this attribute to 70% of a transformer cost. These core laminations are required to be cut from special steel called as Cold Rolled Grain Oriented Electrical Steel or popularly known as CRGO. The CRGO is a special quality of steel which have a special grain surface and comes in a thickness of 0.23 mm, 0.27 mm, 0.30 mm, 0.35 mm. (generally called M3, M4, M5 & M6). Lower the thickness of material better is the quality of material. The Quality of CRGO is measured in terms of lower losses of electrical current, which flow in the core. The proper design of core and good quality of core material do a best job in combination. Mainly the core losses are measured in Watts per Kg. Every type of steel has "grains" which consist of "domains". These "domains" are nothing but electrical charges oriented in any random direction. Therefore if a transformer were to be made of Mild Steel used as core material, the core loss would be approx. 16 to 17 wkg at 1.5T50Hz and the size of the transformer would be approx. 18 to 20 times the size of a transformer manufactured with GO steels.

ELECTRICAL STEEL : Electrical Steel, also called lamination steel, silicon electrical steel, silicon steel or transformer steel is speciality steel tailored to produce certain magnetic poperties, such as small hysteresis area (small energy dissipation per cycle, or low core loss) and high permeability. PRODUCTION PROCESS 1) Hot Rolled Coil-> Pre-Annealing and Pickling -> High Temperature Annealing -> Insulation Coating -> PH-Core & PG-Core 2) Hot Rolled Coil-> Pickling -> Cold Rolling -> Annealing -> Tempreture Rollling -> Insulation Coating -> PN- Core & PNS Core 1) CRGO: Core laminations are the main part of an electrical transformer, and this attribute to 70% of a transformer cost.
