Ganesh Narayanan, IITG Bending: In this, the sheet material is strained by punch to give a bend shape (angle shape) usually in a straight axis. Deep (or cup) drawing: In this operation, forming of a flat metal sheet into a hollow or concave shape like a cup, is performed by stretching the metal in some regions.
The recyclable waste we calculate from the cost of raw materials and stuff (we take the specified percentage). For determining of the additional wage we need to take inti account the following dates: if the basic salary is more than 200 that additional one is equaled 10% from the base; less than 200 – 15%...the spot price solely for the purpose of determining the value of raw sugar in the event of a contract default. The New York spot price is the primary basis on which raw cane sugar mills pay independent growers for domestic cane, and it is closely tied to the world price of raw sugar. As a result, the entire structure of pricing refined cane
