The sizing operation is a squeezing operation that minimizes the thickness of the metal. Sizing is performed in an open die and only the surface where the die and workpiece touch will be sized. Many ferrous metal castings are sized to sharpen corners and flatten holes around piercings. Sizing pressure is determined by area to be sized, the ...
In metallurgy, cold forming or cold working is any metalworking process in which metal is shaped below its recrystallization temperature, usually at the ambient temperature.. Such processes are contrasted with hot working techniques like hot rolling, forging, welding, etc. [1]: p.375 The same or similar terms are used in glassmaking for the equivalents; for example cut glass is made by "cold ...
Blanking is the operation of cutting flat shapes from sheet metal. The outer area of metal remaining after a blanking operation is generally discarded as waste. Size of blank or product is the size of the die & clearance is given on punch. It is a metal cutting operation. In blanking, metal obtained after cutting is not a scrap if it is usable.
Drawing is a manufacturing process that uses tensile forces to elongate metal, glass, or plastic. As the material is drawn (pulled), it stretches and becomes thinner, achieving a desired shape and thickness. Drawing is classified into two types: sheet metal drawing and wire, bar, and tube drawing.
Squeeze casting was originally created to make stronger metal parts for use in the construction and defense industries. The metal parts created by this process are more resistant to wear and heat and have historically been very expensive to produce. The market for these parts has grown to include the agricultural and automotive industries.
Over the years alternative variations of the metal stitching processes were developed, they use terms like Metal Stitch, and Metal Locking, and Metalock to describe their repair process. Lock-N-Stitch [ 6 ] is a slightly different stitching method, that was developed from the original stitching concept, by Gary J Reed.
