(a) Schematic illustration of the deep-drawing process on a circular sheet metal blank. The stripper ring facilitates the removal of the formed cup from the punch. (b) Process variables in deep drawing. 網頁In the present review, we discuss recent progress in the field of C–Z bond formation reactions (Z = S, Se, Te) catalyzed by transition metals. Two complementary methodologies are considered─catalytic cross-coupling reactions and catalytic addition reactions. The development of advanced catalytic systems is aimed at improved catalyst efficiency, …

網頁A wire or rod of steel, copper, other metals, or alloy enters into one side and is lubricated and reduced in size. The leading tip of the wire is usually pointed in the process. The tip of the wire is then guided into the die and rolled onto a block on the opposite side. The block provides the power to pull the wire through the die. 網頁Metal forming is one of the important manufacturing processes. There are three types of metal forming processes: bulk metal forming, sheet metal forming, and sheet-bulk metal … 網頁Aluminum bronze is heat treatable, is lead free and has the strength of steel.
