The inventive subject matter is directed to continuous electrochemical production of highly pure micro- or nanostructured lead that at least partially encloses the electroprocessing solvent and molecular hydrogen and optional guest compounds to form a mixed matrix. Such compositions are particularly suitable for cold forming of various structures and/or for alloy and composite material production.

Provided is a method for manufacturing an iron golf club head by forging a single round rod member with a pair of dies to form, as a single piece, a body and a neck into which a shaft is to be inserted. The method includes: a first step of heating the single round rod member into a heated material; a second step of placing the heated material in the pair of dies; and a third step of forging the heated material placed in the pair of dies. In the third step, the heated material is prevented from flowing out from parting surfaces of the respective dies at a sole side of the body in the pair of dies, and the heated material blocked at the sole side in the pair of dies flows toward each of a toe of the body and the neck in the pair of dies.

A continuously variable transmission includes: a first pulley having a first fixed sheave and a first movable sheave; a first cylinder forming a first oil chamber with the first movable sheave; a second pulley having a second fixed sheave and a second movable sheave; a second cylinder forming a second oil chamber with the second movable sheave; and a transmission belt wound around the first pulley and the second pulley. The first cylinder has a first member that is fixed to a first shaft and a second member that is joined to an outer peripheral portion of the first member. A bearing is interposed between an outer periphery of the first member and an inner periphery of a case. A thickness, in an axial direction, of a portion of the first member that is configured to directly abut against the first movable sheave is larger than a thickness of the second member.

Provided is a method for manufacturing a stainless steel ball stud for an automotive suspension system, which includes: a forging and molding step of forging and molding a cylindrical shaped stainless material blank with the same top and bottom diameters by using a progressive press machine to operate a number of mold dies simultaneously and to move a forged mold product of a preceding die to a succeeding die, to make a forged mold product; a male thread shaping step of shaping a male thread on the forged mold product; and a cutting and surface finishing/burnishing step of cutting the forged mold product by using one ball stud processing machine such that a head part is cut at exact dimensions, a neck part and a washer part are shaped and the surface finishing/burnishing work to the head part is performed to complete the stainless steel ball stud for an automotive suspension system.

The present invention relates to a method for manufacturing a round-rod shaped alloy ingot by hot forging, containing suspending a primary alloy ingot having a round-rod shape in a columnar mold while one end of the primary alloy ingot is held, pouring a molten metal formed of a heat-retaining metal into the columnar mold so as to apply a coating of the heat-retaining metal to the entire circumference of the primary alloy ingot, to obtain a forging alloy ingot, taking the forging alloy ingot out from the columnar mold, then subjecting the forging alloy ingot to a hot forging while an end portion of the forging alloy ingot is gripped as a gripping portion, and removing the coating of the heat-retaining metal.

A method for manufacturing a blade, the method includes casting a nickel alloy blade precursor having an airfoil and a root. The airfoil and the root are solution heat treating differently from each other. After the solution heat treating, the root is wrought processed. After the wrought processing, an exterior of the root is machined.

A forging device for molten metal includes first and second die bodies that are linked by first and second power arms to move back and forth in a cavity of a die base so as to open and close a workpiece shaping space defined between first and second die faces of the first and second die bodies. When the workpiece shaping space is opened, a molten metal is poured, and then the workpiece shaping space is closed to cast a semi-finished workpiece. After that, the first and second power arms axially press and forge the semi-finished workpiece in the workpiece shaping space into a high-strength workpiece. The high-strength workpiece is shaped by casting and forging in the same process.
