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.

A method of manufacturing an iron type golf club head with a cavity. Other embodiments are disclosed.

A process of compressing a slug to have tapered ends, then reforming the slug to change the configuration to a shorter length with a larger diameter across the center of the slug. The slug is then reformed and a hole pressed there through, with the pressing of the partial hole reforming the configuration to have a near perfect radius with a hole through the slug, whereby a near prefect ball is made, and the ball has a hole there through.

A process for producing a component from a TiAl alloy by two-stage isothermal forging and to a component produced thereby. The process comprises a first isothermal forging of a component precursor at a temperature of at least about 1180 C., an intermediate annealing of the forged precursor at a temperature ranging from about 1130 C. to 1170 C. for about 1 to 8 hours and a subsequent second isothermal forging at a temperature of at least about 1180 C. with a degree of forming which is lower than the degree of forming in the first isothermal forging.

A forge and method of forging is provided. The forge converts an asymmetric railroad rail to a symmetric railroad rail through a combination of vertical and horizontal forging operations. The rail is linearly translated to heating and forging stations on a roller table. The asymmetric to symmetric conversion can be completed without the need for reorienting the rail except along a single translational axis.

A multidirectional synchronous punch-forming forging machine includes an upper mold and a lower mold which is provided with multiple punching mechanisms at a side surface. A support is rotatably provided at the lower mold, and at least one punching mechanism is mounted on the support. The punching mechanism mounted on the support rotates about a lower mold cavity of the lower mold. Multiple punching mechanisms are provided at the side surface, and the punching mechanisms are configured to be movable, so that a valve body piece can be quickly formed and various valve body pieces can be adapted to.

A method for automatic pass schedule calculation during forging, in particular radial forging, of stepped shafts made of metal workpieces, in particular steel, in a forging machine, preferably a radial forging machine with at least four forging tools arranged around the circumference of the workpiece, which are set up and adapted for simultaneous forging the workpiece and/or the stepped shaft, includes: entering starting parameters for the forging process, preferably radial forging process, into a pass schedule calculation program; specifying target parameters for the forging process, preferably radial forging process; and calculating, by the pass schedule calculation program, based on these start and target parameters, a pass plan or calculated a forge sequence. A control and/or regulation unit and a forging machine for carrying out the method are disclosed.

Radial forging of long products made of metal workpieces in a radial forging machine uses at least four forging tools arranged around the circumference of the workpiece, which are set up and adapted to simultaneously carry out the forging operation. An automatic pass schedule calculation includes entering start parameters for the radial forging process into a pass schedule calculation program and defining target parameters for the radial forging process. The pass schedule calculation program calculates a pass schedule or a forging sequence based on these start and target parameters. The pass schedule calculation program determines a temperature variation and the temperature distribution over the cross section of the long product and takes into account the change in shape during radial forging.

A stock lifter for metal forming dies includes a self-contained assembly. The assembly includes a guide pin that reciprocates within a base. A hardened end cap, which contacts the stock, is attached to the guide pin. A spring is located on the exterior surface of a portion of the base and surrounds the guide pin body. One end of the spring contacts a surface on the cap, while the other end of the spring contacts a surface on the base or an optional mounting flange that is attached above the base. Thus, the stock lifter assembly has a hardened cap for the stock to slide on and a larger, externally mounted spring that provides longer life for the stock lifter. The stock lifter assembly can be made of several different lengths and sizes by using longer or wider guide pins and springs.

The disclosure describes example systems and techniques for controlling microstructure of a superalloy substrate by controlling temperature during forging and using multiple die forging stages to formation of grain boundary phases of the superalloy, and components formed by such example systems and techniques. The method includes heating a substrate to within a forging temperature range. The substrate includes a nickel-based superalloy, and the forging temperature range is below an eta phase solvus temperature of the substrate. The method includes applying a plurality of die forging stages to the substrate to form a component preform. The method includes maintaining the substrate within the forging temperature range during application of the plurality of die forging stages and cooling the component preform.
