发明名称 Method for production of archery bow risers of various shapes
摘要 A method of producing a set of archery bow risers having a variety of shapes is taught in which a workpiece is designed having a shape that encompasses each one of the variety of shapes. A set of dies is produced for producing the workpiece and the dies are used to form a set of workpieces via forging, die-casting or composite resin/fiber molding. Finally, a set of bows having mutually different shapes are machined from the workpieces. The method taught avoids the expense of producing a new set of dies for each new archery bow riser design.
