Abstract: A method of producing a bow holding handle by providing a first mold cavity in the same shape as said bow holding handle but in smaller size; placing required parts of said bow holding handle in corresponding positions of said first mold cavity; sealing said first mold cavity; injecting liquid foam plastic into said first mold cavity; activating said plastic foam to cause expansion thereof and form a core of said bow holding handle as the same shape of said first mold cavity; removing said core away from said first mold cavity; wrapping said core with a plurality of layers of fiber reinforced plastics; providing a second mold cavity shaped in the form of said bow holding handle; inserting said wrapped core into said second mold cavity; sealing said second mold cavity; heating said second mold to cure said layers of fiber reinforced plastic and to cause re-expansion of said core for generating pressure within said second mold cavity pressing said core against said layers of fiber reinforced plastic and thereby
