A bird spike is insertion molded, using a technique in which a wire that forms at least one of the spikes is bent while coupled to one of the mold parts, and a molten plastic is injected about at least a bent portion of the bent first wire. The wire can be bent before the mold closes but after attachment to the mold, while the mold is closing, and/or after the mold is closed. The wire can be bent in any suitable manner, preferably having first and second bends of at least 60°, and a bump of at least 1 mm between the first and second bends. A robot arm can be used to concurrently secure multiple straight wires from a wire holder platform, and positioned them onto the mold part.
