A wave-shaped tungsten alloy dart barrel features axial undulating curve, center of gravity tidal between peaks valleys, providing dynamic friction and pressure gradient. Tungsten alloy hardness equilibrates peak-valley strength, binder phase wave gradient buffering vibration. In grip, wave peaks fit finger joints, valleys guide sliding, pressure varies with curve, variable-speed grip adaptive. During throw, wave undulation optimizes airflow separation, release vibration self-eliminating, flight gentle, board entry tail buffering. Processing mold presetting wave arc, sintering wave-segment control cooling, five-axis peak-by-peak sculpting, surface laser wave grooves, coating physical vapor diamond-like carbon film. In application, wave-shaped suits advanced dynamic response and variable events, internal flexible cavities wave density absorbing vibration. Compared to polygon, wave flexibility stronger, suitable for high-frequency; compared to straight, response richer. Environmental innovation high, scraps complete. Personalization wave scanning adjusting undulation, matching finger motion. This wave-shaped represents innovation frontier, advancing intelligent interaction.
