A ring groove texture tungsten alloy dart barrel features axial ring grooves or spiral ring cuts, providing sweat guidance and finger joint positioning. Tungsten alloy hardness ensures groove edges sharp lifelong, binder phase groove bottom protection blocking wear. In grip, ring grooves fit finger joints, pressure embeds grooves, dry-hand edges lock forming directional anti-slip, wet-hand groove bottom drainage preventing slip. During throw, ring design guides rotation, release groove edge resistance cue, flight spin uniform suitable rotational style. Processing mechanical rolling or laser etching forming width-gradient ring grooves, electrochemical polishing groove walls smooth, chemical vapor oxide film covering enhancing self-cleaning. In application, ring groove barrels suit wet-hand players and humid events, front deep grooves sweat-lock, mid shallow breathable, rear no-groove unload. Internal drainage cavities ring groove zone density balanced reinforcing comfort. Compared to coating, ring groove guidance stronger suitable sweat management; compared to knurling, dynamic drainage superior. Environmental etching waste neutralization cycle, groove scraps minimal. Personalization finger length scanning adjusting slot spacing, ensuring grip like ring keys. This ring groove texture defines guidance comfort hub, advancing sweat engineering optimization.
