A bomb-shaped tungsten alloy dart barrel features mid-section bulge with tapering ends curve, center of gravity centered at thumb-web palm root junction, providing mid-weighted support and dynamic unloading. Tungsten alloy density concentrates mass at bulge, binder phase gradient ensuring curve transition strength. In grip, mid-bulge fits thumb-web, fingertips at high points, wrist tension dispersed, full palm grip natural. During throw, bomb streamline optimizes aerodynamics, release self-spin stable, flight posture self-stabilizing, board entry tail inertia buffering. Processing isostatic pressing mold presetting curvature, sintering segmented cooling avoiding stress, five-axis linkage sculpting contour, surface electrochemical wave grooves, coating chemical vapor titanium nitride film. In application, bomb-shaped suits mid-level balanced power and mixed-distance switching, internal energy-storage cavities mid-density buffering impact. Compared to straight, bomb palm root support stronger, suitable for close explosive; compared to torpedo, drag slightly higher but inclusive. Environmental curve processing efficiency high, waste complete. Personalization curve scanning adjusting bulge arc, matching palm shape. This bomb-shaped serves as mid-firm structure, connecting linear and tapered performance.
