Description

Ball Diameter & Fit:Standard diameters range from 8 mm to 15 mm. Selecting the correct size ensures a snug snap‑fit into the bottle neck finish, preventing leakage during shipping and use.
Surface Finish:A mirror‑like surface (Ra ≤ 0.02 µm) minimizes friction and delivers a luxurious glide across skin, essential for serums, deodorants, and perfumes.
Optimal clearances (0.05–0.08 mm) are derived from Navier–Stokes simulations, balancing capillary hold‑back against gravity‑driven flow.
Transient Flow Analysis:

Transient CFD captures how viscous serums (1,000–5,000 cP) accelerate into the neck channel, preventing air entrapment and ensuring a drip‑free start.
