Cause Analysis

Our engineering team found that inconsistent bottle neck tolerances, improper roller ball press-fit force, and insufficient cap torque control were the root causes of the leakage issues.

Solution

As an experienced rollerball bottle factory, Vesseluxe refined neck dimensions, optimized roller ball installation pressure, and introduced 100% leak, rolling, and torque tests before shipment. Every batch of rollerball bottles met strict quality standards.
