At the core of a reliable brush head is a bond that must not fail. The connection between each individual bristle and its base is fundamental to product safety, durability, and user trust. To ensure this critical integrity, our quality control includes a rigorous Bristle Pull-Force Test on every production batch.
The Purpose: Preventing Failure Before It Happens
A bristle that detaches during use is more than an inconvenience—it’s a potential safety concern and a direct hit to brand confidence. Our pull-force test simulates years of abrasive brushing stress in a single, controlled moment, proactively identifying any weakness in the planting process. It is a non-negotiable checkpoint in our commitment to a defect rate of under 1%.
Our Test Method & Standard: Data-Driven Assurance
We employ calibrated mechanical testers to apply a precise, controlled pulling force to randomly selected bristles from sampled brush heads.
-
Procedure: A single bristle is securely gripped and pulled axially until separation from the head base occurs.
-
Measurement: The instrument records the exact force (measured in Newtons, N) required to dislodge the bristle.
-
Acceptance Criterion: The minimum pull-force for any tested bristle must significantly exceed international safety benchmarks and our own stringent internal specifications, which are far greater than any force encountered in normal or even aggressive brushing.
This objective, data-driven test provides irrefutable proof of the reliability of our copper-free bristle planting technology.
