The safety of a tool starts on the factory floor. Cleanroom standards are no longer exclusive to skincare; they are now standard for high-end tool manufacturing.
Standard Operating Procedures (SOPs):
Dust-Free Workshops: Assembly and packaging are performed in Class 100,000 cleanrooms to prevent dust particles from being trapped in bristles or coatings.
Worker PPE: Staff must wear hairnets, 手套, and anti-static jumpsuits. This prevents human oils and skin cells from contaminating the tools during the final assembly phase.
Batch Traceability: Each production run is assigned a lot number. If a defect is found, the factory can trace the raw material batch and the specific workers on the line, ensuring total accountability.
