COC Medical Part Cleanliness Exceeding Standard
Problem Phenomenon
COC medical devices fail the particle inspection; fibers and particles are still detected in products produced in clean rooms, and traceability involves multiple links.
Cause Analysis
Raw material unpacking, grinding and recycling, mold oil stains and packaging links can all introduce particles; COC static electricity easily absorbs environmental fibers; insufficient post-treatment cleaning leaves residual particles.
Solution
①Clean management of the whole process, with closed conveying of raw materials; ②prohibit fiber-shedding wiping materials for mold cleaning; ③ultrasonically clean the products and package them cleanly; ④establish factory standards for particle inspection.
Key Takeaway
COC medical part cleanliness is a whole-chain project; the static adsorption characteristic requires stricter environmental control; ultrasonic cleaning is the key post-treatment to meet the standard.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
