PV-316L Compression
For lotion, shampoo, sanitizer and household pump valves requiring passivated stainless contact parts.
Where it fits
For Philippine personal care OEMs, brand owners and packaging suppliers, the main risk is not only spring fatigue. Formula contact, humidity, blocked pump heads and import timing all affect launch schedules. AUKIN supports pump valve spring projects with passivated 316L materials, batch inspection and Thailand supply logic for RCEP / ATIGA planning.
