01
Precision Casting & CNC Milling
We begin with premium-grade zinc alloys and solid brass billets. Using computerized CNC milling, each lever body and rosette is cut with micrometer accuracy, ensuring flawless alignment and weight distribution.
02
Multi-Layered Electroplating
To prevent tarnishing, oxidation, and scratches, every piece undergoes a multi-layer electroplating process followed by a protective lacquer coat, hand-inspected under high-intensity lighting.
03
200,000+ Cycle Durability Test
Internal springs and rotatable latches are stress-tested to endure over 200,000 continuous turns. We ensure smooth operation, zero sagging, and dependable security for years to come.
