Step 1 Blast Furnace Ironmaking
We put iron ore, coke and flux into the high-temperature blast furnace for high-temperature smelting to produce qualified molten iron, the original raw material of our self-produced steel.
Step 2 Converter Steelmaking
Molten iron is refined in the converter, with chemical composition strictly adjusted to produce special steel liquid with high hardness and corrosion resistance specially for padlock production.
Step 3 Continuous Casting
The qualified steel liquid is continuously cast into solid steel billets to ensure uniform internal texture and stable material performance.
Step 4 Hot Rolling & Profiling
Steel billets are heated and rolled into customized steel strips and steel bars of different specifications, exclusively for padlock bodies and shackles.
Step 5 Stamping & Forming
We cut the self-made steel materials, then use precision molds to stamp out lock bodies, shackles and other structural parts, and remove burrs for precise size control.
Step 6 Surface Treatment
Carry out polishing, sandblasting and imitation copper electroplating treatment on lock parts to achieve beautiful appearance and strong rust resistance.
Step 7 Assembly & Commissioning
Install lock cylinders, pins, springs and other accessories into the lock body, match keys one by one, and test the opening and closing flexibility repeatedly.
Step 8 Strict Quality Inspection & Packaging
Each finished padlock will pass anti-prying, tension and appearance inspections. Qualified products will be packed and stored for global export delivery.
