Manufacturing
From raw material to packaged product, fully controlled in-house.
Production Process
From material handling to final QC, every step follows strict standards.
High-polymer materials and metal parts are strictly screened before entering the warehouse.
Precision die-casting forms a dense, strong body that outperforms ordinary processes.
Dozens of machines finish the shackle, cylinder and keys with high precision.
Polishing and plating give the body excellent rust resistance and a refined look.
Manual and fixture-based assembly ensures smooth operation and reliable mechanism.
Every lock passes 100% opening, rust-resistance and strength tests.
