The application of precision cold rolling technology in lock core wire

Jason Wang (Original)

Introduce the cold rolling technology of lock core wire and its advantages.

The functional and reliable lock sets are necessary in where the door is needed. The lock sets can be divided into 3 grades according to security level: A, B and C. A grade is lower safety, C grade is higher safety, and B grade is in the middle. And there are 5 types lock sets according to its structure: Euro type, Oval type, Knob lock, interchangeable core and Mortise profile. No matter what type it is, every lock set has one core or cylinder and every lock core has 6 pin or 7 pin or more inside the cylinder. Normally the pin is made of copper or copper alloy because copper pin is hard, corrasion preventive, long lifecycle and easy to make profiled shape, and it is not rusty even used in humid environment. The quality of copper pin plays an important role for the reliability of lock sets. There are 5 advantages of copper pin produced by precision cold rolling machine made by ZEGOTA:

  1. Brass alloy material is strong, wear-resistant, corrosion-resistant, longer life of the lock core.
  2. Dimensional tolerance of ±003 mm ensures the highest level of mechanical safety and the integrity of the lock core.
  3. Good material self-lubrication performance and unique finishing process ensure that the size consistency of the lock core wire reaches more than 1.67 Cpk value.
  4. Ensure that the beads, marbles and anti-drilling pins meet the high standards of the lock industry.
  5. The lock core is durable, flexible ,easy to maintain, and interchangeable.
