2. Security

  1. System Testing:
    The accuracy of electronic function and the effect in electronic system when change in environmental conditions happens are ensured and controlled by testing the stability of electronic operation. 
  2. Electronic & Mechanical Combination:
    Thousands of tests are conducted to make sure the accuracy and stability of electronic and mechanical combination, which guarantees their normal functioning. 
  3. Security Testing:
    The level that machines can bear when being destroyed is tested and estimated through the authentic simulation.
  4. Anti-drilling Cylinder:
    There are specific components and design in our cylinder to avoid drilling and destroying.
  5. Some of materials used in our products are stainless steel or hardened steel, whose strength and toughness are better than copper ones. Stainless steel products are endurable against heat, cool or corrosion.
  6. There is REAL's unique automatically fixed-locating mechanism in the cylinder, which allows user to lock more correctly and conveniently. 
  7. Electronic-recording Seal Mechanism:
    Such locks as RL-9152 can be applied when strong security is demanded, because any tamper attempt will be recorded by the electronic tamper-proof seal, shown as time in Days/Hours/Minutes. With this mechanism, seal numbers will be displayed permanently on LED screen so there is clear and obvious sign of any tamper attempt for administrators to trace.

3. Surface Processing

The current Surface Processing for the locks and parts we can offer is : Chrome plated, Nickel plated, Brass plated, Powder coating, heat treatment, laser carving ….etc.  We can pass the standard of RoHS.

In the predictable future, we will devote REAL to develop the integrated techniques of mechanical arts with electronic technology. Our focus on the development of techniques will be oriented to: 

  1. The Security of Technology.
    That is, REAL will keep developing brand new concepts and products by integrating electronic technology with traditional and industrial techniques.
  2. Precise and Art-State Techniques to Manufacture Hardware.

It means we will keep following and controlling the more precise and more dedicate technology of manufacturing by integrating techniques with the upside in the industry chain.
