      About us

      The only way to strict quality control of Kunda crane
      (1) Select the control object; Find out the testing process of the key stressed parts of the product
      (2) Select the quality characteristic value to be monitored; Appearance, size, performance, stress point
      (3) Determine specifications and standards, and specify quality characteristics;
      (4) Select the monitoring instrument that can accurately measure the characteristic value or the corresponding process parameters, or the third-party safety testing means;
      (5) Carry out the actual test and record the data; Basic tensile test, high temperature test, static load test, etc
      (6) Analyze the reason of the difference between the actual and the specification; Find the right problem and keep improving
      (7) Take corresponding corrective measures. When the corresponding corrective measures are taken, the process should still be monitored to keep the process at a new control level. Once a new influence factor appears, it needs to analyze the measured data and correct the causes. Therefore, these seven steps form a closed process, which is called "feedback loop". Let any one of the traceability indicators of safety products have a basis!
      There are two key points in the above seven steps
      (1) Design of quality control system;
      (2) Selection of quality control technology.
