The lock industry is developing abroad earlier than the domestic level, and the level is high. From the perspective of the international lock market, China's locks occupy most of the low-end market, and the high-end lock market is basically occupied by foreign advanced lock products. . At present, there are about 300 enterprises in the lock industry in China, and the eastern coastal areas are relatively concentrated. The industrial clusters of locks are mainly in Guangdong, Zhejiang, Shanghai and Shandong. The above four provinces account for more than 90% of the output value of China's lock industry.
This time, we randomly selected 90 batches of products from 90 enterprises in Zhejiang, Shandong and Guangdong provinces. 81 batches of 81 companies were qualified, and 9 batches of 9 companies were unqualified. The rate and product pass rate are both 90.0%. This time, there were 52 enterprises in Guangdong Province, and 4 enterprises were unqualified. The regional qualification rate was 92.3%, which was higher than the national average. In Zhejiang Province, 37 enterprises were randomly selected, and 5 enterprises were unqualified. The regional qualification rate was only 86.5%. It is 3.5 percentage points lower than last year.
Guangdong Province and Zhejiang Province, as the concentration of national lock enterprises, the development model of the two is not the same. From the scale of enterprises, the scale of Guangdong Province is larger than that of Zhejiang Province, and Wenzhou City of Zhejiang Province is mainly small enterprises. Some enterprises are also family-type workshops. There is no standard factory. They only rent a little place for production, and the management is not in place. The quality awareness is weak, resulting in low product quality and the product qualification rate is lower than the national average. The enterprises with better supervision and spot checks have basically established a sound and effective quality management system, scientific management; strong technical force, independent product research and development capabilities; complete production and inspection equipment, strict inspection; high quality of staff, Can be produced in strict accordance with the standard.
The test results of all the test items of this spot check are counted. The unqualified items appearing in the spot check include: the interlocking rate of the marble mortise lock, the axial static load of the marble mortise lock, the mortise lock The length of the tongue extension, the mutual opening ratio of the ball door lock, the mutual opening rate of the bicycle lock and the mutual opening rate of the external door lock are all mandatory items specified in the standard.
