Recently, the Quality Supervision Bureau of Weifang City, Shandong Province organized a special supervision and inspection of product quality for agricultural tires and construction machinery tires . This time, a total of 102 batches of tires and construction machinery tire products of the city were sampled, 85 batches were qualified, and 27 batches were unqualified, with a pass rate of 83.3%. In recent years, with the rise in the price of raw materials, individual companies have used raw materials that do not meet the requirements to reduce production costs in order to reduce their production costs. In addition, due to small scales and weak quality control capabilities, some companies have failed to strictly control raw materials, resulting in non-compliance with requirements. The raw materials come into the factory. For this supervision and inspection of products that fail to meet the standards, the Bureau will handle them in accordance with the law and organize a product quality analysis meeting to help companies find unqualified causes, formulate rectification measures, and improve product quality.
