One quarter of domestic radial tires failed

Recently, the AQSIQ (General Administration of Quality Supervision, Inspection and Quarantine) released its latest inspection results on the quality of car radial tires across the country. The findings revealed that the pass rate for spot inspections conducted by the company was only 53%, while the sample sampling pass rate stood at 75%. These statistics highlight a clear need for improvement in the overall quality of domestically produced radial tires. Car radial tires are known for their advanced technical design and superior performance compared to bias-ply tires, making them the future direction of the tire industry. The recent inspection focused on two main types: 6.50R16 light truck radial tires and 70/80 series passenger car radial tires. Out of 28 samples tested from 15 different companies, 21 samples from 8 companies met the required standards. However, seven samples failed the test. Among the failures, six samples were found to have issues with the outer edge size. This deviation can lead to serious problems during driving, especially at high speeds, posing potential safety risks to drivers. Industry experts believe that there are three primary reasons behind these non-compliance issues. First, some manufacturers fail to strictly control the quality of imported raw materials. Second, there is often lax oversight during the production process. Third, some companies do not adhere to national mandatory standards, instead producing tires according to foreign specifications, which may not be suitable for the domestic market. These findings emphasize the importance of stricter quality control measures and better compliance with national regulations to ensure the safety and reliability of car radial tires in China.

Automatic Tapping Machine

An Automatic Tapping Machine is a highly efficient and advanced piece of equipment designed to perform tapping operations automatically. It offers precision and speed, significantly reducing manual labor and increasing productivity.
This machine is equipped with advanced technology and features that ensure accurate threading. It can handle a wide range of materials and sizes, making it suitable for various industrial applications.
The Automatic Tapping Machine often works in conjunction with other tools. For instance, a Pillar Drill Machine can be used in combination with an automatic tapping machine. The pillar drill machine is used for drilling holes, and then the automatic tapping machine can be employed to create threads in those holes.
Another related item is the Drill Tap. A drill tap combines the functions of drilling and tapping in a single tool. This can be a convenient option when working with an automatic tapping machine, as it reduces the number of steps and tools required.
The Table Drill Machine is also relevant. It is a compact and versatile Drilling Machine that can be placed on a workbench. In some cases, it can be used in conjunction with an automatic tapping machine for smaller-scale operations.
Finally, the Industrial Pillar Drill is a heavy-duty drilling machine commonly found in industrial settings. It can be used to prepare holes for the automatic tapping machine to create threads.
In conclusion, the Automatic Tapping Machine is a powerful tool for industrial applications. Its combination with other machines like pillar drill machines, drill taps, table drill machines, and industrial pillar drills can enhance productivity and provide efficient threading solutions.
