Recently, the world's leading tire manufacturer Bridgestone announced that its amazing passing through the official brand of the two star products to achieve localization, and upgraded to FS400â…¡ and FD600â…¡ for the Chinese market demand for the majority of Chinese truck and bus users with a more economical and practical solution Program. The two truck/bus tyres FS400II and FD600II that were made locally were upgraded on the basis of Feng Chitong FS400 and FD600. As designed for high-speed, long-distance container and tanker vehicles such as research and development of tubeless truck tires, FS400â…¡ and FD600â…¡ inherited the good handling and excellent driving force, while the original product, are used with excellent wear resistance tread rubber properties, and effective in lifting the tire uneven wear resistance performance. Among them, the FS400II effectively improves the uneven wear of the tire during use by optimizing the curvature of the tread and the shape of the uneven wear groove on the shoulder portion. FD600II adopts the connection rib structure design between the shoulder blocks to significantly improve the tire's resistance to high and low wear. It is reported that the upgraded FS400II and FD600II were mass-produced in Bridgestone's two plants in Shenyang and Huizhou in March 2011. At present, Bridgestone has more than 200 franchised truck tire special sales stores nationwide.
Thermoforming is a manufacturing process used to shape plastic sheets into various custom design products. It involves heating a plastic sheet until it becomes pliable, then using a mold or a vacuum to form it into the desired custom shape.
Thermoforming and vacuum forming are both processes used to shape plastic sheets into specific forms. However, there are some differences between the two techniques:
Thermoforming is a versatile process that is widely used in industries such as packaging, automotive, aerospace, and medical. It offers advantages such as cost-effectiveness, quick turnaround times, and the ability to produce complex shapes with high precision.

1. Process: In thermoforming, a plastic sheet is heated until it becomes pliable, and then it is pressed against a mold using pressure or a vacuum. Vacuum forming, on the other hand, relies solely on the use of a vacuum to draw the heated plastic sheet onto the mold.
2. Mold complexity: Thermoforming is typically used for more complex shapes and intricate molds, as it allows for greater detail and precision. Vacuum forming, on the other hand, is better suited for simpler shapes and molds that do not require as much detail.
3. Material thickness: Thermoforming is often used for thicker plastic sheets, typically ranging from 0.030 to 0.250 inches in thickness. Vacuum forming is more commonly used for thinner plastic sheets, typically ranging from 0.005 to 0.060 inches in thickness.
4. Production volume: Thermoforming is generally more suitable for high-volume production due to its faster cycle times and ability to handle larger sheets of plastic. Vacuum forming is better suited for low to medium volume production, as it has slower cycle times and is limited by the size of the vacuum forming machine.
5. Cost: Thermoforming typically requires more expensive equipment and molds, making it a more costly process compared to vacuum forming. Vacuum forming, on the other hand, is a more cost-effective option for smaller production runs or prototypes.
Overall, thermoforming is a more advanced and versatile process that offers greater precision and complexity, while vacuum forming is a simpler and more cost-effective option for less complex shapes and smaller production volumes.
