The difference between imported synchronous belt and domestic synchronous belt mainly lies in the material, manufacturing process, accuracy, life and scope of application.

First of all, the material is one of the important factors that determine the quality of the synchronous belt. Imported synchronous belts are usually made of high-quality polyurethane materials, which have the characteristics of high elasticity, wear resistance, and tensile resistance, thus ensuring that the synchronous belt has a long life and high precision. The material quality of the domestic synchronous belt is relatively poor, often made of low-cost polyester or rubber material, which is easy to age and wear fast, resulting in short life of the synchronous belt, precision instability and other problems.

Secondly, the manufacturing process is also one of the key factors affecting the quality of the synchronous belt. Imported synchronous belts are usually manufactured with advanced production equipment and precision processing technology, thus ensuring that the synchronous belt has high accuracy and stability. The manufacturing process of the domestic synchronous belt is relatively backward, and the level of equipment and technology is low, which leads to poor accuracy and stability of the synchronous belt.

Third, the accuracy and life of the synchronization belt are directly related to its application in the machine equipment. The accuracy of the imported synchronous belt can usually reach the micron level, and can withstand harsh working environments such as high speed and heavy load, thus ensuring its stable operation on high-precision machinery and equipment. The accuracy of the domestic synchronous belt is usually at the millimeter level, and it can not withstand the harsh working environment such as high speed and heavy load, which is easy to lead to machine equipment failure or damage.

Finally, the scope of application is also one of the important factors affecting the quality of the synchronous belt. Imported synchronous belts are usually used in high-precision machines and equipment, and can adapt to harsh working environments, such as high speed and heavy load. The domestic synchronous belt is usually used in low and medium precision machinery and equipment, which can not adapt to the harsh working environment such as high speed and heavy load, which can easily lead to machine and equipment failure or damage.

To sum up, there are big differences between imported synchronous belts and domestic synchronous belts in materials, manufacturing processes, accuracy, life and scope of application. Therefore, when selecting the synchronization belt, the appropriate imported or domestic synchronization belt should be selected according to the use environment and requirements of the machine and equipment. In addition, manufacturers should focus on improving product quality and brand influence, and constantly improve product performance and quality to meet market demand.
