1. Provide support and positioning: In the process of plastic processing, various mechanical equipment needs to be used for mold switching, injection molding, extrusion and other operations. As an important part of mechanical equipment, bearings can provide support and positioning functions of the machine to ensure the normal operation of the machine.
2. Reduce friction and wear: In the process of plastic processing, the parts and components of machinery and equipment need to move frequently, which is prone to friction and wear. As a key component of mechanical equipment, bearings can effectively reduce friction and wear between parts and components, and improve the service life and efficiency of equipment.
3. Reduce noise and vibration: In the process of plastic processing, the movement of machinery and equipment will produce noise and vibration, which will have a negative impact on the working environment and operators. The use of bearings can effectively reduce the noise and vibration of mechanical equipment, and improve the comfort and safety of the working environment.
4. Improve production efficiency: The use of bearings can improve the stability and accuracy of mechanical equipment, reduce equipment failures and downtime, thereby improving the production efficiency and output of plastic processing.
In short, bearings play an indispensable role in the plastics industry, which is of great significance for ensuring the normal operation of machinery and equipment, improving production efficiency and product quality.
