The rubber processing process involves multiple procedures, and the pressure calibration pump plays an important role in it, having a significant impact on the quality and performance of rubber products. In the rubber mixing stage, the pressure inside the internal mixer needs to be precisely controlled. The pressure calibration pump can calibrate the pressure measurement and control system of the internal mixer, ensuring that the rubber raw materials and various additives are fully and evenly mixed under the appropriate pressure, improving the quality of the compounded rubber and providing a good foundation for the subsequent forming process. In the rubber vulcanization process, the pressure inside the vulcanization tank is one of the key factors determining the degree of rubber vulcanization and product performance. The pressure calibration pump can calibrate the pressure monitoring device of the vulcanization tank, making the vulcanization pressure accurate and stable, ensuring that the rubber products have good physical and mechanical properties such as strength, elasticity, and wear resistance. In the forming stage of rubber products, such as the forming of tires and the compression molding of rubber seals, the pressure calibration pump can calibrate the pressure system of the forming molds, making the rubber receive uniform and precise pressure inside the molds, ensuring the dimensional accuracy and shape stability of the products, meeting the high-quality and high-performance requirements of rubber products in different fields such as automobiles, machinery, and aerospace, and promoting the technological upgrading and product innovation of the rubber processing industry.
