Leather processing involves multiple complex and delicate procedures, and the pressure calibration pump plays an indispensable role in it. In the leather tanning process, the pressure inside the tanning drum needs to be precisely controlled. The pressure calibration pump can calibrate the pressure monitoring and control system of the drum, allowing the leather to fully absorb the tanning agent under the appropriate pressure and chemical agents, ensuring that the softness, toughness, and durability of the leather reach the desired level. In the leather dyeing process, the pressure calibration pump can calibrate the pressure devices in the dyeing equipment, ensuring that the dye evenly penetrates into the leather fibers under a stable pressure, resulting in a uniform dyeing effect, bright and long-lasting colors. In the later finishing processes of leather, such as embossing and ironing, the pressure calibration pump can calibrate the relevant pressure equipment, precisely controlling the pressure magnitude and distribution, making the leather surface form clear, beautiful, and long-lasting textures and gloss, improving the quality and added value of leather products, meeting the demand for high-quality leather products in different fields such as fashion, automotive interiors, and furniture decoration, and promoting the technological progress and product innovation of the leather processing industry.
