Different printed matter has certain requirements for the performance of the scraper, such as printing material resistance, acid resistance, alkali resistance, oil resistance, wear resistance, certain hardness, strength, resilience, straight cutting edge, certain length, thickness and other performance indicators. The performance indicators of the squeegee will be directly reflected in the stability and effect of the screen printing. In order to print clear dots and patterns, it is required that the pressure on the embossing line on the entire squeegee edge is equal. The elasticity and hardness of the scraper are to make the embossing line thin and solid, and the pressure at each point is uniform, not only hope to have a straight and sharp cutting edge, but also hope that the scraper has a certain elasticity and hardness.
