The moving jaw is one of the most important components of a jaw crusher, and it is also a relatively complex part. A reasonable moving jaw structure is a sufficient condition to ensure that the crusher has excellent performance. Its strength and rigidity directly affect the performance of the equipment. Therefore, it is necessary to select a high-quality moving jaw.

　　Great Wall Cast Steel uses standard wooden molds, and the core surface is coated with a special layer to prevent cracking, ensuring a smooth and flat casting surface. Wear-resistant moving jaws use high-quality scrap steel raw materials and auxiliary materials, with strict composition testing before production. Zhengda Heavy Industry Cast Steel castings employ a special heat treatment process to increase service life and resistance to deformation.

　　Great Wall Cast Steel is equipped with advanced and comprehensive testing equipment, including: a German-imported direct-reading spectrometer, ultrasonic flaw detector, magnetic particle flaw detector, hardness tester, universal tensile and impact testing machine, and metallographic analyzer. This allows for UT and MT non-destructive testing, as well as testing of chemical composition, metallographic structure, and mechanical properties. This ensures the quality of the machined jaw crushers produced.
