For high-impact wear components (like jaw plates, mantles, and bowl liners), we primarily utilize high-manganese steel alloys such as Mn13Cr2, Mn18Cr2, and Mn22Cr2, occasionally micro-alloyed with vanadium or titanium to enhance toughness. For heavy structural components (like mainframes, pitmans, and press arches), we utilize high-strength carbon and low-alloy cast steels (e.g., ZG270-500, ZG310-570, or ASTM A148 Gr 90-60) to provide optimal structural integrity and crack resistance under constant cyclical loads.
We employ a multi-layered quality control framework. During design, casting simulation software (MAGMAsoft) optimizes risers and gates to prevent shrinkage. During manufacturing, electric arc furnace melting is paired with ladle refining (LF) and vacuum degassing (VD) to lower oxygen and hydrogen levels. Post-casting, the product undergoes rigorous heat treatment, followed by Ultrasonic Testing (UT), Magnetic Particle Testing (MT), and liquid penetrant checks. All dimensions are verified using 3D laser scanners before machining.
Yes. We specialize in retrofit casting engineering. Our technical team works directly from client blueprints or performs reverse engineering scanning on-site. We can modify bearing positions, mounting footprints, and motor drive locations, allowing you to install higher capacity components without modifying your existing concrete structural foundations.
For standard crusher wear castings and catalog components, our turnaround is 30–45 days. For complex, custom-engineered castings weighing over 20 tons (such as press arches or heavy hollow shafts), manufacturing requires 60–90 days to accommodate precise solidification and detailed stress-relieving cycles. Logistics are managed directly via Qingdao or Tianjin ports using customized heavy-load sea freight arrangements.
