　　Product Highlights 
　　1. Reinforced design for enhanced load-bearing capacity: ZGMn13 high-manganese steel, after water‑quenching and tempering heat treatment, combines excellent impact toughness with work‑hardening properties. Its thicker cross‑section offers superior resistance to deformation, effectively preventing premature fracture. 
　　2. Three tooth profiles, tailored to the ore: offering thickened versions of three basic tooth profiles—flat, triangular, and wave—to allow flexible selection based on site conditions, thereby achieving an optimal balance between crushing efficiency and liner life. 
　　3. Upgrade Solution: Doubling Service Life — For highly abrasive ore‑handling conditions, we have significantly thickened the tooth plates to extend their service life. 
　　User pain points 
　　The toggle plate is the most frequently replaced wear part in a jaw crusher. Rapid wear leads to high costs and frequent downtime; variations in ore type and feed size impose vastly different requirements on tooth geometry and material, making it difficult for a universal plate to meet all needs. 
　　Solution 
　　Our company’s ZGMn13 series of thickened tooth plates made from high-manganese steel are specifically designed for jaw crushers. Addressing the challenge of wear, high-manganese steel undergoes rapid surface work-hardening under severe impact; to accommodate varying operating conditions, we offer three upgraded tooth‑profile options with increased thickness; and to ensure seamless compatibility, our products are suitable for a wide range of models from major domestic and international OEMs. 
　　I. Product Description 
　　During operation, the tooth plates endure severe impacts, compression, and friction from the ore. Our company’s ZGMn13 series of thickened high-manganese steel tooth plates can be manufactured to customer specifications in three basic tooth profiles—flat, triangular, and wavy—in a thickened design, making them suitable for models from major OEMs both domestically and internationally.

　　III. Product Features and Advantages 
　　• A comprehensive material system covers a wide range of operating conditions: the wear plates feature a thickened design with high structural rigidity, effectively resisting bending deformation. The base material is available in three options—ZG120Mn13, ZG120Mn13Cr2, and ZG120Mn18Cr2—allowing for flexible selection based on material hardness and crushing conditions. 
　　• Structural upgrades to enhance the continuity of crushing operations: Various structural options are available, including titanium alloy rod inserts, high-chromium alloy block inserts, and spliced tooth plates, ensuring continuous production line operation. 
　　• Precise fit, ready to install upon arrival: The product is precisely matched to jaw crusher models from major domestic and international OEMs, supports customization based on customer-provided drawings, is manufactured strictly according to specifications, and requires no further adjustment or modification during assembly. 
　　IV. Why Choose Us 
　　• Premium Raw Materials: We rigorously select high-quality scrap steel and punched billets that are free of rust and oil, ensuring purity at the source. This guarantees a dense microstructure for the thickened tooth plates and keeps harmful impurities to a minimum, laying the foundation for the impact‑hardening performance of high-manganese steel. 
　　• Ultimate density: Ceramic sand combined with a large-diameter riser casting process effectively eliminates shrinkage porosity and cavities, ensuring a dense and uniform microstructure within the thickened tooth plate, so it can withstand severe impacts from large ore chunks without developing internal defects. 
　　• Precision Melting: Melted in a Fuji electric furnace from Japan and subjected to real-time compositional analysis using a Bruker spectrometer from Germany, with carbon and manganese levels precisely controlled to ensure the thickened tooth plates achieve excellent work‑hardening capability and impact toughness. 
　　• Flawless Casting: A combination of 850°C package baking and bottom-pouring technology significantly reduces sand-hole defects, ensuring the thickened tooth plate’s working surface is smooth and free of casting imperfections, thereby preventing stress concentrations that could lead to premature failure. 
　　• Enhanced metallography: 30-second rapid quenching plus an 800 m³ water‑stirring tank make it easier to obtain a uniform austenitic microstructure, achieving a thickened tooth plate with “hard exterior, tough interior”—the surface is impact‑hardened to HB 500–600 while the core retains high toughness, allowing it to withstand violent impacts from large ore chunks without fracturing. 
　　• Powerful shot blasting: simultaneously removes surface scale and hardens the material, revealing the metal’s natural luster, thereby further enhancing the wear resistance of the thickened tooth plate’s working surface and extending its service life. 
　　• Rigorous quality inspection: Dual-dimensional verification via manual measurement and 3D scanning ensures precise tooth geometry and installation dimensions; magnetic particle and dye penetrant inspections guarantee zero internal defects. 
　　• Transparent delivery: Scan a code to track production progress in real time, with full visibility from material input to shipment, ensuring greater peace of mind for bulk deliveries. 
　　V. Production and Quality Assurance 
　　• Premium Raw Materials: Carefully selected high-quality, rust-free, oil-free scrap steel and punched billets ensure a pure material at the source, laying the foundation for impact work hardening in high-manganese steel. 
　　• Ultimate density: Ceramic sand combined with a large-diameter heating riser eliminates shrinkage porosity and cavities; the tooth plate is densely compacted internally and can withstand violent impacts from large ore chunks without cracking. 
　　• Precision melting: Melted in a Fuji electric furnace from Japan, with real-time compositional verification via spectrometer to precisely control carbon and manganese levels, ensuring work-hardening capability and impact toughness. 
　　• Flawless Casting: Employing a 850°C bake‑out and bottom‑pour process to eliminate sand‑hole defects, ensuring the tooth plate’s working surface and mounting areas are smooth and free of casting imperfections. 
　　• Strengthened metallography: 30-second rapid quenching produces a uniform austenitic microstructure, achieving “hard exterior, tough interior”—the surface is hardened to HB500–600, while the core retains high toughness, preventing fracture under severe impact. 
　　• Powerful shot blasting: removes surface sand and hardens the surface, enhancing the wear resistance of the tooth plate’s working face. 
　　• Rigorous quality inspection: 3D scanning and magnetic particle testing ensure precise tooth profiles and installation dimensions, achieving perfect alignment with the equipment housing. 
　　• Transparent delivery: Scan a code to track progress in real time, with full visibility from material input to shipment.
