Advanced OEM metallurgical casting products engineered for high impact and wear-resistant applications.
Modern mineral extraction and aggregate production systems rely on mechanical stress configurations that demand peak wear resistance and dimensional stability. Cone crushers occupy a critical stage in the comminution process, taking coarse primary crusher feeds and reducing them to fine, well-graded outputs under continuous high-tonnage cycles. At this level of force, standard alloy formulations fail prematurely due to high mechanical fatigue and abrasive wear.
As a leading Chinese foundry specializing in heavy-duty castings, Henan Hanhai Metallurgy Mining International Trade Co., LTD engineers specialized replacement bodies and custom structural components. Achieving peak crushing efficiency requires a holistic understanding of crushing cavity geometry, wear dynamics, and metal chemistry to guarantee structural integrity.
Combining technological innovation, vertical supply chain integration, and deep metallurgy expertise.
We use simulated filling software to predict heat profiles, avoiding internal defects like voids and micro-cracks before casting begins.
Select tailored alloys, including high-manganese steel (Mn13Cr2, Mn18Cr2, Mn22Cr2) and heat-treated alloy steel, for structural components.
Our machine shop handles heavy turning, boring, and milling, providing ready-to-install parts straight to your site.

A cone crusher operates on a simple principle: material is crushed by compressive forces between a moving mantle and a stationary bowl liner. However, the dynamics within the crushing chamber are complex. The performance of the crusher depends on matching the cavity design with the specific characteristics of the feed material.
Custom manufacturers use 3D laser scanning to track wear profiles on used liners. By analyzing how manganese steel wears in different zones, engineers can adjust the liner thickness. Increasing thickness in high-wear areas and reducing it in lower-load zones maintains the optimal chamber profile longer, improving throughput and reducing power demand.
High-manganese steel (Hadfield steel) is the standard material for cone crusher wear parts due to its work-hardening properties. Under impact and high pressure, the surface structure transforms from austenite to martensite, forming a hard outer layer while the core remains ductile to absorb shocks.
Adding chromium improves yield strength and prevents the liners from plastic deformation under heavy load, ensuring stable operation.
The mainframe of a cone crusher supports the internal forces of the crushing cycle. When crushing hard rock, these forces can cause fatigue cracks in cast components over time. Custom castings address this by optimizing wall thicknesses and transition radii using Finite Element Analysis (FEA).
Upgrading to high-strength alloy steels, combined with stress-relieving heat treatments (normalizing and tempering), ensures the frame can withstand continuous load cycles. Our foundry uses digital gas-fired furnaces to control temperature cycles, minimizing residual stress in large cast components.

For high-abrasion applications like granite and basalt, we recommend high-manganese steel with chromium additions (e.g., Mn18Cr2 or Mn22Cr2). The chromium helps increase yield strength, preventing the mantle and bowl liner from deformation under heavy crushing forces. Under impact, this material work-hardens to protect the contact surfaces while retaining core toughness.
We use a structured quality inspection process, including chemical composition testing via optical emission spectrometers, ultrasonic testing (UT) for internal defect detection, magnetic particle testing (MT) for surface crack inspection, and dimensional verification using coordinate measuring machines. All test results are documented and supplied with the casting shipment.
Lead times depend on the size and complexity of the part. Making new patterns typically takes 15 to 25 days, followed by casting, heat treatment, and final machining, which takes 30 to 45 days. For standard components where patterns are already available, production can be completed in 30 to 40 days.
Yes. Our engineering department can work from original engineering drawings, 3D CAD models, or physical samples. We use laser scanning to reverse-engineer worn components, reconstruct the original dimensions, and add wear allowances to improve the replacement part's service life.
Proper heat treatment is critical to achieving the required mechanical properties. For carbon and alloy steels, normalizing, quenching, and tempering break down coarse casting grains and refine the microstructure. For high-manganese steels, water solution annealing dissolves carbides into the austenitic matrix, providing the necessary ductility and preventing premature failure during operation.
