Production Line

We are equipped with a full professional production line for wear-resistant castings, specializing in R&D and manufacturing of mining wear spare parts. Our main products include ball mill liners, crusher wear liners, screw flights and other wear-resistant components made of high manganese steel and high chromium cast iron. We implement closed-loop quality control covering smelting, molding & pouring, heat treatment, precision machining, non-destructive testing and finished goods warehousing.

1. Raw Material Smelting Adopting electric arc furnace smelting. We select special wear-resistant materials including Mn13Cr2, Mn18Cr2 high manganese steel and high chromium cast iron. On-line spectroscopic composition monitoring is applied during melting. Samples are retained for each furnace batch to strictly control the proportion of C, Mn, Cr, Si and other elements, ensuring the castings can resist impact and abrasion under severe mining working conditions with heavy abrasion and alternating impact load.
   
2. Resin Sand Precision Molding & Pouring Custom molds are manufactured in accordance with clients’ drawings. Resin sand molding delivers high dimensional accuracy and good surface finish, minimizing casting defects such as blowholes and shrinkage porosity. Flexible production for various sizes is available, with controllable geometric tolerances to guarantee precise fit with ball mills and crushing equipment.
   
3. Heat Treatment (Core Process) Equipped with continuous heat treatment production line, standardized quenching and tempering processes are carried out. We customize hardness & toughness matching scheme per client technical specifications. Parameters of austenitizing, cooling and tempering are adjusted to optimize metallographic structure, balancing impact toughness and surface hardness. It greatly extends service life and reduces equipment downtime for mining operations.
   
4. CNC Precision Machining CNC milling machines, drilling machines and grinders are deployed for finish machining on assembly datum surfaces, bolt holes and positioning surfaces. Drawing tolerances are strictly followed to ensure consistency of assembly dimensions and eliminate on-site fitting problems.
   
5. Full Physical, Chemical & Non-Destructive Inspection for Finished Products Complete pre-shipment inspection: geometric dimension check, Brinell hardness test, metallographic analysis, Magnetic Particle Testing (MT) and Ultrasonic Testing (UT). Material Test Report (MTR) and inspection certificates will be issued for every batch. Products with internal defects or out-of-tolerance dimensions will be segregated and scrapped.
   
   Our production line supports custom manufacturing by drawings or samples. Bulk mining project orders for South America can be delivered steadily. Process records of all procedures are traceable. We consistently supply highly reliable wear-resistant castings and provide long-term spare part solutions for mining customers worldwide.
