Chocolate blocks in the construction machinery industry - Deepening of Product technology

Breakthroughs in Materials Science

High-chromium cast iron (Cr26%) and tungsten carbide composite materials are used, and a gradient wear-resistant layer is formed through laser cladding technology. The hardness can reach 65-68HRC, which is 40% more wear-resistant than traditional manganese steel

The newly developed nanocrystalline ceramic coating technology (such as the Al₂O₃-TiO₂ system) in 2025 has increased the impact strength to 1200MPa, making it suitable for extremely cold mining environments

Intelligent manufacturing process

Introduce digital twin technology to optimize mold design and control the processing accuracy of complex curved surfaces within ±0.05mm

Enterprises such as Shandong Lingong have adopted 3D printed conformal cooling channels, reducing the heat treatment cycle from 72 hours to 24 hours
