Machining | Heavy Structural Component Manufacturer
Delivering the reliable "joints," "skeleton," and "connections" essential for heavy equipment. We specialize in manufacturing high-strength, complex structural components for construction machinery and mining equipment, ensuring delivery certainty through end-to-end closed-loop quality control.
Core Process Benchmark
Define reliability with measurable manufacturing standards.
Our Products
From core structures to critical fasteners, we understand the function and operating conditions of every component to guide manufacturing.
Boom, stick, and other large-scale welded structural components
Constructed with high-strength steel, robotically welded, and stress-relieved as a single unit. Precision-machined hinge holes ensure excellent coaxiality, delivering powerful output and smooth operation.
Pins, Connecting Rods, and Hydraulic Cylinders
Combined through hard turning and milling to create a high-hardness surface, significantly enhancing wear resistance and fatigue life.
Gears, Gear Rings, and Slewing Bearings
Capable of machining large-module gears and quenching gear teeth to ensure smooth, reliable, and long-lasting operation of heavy-duty transmission systems.
Bucket, screening bucket, and other structural components
Built with high-strength steel to ensure precise dimensions and geometric tolerances, significantly enhancing wear and impact resistance for reliable, stable performance in construction machinery.
Chassis frames for transfer vehicles
The machine's main frame features an optimized box-section design and welded deformation control processes, forming the foundation of overall rigidity, precision, and long-term stability.
Track pads, track links, and other undercarriage components
Engineered for harsh conditions with exceptional impact resistance and wear durability.
