Premium Quality of Large-Scale Complete Mining Equipment: Backed by Top-Tier Structural Component Manufacturing Strength

As China manufacturer of underground mining equipment, Showconn has always adhered to the core principle that "superior complete equipment quality originates from high technology and high-standard structural components." Behind our reliable and durable large-scale mining vehicles and machinery lies a sophisticated structural component manufacturing system—equipped with world-class production equipment, rigorous process control, and comprehensive quality assurance. This solid foundation enables our complete mining equipment to excel in harsh underground environments, delivering unparalleled performance and stability for global mining operations.

Top-Tier Manufacturing Infrastructure: The Core Support for Complete Equipment Reliability

The structural components that form the "skeleton" of our complete mining equipment are produced in a state-of-the-art manufacturing base covering 100,000 square meters, with a total investment of $100 million and a professional team of over 300 technicians. The integrated production chain—from molten steel smelting to precision molding, heat treatment, and post-processing—ensures every structural component meets the strict quality requirements of complete equipment operation.

At the heart of the production system is a smelting department with an annual molten steel capacity of 100,000 tons. Equipped with high-performance equipment including 2 sets of 15t electric arc furnaces, 1 set of 15t LF refining furnace, 1 set of 15t VD vacuum furnace, as well as 2 sets of 10t electric arc furnaces and matching refining facilities, the department adopts the advanced "electric arc furnace + LF refining furnace + VD vacuum furnace" process. Argon blowing during refining accelerates deoxidation and desulfurization, effectively removes inclusions such as Al₂O₃, and achieves precise control of chemical composition. This ensures the molten steel for structural components has ultra-low sulfur and oxygen content, laying the foundation for the high strength and durability of our complete mining equipment.

For molding, three specialized production lines are tailored to the diverse needs of different complete equipment structural components:

· The modified water glass sand automatic molding line (axle housing line) adopts self-hardening sand technology, with a sandbox size of 2300mm×1500mm×1200mm and a production capacity of 6 moldings per hour, achieving an annual output of 30,000 tons. It minimizes gas defects and crack tendencies, making it ideal for thin-walled structural parts such as vehicle axle housings.

· The Pep-set resin sand automatic molding line (bucket tooth line) features a boxless design with a base plate size of 1500mm×1200mm, capable of 30-40 moldings per hour and an annual output of 20,000 tons. Equipped with double-station shell core machines and hot sand regeneration systems, it ensures stable dimensional accuracy for wear-resistant components such as excavator bucket teeth and crusher liners.

· The floor molding line, equipped with 30-ton mobile sand mixers, supports the production of large structural components weighing up to 25 tons (with sizes up to 2100mm×1300mm×1000mm). This flexibility enables us to manufacture key structural parts for large-scale mining machinery, such as crusher main frames and heavy-duty vehicle chassis.

Rigorous Process Control & Quality Assurance: Safeguarding Complete Equipment Performance

To ensure structural components can withstand the extreme conditions of underground mining—high pressure, heavy load, corrosion, and frequent impact—we implement strict process control throughout production. The heat treatment department is equipped with electric heating chamber-type normalizing furnaces, continuous through-quenching furnaces, car-type tempering furnaces, and other advanced equipment. Processes such as normalizing + tempering and low-temperature tempering significantly enhance the mechanical properties, wear resistance, and fatigue resistance of structural components. This ensures our complete mining equipment, from underground transport vehicles to crushing machinery, maintains stable performance even after long-term high-intensity operation.

The post-processing department further polishes the quality of structural components with catenary shot blasting machines, hook shot blasting machines (for initial and fine blasting), and dedicated grinding and cleaning rooms. Every structural component undergoes rigorous surface treatment to remove burrs, rust, and impurities, ensuring perfect compatibility and assembly accuracy with other parts of the complete equipment.

Comprehensive quality testing is implemented at every stage. Our test laboratory is equipped with OBLF spectrometers and CET-I intelligent gas evolution testers, conducting full-process inspections from raw material verification and molten steel composition analysis to finished product mechanical property testing. This zero-tolerance quality control system ensures no defective structural components enter the complete equipment assembly process, directly safeguarding the reliability and safety of the final product.

Diversified Complete Equipment Matrix: Empowered by High-Quality Structural Components

Showconn's large-scale complete mining equipment covers a wide range of applications, all relying on high-quality structural components to deliver exceptional performance:

· Underground mining equipment vehicles: Cast steel axle housings, thrust rod supports, and heavy-duty track plates—produced with high-purity molten steel and precise molding—ensure the vehicles’ load-bearing capacity and passability in narrow, rugged underground tunnels.

· Mining crushing machinery: Movable jaw plates, static jaw plates, crusher liners, and sand making machine hammer heads—manufactured with wear-resistant steel and advanced heat treatment—exhibit outstanding wear resistance, extending the service life of the complete equipment.

· Customized large-scale mining machinery: Structural components weighing from a few kilograms to 25 tons, compatible with various materials such as wear-resistant steel, alloy steel, and stainless steel, meet the personalized needs of different mining scenarios.

Core Competitiveness: Quality-Driven Complete Equipment Advantages

The strong structural component manufacturing strength endows our complete mining equipment with three core competitive advantages:

1. Unmatched Durability: High-purity molten steel, rigorous heat treatment, and precision molding make structural components resistant to wear, impact, and corrosion, significantly extending the service life of complete equipment and reducing maintenance costs for customers.

2. Superior Stability: Strict quality control ensures consistent performance of structural components, enabling complete equipment to operate stably in extreme underground environments with low failure rates, improving mining operational efficiency.

3. Flexible Customization: Multiple advanced production lines support the manufacturing of structural components of various sizes and specifications, allowing us to quickly respond to customized needs for complete mining equipment, meeting the unique requirements of different mines.

"For complete mining equipment, structural components are the foundation of quality and reliability," said a spokesperson for our company. "By adhering to high standards in structural component manufacturing—from smelting to molding, heat treatment to testing—we ensure every piece of complete equipment delivered to customers is a reliable partner for safe and efficient mining operations."
