Mining & Tunnelling

The Anchor Dome Nut is a high-strength, specialized fastener known for its rounded, domed top and precision-engineered internal threads, designed to mate securely with bolts or screws. Manufactured through a forging process, the nut is shaped under intense pressure and heat, resulting in superior form, exceptional strength, and enhanced durability.

Our Domed Nut is manufactured from high-strength cast iron, providing a durable and reliable fastening solution for grouting bell systems, mining operations, and construction applications. Engineered for maximum stability, it ensures secure component fastening, preventing movement and loosening even under extreme loads and vibrations. With its robust design and precision engineering, this nut delivers outstanding performance in demanding environments.

Our expansion shell anchorage system is designed for strength, precision, and durability. It consists of two high-quality forged shells, a resilient spring component, a precisely engineered tapered nut, and a connecting band — all built to deliver reliable performance under extreme conditions. Ideal for mining operations, this anchorage system is widely used for tunnel reinforcement, rock face stabilization, and securing load-bearing ground. It offers essential support in creating safer and more stable mining infrastructures.

Our drill bits are manufactured using advanced techniques like precision casting, precision forging, and medium-carbon alloy steel machining, ensuring exceptional strength and durability. This combination of processes allows our drill bits to meet the demands of various drilling types and perform reliably in diverse geological conditions. We have many types of customer designed drill bits. Each type of drill bit is designed to optimize performance for specific tasks, ensuring efficiency and precision in various drilling applications.
