Recently, relying on mature manufacturing processes including silica sol lost-wax investment casting and centrifugal casting as well as forging technology, our company has continuously upgraded production capacity for high-pressure hydraulic components and precision steel castings, launching a new generation of high-performance pressure-bearing parts for construction machinery, mining & metallurgy equipment and marine machinery.

Higher requirements on dimensional accuracy, material strength and sealing stability for cylinder parts, valve bodies and pump housings are being raised by manufacturers of construction machinery and large hydraulic equipment. Using materials such as 40Cr, 42CrMo alloy forged steel, high-chromium cast iron, stainless steel and superalloys, our company optimizes the whole process including blank forging, heat treatment and surface hardening for wear resistance, with strict control over metallographic structure and hardness indicators. The finished products can operate steadily under harsh working conditions in long-service high-pressure hydraulic systems.

Besides hydraulic components, we take full advantage of near-net-shape casting technology to integrally fabricate metal components with internal flow channels and complex irregular curved surfaces, greatly reducing machining allowance. We provide one-stop supporting services covering non-destructive testing, precision CNC machining and anti-corrosion surface treatment. Our components are widely adopted in new energy vehicles, aerospace, rail transit and wind power equipment.

With steady recovery in overseas infrastructure and high-end equipment demand, the company keeps expanding overseas markets. We support custom single-piece development and mass standardized production, manufacture products in compliance with national standards and customers’ drawing specifications, and keep supplying stable and reliable precision casting and forging component solutions for equipment manufacturers at home and abroad.
