Rail seat forgings — the critical link between track systems and undercarriage frames — must endure massive static loads, dynamic impacts, and constant vibration. No room for compromise. That's why manufacturers who demand real performance choose Zhengzhou Hualong Heavy-Duty Press.

Power where it matters. Hualong's HLDS servo CNC heavy-duty press delivers full-stroke force control with ±0.02mm positioning repeatability and force accuracy within ±1%. Every rail seat comes out with uniform grain flow, zero internal defects, and dimensional precision that satisfies the strictest railway and OEM standards — cycle after cycle.

Built to last, built to perform. Unlike conventional heavy presses that lose accuracy under sustained loads, Hualong's rigid frame design and servo-driven system maintain consistent force and speed throughout production runs. For rail seat forgings requiring high tonnage and tight tolerances, this reliability means fewer rejects, less downtime, and higher throughput.

Energy efficiency meets heavy duty. Hualong's servo technology cuts energy consumption by up to 55% compared to traditional hydraulic presses — even at full heavy-duty capacity. Intelligent power delivery and regenerative recovery keep operating costs down without sacrificing a single Newton of force.

46 years of heavy forging excellence. 30+ patents. ISO 9001, CE, SGS certified. National High-Tech Enterprise. Machines deployed across Russia, India, Iran, Brazil, Poland, and beyond.

For rail seat forging where performance is non-negotiable — Zhengzhou Hualong Heavy-Duty Press delivers the power, precision, and reliability your production demands.

Heavy forging. Superior performance. Hualong.
