Plunger forgings are core precision parts for hydraulic pumps, oil cylinders and engineering machinery, requiring ultra-tight dimensional tolerance, stable roundness and integrated metal streamline to avoid oil leakage and premature abrasion during long-term operation. Zhengzhou Hualong CNC servo electric screw press is perfectly tailored for high-standard plunger precision forging, highly recognized by global forging manufacturers.
With over 16 years of foreign trade experience, our forging equipment has been exported to more than 30 countries worldwide. Equipped with an independent CNC numerical control system, the press realizes programmable precise locking of forging energy, striking stroke and ram position, with forging force control accuracy within ±2% and outstanding repeat forming consistency. It strictly controls the cylindricity and radial runout of plunger blanks, greatly minimizing follow-up machining allowance and lowering reject rate caused by dimensional deviation. The integrated rigid frame and long guide structure effectively resist eccentric load, preventing mold damage and extending die service life remarkably.

Prior to delivery, every machine undergoes comprehensive factory inspection to eliminate hidden faults. We provide multilingual operation manuals, 24-hour remote video diagnosis and online debugging to resolve minor failures efficiently. For key overseas markets, we build localized service networks with spare parts inventory and on-site technical support.
Unlike manufacturers only focusing on one-time equipment sales, Hualong electric screw press to long-term stable after-sales accompaniment. We help plunger forging factories maintain steady production efficiency and product precision for years, making us your trustworthy long-term partner for precision forging equipment.
