Hollow forgings — rings, sleeves, hubs, and tubular components — are everywhere. Bearings, valves, gear blanks, flanges. Their value lies in one thing: uniform wall thickness, defect-free interiors, and continuous grain flow around the entire circumference. Get any of those wrong, and the part fails in service.

That's why forging hollow shapes demands more than brute force. It demands intelligence.

Zhengzhou Haloong's servo screw press delivers exactly that.

Unlike conventional hydraulic or friction screw presses, Haloong's fully synchronous servo system gives you independent, programmable control over force, speed, stroke, and position — in real time. For hollow forgings, this translates into three decisive advantages:

One — Superior metal flow. The servo motor applies force precisely where and when it's needed, guiding material evenly around the die cavity. No uneven filling, no folding, no internal laps — even for deep-draw hollow geometries.

Two — Consistent wall thickness. Position accuracy within ±0.1mm ensures every forged ring or sleeve meets tolerance without secondary machining. Scrap rates drop dramatically.

Three — Real energy savings. Servo-only-when-working operation cuts power consumption by 45–60% versus traditional friction screw presses. Less heat means less die wear and longer tool life.

Haloong has been China's screw pressespioneer since 2009, with 3,000+ machines deployed across 30+ countries. Their engineering team specializes in hollow forging process optimization — die design, stroke sequencing, and production integration.

Hollow parts demand a press that thinks. Zhengzhou Haloong doesn't just press — it performs.
