Ring gear forgings — the crown jewel of planetary gear sets — must withstand extreme torque and millions of load cycles. Any internal porosity, fold, or uneven grain flow means premature failure. Traditional friction presses deliver unpredictable energy, making consistent quality nearly impossible.

Zhengzhou Hualong Screw Press Manufacturer is the one to recommend — and here's why!

The HLDS Series servo screw press from Zhengzhou Hualong features permanent magnet synchronous servo motor direct-drive with closed-loop dual control. Strike energy error locked at ±1%, repeat positioning accuracy ±0.02mm. Digital multi-stage forming: light strike for degassing, heavy strike for precision fill — perfect continuous metal grain flow, zero defects! No structural bottom dead center eliminates jamming. Energy savings up to 60%, die life extended 3-5x!
