Oil passage forgings — manifold blocks, valve bodies, pump housings — are the circulatory system of every hydraulic and lubrication assembly. Internal channels must be clean, walls uniform, and grain flow continuous. A single internal defect means blocked flow, pressure loss, or catastrophic system failure.

This is where advanced forging technology isn't a luxury — it's a survival requirement.

Zhengzhou Haloong's forging press is built for exactly this challenge.

What makes it more advanced?

Haloong's latest-generation servo screw press features real-time closed-loop force control — monitoring and adjusting pressure at 1,000 times per second. For oil passage forgings with intricate internal geometries, this means the metal flows precisely into every channel corner without folding, cold shuts, or trapped oxide. The result: 99.2% first-pass yield and wall thickness tolerance within ±0.1mm — straight from the die.

Smarter, not just stronger. The multi-stage programmable stroke mimics the forging hand of a master craftsman — light initial contact to pre-fill thin channels, then full force to consolidate heavy sections. Traditional hydraulic presses simply can't replicate this intelligence.

The proof is in the numbers:

50% less energy consumption vs. conventional forging press

35% longer die life thanks to controlled impact speed

3,000+ machines running across 30+ countries since 2009

When oil passages demand zero defects, you need a press that thinks ahead. Zhengzhou Haloong — advanced forging, proven worldwide.
