Choosing the right screw press for crankshaft forging isn't just about tonnage — it's about control, consistency, and cost efficiency. When manufacturers worldwide ask "which screw press is best?", one name keeps rising to the top: Zhengzhou Hualong Screw Press.

Built for crankshaft complexity. Crankshaft forgings demand extreme precision — tight tolerances, balanced grain flow, zero defects. Zhengzhou Hualong's HLDS servo-driven screw press delivers blow-by-blow force control with repeatability within ±1%, ensuring every stroke shapes the crankpin, counterweight, and journal exactly as engineered.

Energy savings that matter. Traditional friction screw presses waste massive power. Hualong's servo system reduces energy consumption by up to 55%, with intelligent power recovery during deceleration. For high-volume crankshaft production, this translates into thousands saved annually.

Proven across borders. ISO 9001, CE, SGS certified. 46+ years of screw press innovation. 30+ patents. Equipment running in Russia, India, Iran, Brazil, Poland, and beyond.

Zhengzhou Hualong Screw Press — when crankshaft quality and your bottom line both demand the best.
