Free Forged Cylinder Block for Heavy-Duty Hydraulic Press Systems. Our free forged cylinder blocks are engineered for use in high-pressure, heavy-duty hydraulic press systems, delivering superior strength, dimensional integrity, and long service life under extreme working conditions. Forged from high-quality carbon or alloy steels, these blocks are designed to withstand high internal pressure and cyclic loading in forging, extrusion, and forming equipment.

Key Features:

  • Material Options: High-strength alloy steels (e.g., 42CrMo) and carbon steels (e.g., 45#) with excellent mechanical performance, pressure resistance, and machinability.

  • Forging Process: Precision open-die (free) forging to produce dense, defect-free blocks with refined grain structure and optimal strength in critical stress zones.

  • Dimensional Range: Customizable dimensions to suit hydraulic cylinder sizes from medium to ultra-large presses.

  • Heat Treatment: Quenching & tempering or normalizing options ensure improved hardness, toughness, and fatigue life in pressurized environments.

Applications:

  • Main cylinder blocks in hydraulic forging presses

  • Extrusion press cylinder housings

  • Heavy-load hydraulic systems in metallurgy, shipbuilding, energy, and forming equipment
