Forged Tie Bar for Injection Machines

High-Strength Forged Shaft for Heavy-Duty Injection Presses Forged tie bars are critical structural machined shafts used in heavy-duty injection molding machines. It connects the fixed and moving platens, ensuring precise alignment and high rigidity during high-pressure injection cycles. Manufactured using open-die forging combined with controlled heat treatment, these tie bars deliver superior strength, fatigue resistance, and long-term reliability compared to cast or bar-stock alternatives. Typical Applications Heavy-duty injection molding machines Industrial presses requiring high platen alignment and rigidity High-load B2B manufacturing environments Non-consumable structural components in extrusion or molding lines Typical Dimensions & Materials Diameter: 120–400 mm Length: 1500 – 4000 mm Weight: 100–600 kg Materials: 42CrMo4 / AISI 4140 – Balanced strength and toughness 34CrNiMo6 / AISI 4340 – Enhanced load capacity for fatigue-critical applications Optional: 40Cr…
