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
