Open Die Forging | Carbon & Alloy Steel Forgings Per Drawing

Open Die Forging is our core manufacturing process, ideal for producing high-strength, large-scale components from carbon structural steel and alloy structural steel. We offer custom forging per drawing to meet the unique specifications of heavy machinery, metallurgical equipment, and industrial power transmission systems. Our ISO9001 certified quality system ensures every step—from material cutting and heating to forging, heat treatment, and final inspection—delivers consistent, reliable results.

Our Open Die Forging expertise extends to a full range of critical shaft components, including forged spindle, eccentric shaft, coupling shaft, flange shaft, and gear shaft. These parts are widely used in rolling mills, power generation equipment, and heavy-duty transmission systems, where durability and dimensional accuracy are paramount. Each forged shaft is engineered to withstand extreme mechanical stress, with precise heat treatment and non-destructive testing (NDT) to eliminate internal defects.

We specialize in custom forging per drawing, allowing clients to realize complex geometries from carbon structural steel forgings and alloy structural steel forgings. Whether you require a large backup roll for a rolling mill or a compact eccentric steel sleeve for hydraulic systems, our engineering team works closely with you to optimize the forging process for material efficiency and performance. This flexible approach ensures that even the most specialized components meet your exact technical requirements.

Every Open Die Forging product undergoes rigorous quality checks, including dimensional inspection and ultrasonic testing, to ensure compliance with international standards. Our NDT technical support provides additional peace of mind, verifying the integrity of forgings for critical applications. With decades of experience in open die forging, we combine advanced manufacturing techniques with personalized service to deliver solutions that drive operational efficiency and reliability for our global clients.
