Basic Introduction to Straight Shaft Open-Die Forgings, Forged Components & Factory Customization

Founded in 2011, Shandong Qingliang Mould Technology Co., Ltd. is a professional manufacturer deeply rooted in the field of carbon steel straight shaft open-die forgings. We specialize in providing carbon steel straight shaft open-die forgings with high coaxiality, high straightness, high torsion resistance, excellent fatigue resistance and stable dimensional accuracy for industries including general machinery, metallurgical equipment, mining machinery, conveying equipment, transmission systems and motor main shafts. Our products strictly comply with relevant national and industry standards such as GB/T 33083-2016 Large Carbon Structural Steel Forgings and GB/T 37400.8-2019 Heavy Machinery Forgings and Shaft Forgings. With stable performance, mature technology and high cost performance, we have become a long-term supporting supplier for many equipment manufacturing enterprises, main engine plants, and maintenance and renovation units.

Performance Features of Straight Shaft Open-Die Forgings, Forged Components & Factory Customization

Performance Features of Straight Shaft Forgings

High Forging Ratio Axial Directional Drawing

With a forging ratio of ≥3.5, we adopt carbon steel billets produced by electric furnace smelting + ladle refining. Through a multi-pass composite process including directional drawing, local upsetting/necking and shaft shoulder forming, we ensure the metal flow line is continuously distributed along the axial direction, with full cross-section penetration, eliminating core defects such as porosity, blowholes and inclusions. The metal density reaches ≥99.8%, fundamentally improving the bending resistance and fatigue resistance of the shaft.

Exclusive Heat Treatment for Straight Shafts

We customize heat treatment solutions according to different material grades and load requirements: quenching and tempering / normalizing + tempering for 45# steel, normalizing / annealing for Q235B/Q345B steel. For long straight shafts, we adopt horizontal heat treatment + zoned temperature control, with an internal stress elimination rate of ≥98%, avoiding bending deformation, coaxiality out-of-tolerance and fatigue cracking during processing and application.

Precision Straightening and Pre-Machining

We are equipped with special straightening machines for shaft components, CNC lathes and cylindrical grinding machines. After rough machining, the shaft diameter tolerance is ±0.02~±0.05mm, the straightness ≤0.05mm/m, the coaxiality ≤0.03mm/m, and the surface roughness Ra≤3.2μm. We reserve allowance for subsequent grinding, assembly and chamfering, reducing the processing difficulty and reject rate for downstream customers.
