JSCQ Precision Transmission Technology Corporation is committed to the R&D and manufacturing of high-precision transmission forgings.
The main products are automotive steering system assemblies, engine connecting rods, steering gears, intermediate shafts, motor shafts and steel pistons, gear blank forgings,titanium alloy precision forgings…
The forged hollow shaft produced using radial precision cold forging technology broken foreign monopolies, achieved 100% localization of process design, mold design and manufacturing.
The use of radial precision cold forging technology to produce automotive hollow shafts, steering shafts and other parts can achieve a material utilization rate of up to 95%, reduce weight by more than 40%, and is one of the important ways for lightweight and green manufacturing of automotive components.

The parts formed by cold precision forging technology with excellent quality
Unlike traditional metal parts that are mainly machined by turning, radial forging transmits high forces through surface contact, changes the diameter of the workpiece through deformation, and easily controls the shape and size of the workpiece, avoiding metal waste generated by chip processing and shape errors caused by high temperatures.
The automotive parts processed using this technology save raw material costs, improve surface quality and accuracy, and are very popular in the market.
In this way, the newly established Construction Transmission Company has determined to adhere to the research and manufacturing of hollow and lightweight parts, and to use radial cold precision forging technology to produce hollow steering shafts for automobiles.
In 2013, JSCQ purchased precision forging machines imported from Germany and built the first radial precision cold forging hollow shaft production line. In 2014, the company successfully developed a forged hollow shaft and entered the supply chain of Nexteer Automotive Systems.
New Process: Independent Innovation
In Europe and America, precision cold forging to manufacture a hollow shaft requires 5 cold forging processes to be qualified. JSCQ’s technology and production process team, after dozens of research and experiments, has shortened the original five foreign processes to three processes, reducing manufacturing costs by more than 20%, and achieving the localization of low-carbon steel materials for hollow steering shafts.
In 2023, it achieved annual sales of 10 million units, with a market share of about 24%, ranking third in China’s market share.
JSCQ gradually achieved independent research and development of tooling and molds
Established a leading position in radial cold precision forging technology in the automotive parts industry, possessing core technology, gradually entering internationally renowned automotive parts supply systems such as Bosch,Nexteer,ThyssenKrupp and ZF and actively participating in global market competition.
