Tecnomatix software helps automotive supplier save time and money with knowledge re-use

By Stephanie Aldrete


Guangxi Yuchai Group possesses more than 30 wholly-owned subsidiaries and has a reputation as a capital of green power in China.  Yuchai, producer of internal combustion engines and construction engines and construction machines, has attained an annual average growth rate of more than 30 percent.  Yachai’s engine product line covers a wide range of applications, and their success has made Yachai engines the first choice for powering vehicles, construction machinery and agricultural machinery in China.


Yuchai developed much of its product line using a 2D design methodology but as product data increased, that methodology created many information islands. When process designers made changes, they could not use their past experience efficiently or accurately, but had to enter data repeatedly.  This dilemma significantly reduced productivity which led the company to search for a solution that would reduce the delivery cycle.

Solutions and Results:

Initial attempts to solve problems failed due to implementing non-integrated systems with a great deal of redundancy.  Yuchai found what they needed with Siemens integrated solutions that created a unified R&D platform based on NX, Tecnomatix and Teamcenter software.  On this foundation, Yuchai developed a complete R&D process featuring standardized tasks and work templates.  It consolidated knowledge into the R&D process, and established an integrated system between R&D and other systems and databases.

With Tecnomatix software, Yuchai streamlines activities such as primary process planning, logistics and process lay-out, saving both time and money. Introducing Tecnomatix and other new systems is essential to Yuchai’s success in information-based and digital manufacturing.

Siemens PLM Software provides Yuchai with a complete design, data management and manufacturing engineering solution establishing a relatively comprehensive PLM platform.  The software has created a foundation that has made the successful transition from a traditional to a digital R&D process.They now have better collaboration and control across functions, including R&D, process, production, purchasing, sales, finance and so on.  Now, complaints are rare, and they have attained substantial improvements in efficiency overall. The integrated Siemens digital solutions have brought great benefits to Yuchai.
