National Engineering Research Center of Die and Mold CAD

Brief Introduction

Approved by the Chinese National Planning Commission and built up on the base of Shanghai Research Institute of Tool and Die Technology in April, 1996, the National Engineering Research Center of Die and Mold CAD (ERC) is a research and development institution that focuses on high-level scientific research and technology transfer in the field of die and mold. The National Digital Manufacturing Technology Center, affiliated to ERC, is mainly engaged in plastic processing technology, digital manufacturing technology and engineering support. A dual-platform aiming at independent innovation mold technology and digital manufacturing technology has been built up.

Currently the ERC has more than 200 staff  members, among which 21 hold PhD degrees, and there are ten full professors including one member of the Chinese Academy of Engineering and one Cheung Kong Chair Professor (part time). The Center has established R&D and production bases in Xujiahui, Zhangjiang High-tech Park and Zhenjiang. It has established wide cooperation with many international companies such as Ford Motor.

    Research Fields

    The research activities mainly focus on:

  • Theory and processes of advanced plasticity forming technologies (behaviors of cold extrusion, fine blanking, new material stamping, constitutive modeling and material failure criteria etc);
  • Numerical simulation of material processing of multi-physical fields (numerical simulation of stamping & springback prediction, simulation composite material forming, microstructure evolution of hot-forming processing etc);
  • Digital intelligent design for customized functionalities and design optimization(deterministic optimization, robust optimization and topology optimization);
  • Limit manufacturing (micro forming and hot forging of large heavy components).


    Research Achievements

  • Auto Cubing: Developed the methodologies and technologies to design and fabricate the functional cubing for automotive industry and to control the dimensional accuracy of thin-walled (the thinnest thickness is 0.34mm) aluminum alloy component, successfully produced the whole functional cubings for the automotive industries.
  • Hot forging of large heavy parts: For the quality control of heavy forgings, proposed a cell model-based void volume prediction method to study the relationship of volumetric deformation of void inside the material with the macroscopic mechanical variables in the forgings during forming. By integrating the method with FE modeling, the evolution of the void can be predicted when numerical simulating the forging process. In addition, by applying the cellular automation method, a simulation method was proposed to predict the dynamic recrystallization and flow stress of high alloyed steels during hot working.
  • Customized industry application software development: Developed the methods and algorithms about knowledge acquisition, knowledge representation, process reasoning and knowledge discovery which were used to develop the knowledge-based process and tooling design support systems for forging, extrusion, fineblanking, sheet metal forming and injection molding based on different CAD platforms, the developed S/W tools have been successfully and widely used in the domestic and oversea die & mold industry, such as Feintool AG from Switzerland, Yamanaka Engineering from Japan and HaiEr mold from China etc. Several function-specific design automation and data integration S/W tools were also developed for shipbuilding industry, automotive industry and machine tool industry which greatly improved the design efficiency.
