The total engineering system of NICHIDAI is supported by its high-level technological development ability. Having more than 30 technical engineers, NICHIDAI helps its customers realize what they want by using forging die technologies it developed and cutting-edge ICTs. The company also has test presses applied together with its die-making technology to meet a variety of development needs.
NICHIDAI will propose optimum processes to its customers that meet their product specifications and all processes from the proposal of materials to final products.
NICHIDAI provides a comprehensive support to the designs of peripheral equipment and appliances such as die-set as well as of dies using its designing know-how it has developed for a long time and meeting the specifications of its customers’ equipment.
NICHIDAI has adopted ICTs from early on and now uses CAD/CAE/CAM/CAT tools to address customers’ requirements for analysis.
Overview of CAE
CAE technology is applied to designing of forging processes and dies (covering 2D and 3D) as well as contracted and internal developments.
Advantage of CAE
Applied to designing of forging processes and dies (covering 2D and 3D) as well as contracted and internal developments.
Deformation state, forming load required for forming, and enclosing load are checked.
NICHIDAI undertakes contracted development projects from customers and works on collaborative development with them as well as on self-development.
This technology improves the accuracy of out-of-roundness by preventing burrs from being generated on the axis of a cross joint and controlling the elastic deformation of a die occurring at the time of forming.
[Comparison with conventional technologies]
Forming load can be decreased in comparison with conventional method by applying subsidiary tension. Thereby, the punch buckling can be prevented.
[Decrease of forming load with subsidiary tension.]
NICHIDAI is working on basic researches in a variety of fields related to die and forging for the improvement of its elemental technology and the development of new technologies.
