Technology and Development System

NICHIDAI will propose optimum forging technologies with its proprietary systems for development support.

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.

Die-designing Technology

Process designing

NICHIDAI will propose optimum processes to its customers that meet their product specifications and all processes from the proposal of materials to final products.

Die-designing

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.

CAD/CAE/CAM/CAT

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.

Self-development cases

NICHIDAI undertakes contracted development projects from customers and works on collaborative development with them as well as on self-development.

High-precision forming technology that controls the elastic deformation of die

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.

Forming method for hollow components    Technique to decrease forming load with subsidiary tension

Forming load can be decreased in comparison with conventional method by applying subsidiary tension. Thereby, the punch buckling can be prevented.
