Integrated Forming Simulation System for
Virtual Tool Shop
Convenient, Accurate, and Robust
JSTAMP/NV is an integrated forming simulation system for virtual tool shop based on IT environment.
- JSTAMP/NV was firstly programmed for automobile die-tool engineers by JSOL Corporation in 1996.
As an integrated forming simulation system for virtual tool shop the JSTAMP/NV meets the various industrial needs from the engineers of automobile, electronics, iron and steel, etc. The JSTAMP/NV gives convenience to engineers, reliability to products,and robustness to tool shop via the advanced technology of the JRI Solutions Limited.
- JSTAMP/NV is widely used in many companies, mainly automobile companies and their suppliers, electronics, and steel/iron companies in Japan. The JSTAMP/NV will be the long-term solution of forming simulation software to
companies who want to get reliability and efficiency through CAE technology as in Japan.
- JSTAMP/NV includes various robust solvers, LS-DYNA, JOH/NIKE, and HYSTAMP,
which are being renewed progressively.
