Design technology that enables to propose planning

FABEST provides creative designs to deliver high precision production based on the policy, "Drawings determine 90% of a die", advocated by the founder and chairman, Nakamura. The level of completeness of a die's design depends on a designer's sensibility even when designing the same part's die. A unique sensibility is necessary in addition to thorough data inquisitions to image the most adequate die architecture based on a part.

Because of the engineers' spirits fostered by the company's culture, we have been able to overcome various difficulties and accumulate achievements to turn the impossible to possible.

We also propose effective productivity solutions to our customers as the specialized die manufacturer, in addition to solutions for assignments.

Simulation

Increase the fine tuning efficiency through simulations

FABEST has been focusing on improving efficiency of development utilizing the CAE analysis with a computer. We have successfully shortened the processes of trials and fine tuning by implementing the die simulation software at an early stage domestically. We are able to predict the possibility of creases, cracks and spring backs generated during pressing and correct them using a computer, which enabled us to produce precise and complete products from the first try.

There are various conditions for die processing simulation and the results depend on how these variables are entered. That's why we accumulate the know-hows based on actual measurement values on the database by receiving feedback from the tries at the factory, like what happens under what conditions. These unique technologies enable us to achieve the higher precision of CAE analysis using software.

A large scale progressive die (PRG) with a high degree of difficulty, High tensile steel plate

Design and simulation technology that make a large scale progression of difficult high tensile parts possible

By pressing a die to a steel plate, it is transformed and becomes a 3 dimensional form. This is the principle of a press work. When the steel plate is transformed, there would be a difference between more expandable and less expandable areas. Since high tensile steel plates especially have complicated material characteristics, multiple trials and corrections with press machines were necessary. Not like common materials, corrections became necessary with high tensile materials due to spring back.

FABEST has ensured the accuracy even with high tensile materials during NC process by conducting CAE analysis. By directly linking our unique database to the simulation software, we made it possible to attain the usage of high tensile steel with transfer and even with the large scale progressive die (PRG) that has a high degree of difficulty.

FABEST's unique FMS

FABEST's unique FMS

Because a die is basically one item product per order, automation and rapid response used to be difficult. FABEST has been working on automation of die productions. We have been applying advanced technology and working on practical application of "FMS" (Fully-automated machining system of module).

"FMS" is the abbreviated name of "automated machining system of modularized unit (block)". Automated productions are possible using NC process machine based on CAD/CAM data that include a die's unit (block) designed by the solid (3D). By processing casting productions in parallel and assembling the block immediately after the cast completion, it can proceed to a try.

"FMS" enables immediate exchange per block. Spare parts' fast delivery becomes ready to support die used in production factories of foreign countries.
