Technology Development
Based on design requirements for the next vehicles of automobile manufacturers who are our customers, we offer optimum design proposals. We perform design, trial production, analysis and evaluation by ourselves, and based on the results thereof, we take our responsibilities for the processes from facility production to mass production. Since we perform all the processes from design to mass production by ourselves, we can realize the speedy development of automobiles.
Development / Production Process
01
We explore high-quality, low-cost, and productive products based on the performance required by our customers.
02
We perform data analysis to confirm whether the designed part satisfies the performance as a vehicle. We repeatedly preform design and analysis until the favorable result is obtained.
03
We perform various types of evaluation. There are numerous evaluation items such as strength, rigidity, shocks, sounds, heat resistance, weather resistance, light resistance, chemical resistance, odor, burning, durability, vibration, cooling, withstand voltage, and glass haze.
04
We perform process design realizing both production efficiency and quality for the processes from sheet metal pressing to welding and assembly, and realize stable production through simulation and automation.
05
We establish efficient production lines realizing the safety, maintainability and automation at the same time by integrating facility design, mold design and inspection tool design.
06
We consistently perform, by ourselves, press mold production, welding/assembly facility production, jig production and operation testing of control software from start to finish.
07
We preform pressing, welding and assembly of steel plate parts, and also manufacture various parts such as resin parts.
We perform data analysis to confirm whether the designed part satisfies the performance as a vehicle. We repeatedly preform design and analysis until the favorable result is obtained.
We create the die face data(*) based on the product shape data. The actual press molding is reproduced through numerical simulation, and perform preliminary verification so that the problems such as cracks and wrinkles do not occur after mold production. We perform molding analysis not only for cold-stamped materials, but also for hot-stamped materials.
* Die Face Data
A virtual full-scale model necessary for simulation.
If a crack or a wrinkle occurs during simulation, we modify the die face data and perform analysis again. By repeating this, we can solve problems before the actual production of molds. In addition, by using the die face data of simulation, it becomes possible to shorten the lead time of mold design. Further, since it becomes not necessary to take measures through trial and error after the completion of molds, it is possible to reduce the number of modifying molds.
We can also confirm the amount of spring back(*) during molding analysis. The higher the yield stress is, the higher the amount of spring back is. For this reason, when manufacturing products using high-strength steel plates, we must consider the molding process and method taking spring back into consideration. We can examine what kind of countermeasures are necessary in advance by performing molding analysis, and also here, it leads to the reduction of the number of modifying molds.
* Spring Back
A restoration phenomenon occurring when bending an iron plate by press processing.
It is the important technology to confirm the safety performance in developing and designing body parts such as front side members. Various collision phenomena are reproduced and evaluated on the computer. We perform collision analysis by taking into consideration the roles of respective parts at the time of collisions such as parts for absorbing energy through deformation and parts for protecting occupants with no deformation. Thorough this, we propose suitable lightweight and low-cost structures to our customers.
It is the essential technology to design parts requiring certain strength such as brake pedals and suspension arms. We confirm whether the designed part deforms due to the application of a prescribed load through simulation.
The trial production phase is simplified by strength analysis, and it becomes possible to shorten the development period.
In topology analysis, a computer derives the optimum solution by setting constraints and target strength values to a space to be designed. Novel optimum shapes outside the box lead to new ideas by our designers, and we contribute to the weight reduction.
It is the method of simulating how resins flow in the mold during injection molding. Failures such as filling failures of resins, weld lines and deformations are predicted and prevented to improve the product quality and to optimize the molding conditions.
