An Integrated stamping tool Simulation System that Supports Die Designing from the Concept Stage to the Final Stage

Responding to various issues related to stamping tool component fabrication

Manufacturing stamping tool components poses a number of challenges, including Crack and wrinkling of sheet materials, poor forming such as springback, and reduced number of die trials and material yield rate. JSTAMP is designed to solve these stamping tool issues.

In addition to realistically reproducing stamping tool process, JSTAMP has the unique feature that it can use as a countermeasure by outputting the result of the virtual examination to CAD data. It also helps to reduce die development lead time and cost by providing appropriate answers without repeating designer-assisted tries and errors.
Integrated support from the first trial to the final stage of designing and support complex manufacturing step, difficult forming material, and state-of-the-art construction methods make it applicable to many challenges related to the fabrication of pressed tooling components. "

Experience and know-how to support stamping tool CAE

JSOL has approximately 30 years of experience in providing stamping simulation software and technical support. Particularly in the automotive industry, we support the introduction and establishment of simulations for mass-production forming for body components, and have received high reputation from many customers.

Our strengths are not just software-operating descriptions, but also point, which can support problem solving from the viewpoint of "simulations that can be used in practice." For example, it supports accurate remediation measures by providing appropriate simulation requirements and outcome assessment suggestions for on-site issues such as board breaks, wrinkles, springback, and forming loading.

In addition, we will provide technical information based on our simulation know-how and industry trends, educational training, and individual consulting. Through these efforts, we will provide comprehensive support for the promotion of customer retention and utilization within the company. Based on our accumulated knowledge and a wealth of examples of introductions, we have put in place a system that can respond to a wide range of demands, from customers who are starting to make full-scale use of CAE to senior-level customers who are already operating simulation.

Precise springback analysis

JSTAMP includes a precise springback simulation module with "Yoshida-Uemori model" and "Yoshida's 6th-order yield function". JSTAMP simulation can consider the Bauschinger effect, the SD effect, rate sensitivity and plastic strain dependency of the unloading Young's modulus so that JSTAMP can deal with high-strength steel and alminum alloys.

Hot stamping

Hot stamping is a forming method that has less springback: preheat a sheet material up to austenite temperature first, then perform hot forming, and follow it with tempering and rapid cooling to obtain a high-strength sheet panel. JSTAMP can consider the temperature dependency of a material and the heat transferred to the tool by using thermal - structural interaction analysis.
