COLDFORM®

COLDFORM® is the specific simulation software for fasteners, near-shape forging, and sheet metal forming. COLDFORM® simulates the forming process considering every aspect of it, including springback. At the core of COLDFORM® is a unique Elasto-Viscoplastic solver, which resolves all physical equations at once. With COLDFORM®, there is no trade-off in accuracy, and users can immediately look at their final parts for accurate dimensions as well as their conformation to the tolerances described in the standards.

COLDFORM® is an all-inclusive software, which comes by default with the tools analysis, pre-stressed dies, elastic springback for all processes done cold. There is no need to buy additional modules with COLDFORM®. The complete functional software  set of capabilities is provided in one package by default. To understand COLDFORM® licensing policy, please refer to the Licensing Policy section.

TOOL DESIGNER ASSIST

COLDFORM® is the perfect simulation software to assist your tool designers. With COLDFORM®, tool designers can test, analyze, compare, predictvalidate and optimize the final design before going to production.
The end result? The right design the first time, everytime.

The Tools Stress Analysis is another essential part of COLDFORM®. The cold forging process presents many advantages (no material waste, tight tolerances,...), but tool life, unfortunately, is not one of them. This is the reason why it is crucial for tool designers to understand the level of stresses involved in each new design. The final validation of the design will mostly be led by comparing the various stress levels considering that the cost of tooling  is the major item of the total cost.

The Pre-stressed tools are widely used to reduce the amount of stress in the tools during forming. As mentioned above, this is critical to accurately quote a product to a customer, and consequently increase the profit margin of a specific product. COLDFORM® offers the possibility to compare different pre-stressing options. The information that results allows tool designers to choose the best solution.

The automatic reporting is another key feature of COLDFORM® and a significant time saving for engineers. Reporting is an under-estimated task that tool engineers have to perform, and most of the time it is not even included in the design schedule. It is a significant workload for tool designers who have to deliver on time with a supported argumentary justifying their design choices to their manager. COLDFORM® makes reporting easy, fast and painless by providing a customizable automatic reporting system. All design parameters related to parts, tools and equipment are automatically captured into a fully interactive 3D report in a Microsoft Office format. With COLDFORM® automatic reporting, time and energy is spent where it matters most:  the tool design!

COLDFORM® works with all classic formats available in any CAD software (STL, STEP, STP, dxf, x_t,...). To reduce the preparation time for engineers, COLDFORM® features a tool assembly loading system. Designers can export the entire tool assembly from their CAD software, and load it at once in COLDFORM®.

Recommendations

The material definition is the keystone of any simulation. Without accurate material data, there is no accurate simulation result. Transvalor has worked relentlessly since its inception to offer the best material definition information to its customers. It is a 4-prong solution:

* Material Database: COLDFORM® by default comes with a database of more than 200 Materials characterized specifically for cold forging applications. Some of the grades have multiple variations based on their initial state.

* Material Generator: Because most of material grades have many initial states from annealing, and other heat treatment, COLDFORM® offers the possibility to generate your own material. Once generated, the material is stored in your personal database, and can be re-used anytime. The data provided by your supplier is enough to generate the material file: Yield Strength, Ultimate Strength, and Elongation at UTS.

* Materials from JMatPro: JMatPro is a material simulation software from the UK-based company Sente Software. They have designed a well recognized simulation software for the generation of material properties. Transvalor and Sente Software have joined forces, and all material definition files generated with JMatPro are compatible with all our software. It is a great way to avoid the costly expense of material experiments.

* Material Experiments: Transalor has always offered the possibility to generate your own material from experimental data. Any experimental data can be plugged into Transvalor Simulation Solutions.

MOST RELIABLE SOLUTION

Since 1984, Transvalor has repeatedly proven to be the expert in Finite Elements Method (FEM) technologies. Transvalor is born of Research and has maintained a strong association with the Center for Material Forming (CEMEF), a research center of the prestigious MinesParisTech, whose main activities are centered around material forming and numerical computation. This partnership provides a constant flow of advanced scientific developments that translate into innovative new functionalities to Transvalor’s products for the benefit of our customers.

Meshing techniques are at the center of the Transvalor/CEMEF partnership. Meshing and re-meshing techniques are the make-or-brake of FEM simulations. We believe there is no other vendor to this day able to compete with the technology of our re-meshing algorithms, and their reliability.

What it means for the end user, is the guarantee that the simulation will not crash. Crashes are a waste of time, and bring a degree of frustration to the designer. Our philosophy is that crashes have no place in our solutions. The re-meshing technique is the most common reason for crashes. When the process parameters are entered properly, the simulation should complete without incident. Our expertise in this area makes us the most reliable solution on the market. But do not just trust us, try us!

In addition to our re-meshing technique, our solvers have been crash-proofed for over three decades. Our developers pay particular attention to the quality of their coding to ensure the highest solver quality possible. Our development team continuously works on optimizing the code to decrease the computation time, and remove potential risk of conflict.

Finally, our experience in forging (hot, warm, and cold) for more than 30 years makes Transvalor the most knowledgeable, and reliable partner in FEM simulation solutions. We have worked with your industry long enough to understand your priorities, your challenges. We work for you and with you, to bring you the best simulation solution for your business.

OPTIMIZATION

Optimization is a generic term often misconstrued. It is important to explain what we consider optimization, and what COLDFORM® has to offer on this topic.

Optimization allows the designer to produce the best design in a given framework. COLDFORM® optimizer does just that. We use the most advanced genetic algorithm to determine what parameters will be the best fit for what the designer is trying to accomplish. COLDFORM® "tells" the designer which solution is best, instead of just presenting the results of all solutions, as it is the case with a Design Of Experiments (DOE). The DOE is one feature of the optimization in COLDFORM®, but the optimization is way more than just the DOE.

A classic example of optimization is the optimization of a tool design. It is un-realistic to run an optimization from scratch, but once the designer has found her or his "best" design, she or he can run it through the optimizer in order to determine if there is still room for improvement, and in most cases, there is!

Our optimization works with all the major CAD vendors (Solidworks, CATIA, Pro-E,...), and any CAD with a script mode. COLDFORM® optimization modifies the design by communicating back and forth with the CAD software.
