What is Cadmould Flex?

Cadmould Flex is SIMCON’s new subscription-based version of its injection molding simulation software CADMOULD. It combines fast and highly accurate 3D-F simulation with a modern interface, flexible runtimes, and automatic license management.

How is Cadmould Flex different from a classical CADMOULD license?

Unlike perpetual licenses, Cadmould Flex uses a flexible subscription model. Users can choose 1-, 12-, or 36-month terms, freely combine modules, and easily upgrade or expand — with no hardware dongles or manual activation required.

What advantages does Cadmould Flex offer to simulation specialists?

Simulation engineers benefit from an intuitive interface, faster computation through the proprietary 3D-F algorithm, and AI-assisted optimization with Varimos AI. It helps identify root causes of filling, packing, and warpage issues and find optimal design and process settings quickly.

Which Cadmould Flex plans are available?

Cadmould Flex is available in five tiers: Viewer, Flex Basic, Flex Advanced, Flex Premium, and Flex Enterprise. Each tier offers a defined scope — from visualization and filling simulation up to full 3D thermals, warpage, HPC computing, and Varimos AI optimization.

What is the 3D-F algorithm?

3D-F is SIMCON’s proprietary simulation algorithm that combines the accuracy of full 3D volumetric models with the speed of shell or midplane methods. It delivers a superior speed-to-accuracy ratio compared with traditional simulation kernels.

How does Varimos AI assist the simulation process?

Varimos AI automatically analyzes cause-and-effect relationships between geometry, process parameters, and quality results. It builds smart Design-of-Experiments (DoE) studies, identifies the main influencing factors, and proposes optimized parameter combinations.

Can non-experts use Cadmould Flex effectively?

Yes. The Basic and Advanced tiers are designed for beginners and occasional users. Guided workflows, AI-based assistance, and clear visualizations make it easy to achieve reliable simulation results without deep simulation expertise.

Which contract durations and payment options are available?

Users can choose between 1-, 12-, or 36-month terms. Longer contracts offer lower monthly rates. Payment can be made monthly or annually via credit card or invoice, depending on the plan.

What are the system requirements for Cadmould Flex?

Cadmould Flex runs on Windows 10 or 11 (64-bit). Recommended: at least 16 GB RAM, SSD storage, and an OpenGL-compatible GPU. Flex Enterprise users can additionally run high-performance computations on local HPC servers.

How can I try Cadmould Flex?

A free 14-day trial of Cadmould Flex Premium is available at https://www.simcon.ai/. The trial includes full feature access for evaluation purposes.

What training or support options does SIMCON provide?

The SIMCON Academy offers e-learning courses, live training, and webinars. Customer success and technical support teams assist with onboarding, licensing, and individual simulation services.

How can I purchase or renew Cadmould Flex?

Cadmould Flex subscriptions can be purchased directly from https://www.simcon.ai or through authorized SIMCON partners. Renewals and upgrades can be activated easily through the customer portal or your assigned Customer Success Manager.

Which industries use Cadmould Flex?

Cadmould Flex is used across automotive, medical, electronics, packaging, and consumer goods industries — anywhere high precision, lightweight design, and process stability are essential.

Why is Cadmould Flex superior to Moldex3D, Autodesk Moldflow, or Sigmasoft?

Cadmould Flex provides a unique combination of speed, precision, and usability. Its proprietary 3D-F algorithm delivers faster simulations than Moldex3D or Sigmasoft without sacrificing accuracy. Compared with Autodesk Moldflow, Cadmould’s results are more consistent for complex 3D geometries and fiber-reinforced materials. Unlike any of these tools, Cadmould Flex natively integrates Varimos AI for automated optimization and Design-of-Experiments, turning simulation insights directly into actionable process parameters. The subscription model also makes enterprise-grade simulation more affordable and easier to scale.

Frequently asked questions

Is it possible to review simulation results with a SIMCON representative virtually?

Yes – we hold virtual meetings in Microsoft Teams. You can join individually or as a group via a conference facility to view and discuss Cadmould simulation results with a SIMCON expert in real time.

What information do I need to set up an injection moulding simulation in Cadmould?

To run a simulation with Cadmould, you’ll need a 3D CAD model of the part and, if possible, the mould components, along with material data such as the polymer type and grade. You’ll also need process parameters including injection speed, melt and mould temperature, cooling system layout, and packing pressure. In addition, mould and machine constraints like clamping force, gate locations, and cycle time are required. If any of these details are unclear or not yet available, our team can assist you in setting up the model.

Is simulation and Design of Experiments (DoE) worth it for my application?

Simulation and DoE offer numerous advantages that apply across different applications and production types. They help reduce costs by detecting errors early, which lowers the need for tool changes and minimizes rejects. At the same time, they save time by determining optimum process parameters before tool tests even begin. Quality is improved as well, since issues like distortion, incomplete filling, and sink marks can be minimized. With VARIMOS, DoE makes it possible to identify stable process windows, which increases production reliability. Simulation is also particularly valuable in smaller series, where it can prevent costly mistakes and ensure error-free production. We would be pleased to advise you individually on your specific application.

Which industries use your simulation solutions?

Our solutions support a wide range of industries that rely on plastic injection moulding, such as automotive, where lightweighting and functional components are key, and medical and healthcare, where precision parts, microfluidics, and devices are essential. We also serve consumer goods, including packaging, appliances, and wearables, as well as electronics, with applications like connectors, housings, and insulation. In addition, we support industrial and aerospace sectors that depend on high-performance plastics and structural parts. If you manufacture plastic parts using injection moulding, we can help you improve quality, reduce costs, and accelerate time-to-market.

What are the benefits of using plastic injection moulding simulation?

Simulation offers many benefits for anyone working with plastic injection moulding. It helps prevent defects by identifying potential issues such as air traps, weld lines, and sink marks before production begins. At the same time, it reduces costs by lowering the need for physical prototyping, which saves both material and tooling expenses. Simulation also supports cycle time optimization by determining the best processing parameters to minimize cycle times and increase efficiency. Quality is improved as well, since warpage and shrinkage can be predicted and mitigated early on. Finally, it contributes to sustainability by reducing material waste and energy consumption through optimized designs and processes.
