Key advantages of DOMO's advanced database services
DOMO’s MMI harnesses an extensive database of key property measurements and is powered by Digimat, an advanced material modeling system developed and supported by Hexagon Manufacturing Intelligence. This system offers a wide range of calculations to simulate in-use conditions realistically and predict the performance of injection-molded parts.
What we provide:
- Unique material data on optimized fiber orientation parameters in the Moldflow and Moldex3D public databases with more than 150 injection material cards
- A robust mechanical data meta-modeling approach backed by more than 15 years of scientific experience and collaboration
- A generalized local failure criterion considering the characteristics of the glass-fiber reinforced material
- The largest range of available conditions for reinforced PA material definitions on the market, including for every temperature and humidity condition
- Most advanced material laws on PA6 and PA66 compounds such as for creep or coolant aging
- Leading provider of vibration (NVH), fatigue and thermal dependency Digimat material files
- Predictive simulation with no safety coefficients to consider or over-designing of parts, saving time and money in development costs
- Proof of concept through our demonstrator parts
Injection data and mechanical material models
With MMI technology, part designers can benefit from advanced mechanical characterizations taking into account the local fiber orientation effect on stiffness and micro-structure failure mechanisms. Please note: as only one strong glass-fiber orientation fully aligned with tensile direction is assessed here, the characterized material appears stiffer than in actual parts.
Material models and measurements
Glass-fiber orientation-based measurements
In the classical approach to generate material data for mechanical simulations, a standard injection molded tensile bar is used. However, this has its limits when it comes to quantifying the anisotropic behavior of glass-fiber reinforced polymers. As only one strong glass-fiber orientation fully aligned with tensile direction is assessed here, the characterized material appears stiffer than in actual parts.
DOMO’s material models for mechanical simulation
Matching material models and mechanical load case is essential for reliable results and to optimize computation time. Thus, the material models for our TECHNYL grades correspond to a variety of load cases. When prediction of local failure is needed, a pseudo-grain-based failure criteria (FPGF) allows detailed insight into the loading of the material and the likelihood of exceeding the glass-fiber orientation-dependent material limits.
Data for rheological and thermal material models for injection molding simulation
The basis of any injection molding simulation is reliable data. To make sure this high-quality data is available, we take advantage of our in-house physical characterization laboratories, and we collaborate with external partners to characterize our TECHNYL® polyamide materials.
Video: Materials cards for TECHNYL® 4EARTH® recycled solutions
DOMO has created no less than 700 models for its TECHNYL® 4EARTH® A4E 218 grades in Digimat, so that engineers can evaluate the performance of parts by embedding a material model within their standard Computer Aided Engineering (CAE) tools. TECHNYL® 4EARTH® A4E 218 grades are heat-stabilized 100% recycled PA66, reinforced respectively with 30%, 35% and 50% glass fibre. This vast range of models enables customers to perform integrative simulations covering an exhaustive array of environmental conditions and load cases. Additionally, lifecycle analysis (LCA) of the product is also available.

Design optimization
LINKING MATERIAL AND INNOVATION
Design optimization
DOMO offers the combination of engineering experience and numerical topological optimization to identify the ideal shape of a part under given loads. Metal replacement and light-weighting are typical use-cases. The software-based topological optimization helps to create fresh ideas for ideal part design and offers a high degree of automatization. All relevant design restrictions can be considered:
In accordance with customer specifications
- Available design space
- Fixation of the part
- Areas with load applied
Respecting the manufacturing principles for the part
- Mold opening directions
- Wall thickness distribution
Weight and cost savings
- Function integration
- Reduce complexity of assembly
- Optimization of material use
With MMI technology, part designers can benefit from advanced mechanical characterizations taking into account the local fiber orientation effect on stiffness and micro-structure failure mechanisms

Molding simulation
LINKING MATERIAL AND INNOVATION
Molding simulation
Based on reliable material measurements, this process can be simulated, evaluated and visualized by DOMO’s simulation team for a full understanding of effects commonly unobservable in a molding tool. A variety of questions can be answered including best gating positions, general filling parameters, best machine settings to reach the shortest possible cycle time, low warpage parts and optimal fiber orientation for mechanical performance. For each step of the molding process, detailed results can be generated:
Filling and packing
- Determine correct gate location and runner layout
- Verify resulting pressure/clamp force in combination with injection molding machine limits
- Compare different material grades
- Determine correct process parameters
Cooling
- Check cooling layout and validate parameters efficiency
- Optimize cycle time
Shrinkage and warpage
- Verify mold design impact on part shrinkage/warpage
- Verify tolerances respect and part functionality
- Assess influence of different gating positions
As for all simulations, data quality is key. Thus, all relevant TECHNYL grades are included in the material databases of the commercially available injection molding software solutions.

Structural simulation
LINKING MATERIAL AND INNOVATION
The most relevant use case for TECHNYL® polyamides is for parts with demanding technical specifications in harsh environmental or chemical conditions from -40°C to more than +200°C, with complex mechanical loads. A complex design and development process then leads to the validation of the parts. Virtual prototyping and virtual testing play an increasingly important role in this process.
Here, MMI integrative mechanical simulation considering local glass-fiber orientation helps to evaluate and reliably prove the performance of the part by using numerical models for the parts and the polyamide material. Different part behaviors can be assessed, starting from calculations of local stresses and strains in the part, up to failure prediction.
And this can be done for different load cases, from static loads up to crash test simulation, thermal loads or fatigue.
Static and dynamic loadings/part type
Use the form below to select between static and dynamic loadings and then choose the part type. We offer the following material model types:
Static loadings
- Elastic models for model analysis
- Elasto-Plastic models
- Elasto-Plastic models taking into account aging with coolants
Dynamic loadings
MMI integrated structural simulation has been supporting engineers for more than 15 years, enabling you to understand the real behavior of parts before moving forward into the production phase. Helping avoid costly re-engineering and development iterations, the MMI process allows you to simulate fiber-reinforced parts made with TECHNYL® materials with unprecedented structural analysis accuracy. Reliable laboratory data enables you to fully exploit key material properties at the lowest cost, optimizing new designs and reducing material usage when redesigning existing parts.
