DOMO helps manufacturers use recycled PAs for more sustainable mobility
Source:Adsale Plastics Network    Editor:JK    Date:02.Dec.2021

DOMO Chemicals has introduced new material cards to fast-track the adoption of its innovative line of eco-friendly polyamides, TECHNYL 4EARTH. This new feature in DOMO’s advanced predictive simulation platform, MMI TECHNYL Design, will help manufacturers to develop lighter, more cost-effective parts, using peak-performing recycled polyamides.


With many industries eager to reduce their environmental footprint, demand for recycled plastics is growing exponentially. Until recently, however, the often-inconsistent performance of recycled plastics hindered their adoption in the most rigorous applications.

TECHNYL 4EARTH has opened the door to a suite of new applications, providing performance comparable to traditional polyamide 66 (PA66). With TECHNYL 4EARTH, DOMO’s goal is to accelerate the use of sustainable plastics, and broaden the scope of target applications, by providing top-performing grades to meet the most demanding technical requirements.


Advanced predictive simulation


If automakers are to adopt eco-friendly metal-replacement polyamides, however, engineers need to have confidence in their material performance. With DOMO’s MMI TECHNYL Design (Multi-scale modelling, Mechanical simulation, and Injection molding) tools, manufacturers can understand how these new materials will behave in real-life situations before putting new parts into production. 


MMI TECHNYL Design is an advanced predictive platform that harnesses DOMO’s extensive database of key material property measurements to help engineering teams develop lighter, more cost-effective parts using its TECHNYL polyamide materials.


This solution is powered by Digimat, a material modelling software developed and supported by Integrated Computational Materials Engineering (ICME) experts from Hexagon’s Manufacturing Intelligence division. It simulates a wide range of in-use conditions to accurately predict the performance of injection-moulded parts using DOMO-validated digital material cards.


Full range of models 


To support the wider adoption of recycled grades, a more complete range of material behaviour models is essential. DOMO has created no less than 700 models for its TECHNYL 4EARTH A4E 218 V30, TECHNYL 4EARTH A4E 218 V35 and TECHNYL 4EARTH A4E 218 V50 BK 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, including failure prediction, modal analysis, crash, noise, vibration and harshness (NVH), and thermal dilation. Additionally, lifecycle analysis (LCA) of the product is also available.


DOMO has built one of the largest databases in the plastics industry, with over 42,000 files available in Digimat, covering more than 50 grades in PA6 and PA66. Moreover, these “material cards” are not just limited to static load, but also cover tests on a wide range of dynamic parameters.


The files from this advanced database are made available to customers that have access to Digimat MX (Hexagon’s Material eXchange platform that enables customers to request validated proprietary material models within the software); alternatively, DOMO can perform the simulation on the customer’s behalf.


The Digimat database covers a full range of recycled, as well as virgin materials, and the files can be sorted by tags such as eco-friendly, or post-consumer.
