Get all the material data you need from us, featuring key technical insights like mechanical properties, complemented by thorough processing instructions and professional recommendations. We're here to help you efficiently turn TAFNEX™ products into high-quality components. Don't hesitate to request any specific data you might need.

Sample material
+ Read more

Choosing the right material for a specific application often requires more than just theoretical data. We provide tailored TAFNEX™ sample materials for your material testing and processing trials.

For those interested in TAFNEX™ Design Sheets, we also offer a design folder with hand samples showcasing various designs to help you find your favorite style.

Cost calculation
+ Read more

Alongside technical and visual considerations, economic factors are equally vital. We assist you in evaluating the economic feasibility of potential production scenarios. While prices for TAFNEX™ UD Tape and Compound are mostly set, other TAFNEX™ products, being custom-made, require scenario-specific pricing calculations. We perform these calculations to provide you with the most accurate material pricing possible. Additionally, based on the manufacturing process, we can offer an estimate of the component costs. Don't hesitate to get in touch for a comprehensive cost calculation specific to your production scenario.

Engineering support
Product design
+ Read more

We assist you throughout the product design process, which typically begins with the fundamental material concept. With the extensive TAFNEX™ product portfolio, multiple options are available for creating a component - ranging from local reinforcement with UD tape to full-surface production using one of our sheet materials. We will guide you through the various possibilities and offer expert advice to help you find the best solution. This support can also cover the detailed design of the product, should you require it.

Simulation
+ Read more

Finding the optimal layer structure of a TAFNEX™ Sheet for a specific application can be quite complex. Instead of resorting to time-consuming and costly trial and error, we leverage the simulation expertise of ARRK Engineering. For instance, by simulating critical load scenarios, we can efficiently identify the optimal TAFNEX™ material concept for your application without physically testing a single material. Feel free to conduct your own simulations as well. A TAFNEX™ material card is available for the following simulation tools:

  • LS-Dyna
  • SimuDrape & SimuWarp (Abaqus add-ons)
Material testing

While our database already includes a wealth of TAFNEX™ material data, there are situations that call for extra information. Thanks to the material testing capabilities of ARRK Engineering, we are equipped to provide any supplementary data you require. Whether it's conventional data for a unique material combination or unconventional data for a standard material, we have you covered.

Production support
Prototyping
+ Read more

Leveraging years of experience at ARRK SPG, we can cover the crucial first step towards mass production: prototyping. ARRK SPG supports clients with every step throughout their development phase toward industrialization and series production. With deep in-house expertise in CNC machining, additive manufacturing, vacuum casting, and injection molding, ARRK SPG turns complex designs into high-quality prototypes quickly and reliably. Whether milling functional parts from production-grade block materials, casting soft-touch or multi-material PU components, or integrating printed electronics via in-mold decoration, true production intent is replicated from the start. By combining advanced tooling methods like FastTool®, silicone tooling for PU casting, and hybrid assemblies with foils or composite inserts, we give engineers maximum freedom to test, iterate, and validate designs — reducing development risks and shortening time-to-market.

Low volume production
+ Read more

Achieving cost-effective production for very low volumes can be challenging, especially with thermoplastic composites like TAFNEX™. ARRK SPG bridges the gap between prototyping and series production by offering cost-efficient, scalable manufacturing solutions suitable for low volumes. Alongside vacuum casting and CNC milling as flexible options for small batch production ARRK SPG also provides injection molding using aluminium and rapid steel tools — including 2-/3-shot overmolding, gas injection, and IMD/IML/FIM for functional integration. Their expertise extends to thermoforming, PU foaming, D-LFT, and MuCell®, enabling lightweight, durable, and sustainable solutions. With technologies tailored for demanding composite materials like TAFNEX™, ARRK SPG delivers production-grade quality while maintaining design freedom. Whether integrating functional foils, reinforcing inserts, or decorative finishes, ARRK SPG's approach ensures short lead times, high technical performance, and adaptability to evolving project requirements.

Serial production support

Although we are primarily a material supplier, we can still assist you in setting up serial production. Thanks to our years of experience in thermoplastic composites, we have built a network that we can leverage. Are you looking to invest in machine technology for manufacturing components from TAFNEX™? We can connect you with relevant machine manufacturers. Would you prefer to have the components produced externally? We can link you with production companies that have the required expertise.
