ISOCO and V Frames sign an exclusivity agreement with LEHVOSS Group

After V Frames has successfully entered mass production of injection-molded carbon composite frames, forks, cockpits and other components for several OEMs, targeting volumes of 1 million components produced at the ISOCO plant in Schmiedefeld, Thuringia by 2027, the major focus of development is to increase the performance of the raw materials. With this step future frames can become more light-weight, more impact-resistant and E-modules can be increased from currently 32,000 MPa to up to 50,000 MPa long-term, further increasing the stiffness.

V Frames is already producing the world’s most sustainable bike-frames, reducing the carbon footprint by 64% compared to traditional aluminium frame production according an LCA of the University of Linz, Austria. In addition V Frames and LEHVOSS focus on compounds containing recycled fibers from different industries for any new frame and recycle its products 100% at the end of their lifetime into new bike component products, providing 100% circularity. Supply chains are cut from Asia, as all production is located in Germany and can be arranged basically just-in-time, with a current production capacity of ISOCO of around 3 million frames per year. The dramatically reduced shipping of materials and parts results in a significant carbon footprint reduction. The development cooperation with LEHVOSS will further improve the environmental footprint by introducing biopolymers reinforced with carbon fibers into bike frame and component production for the first time.

Managing Director Michael Müller explains:

“LEHVOSS is an excellent partner for the development, production and testing of high-performance materials. With these steps we could push the limits of our technology to new levels. As an example the Buddy Electric / ISOCO X1 frame passed the falling mass test with 23kg at a drop height of 1120mm, a level far beyond the maximum test requirements of any institute and unreachable by most aluminium and traditional carbon frames. The material used for these high-performance frames is now available also for third parties. Additional materials are now developed and in testing, such as world’s first bio-based long carbon fiber material for water injection technology (WIT) assisted injection molding.

Together we now also push the limits of environmental sustainability with introducing bio-based Polyamides reinforced with carbon fibers. We are excited to show the drastic results of the new materials in the performance of our frames and components in the next months and years. The approach of V Frames is to provide the perfect material for any frame geometry, any component developed by V Frames, tailor made.”

”As a global leading material developer the LEHVOSS Group has always been at the forefront in developing high-performance carbon fiber reinforced materials for many different industries. Therefore we supported already for several years the development of V Frames technology and products, continuously testing new materials”, says Rene Warnick, Head of R&D at LEHVOSS. “With bike frames and other bike components V Frames provides some of the most challenging products concerning product safety and performance in this technology segment. The rapid speed of product improvement we see at V Frames makes them the perfect partner for us to raise the benchmarks in the years to come. The new materials introduced in the market under this cooperation represent complete new generation of materials, consisting of world’s first

  • Bio-based long carbon fiber materials for WIT injection molding
  • Bio-based polyamides reinforced with short carbon fibers
  • Economical, ecological and performance  optimized materials based on PA, carbon fiber and glass fiber compounds

This is why LEHVOSS is very glad to announce, after several years of intensive cooperation, to sign an exclusivity agreement for our new materials with V Frames and ISOCO. This includes the tailor-made development of optimized materials in combination with WIT, tailored to the areas of application and their exclusive production for V Frames”, continuous Eric Folz, Senior Business Development Manager at LEHVOSS.

All materials developed and tested in the cooperation are available for purchase. For details please contact V Frames and LEHVOSS. Material data sheets are available on request.

To make 3D printing more sustainable, LEHVOSS Group, Thought3D / Magigoo / Drywise, and Ultimaker the global leader in professional 3D printing have partnered up with Aquafil Group an Italian pioneer of the circular economy. The aim of this partnership is to bring to the market a circular PA6 material, that is manufactured from ECONYL® and renewable resources and that can itself be recycled at the end of its useful life into new raw material.

This new circular material is composed for more than 85% of ECONYL (regenerated polyamide 6), chemically recycled by Aquafil, and the remaining part of other polyamides from renewable sources with almost no additives. This compound ensures the possibility, to have 100% chemically recyclable filaments and products in the future. This however means that water uptake in the filament cannot be tuned as it is usually done on the LUVOCOM 3F product range. The affinity to water of this polyamide is so great that the material is no longer printable after just a couple of hours, even when dried and stored in a low-humidity chamber (drybox). This poses a serious challenge for 3D printing, severely limiting its potential.

Drywise is the only filament dryer on the market that enables this material. With its active in-line filament drying architecture, Drywise removes the moisture from the section of filament that is being fed through the dryer to the printer as it is printing. This ensures consistently dried filament is used to print the parts and hence eliminates time-dependent moisture uptake issues. The first and last layers will have the same material quality, regardless of the state in which the filament started. Drywise requires minimal user input and only requires a very short setup time to initiate printing. As this material cannot receive additives for thermal stabilization, not submitting the filament to multiple drying cycles is essential to prevent material degradation as well, which makes the Drywise dryer a great fit as it only dries the material which will be used.

Our supplier BRISIL has developed a patented process for the resource-efficient production of "green" silicas from biomass (rice husks), which are used as functional fillers in tyres, shoe soles, conveyor belts and cables. Other potential applications for silicas are in the area of paints & varnishes or in the production of toothpastes.

Currently, there is a production plant in the Indian district of Gujarat with a capacity of 7,400 tpa. Further production plants in Asia are being planned.

A REACh registration for this product series will be completed in the near future.

Currently, different types (specific surface areas of 130-200 m2/g) are produced, which are characterised by a positive 'ecological footprint' and a very good price/performance ratio.

UPM Biochemicals, represented by Lehmann&Voss&Co. in Germany, Italy and the UK, remains number one in sustainability in the rubber industry with its filler BioMotion / Renewable Functional Fillers (RFF), as rated by the prestigious European Rubber Journal.

RFF is a new generation of wood-based, sustainable functional fillers. The products can replace fossil or climate-damaging fillers such as carbon black or even mineral fillers.

Many established antioxidants in the rubber industry are highly effective, but they and their degradation products are increasingly associated with environmental problems. 

And they are in danger of being "blacklisted" as SVHCs due to increasingly stringent regulations as well as REACh-related new toxicological findings.

Sustainable remedies can be provided by naturally occurring chemical compounds with antioxidant properties. To evaluate the mode of action of selected representatives of this substance class in elastomer applications, the German Rubber Industry Association (WdK) has set up a joint research project together with the renowned German Institute for Rubber Technology (DIK), to which Lehmann&Voss&Co. belongs in addition to well-known companies of the German rubber industry.

The first orienting investigations show promising interim results. The research project is initially scheduled to last 2 ½ years.

In the medium to long term, our participation in this project will provide us with a know-how edge that will enable us to advise customers and offer our own products / problem solutions.

Our data centre at our new external partner AtlasEdge, Hamburg is powered 100% by green electricity - another step towards a more sustainable future for the LEHVOSS Group!
