The Austrian SME is a start-up (founded in 2015) active in the plastic industry.
In the fields of aerospace, automotive and engineering, big blocks from polyurethane or epoxy resins are used for 3D-modelling or tooling. It is state of the art to produce these blocks from standardized plates, which are glued together and milled to the final contour. This method leads to a whole list of disadvantages:
- By glueing standardized plates, only a very rough approximation of the desired model is possible.
- Due to this fact, the milling itself is time consuming.
- Additionally much more non-recyclable material than necessary is wasted.
- Natural gaps appear in the glued areas, thus reducing the optical and mechanical properties of the product.
- Within these gaps air bubbles or shrink holes can appear, leading to even more problems.
Alternative technologies like injection molding or 3D-printing cannot be used for block production based on their lack in flexibility or their inability to produce bigger parts respectively.
These problems generated the motivation to develop a completely new approach to produce blocks primarily from polyurethanes but also from epoxy resins. A casting process using an adjustable mold can manufacture blocks with a contour quite close to the final structure rather than just roughly approaching it like in the plate glueing process.
Usually the density and the shore-d hardness are the most important material features for customers. In general all material data can be freely adjusted within the physical limits. The lowest density is 0.7 g/cm³ with a shore-d hardness of 66, the highest density is 1.8 g/cm³, which leads to a shore-d value of 86. Other material properties have as well been evaluated and are available on material data sheets.
The Austrian SME is looking for partners for the commercialization of the product through a commercial agreement with technical assistance. (Industrial) Partners of any size from all regions are sought who have a strong knowledge, understanding and demand of the polyurethane (plates) technique (e.g.in the area of aerospace, automotive, design, architecture, ship building, tooling, 3D-modelling, etc.). Furthermore, partners are sought who are willing to apply the novel system and give feedback for further development and optimization of the product.
