  • Lightweight Construction: Automatic Dispensing of Void Fillers

    After an extensive two-year test phase, one thing is certain: The static dynamic mixer vipro-DUOMIX from ViscoTec is ideally suited for dispensing complex materials. Via the two-component dispenser the correct mixing ratio can be set, the mixing is homogeneous and the hollow spheres in the materials are not destroyed during the mixing and dispensing process. The vipro-DUOMIX is therefore perfectly compatible with the products.
    “At Huntsman, we are committed to advancing technology and looking for new solutions for the aerospace industry. We regularly conduct customer research to understand how we can better meet the demanding needs of the industry,” said John Fraser, Global Director Marketing Aerospace. “As OEMs strive to improve production performance, the entire aerospace value chain is under pressure to improve productivity. For the end user of void fillers, this means more than just products that cure faster. It also means investing in the automation of previously manual processes. Thanks to the close cooperation with ViscoTec, we are now able to offer our customers this next level of support”.
    “The aerospace industry continues to strive for lightweight solutions to maximize fuel efficiency and reduce costs,” says Simon Widderich, Business Development Manager Aerospace at ViscoTec. “Our static-dynamic mixer is particularly suitable for compressible materials where the back pressure has to be kept as low as possible. The hollow spheres in some of the Huntsman products we tested play an important role for the characteristics of low-density fillers. Avoiding compression is essential to ensure process reliability as well as to maintain the mechanical properties required for aerospace applications”.

  • Automated Honeycomb Potting in the Aerospace Industry

    The Swiss company Von Roll, has developed a filler for honeycomb structures. The special feature of this new, shear-sensitive and highly viscous material is that it can be stored at room temperature, has a low density and is interspersed with hollow glass microspheres to achieve an end product with a reduced weight.

    ViscoTec should extensively test the automated processability of the new filler during the development process. And this with a pre-defined volume flow whilst simultaneously, gently handling the sensitive material.

    Together with the Dutch company Airborne, which offers solutions for the automation of production processes, was it possible to fill the honeycombs fully automatically. Built into a robotic dispensing cell, ViscoTec’s dispensers can carry out precise dispensing – at various locations and with various geometries. This can be realized due to the programming of the robotic as well as ViscoTec’s individual nozzle design.
    Arno van Mourik, CEO of Airborne, says: “Our goal is to offer our customers a significant cost reduction through increased accuracy and repeatability of potting, drastically reducing material waste and reducing manual labor and non-conformities. That’s why we’re working on several automated and digital solutions.”

    “We are pleased to be able to offer a completely new generation of core filler that is superior to previous solutions in every way. The new formulation offers excellent processability, very long shelf life, requires no cooling and is completely free of harmful halogens and anhydrides,” says Dr. Christian Hennerkes, CEO of Von Roll.

    “The close cooperation between Airborne, Von Roll and ViscoTec enables us to offer a complete solution: An automated dispensing system for customers who require a significant increase in productivity and output,” says Simon Widderich, Business Development Manager Aerospace at ViscoTec.

  • Impregnation: Application of Low Viscosity Resin Masses – Continuous, pulsation-free dispensing flow in the production of electric motors

    By trickling or impregnating the rotating drive components, the coils are provided with a protective layer. This process later improves the performance of the motors and generally extends their service life. After curing, the applied resin becomes a hard-elastic moulding material. It retains its good mechanical and electrical properties even at high temperatures. It insulates, prevents vibrations and the coils become more robust.

    In order for the resin masses to harden, they – and also the stators – must be heated. This requires perfect process reliability. The components are either charged with electricity (electricity heat / induction) or heated in special industrial furnaces (circulating air heat) in so-called impregnation machines or trickle systems. The aim is a perfect trickle result and a precise flow of the resins between the windings of the coil.

    ViscoTec dispensing systems are excellently suited for the application of resin masses. They can easily be integrated into existing production lines. However, they are also impressive in newly designed customer-specific systems.

    rickling is impressive in many respects: Precise dispensing results in specific material consumption per component. This ensures optimum impregnation. Constant and automatic processes are created. In addition, the resin is perfectly distributed on the coils. This in turn means reliable electrical insulation and improved thermal conductivity.

    The proven technology in ViscoTec products ensures the highest quality and maximum production output.

  • Automated Insert Potting – Bonding of inserts in the aerospace industry

    However, in order to remain competitive in the future, certain production processes must be continuously optimized. ViscoTec also contributes to part of this optimization: ViscoTec has realized automated insert potting, also known as insert bonding.

    Threaded inserts are used in lightweight sandwich panels in the aerospace industry. After positioning, the bonding process will be accomplished. These can then be used to screw the panels together or fasten various components. The number of such inserts in a satellite, for example, is several thousand.

    The current process can be described as follows: Holes are drilled into the panels, into which the inserts are then placed manually. Using a cartridge, the insert is then filled by a worker – also manually – through one of the two holes. As soon as material emerges from the vent hole, the operator stops the material discharge.

    This process essentially has three major disadvantages:
    - Excessive time consumed by manual filling of several thousand inserts
    - High material waste, due to relaxation of the material
    - High material costs through the use of cartridges

    With ViscoTec dispensing technology, the filling process can be mapped automatically. The dispensing is carried out with absolute precision, which means that a significant amount of material can be saved. In addition, material can be supplied from large containers, which in turn lowers purchase prices. Another important advantage: As a rule, there are no new specifications because no changes are made to the actual process.
    Either a precisely defined quantity can be automatically introduced, or the dispensing quantity is carried out individually, for example with the aid of a camera system. The system detects as soon as material emerges from the vent hole and immediately transmits a stop signal to the dispensing unit. ViscoTec is specialized in solving difficult applications. Perfect solutions are created in close cooperation with customers and machine integrators.
