Aerospace

Structural bonding of aircraft components, edge sealing, shimming, honeycomb filling or seal cap respectively rivet sealing in aerospace: ViscoTec dosing systems achieve high-precision dosing results in the aviation and space sector. This makes them the perfect component in your production process. As a specialist in dosing technology ViscoTec concentrates on automated application of various adhesives and glues, sealants and core masses for suppliers and OEMs of the aerospace industry and guarantees high process reliability at the same time. Due to extremely gentle product handling even shear-sensitive and compressible fluids can be dosed perfectly.

Mobile shimming

Mobile shimming in the aerospace industry

Succesfully implemented in several applications Europe-wide: The semi-automatic ViscoTec shimming station as a mobile system for reliable on demand mixing and dosing of a two-component epoxy resin. The dosing onto the part is volumetrically. It will directly be stucked in fuselage or tail unit structures within the next process step. The storage of the components on a movable platform guarantees highest flexibility for the operator at any time of the process.

Your advantages at a glance:

  • Handling of high viscosities
  • No need for extensive premixing
  • Mixing happens „just in time“
  • Easy operation by foot switch
  • Repeatable dosing results
Mix-on-demand filling stations

Mix-on-demand filling stations

Processing two-component materials out of so-called premix-cartridges is common in the aerospace sector: For the customer it implicates high acquisition costs on one side and material waste of the remaining quantity on the other side. With ViscoTec filling stations epoxy resins, polysulfides, colors and others can be removed from larger container sizes and filled in the exact needed amount on-demand.

 

Your advantages at a glance:

  • Maximum processing time available
  • Material withdrawal out of bulk packs
  • Adjustable mixing ratio
  • Reduction of cycle times in the production process
  • Cost reduction due to minimal waste
Edge sealing for wing shells & landing flaps

Edge sealing for wing shells & landing flaps

Wing shells, side shells and fuselage sections are increasingly being produced from carbon-fibre and bonded to each other within the production process. After the bonding process a slot or open edges remain at many components. Those have to be filled respectively sealed. ViscoTec defies short pot lives and fluids which are complex to handle and serves this type of application successfully.

Your advantages at a glance:

  • Gentle handling of fillers, like hollow microspheres
  • Correct mixing ratio for two-component materials
  • Process reliability due to dosing pressure monitoring
  • Material withdrawal out of any containers
  • Bead without air entrapment possible
Filling and reinforcement of honeycomb structures

Filling and reinforcement of honeycomb structures

Honeycomb structures are used in many areas of an aircraft (stowage compartments, interiors, tail units, wings). Within the production process these honeycomb or sandwich structures are often filled for reinforcement purposes. One or two component epoxy resins with a high share of hollow microspheres – plastic or glass – are typical materials to be used.

Your advantages at a glance:

  • Non-destructive fluid handling
  • Reliable application due to volumetric dosing
  • Bonding of honeycomb structures
  • Viscosity-independent dispensing
  • Repeatability of 99 %
