Application example: Honeycomb filling & potting
As an expert for dosing technology ViscoTec Pumpen- u. Dosiertechnik focuses primarily on challenging dosing applications in various industries. Due to complex requirements of materials used in aerospace industry, applications in this sector are in general extremely demanding. Different viscosities, thixotropic properties and a high share of solids require a very gentle handling of the applied materials. Particularly fluids filled with polymeric or glass microspheres to reduce their density and weight come along with one of the most challenging properties: Compressibility.
ViscoTec technology at the expoAIR 2017:
To encounter these challenges ViscoTec dispensing systems are based on a specific pump type: The progressive cavity pump. The function of the pump is based on the endless piston principle. It consists essentially of a stainless-steel rotor that performs an eccentric motion in the stator made of elastomer. By opening and closing chambers – identical in their volume – the movement causes an output, which is just as repeatable as exact. All of ViscoTec products rely on this principle and range from material emptying systems (out of cartridges, hobbocks and containers) via material treatment systems to precise dosing equipment.
Application example: Overcoating for seal caps
ViscoTec convinces:
- ViscoTec systems integrate well into automated environment
- ViscoTec supports the industry shift to automated manufacturing practice
- Even shear-sensitive and compressible materials can be handled precisely and reliable
Materials to be processed:
Application example: Edge sealing & bonding composites
Considering aerospace industry from a material supplier perspective, various fluids are used during the production process at supplier and OEM site: 2K epoxy resins for bonding structural elements or sealing applications, 1K epoxy resins for filling honeycombs, 2K polyurethanes for potting, 2K polysulfides for seal cap production or edge protection, just to name a few. ViscoTec benefits from its extensive experience in dealing with those fluids and can help its customer finding the perfect way of application for their individual requirements.
Application examples
- Mix-on-demand filling stations
(2K ink, 2K epoxy, 2K polysulfides) - Mobile shimming (of fuselage and tail unit)
- Sealing (of landing flaps and fuel tanks)
- Potting / grouting (of electromagnetic components)
- Filling and reinforcement (of honeycomb structures)
