Key to Debottlenecking the RTM Process for Aerostructure Parts

Overcoming limitations in 1K systems

All the current RTM processes for aircraft structures use one-component (1-K materials) systems, that are formulated and premixed by the system provider, which required cold transportation and cold storage during it's life-cycle.

Vacuum-Epoxy-System For Casting-Resin Transformers

  • Operates with high levels of availability
  • Requires virtually no maintenance.
  • Cast-restrain transformers are cast fully automatic first under vacuum and then under pressure.
  • Entire process is microprocessor-controlled.
  • Utilizes a multi-component resin with quartz powder as filler.
  • Constant casting quality from electronic online control of the metering as well as the overall process.

Innovation for product quality and process efficiency: SVT - Silicone Vacuum Treatment - Huebers' new technology for silicone casting

  • SVT is the procedure that from the outset safely guarantees process reliability in the production of absolutely void-free insulators.
  • Components can be used in all container sizes including 1,000 l Ecobulk/IBC.
  • No discontinuity due to changing containers.
  • SVT is the complete prevention of air voids at the very start of the process.
  • No previously required steel mould, a less expensive aluminum alloy can be used as the mould material which replaces more expensive, energy-intensive water heating.

Automatic Pressure Gelation - Innovative Gelation with Direct Injection

  • The APG (automatic pressure gelation) process permits short cycle times thanks to rapid gelation and demoulding with automatic opening and closing of the mould.
  • The APG production system is a continuous mould-filling process via static mixer with a shrinkage compensation unit, a clamping machine with both upper and lower core pullers and a compact arrangement for direct injection.

Perfect Closing - Clamping Machines for the APG Technology

  • Automatic clamping machines permit the productivity advantages of APG systems to be fully realized.
  • The entire system in addition to the mould are easily accessible.
  • They can be tilted and rotated around various axes.
  • The HUEBERS clamping machines start with the basic model, and can be rapidly retooled and enhanced for other APG moulds.
