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 Mixing & Metering: Electrical Industry

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.

Vacuum Mixing & Metering: Electronic Industry

Precision Continuous Flow System for Large Scale Production of Ignition Coils

8 casting valves able to meter out even very small quantities with maximum precision.
Void-free and dripless casting.
Pre-heating, curing and gelation in the oven-line.
Quality and process control with patented metering-monitoring system.

Silicone Processing - SVT

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.

Oven Systems

Oven Systems From HUEBERS Optimize the Overall Process

HUEBERS high-performance incline-conveyor oven is a cost-favourable solution when the space requirement is not an issue.
HUEBERS automatic batch oven is a very compact form of construction with multi-stage temperature profiles where defined ramps can be set.
HUEBERS stack oven is a compact form of construction, where each pallet passes through exactly the same temperature profile.
HUEBERS serpentine conveyor oven is a relatively compact form of construction where each pallet passes through exactly the same temperature profile resulting in precisely reproducible process conditions.

Compact Solution

The COMPACT-Series From HUEBERS – The Large Scale Systems’ Know-How for Small and Medium Lot Production

With COMPACT you can open up attractive niches in the market – primarily in the areas of epoxy, polyester, polyurethane and silicone castings.
With a dual-plunger pump in each vessel, it saves time and permits continuous casting without waiting times and gives higher productivity.
COMPACT allows HUEBERS vacuum mixing and metering know-how available for optimization of quality with small and medium sized production lots.
Flexible- the trolley-mounted compact system can be moved from manufacturing island to manufacturing island.

Automatic Pressure Gelation

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.

APG Clamping Machine

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.
