processing equipment - Verfahrenstechnik Hübers (aka VTH or Huebers)
Huebers produces a wide range of custom equipment for processing epoxy, polyester,
silicone, polyurethane and many other types of materials.
Examples of Huebers equipment include:
- Vacuum mixing and metering systems for the electrical and electronics industries
- Storage and conveyor systems
- Vacuum dryers
- Vacuum Compounding & Material preparation systems (in-line formulating plant)
- Automatic Pressure Gelation (APG) injection and Mold Clamping machines
- Vacuum Impregnation Equipment
- Laboratory Scale and Specialty Equipment
Applications:
Ignition Coils Insulators
Flyback Transfomers Breakers & Switchgear
Motors & Generators Cast Coil Transformers
Vacuum Mixing & Metering systems for the Electrical & Electronic industries
Huebers' resin casting equipment is unparalleled in terms of its many patented features. These
unique details are demonstrated by its unique material preparation systems, mixing and metering
technology, special degassing techniques, process control and process regulating systems, and
through modular, maintenance-friendly design. All of these features combine to guarantee the
tightest manufacturing tolerances and highest quality of the products cast using Huebers'
equipment.
The unique design of the Huebers' resin casting systems allow the user to obtain reduce raw
material costs, energy usage, personnel and retooling. In addition, Heubers' resin casting
systems are a wise investment since each can be easily converted for other processes and used
for other products or materials.
Quality, Reliability, Economic Efficiency : The advantages of VTH's multicomponent
metering technology
Unique features include:
- Synchronized metering pumps to provide the exact mix ratio needed
- Static Mixer Chilling to allow for production breaks without the concern of resins gelling in
the static mixing nozzle - Solvent free cleaning process
- Micro dispensing with reproducible control to +/- 0.01 grams
- Easily handles abrasive fillers and other troublesome components without added
downtime or equipment wear.
Storage and conveyor systems, &
Vacuum compounding and material preparation systems
Huebers offers all the system components required for quality-optimized material flow. Their
system designs allow raw materials to be purchased more economically and processed more
reliably. The integrated equipment handles all aspects of compounding and material preparation
(ex. filler drying, mixing of all wet & dry ingredients, degassing, and finally dispensing). This
allows the user to do in-house formulating rather than purchasing more costly pre-formulated
resin systems or to custom color or custom modify standard formulations to achieve unique
results.
And because all VTH system components have been designed so that they can be used in a
flexible manner, existing dispensing or processing systems can be integrated into a new system
with expanded capacity. Therefore investments in Huebers equipment don't go to waste as
happens with so many other pieces of industrial equipment
APG - Automatic Pressure Gelation:
Heubers was one of the pioneers in Automatic Pressure Gelation - a casting technique that vastly
improves the throughput and reduces shrinkage in cast epoxy and other polymeric parts. In
contrast to traditional APG techniques using a simple pressure vessel to feed material to the
casting process, VTH employs direct injection. In combination with VTH static mixer and VTH
metering pump technology, the direct injection process increases throughput, reduces waste,
improves part quality and increases economic efficiency.
Clampling Machines:
At VTH optimization of the production process starts with the clamping machine which open, close
and manipulate the mold used in the APG process. VTH clamping machines are designed to be:
- easily accessible from all sides so that the mold is easy to get at
- able to be tilted and rotated around a number of axes
- flexible in terms of the positioning of the core pullers,
- flexible in terms of the positioning of the static mixer,
- able to be enhanced to fully automatic versions for all process steps
