10. Vacuum Pressure Impregnation,
Vacuum Pressure Impregnation (VPI) is a process that uses vacuum and
pressure to seal porous materials with varnish or resin. The process is
used primarily for high-voltage motors and generators to fill gaps in
materials to create a void free insulation in various devices.
Industrial electromechanical equipment is designed for durability to
provide reliable function and increased longevity, but age, temperature,
and environmental factors can degrade porous metals over time. The
process of impregnation seals porous materials with varnish or resin,
improving the function and longevity of equipment, Vacuum Pressure
Impregnation Process
Sloan specializes in vacuum pressure impregnation, which is more
effective than traditional dip-and-bake methods and is better suited to
high voltage motors and generators. Our basic vacuum pressure
impregnation motor repair process comprises several steps.
Preheating
We place the equipment in an oven that heats the equipment and allows
moisture to evaporate. This helps the resin better penetrate the material.
Dry Vacuuming
We remove the equipment from the oven and place it into a vacuum
chamber, which removes air and any remaining moisture.
11. Filling
We fill the chamber with resin, coating the part and filling in all the gaps
and pores in the piece of equipment.
Wet Vacuuming
We reduce the vacuum levels and hold it for a set period of time.
Pressure
We increase pressure within the chamber using dry air, nitrogen, or other
gases. This allows for even deeper penetration of the resin.
Draining
We then vent the pressure, drain the chamber of excess resin, and
remove the part.

The vacuum component of the process is the removal of air that occupies the
migration path commonly known as porosity in cast or pressed metals.
2. The impregnation part of the process is replacing the void with a durable and
stable material suitable for field of use.
Vacuum impregnation prevents the migration of fluids or gases out of or into a
27. manufactured component:
1. From contained areas to the atmosphere as in hydraulic pumps and
transmissions;
5. From adjacent independent passages as in oil and water circuits in an engine
and graphite plates used in fuel cells;
6. And from atmospheric conditions to the internals of a component as in insert
or over-molded plastic connectors, wire, cable and connectorassemblies.
Vacuum impregnation as an industrial process has been in commercial use for
more than 60 years. For the world's largest manufacturers, it continues to be the
preferred process through which to guarantee the pressure-proof, leak-proof,
and corrosion-proof requirements of parts and components in critical operations.

GVP's manually operated Needle Valves are suited for admitting defined, clearly reproducible
gas streams into a vacuum chamber. Needle Valve consists of a Brass housing a regulating
needle of stainless steel and a valve seat made of Brass. In closed position, the needle is passed
against the conical valve seat by a pressing spring. The needle moves in the axial direction. It is
coupled to the actuating knob over a ball bearing.
Application:
Needle Valves are suited for admitting defined, clearly reproducible gas streams into a vacuum
chamber.
Butterfly valves are the most efficient and reliable sealing Isolation valve mechanism under high
vacuum working conditions. A vacuum seal provided around the plate periphery in the main
body of the valve ensures fail proof working of the valve. For efficient working of the valve it is
advised to ensure that the sealing plates are facing atmosphere.Butterfly Valves are of small in
29. terms of thickness which ensures easy and faster passage for air and gases and are ideally suited
for "In-line" isolation purpose. Though the butterfly valve is not intended to be used as an
independent valve, it is widely used as a Baffle Valve in union with a chevron baffle at the top of
a Diffusion Pump. These Butterfly Valves are offered in stainless steel SS-304 non-magnetic
AISI quality high carbon steel chromium plated construction and they can be manually or
pneumatically operated as per customer choice.
Application:
Butterfly Valves are of small in terms of thickness which ensures easy and faster passage for air
and gases and are ideally suited for "In-line" isolation purpose.
GVP's Gate valves have high conductance, and fabricated out of stainless steel SS 304, are
designed for reliability and for use as in-line chamber isolation valves and load lock applications.
These Gate valves are fitted with Neoprene "O" rings as standard and optionally viton o "O"
rings are offered. Viton sealed valves can be baked up to 150 Deg.c under normal mode. These
Gate valves undergo stringent leak detection tests on a Helium Mass Spectrometer for leak
tightness up to 10-10 STD cc/second. HHVGate Valves are offered in several models and can be
operated in both electro pneumatic as well as manual modes. Gate Valves are used immediately
above the mouth of a diffusion pump or above the water-cooled baffles. The closure between the
two sides is made by the movement of a horizontal plate in its own plane, the seal being an
elastomeric. These valves are made in sizes of 1", 2", 4", 6", 8", 10", 20" sizes as a standard
product.
Application:
Designed for reliability and for use as in-line chamber isolation valves and load lock
applications.

We make over 1,200 different electrical feed through in a wide variety of terminations,
maximum voltages, and current carrying capacities.
A major factor in engineering an electric feed through is the type of current and voltage for
which it will be used and the requirements it will have to satisfy with respect to vacuum tightness
and temperature resistance. The manufacturing processes for feed through are discussed in Feed
34. through with organic insulating materials can only be used for lower voltages. Simple cast-resin
feed through are frequently used for moderate current loads, e.g. for measurement currents.
Epoxy resin is very well suited as an insulator and as a vacuum seal for moderate temperatures.
Multi-pole glass-molded feed through to which the leads can be soldered on both sides are
installed in small flanges. There are also versions with tubes through which leads can be inserted
and soldered in place.
This is important when using thermocouples, for example, as solder joints could falsify the
measuring voltage. The feed through are cooled with water for high amperages.
With respect to their insulating resistance, feed through with glass-to-metal fusing are suitable
for high-voltage and weak-current feed through for electronic devices. Feed through with
ceramic insulation offer greater mechanical stability and temperature resistance than glass. In
addition, ceramic (e.g. aluminum oxide) can also be produced in an insulating form that is
suitable for high voltage. This is why ceramic feed through are superior to glass feed through for
high voltages and high performance. Only rigid metal-to-ceramic connections should be
considered for the most rigorous electrical, thermal and vacuum technology requirements.
The voltage level must be taken into account for electric feed through, because gas discharges
and flashover can occur in the vacuum if there are small clearances between conductors with
high voltage differentials. In the vulnerable pressure range between 10-3 und 10 mbar,
appropriate clearances must be provided between high-voltage conductors. Potting with cast
resin can also be useful in this regard.

Vacuum furnace
36. vacuum furnace is a type of furnace that can heat materials, typically metals, to very high
temperatures and carry out processes such as brazing, sintering and heat treatment with high
consistency and low contamination. In a vacuum furnace the product in the furnace is surrounded
by a vacuum. The absence of air or other gases prevents heat transfer with the product through
convection and removes a source of contamination
Application:
1 Maximum occupational safety with one-of-a-kind safety concept
2 Fast, condensation-free drying processes
3 Homogeneous specimen drying
vacuum furnace are:
1. Uniform temperatures in the range 11001500°C (20002800°F).
2. Temperature can be controlled within a small area
3. Low contamination of the product by carbon, oxygen and other gases.
4. Quick cooling (quenching) of product. .
5. The process can be computer controlled to ensure metallurgical repeatability.
