should be connected to FlexiCoat Coating Station.
It is strongly recommended that the air supply to be connected to the
FlexiCoat® Coating Station be clean, dry and free of particles or oil. This is most
important in order to keep the powder free flowing and keep it from
agglomerating which would have an adverse affect on fluidization and
application.

connected to the system.
Electrostatic Technology, Inc. Shatterproof Lamp Powder Coating Line
12 Serial #20444
6 MECHANICAL FUNCTION, SEQUENCE AND DESCRIPTION
6.1 LOAD STATION
Bulbs are manually loaded into the holding fixtures at this point. The holding fixtures
rotate in this station to allow bulbs to be "screwed into" the holding fixtures. Load
Station rotation speed is adjustable.
6.2 CONVEYOR
The Conveyor is a chain on edge system with 154 spindle pins on 8" centers. Bulb
holding fixture sockets are attached to these spindle pins. There are two different
sizes of holding fixture sockets that can be used depending on the type of bulb to be
run; Mogul Sockets and Medium Sockets.
These spindle pins (and holding fixtures) rotate in the Load, Coating and Unload
Stations. Rotation speed in each of these stations is adjustable independent of each
other.
Conveyor speed is also adjustable.
6.3 OVEN
The Oven is an electrically controlled, gas-fired unit with a vertical injection air flow
pattern and centralized return. The blower utilizes a 2 HP motor and has a 3200 CFM
fan rating. The Oven has a 500,000 BTU rating and is capable of a continuous
temperature of 750° F. There are two sections of the Oven, one for pre-heating the
bulbs and one for cure of the powder coating. The Oven Electrical Control Panel is
mounted on the Oven just to the right of the Coating Station.
6.3.1 Pre-Heat Section
Bulbs are pre-heated prior to powder coating to make the glass more conductive
to enhance the uniform electrostatic application of powder.
6.3.2 Cure Section
Bulbs are heated after powder coating to flow and cure the powder.
6.4 FLEXICOAT® COATING STATION
The Coating Station is complete with three Versa-Spray (Electrostatic) Guns and
Controls, a Cloud Containing Hood and a Powder Feed Hopper.
The bulb holding fixtures rotate in this station to allow for uniform deposition of
powder around the circumference of the bulbs. The rotation speed of the bulbs is
adjustable.
Electrostatic Technology, Inc. Shatterproof Lamp Powder Coating Line
Serial #20444 13
6.4.1 Versa-Spray Guns
The three spray guns must be turned on "manually" when the first bulbs are
present in the Coating Station; they will not turn "ON" automatically.
Refer to the Nordson Versa-Spray Gun Manual included in the Appendix of this
Manual for more information on these electrostatic powder spray guns
6.5 FLEXICOAT® POWDER COLLECTOR
The Powder Collector is an automatic blowdown unit with a Fluidizing Hopper to
aerate powder that is reclaimed.
The 500 CFM Powder Collector Module uses a 1 HP motor to drive the Exhaust Fan.
The Exhaust Fan pulls air from the Powder Application Hood into the (2) Cartridge
Filters. The air passes through the Cartridge Filters and is forced through the Final
Filter. The clean, powder free air is returned to the surroundings.
Excess powder (not adhering to the parts) is carried by the air flowing through the
Hood to the Cartridge Filters, where it collects on the outer surfaces. When activated,
the pulse valves force air from the Pulse Valve Air Manifold through the Cartridge
Filter in the opposite direction of normal flow. The pulse airflow cleans accumulated
powder from the Cartridge Filter media. The powder falls to the bottom of the
Collector Module and into a Fluidizing Hopper where it is aerated and fed
continuously back into the Feed Hopper by a Powder Pump.
A Differential Pressure Gauge is located on the side of the Collector Module. This
gauge provides an indication of cleanliness of the Filter Cartridges. A normal reading
would be between 0 and 3.5. A reading above 3.5 would indicate the Filter
Cartridges are not being cleaned well enough. This would require resetting the unit
so the reverse cleaning pulses are more frequent and/or increasing the air pressure to
the pulse circuit.
6.6 FEED HOPPER/FEED HOPPER PUMP
The Feed Hopper is used to load powder into the FlexiCoat® Coating Station. It is
located beside the Coating Machine. It is a metal barrel with pumps, which is
manually loaded with either virgin powder or a combination of virgin and reclaimed
material. Powder is automatically fed into the Versa-Spray Guns by the Feed Hopper
Pumps. The Feed Hopper holds approximately 80 lbs. of powder. Powder is
continuously fluidized in this hopper using dry air to keep the powder dry and fluid.
This will facilitate pumping the powder into the Versa-Spray Guns.
IMPORTANT: DO NOT DROP ANY FOREIGN MATTER INTO THE
POWDER AS THIS WILL JAM THE FEEDER.
Electrostatic Technology, Inc. Shatterproof Lamp Powder Coating Line
14 Serial #20444
6.7 COOLING STATION
An Axial Tube Fan with a 1/2 HP Blower draws air through a tunnel as the bulbs are
conveyed through the Cooling Station. The fan is rated at 1080 CFM. When the
bulbs leave the tunnel they are cool enough to handle by hand.
6.8 UNLOAD STATION
Bulbs are manually unloaded from the holding fixtures at this point. The holding
fixtures rotate in this station to allow bulbs to be "unscrewed from" the holding
fixtures. Unload Station rotation speed is adjustable.
6.9 MAIN CONTROL PANEL
The Main Electrical Cabinet and Main Control Panel are located to the left of the
Coating Station. The Powder Collector, Coating Guns, Conveyor and Spindle
Rotation are all controlled from this point.
