What is Vial capping machine?
Vial
Capping machine are used to apply the flip
off cap or tear off cap on
sealed Glass Vial or bottle. Thus, Vial capping machine is quite imperative
technology in injectable formulation plant since they assured ideal hermetic
seal & hence integrity of Drug / medicine inside the Glass vial or bottle.

Classification of Injectable
Formulation Plant:
These
Injectable formulation plants are broadly divided in following section:
LVP
|
· Large
Volume Parenterals are sterile injectable drugs packaged in containers labelled
as containing more than 100 ml
· Most
are terminally sterilized, but some can be sterilized by filtration and
aseptically processed.
Example :Glass Bottle Like
100 ml Glass bottle , 250 ml Glass Bottle , 500 ml Glass Bottle and 1000 ml
Glass Bottle
|
SVP
|
· Small
Volume Parenterals are sterile injectable drugs packaged in containers labelled
as containing less than 100 mL that are terminally sterilized.
Example: Glass Vial
Like 2ml ,5 ml , 10 ml , 20 ml , 50 ml vial both molded vial as well as
Tubular vial
|
SVS
|
· Small
Volume Parenterals are sterilized by filtration and aseptically processed
|
SVL
|
· Small
Volume Parenteral are sterilized by filtration, aseptically filled and
lyophilized.
|
SLQ
|
· Sterile
liquid (other than suspensions and emulsions)
|
Significance of Vial Capping Machine
· The
vial cap provides final closure element of a sealed vial thus warrant the
integrity of the drug / medicine.
· The
capped vial protects the stopper from outer damage, even as firmly holding stopper
in the fully seated sealed position.
· Quality
vial capping, which can be helpful to paramedical staff during injection
process for smoothly removing the cap without compromising the sterility of
drug.

How Typically Vial Capping Machine
works?
The
basic working of Vial Capping machine is
divided among the following assembly of machine.
· in
feed conveyor
· Feed
worm assembly
· Star
wheel assembly
· Vibrator
cap feeding unit
· Capping
Turret

Load
the Sufficient caps in Vibratory Bowl. The Vials are received from in feed of
conveyor and moved to feed worm assy through the slat conveyor. Feed worm will
create space between two vials, before it is moved in in-feed star wheel.
Vibratory
bowl feeds the cap into the cap chute continuously. If there is no sufficient
caps in chute, NO-CAP sensor (Fiber optic Sensor) will give signal to control
panel & Machine will Stop.
Now,
at In feed star vial index further, take a cap from chute and transfer to Main capping turret wheel. capping head &
Turret rotate clockwise, move down the cam operated capping head one by one
with cap die, hold the vial with cap, rotate further and sealing chuck will
make a thread on cap & seal it properly.
After
completion of cap sealing procedure at last station, capping head moves up and
release the sealed vial. Now at out feed star plate, neat and cleaned capped
vials will index further and transfer to discharge end of conveyor.
Finally,
vial moves to the other on-line connected machine through the conveyor.
Totalizer (Counter) will give information of Total No. of capped/sealed vials.
Type of Vial capping machine
Today,
vial capping machine are available in variety of configuration. They are
normally classified in two categories: Automatic and Semi automatic.
Semi Automatic Vial capping machine
Semi
automatic Vial Capping machine is suitable Engineering solution for start-up
industries where production demand is low. The machine can deliver 30 vial per
minute output depending upon operator proficiency. Qualitative ROPP Capping
result due to use of motorized sealing head.
Single Head Automatic Vial capping
machine
The
Automatic Single Head Vial Capping machine is extension to that of semi
Automatic Vial Capping machine which adopts single motor which is concise &
synchronizes conveyor, star wheels, platform turret. Automatic Single Head vial
Capping machine Rcan deliver 50 Bottle per minute.
Multi Head Vial capping machine:
The
series of Multi head Rotary Vial Capping Machine are dedicated to the capping
of vials for injectable products which is very critical part of the production
process, since they guarantee hermetic seal & hence integrity of the drug
inside the container. Depending upon the output requirement, these series of Multi
head rotary vial capping machine are available in assorted configuration like 4
head, 6 head, 8 head & 12 head. The series of multi head Rotary vial
capping machines can deliver output of 120 Vials per minute to 400 vials per
minute depending upon selected configuration.
