Our rotary screen features:
Open area up to 18% ,there is no factory in china can make it except our factory,it
help smooth throughout of dyestuff paste, so that printing speed
and efficiency of printing machine can be ascended,experiments have
proved that up to 19% of paste volume can be saved at multiple
printing mills around the world.
Use 6 times stripping by water jet or LEN,by collecting the data from thousand
of experiments.Our screen also SULFUR-FREE and with excellent
brittleness,a convenient way to test the brittleness is the
so-called "lighter test": a piece of screen sample burnt by lighter
flame for 10 seconds, bend the screens sample to see if it breaks
at the burnt spot. our screens will not broken.
What is rotary screen printing?
Rotary screen printing is so named because it uses a cylindrical
screen that rotates in a fixed position rather than a flat screen
that is raised and lowered over the same print location. Rotary
presses place the squeegee within the screen. These machines are
designed for roll-to-roll (web) printing on flexible materials
ranging from narrow web films to wide-format roll textiles.
In short, rotary printing is a continuous, stepless image-transfer
method. The geometry of the screen and the position of the squeegee
within the screen combine to provide both the screen-flooding and
image-transfer functions in a single smooth operation that repeats
with every revolution of the screen.
The squeegee on a rotary press is in a fixed position with its edge
making contact with the inside surface of the screen precisely at
the point where the screen, substrate, and impression roller come
together (Figure 1). Ink is automatically fed into the center of
the screen and collects in a wedge-shaped "well" formed by the
leading side of the squeegee and the screen's interior surface. The
motion of the screen causes this bead of ink to roll, which forces
ink into stencil openings, essentially flooding the screen without
requiring a floodbar. The squeegee then shears the ink as the
stencil and substrate come into contact, allowing the ink to
transfer cleanly to the material.
In rotary printing, the web travels at a consistent speed between
the screen and a steel or rubber impression roller immediately
below the screen. (The impression roller serves the same function
as the press bed on a flatbed press.) As the web passes through the
rotary unit, the screen spins at a rate that identically matches
the speed of substrate movement.

Your smart purchase for fantastic pattern
High mesh nickel screens bring a different pace and intensity to
the printing industry,which set a whole new benchmark for fine
print technology.
Specifications:
The screens are made from the high quanlity Ni metals. The pattern
frame of the screen is orderliness and the character is more tough
and tensile. So the quality of nickel screen is slap-up. The
pattern of the screen is printed symmertrical. Because of the more
tough and tensile character, the screen will be used longer. So the
screen is enable to be operacter, the during long-term and used to
print patterns.
Delivery time :
10-20 days after confirming order,detail delivery date should be
decided according to
production season and order quantity.
