Valve Type 481600
spring 2000 System Flygenring introduced the now well tested Air Valve Type
482400. The succes is now followed up by a new addition to this system. The
Air Valve Type 481600 is developed especially for mouldings with many small
cavities and short cavity distance for instance stack mouldings. It began more
than 30 years ago with the patented needle valve system with spring and
needle valve system with spring, which is developed for high-speed injection
mouldings producing disposable articles and packing is still a good
choice when producing thin-walled parts of simple plastic materials such as
PS, PP or PE where a small injection point makes it possible to establish the
counterpressure needed to hold back the spring during injection.
expanding areas for use of the needle valves in products for household,
technical and medical use have created the need of
a new needle valve system, which is tight even when
producing parts with large wall thickness and corresponding large
System Flygenring presents a new generation of 2-way operated needle valves.
This new construction is provided with a unique turbo air cooled sealing
system, which keep tight without use of too large dimensioned air piston
pressure. The air valve operates with a minimum of mechanical friction. It
operates uncomplicated, with less power and less demands for the dimension of
the gate point.
air valve type 481600:
for most known plastic materials
be build in with only 25 mm between cavities
a needle pressure of 12 kp at 6 bar
with 2 mm standard needle, special needles for glass reinforced material are
colour coded on each valve part (ex. The piston is yellow)
mountable and adjustable while in the moulding using the enclosed set of
order not to damage the air cooled sealing system it is important:
turn on the air piston pressure before heating the hotrunner.
maintain the air piston pressure until the temperature of the hotrunner is
below 150 degree Celsius.
