PRODUCTS & PROCESSES
In addition, each cabinet is fitted with a side
loading turntable, allowing heavy/bulky
components to be loaded outside the blast
cabinet via forklift or crane if necessary.
The turntable (with a max 300 kg evenly
distributed load) is manually moved into
the blast cabinet on rails and metal bogey
wheels. And once the turntable is within
the blast chamber an external scissor lift, on
the side loading frame, allows the load table
rails to be lowered, allowing the cabinet side
door to be closed, creating a tight seal,
to prevent dust and blast media escaping
into the workshop environment during post
process blasting. Electrically operated door
switches prevent accidental blasting when the
door is open and a timed interlock prevents
operator access, for a pre-determined time,
after blasting ceases to allow dust to be
evacuated to the dust collection unit.
During blasting of AM parts, externally
mounted fluorescent lighting and additional
interior bulkhead lights ensures excellent
observation and visibility through an angled,
toughened glass, viewing window protected
by fine mesh gauze and fitted with quick
change anti-frost sheet.
A nozzle holding bracket gives the operator
the choice of either holding the blast nozzle
and moving it around the component or
placing the pressure blast nozzle in the
bracket leaving both hands free for moving
the component around under the blast
stream. A floating foot pedal is provided for
blast nozzle operation offering convenient
and comfortable foot positioning for
each operator. the dust, blast debris and undersize media to
improve the consistency of finish and extracts
the dust and fines off to the model C800
cartridge filter dust collection unit, whilst the
heavier re-usable blast media flows back
to the pressure pot.
The whole Guyson blast system is completed
with a blast media delivery/extraction system
comprising of a Guyson model CY600/12
Cyclone Reclamator, G55 Pressure Pot and
C800 Dust Collector. the 3D Print/Additive Manufacturing
The 55 litre pressure pot generates the blast
stream (up to four times faster than suction
feed) from the pressure vessel into the
cabinet through heavy duty hose to the blast
nozzle and when the floating foot pedal is
depressed it pressurises the pot and starts the
blast operation; similarly releasing the pedal
de-pressurises the pot and stops the process.
The blast media then passes out of the
cabinet hopper into the cyclone reclamator
which separates out re-usable media from
