RB Series Rotary Blow Moulding Machines
Brief Introduction
RB Series is the latest Rotary Blow Moulding Machine from Ywashun machinery. Our R&D team has dedicated to design the machine by principle of engineered efficiency. Compare to earlier generation, New RB series requires less power due to the small pitch at pre-heater. Thanks to the Optimized clamping unit, the NEW Rotary blow moulding machine has wider operation window. Improved new machine kinematics reach output rates at 1,800 bottles per hour per cavity for light weight 0.5L water application.
Overview
* Preform Feeding and Loading
The recycling unit keeps preforms from getting jammed in the
unscrambler. The star wheel designed feeding unit, provides
easy way of changeover time for different neck preform.
* Linear Oven
Turning 180℃ mandrel guarantee the uniform neck section even
at critical heating oven. Super small pitch design consumes
less power. Unique oven ventilation design make RB series
Blow moulding machine handles various of difficult
application easily.
* Preform and
Bottle Transfer
Wheel
Thanks to the classic designed double cam
telescopic gripper system, it guarantees the
reliability of the movement, and easy to
maintain it.
* Moulds and Mould
Carriers
The mould carriers adopts shell blow mould
design, this reduces the changeover time for
different blow moulds. The Mould carriers
allow the use of all shell type of moulds
form conventional rotary blow moulding
machines; it saves the costs for bottle
producer. The reliable and quick locking
system maximizes the performance of the
mould carriers.
* Blowing
station
Changeable cam stretching curve guider guarantees the
quality of different bottles. Monobloc blowing valves
achieve the fastest and more consistent blowing process.
Bottle neck is protected during the blowing by special
designed sealing unit.
Option
* PID system for heating zone
(Option)
Infrared thermometer automatic detect the temperature of
performs, adjust the temperature of oven automatic. It
avoids the influence of temperature different between day
time and night. Also the system can add additional lamp
alarm unit, It alarms when detected any broken lamps or
aging lamps.
* Special Air Recovery system
(Option)
We know the most production cost for blowing
the bottles is from generating the high
pressure compressed air and reheating the
preforms, In order to reduce the production
cost for the bottler producer,WASHUNhas
introduced Air recovery system. This system
recovers up to 30% of final high pressure
blowing air.
* Air cooling system
(Option)
Thanks to our GM Cai Yuansen, we have
developed air cooling system for hot fill
PET bottles, after high pressure blowing, an
air cooling is introduced it to reduce the
level of PET residual stress, and increase
the rate of PET crystallization . After air
cooling process, PET bottle could stand hot
fill without deformation.
