Fully Automatic Rotary Blow Molding Machine

High speed fully automatic rotayr PET stretch blow molding machine, suitable for water bottle, juice bottle and edible oil bottle, etc.

Main Features

1.       Blow Molding Machine

a)       Machine operation adopts TFT touch screen with multi languages and friendly interface. Speed, shift capacity and technical specifications can be set on the menu.

b)       High efficiency: 2,500 BPH/cavity (500ml water bottle)， servo stretch system.

c)       Double blowing system. Monitoring pressure change curve of each cavity during bottle forming and providing accurate timely parameters, easier for operator to regulate technical parameters and ensure quality stability.

d)       Adopt cam organism and accurate mechanical arm transferring technology with high speed preform and bottle feeding, avoiding contamination.

e)       Cam organism controls mold opening and clamping precisely with special mold clamping boost system and firm mold shelf structure; independent control of blowing parameters of each cavity; malfunction diagnosing function; enhanced neck sealing stability; regulating blowing pressure; stretching bar controls accurate preform axial stretching and 1^st / 2^nd blowing controls vertical stretching; regulating of 1^st / 2^nd blowing precisely ensures ideal distribution of bottle wall thickness.

f)        Heating adopts 10-section far infrared temperature control; each heating lamp of pre-heating and regulating zone can be regulated; timely temperature monitoring system ensures technical stability and accuracy, avoiding over high temperature of outer preform wall; 10-20% electrical power is saved by this heating system.

g)       Air recycling system (optional) may save compressed air by 30-50%.

h)       Technical parameters like heating temperature and blowing time can be set according to different preforms and bottle design.

i)         Fast mold changing (within 2 hours) reduces stop time and increases production efficiency.

j)         Humanized design makes complicated industrial operation get used to habits.

k)       Blowing mold is made of aluminum alloy with oxidization treatment on surface to prolong mold lifespan.

l)         Preform infeed starwheel adopts preform block detecting device. When blocks, preform will be rejected and reset automatically.

m)     Safety door is equipped with alarming device to protect operators.
