Automatic Injection & Stretch Blow Molding Machine
—One Step Container Forming Solution Expert
Environmental protection
to
reduce the work on operation, packaging, handling and storage, and cut down
energy consumption, and with compact structure to occupy less space;
Cleanness
one step on product forming to avoid more pollution;
Reliability
by using one step on forming to reach a minimum rate of defective products;
Good forming
precise positioning on bottle mouth, light weight on bottles, better
parting line; adapting to abnormal shapes and high quality requirements on
appearance..
Information
Along
with the increasing demand of the quality on packaging containers for food,
pharmaceutical, cosmetic and high-grade daily necessities, the automatic
injection & stretch blow molding technology is adapted to the needs of the
market. By using this technology, the product is finished in one step from
preform injection, forming by stretch & blow, to ejection. The production
is of no flash, no deflating material, avoiding double pollution, and the
products have good quality on appearance, smooth mouth and excellent sealing.
The technology has the advantages of realizing light weight on production
process, with high speed, high efficiency, and energy saving etc..
Working principle
adopting
vertical rotating mechanism, and with four stations equidistributed on the
rotary table, which are injection, temperature adjusting, stretch & blow,
and releasing. Four process of preform injection, temperature adjusting on
preform, forming by stretch & blow, and releasing are finished at the same
time. No additional process needed and one-step injection stretch blow molding
is realized.
Servo motor positioning
system
the
rotary table mechanism adopts servo motor control system with high precision.
Rotary table is sensitive and of accurate positioning.
Energy saving
power system
adopts
energy-saving variable pump or servo motor system and saves the electricity
consumption up to 30%-60%.
Compressor air
system
Recycles
the used high pressure air during bottle blow molding and reduces air
consumption. (Optional)
Standard hot
runner system
No
replacement of hot runner system when mold changing which reduces the mold
cost.
