theoretical output 3000-4000 bottles per hour. Suitable for 20-2000ml bottles.
ECO-4L 4-cavities linear full-auto stretch blow molding machine, is an economical full-automatic PET bottle blowing machine independently developed by WOTAN Machinery. It is economical, fast and convenient. It can produce all kinds of bottles below 2L, including food packaging bottles, edible oil bottles, soda and mineral water bottles, fruit juice bottles, wine bottles, cosmetics bottles and so on.
1. Upgrade to Servo Motor Drive:
a. Preform Feeding System: servo motor partitioning effectively solves the problem of wear and deformation.
b. Preform Transfer System: preforms horizontal movements are driven by Servo Motor. Make preforms 4pcs as one unit, overall simplified stepping motion, achieve high-speed positioning and smooth motion. To complete one step cycle, the Servo Motor drive gear rotate only one-third of a turn. Speed of preform moving is 2 times of Cylinder Driven way.
2. Mold fixed by drawer design, mold changeover can be easily done in half hour.
3. Efficiency Constant Temperature Oven:
a. Use the most advanced high frequency Infrared Lamp, increase heating efficiency 30%－50%.
b. Each layer of lamp are separately controlled, with assistant ruler on machine.
c. Intelligent temperature control system.
Temperature detector feedback to PLC automatically, PLC makes accurate judgment and then control circulation air in oven. It leads to constant temperature in Oven, free from voltage fluctuations and ambient temperature. It works when large ambient temperature difference (-28~45℃).
d. Preform self-rotation System, ensure every side of every preforms are heated evenly, which ensure quality of blown bottle. (thickness up to 4.5mm)
e. Neck Cooling in Oven.
Preform Necks are cooled by recycling water, which avoid neck deformation
