Fully automatic 4 cavity PET bottle blowing machine

Fully automatic 4 cavity PET bottle blowing machine

This linear bottle blowing machines are used in the production of PET water bottles, hot filling bottles, carbonated beverage bottles, edible oil bottles, and pesticide bottles.linear bottle blowing machine stretches preforms by using a servo motor-controlled stretch rod. The advantage is that it can be stretched in sections,and positioning of the preform is at first in order to ensure the verticality of the preforms during stretching, then secondary stretching.Ensure the uniformity and consistency of each preform stretching.At the same time,bottle blowing machine has a fast stretching speed and precise position.


A. Stable performance with advanced PLC.
B. Conveying preforms automatically with conveyor.
C. Strong penetrability and good and swift distribution of the heat by letting the bottles rotate by itself and revolute in the rails simultaneously in the infrared preheater.
D. High adjustability to enable the preheater to preheat preforms in shapes by adjusting the light tube and the length of the reflecting board in the preheating area, and eternal temperature in the preheater with an automatic thermostatic apparatus.
E. High safeties with security automatic-locking apparatus in each mechanical action, which will make the procedures turn into a state of safety in case of a breakdown in certain procedure.
F.No contamination and low noise with the air cylinder to drive the action instead of the oil pump.
G. Satisfaction with different atmospheric pressure for blowing and mechanical action by dividing the blowing and action into three parts in the air pressure diagram of the machine.
H. Strong clamping force with high pressure and double crank links to lock the mold.
I. Two ways of operating: automatic and manual.
J. Safe, reliable, and unique design of the position of valve to make the air pressure diagram of the machine easier to understand.
K. Low cost, high efficiency, easy operation, easy maintenance, etc, with automatic technological process.
L. Contamination is avoided for the bottle body.
M. Ideal effect of the chilling with the chilling system.
N. Easy installation and starting
O. Low rejection rate: less than 0.3percent.
