When you decide to make water bottle
project, do you think that buy one suitable set of injection molding machine is
ok?
In fact, a PET
bottle perform production line is made up by several device. PET injection molding machine is the main
equipment, the line also need necessary auxiliary machine. Now we share below
points for you to select PET production line machine.
PET is a special material, it’s generally
used as raw materials for plastic beverages bottled. But PET is different from
normal PP material. PET have large specific heat capacity, so it required high
molding temperature. In order to make the temperature easier to reach, we will dehumidifier
and dry the original material before injection.

1.
PET dehumidifier machine
In order to dry the material fully,
material dehumidifier is important step before production.If the PET material is not completely
dried, the surface of bottle preform will looks blurry. So dehumidifier machine
is a vital equipment for PET bottle perform production line.
In general, most PET perform mold is
multi-cavity. Before the machine model choice, we should pay attention to the
actual weight of bottle perform and hourly consumption.
Total hourly consumption= (3600/cycle
time)* perform weight*mold cavity
For better stability, the theoretical dehumidifier
weight of machines should be 1.35 times at least of actual consumption.
2.
Air Dryer
Hot air is used to dry the wet materials
that due to moisture absorption during packaging, transportation and recycling
cycles. The air dryer model should depend on the injection machine tonnage and
hourly consumption. Material loading capacity of dryer equipment also need
bigger than the hourly consumption.
3.
Auto loader
When the PET material finished dehumidifier
and dry, the auto loader will put it on injection machine for manufacturing. But
the points is very important, the pipe of the loader should be high temperature
resistance. Ordinary pipes will melt and affect daily production.
4.
Water chiller
Typically, PET bottle perform mold is made
by through-hardened steel S136. Once the mold put on machine for mass
production, you must to connect water pipe for cooling, otherwise the mold
steel is easy to broken.
Water chiller play the role of cooling and shorten
the cycle time. The model of chiller should matched with PET injection molding
machine tonnage, you could ask the supplier for recommend.
In conclusion, the above four kinds of auxiliary equipment are necessary for PET bottle perform project. Others machine such as
mixer, crush, air compress is decided by your demand. If you are not experienced,
you can ask the supplier for help and give you suggestion of PET perform device.
Sino Holdings Group is Chinese famous plastic
injection molding machine manufacturer. We can offer customer PET
perform production line turnkey solution, including injection machine and
auxiliary equipment. Please contact us if you are interested.
