Different bottles will be used for different kind of liquid.Generally, we have 3 kinds of different drinks bottles.
1. Pure water/non carbonated drinks bottles.
2. Hot juice/drinks
3. Carbonated water/drinks bottles.
Introduction on different bottles:
1. Pure water bottles:
The bottom part of the pure water bottle is flat. Because there is no gas pressure inside the bottles, then the bottles structure can be more simple and no need to take the gas pressure.
In the same blow molding machine, this kind of pure water bottle making will be fast than same volume carbonated drinks bottles.
2. Hot juice bottles:
To make sure the bottle will not be shrunk during the filling process (around 85 degrees), we will need use this kind of white neck preforms to make the hot juice bottles.
We call it hot-resistance preform. The bottles made from these kinds of preforms will not be shrunk within high temperature juice.
The blowing process is slower too. Speed is only around 50% of the pure water bottle blowing.
3. Carbonated drinks bottles
Carbonated bottle use the same clear neck preform as the pure water bottles do.
The different is on the bottom.
The concave-convex part on the bottom make sure the bottle structure can take the pressure from the drinks.
Because this kind of bottom structure is stronger than flat bottom and it can hold the pressure inside without form-changing.
How to get correct mold and molding machine:
You will have to make clear answers for the following questions:
1. What kind of bottles do you need to make?
2. What size bottles do you need to make?
3. How many pcs per hour do you need to make?
