Plastic bottles have massively invaded the majority of industries, particularly beverage factories. From storing water and juices to oils and other liquids, PET bottles are the most used packing units in the world today. 

Hence, water bottle blowing machines are highly in demand for beverage storage, packaging and selling. However, there are different machines available with varying capacity.

Hence, buying the right device that matches your industry can be challenging. 

Here are some important things to learn about water bottle blowing machines that will help you make the perfect choice. 

What is a water bottle blowing machine?

As the name suggests, water bottle blowing machine is a device that works by blowing air into a parison, shaping the hollow bottles as it inflates. 

The device can produce large quantities of plastic bottles of various sizes and shapes. 

Overview of the process of producing bottless

• The raw material widely used in bottle production is PET (Polyethylene Terephthalate) that is fed into the water bottle blowing machine. 
• A parison with a conventional downward extrusion is inserted in the mold cavity until the desired length is reached. 
• The neck end catches and holds until the bottom end pinches and the tube closes. 
• A blow-pin is inserted into the neck of the hot parison while low-pressure air of around 25 to 150 psi is forced into a parison to inflate it to the shape of the mold cavity.
• Once the mold sufficiently cools down, you get the finished bottle and excess plastic that is trimmed off from the neck and bottom portions. 

Types of water bottle blowing machines

Water bottle blowing machines can be broadly divided into two categories. 

Fully-Automatic Bottling Machine

In automatic water bottle blowing machines, all bottle production operations are automated. In this process, the operator pours the preform into a special chamber and the machine automatically controls the performing, heating, inflating, and bottle delivery operations. These machines are particularly used in high circulation workshops. 

Semi-Automatic Bottling Machine

The operation process of semi-automatic water bottle blowing machines is similar to the fully-automatic one. But in this model, the preform removal stage is managed by a human operator. 

Technical characteristics of water bottle blowing machines

• The capacity -that means how many bottles it can produce in an hour. 
• The volume of bottles produced according to the given amount of mold and air pressure.  
• The maximum height and width of the bottle it can produce, 
• The diameter of the outlet, compressor pressure, device dimensions and more. 

There are plenty of technical specifications to look for in a water bottle blowing machine. So, it is always recommended that you go for a reputed high-quality brand that will customize the model according to design, shape and inventive ideas best suited for your business.
