Questions You Should Know about Water Bottle Blowing Machine

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. 

In everyday people's lives, the use of plastic bottles for packaging drugs, cosmetics, food, beverages, and many other products has grown so wide and deep. These bottles are produced by a bottle-blowing machine.

In this article, I will be sharing with you a detailed explanation of all there is to bottle blowing machines. We will discuss what they are, their uses, the plastics they work on, and the production process of using bottle-blowing machines for bottle manufacturing.

What is a bottle blowing machine?

A bottle blower is a piece of automated high-speed equipment that produces plastic bottles of different shapes and sizes with high-pressure compressed gas. With this machine, a plastic bottle manufacturer can be able to produce a wide broad range of finished plastic bottle products in varying sizes and shapes.

However, it is important to purchase the bottle-blowing machine from a reliable and reputable manufacturer or supplier that can guarantee you are getting the best out of the use of the machine.

Where is bottle blowing machine used?

Plastic bottles are used to hold liquids and semi-solid products. Therefore, the bottle blower finds applications in industries that produce these products. These industries include;

The beverage industryThe food industryThe cosmetics industryThe pharmaceutical industry

Types of Plastics Used with Bottle Blowing Machine

There are several examples of these different types of plastic options available for use with a bottle blowing machine. Each of these plastics possesses unique properties that make them the correct plastic for a particular product.

1. Polyethylene Terephthalate (PET): Polyethylene terephthalate (PET) is a type of polyester used in the production of plastic bottles.

2. High-Density Polyethylene (HDPE): HDPE is the most commonly used to manufacture bottles for different products that require the safest and most durable plastics.

3. Polycarbonate (PC): PC is a clear and strong plastic that is the perfect choice of plastic for the production of complex-shaped plastic bottles that requires extreme strength.

4. Polypropylene (PP): PP is a popular low-density and extremely stiff plastic that is suitable for bottle production of high-temperature products.

What is the production process of the bottle blowing machine?

The process is divided into four major steps.

1. Pre-heating

In the preheating step, the bottle preform body (inner and outer walls) is heated to a suitable molding temperature. The bottle mouth is cooled during this preform heating.

2. Bottle blowing

This is the stage where the uniformly heated bottle preform is sent to the bottle blow mold to blow the bottle with a high-pressure gas and later allowed to cool.

3. Demoulding

After blowing the bottle, that machine begins to remove the molds.

4. Transmission

The molded bottles are then pulled out or blown out through the conveyor belt. Are you in need of a premium bottle blowing machine?
