What Are the Advantages of Milk Bottle Blow Molding Machine？

Extrusion Blow Moulding

Extrusion blow moulding is the most common and simplest production method. It is a continuous process that allows manufacturers to produce large quantities of hollow plastic parts quickly and efficiently. It is commonly used to make containers for applications like food packaging, personal care products, and automotive fluids. The process is highly versatile and can produce parts in various materials, including polypropylene and polyvinyl chloride (PVC).

Injection Blow Moulding

Injection Blow moulding begins with a small amount of molten plastic being injected into a mould to form a preform, a tube-like piece of plastic with a hole on one end. The preform is then moved to a blow mould, heated and blown with high-pressure air to expand and shape it. The plastic is then cooled and solidified before being removed from the mould.

A variety of shapes, sizes, and features can be achieved by manufacturers using the flexible process of injection blow moulding. It is frequently used to produce small, precise parts, like pharmaceutical bottles.

Stretch Injection Blow Moulding

Stretch injection blow moulding is a process that is similar to the others. On the other hand, the stretch step in this process is an essential part of the injection stretch blow moulding process because it enables manufacturers to produce parts with complex shapes and features. It also improves the strength and clarity of the finished product by aligning the plastic molecules in a uniform orientation. Although it has a much higher production rate than the other two types of blow moulding, it is significantly more expensive to set up.

Over the years, plastic milk bottles have replaced glass milk bottles to a great extent. After all, besides a lower price, they offer several other advantages when compared to their glass counterparts: they are lighter, they suffer from fewer breakages, and they can come in a wide variety of designs.

The most common material for these products is high-density polyethylene (HDPE) which is food grade and thus, safe for storing perishable goods. However, other materials such as low-density polyethylene (LDPE) and polyester (PET) can also be used. With the use of plastic resins, milk bottles can be round, have a more square or rectangular shape -or even have integral handles if necessary. These bottles are produced by milk bottle blow molding machines that aim for automation by including the necessary auxiliary equipment.

How Are Milk Bottles Produced?

Milk bottles are produced by milk bottle blow molding machines. These are small, continuous type extrusion machines in which an extruder is constantly producing a parison. The parison is captured in a mold. Once the mold closes, air is injected through the top or neck, making the hot plastic material touch the walls of the mold. After the material cools and hardens, the mold is opened to eject the plastic product.

Automation in Milk Bottle Blow Molding Machines

Automation can be very important in manufacturing processes, and, after the effects of the global pandemic, an increased implementation has been observed. The end goal of automation in the context of blow molding manufacturing is to not only reduce the need for manpower, but also to drive higher efficiency by increasing production capacity, reducing costs, or both.

In the case of automatic extrusion blow molding, automation can be achieved by a milk bottle blow molding machine with the following accessories:

• An auto-deflashing unit, which removes the flasher
• A conveyor system, which transports the waste material to the crusher
• A crusher, in charge of material grinding
• Other auxiliary equipment such as a leak tester, depending on the plastic products being produced.

The result is high-quality plastic blow-molded products produced by requiring fewer labor resources or human efforts.

Milk Bottle Extrusion Blow Molding Machines &#; New Versions

Milk bottles are typically produced by small blow molding machines which are suitable for 1L to 5L products. Such plastic milk bottle making machines can be very profitable with features such as single cavities (for low production outputs) or multi-cavities (for higher production outputs in one cycle). Moreover, with a double station machine, production can be increased 1.8 times when compared to single station machines. Another important feature is the parison control which greatly increases the quality and strength of the products and saves material cost by reducing waste. Furthermore, besides producing milk bottles, these versatile machines can also be used to make other products such as pharmaceutical bottles and containers for clean room blow molding.
