Types of Blow Moulding Machines

A blow moulding machine makes hollow plastic objects by forming a parison and blowing the parison into the shape of a hollow container. The three main types of blow moulding machines are extrusion, injection, and stretch blow moulding machines.

• Extrusion Blow Moulding Machine:

The parison is created through the melting and forcing of plastic through a die. Air is blown through the centre of the cooled part to expand it until it takes on the shape of the cooled mould. The cooled mould can be a two-part blow mould, which then separates to release the final product. This blow moulding machine creates a wide variety of products but is the most common for making products with necks, such as bottles.

• Injection Blow Moulding Machine:

This machine creates the neck and preform separately, with the body of the product formed in the injection mould. The preform can be made in an injection mould, then heated and expanded in an injection-blow mould combination. This allows for greater design and production control, especially for more complex products. This machine is more commonly used for smaller objects.

• Strain Blow Moulding Machine:

• Co-Extrusion Blow Moulding Machine:

This kind of blow moulding involves stretching the parison in order to blow it into the cooled mould. It differs from the more standard method of blowing air. This method improves the distribution of material in the moulded object. It also improves the molecular orientation of the plastic, increasing the object's strength and rigidity. This kind of blow moulding machine is preferred for more robust objects needing greater durability.

A co-extrusion blow moulding machine creates layered products made of more than one kind of plastic. When working with different types of plastics, such as re-cycled polypropylene or softer polyethylene, this machine is useful. It allows the operator to blend various kinds of plastic as needed to create a product with the desired material.

A single-layer product, such as a milk jug, might be made using an extrusion blow moulding machine or any of the stretch-blow moulding machines described above. However, for a product requiring a multi-layer object, such as a car fuel tank, a co-extrusion machine will likely be required to produce the desired object.

Specifications and maintenance of a blow moulding machine

Specifications:

• Machine weight: The weight of the blow molding machine varies depending on the type, model, and capacity of the machine. For example, a small blow molding machine may weigh around 2,000 to 5,000 kg, while bigger machines like the ones used for making plastic barrels or tanks may weigh 10,000 kg or more.
• Machine size: The height, length, and breadth of a blow molding machine also vary according to the type of the machine. The overall machine may have an approximate size of 10m x 4m x 3m.
• Power: The power consumption of blow molding machines again varies according to the type, model, and capacity of the machine. An approximation shows that a small blow molding machine may consume power in the range of 10 to 50 kW, while bigger machines may consume 100 kW or more.
• Pressure: The pressure at which the blow molding machine operates can be anywhere between 5 kg/cm2 to 40 kg/cm2 or even higher in special cases. The operating pressure of the machine also depends on the material being used.

Maintenance:

• Regular cleaning: It is important to keep the blow molding machine properly cleaned on a regular basis. Dust, debris and other contaminants must be removed from the machine to keep it in a proper working condition and to prevent any damage.
