Solutions for granulation: how plastic pellets are produced and their applications

In this article, we will discover plastic pellets, which are essential in plastic product manufacturing, and the solutions offered for industrial granulation.

What are plastic granules?

Plastic pellets, also known as plastic granules, represent a crucial raw material for the plastics industry.

These small pellets, resembling grains of rice or little spheres, form the basis for creating various plastic products, including bottles, food containers, electronic components, and more.

What’s about the plastic pellets industrial production?

The production of plastic pellets generally starts with natural or synthetic polymers.

Once obtained, companies use them according to their production needs and the type of products to be manufactured.

One of the advantages of plastic granules is that they offer greater efficiency and flexibility, compared to using raw resins, allowing for the recycling and reuse of unused printed material, with an ecological approach.

Industrial granulation methods

There are several methods for obtaining plastic pellets:

  • Wet granulation

The plastic material is immersed in a specific liquid and then passed through a granulator.

  • Dry granulation

Plastic powder particles undergo high pressures, aggregating to form pellets.

  • Fusion granulation

The process involves mixing powders or other plastic materials with specific substances to create the material from which pellets are derived.

  • Crushing granulation

The use of a mechanical milling system to reduce solid material into pellets of the desired size.

Depending on the chosen process, it is possible to obtain plastic granules of different sizes and properties.

Specifically, however, it should be emphasized that the crushing granulation offers a more sustainable approach, allowing the reuse of waste material.

For example, more of the biggest distributors of machinery for the recovery of residual plastic, like VISMEC granulation and plastic material recovery machinery, promote sustainability in the plastic processing industry with technological production methods, which allow the reuse of waste in the production cycle, contributing to reducing the environmental impact of activities.

H2: Plastic granules real applications for industry

Now that we know how plastic pellets are produced, let’s examine their primary applications in various industrial sectors.

Made from natural raw materials like cellulose and starch, they are used to produce sustainable items.

. Consumer technology products

Devices like smartphones, tablets, and computers contain plastic elements for strength and lightness.

. Automotive sector

Plastic pellets are used in the production of internal and external components of automobiles, such as bumpers, dashboards, and seats.

. Medical sector

Plastic pellets meet requirements for sterility, safety, and durability in the production of medical instruments.

. Electrotechnical sector

Employed in the production of electrical and electronic components such as cables, connectors, and covers.

. Beverage sector

Used for the production of plastic bottles and caps.

So, granulation processes are crucial for companies in the plastic material processing sector, and using efficient and sustainable solutions, like granulation and plastic material recovery machinery, we can promote sustainability.
