What is an Extruder and Does Your Company Need One?

Extrusion enables the changing of the shapes of materials. This process transforms plastics into pellets and tubes. Because of this, many industries use extruders because of the vast advantages they could provide. Generally, extrusion makes production and manufacturing faster because of its continuous operation. Apart from it, it typically offers a better output as to quality and quantity.


Extrusion is standard in the industries of production, engineering, and agriculture. If you’re working in any of these industries, you may want to know more about this machine. Suppose you want to learn everything about extruders, here’s an article that could guide you. So, read on!

What Is An Extruder

Extrusion is a go-to process in manufacturing tubes, pipes, and ceramic products. For example, a round plastic item is pushed into a die or three-sided mold with prefab shape and form. In this process, the product needs a reliable extruder. Generally, it heats the materials, so the intended structure and shape are achieved.

Benefits Of Extrusion

Apart from making the production quicker, the extruders have benefits that make them essential. Here are some of them:

  • Low Cost: Generally, extruders have lower costs than other machines used to shape up or mold. In addition, the fast-paced production enables high-volume production, reaching the target number of products in a shorter time. If you’re planning to buy an extruder, you may look for used extruders for sale as they could maximize your expenses.
  • Flexibility To The Type Of Material: Many extruders could work on plastics, metals, copper, aluminum, steel, and other basic manufacturing materials. In addition, the machines could process different sizes of materials.
  • Flexibility To The Type Of Operation: Since many industries could use extruders in their operations, they have enough flexibility to manufacture products.
  • Applicability To Post-Extrusion Changes: Workers could easily alter the forms or shapes of the materials if they’re still in a heated condition.

Industries Utilizing Extruders

Almost all industries employ extrusion as a process. In many cases, businesses manufacturing products in containers use extruders. To have more ideas, you could dive into the following and see if your business would be productive with an extruder:

  • Food Industry: Tetra packs and plastic cups are some of the products that may have undergone extruders. In many situations, extrusions are applied before or after vacuum sealing to ensure the product’s quality.
  • Pharmaceuticals: Some pharmaceutical companies use extruders for chemical or medical containers, such as tanks, plastic bottles, and ampules.
  • Engineering: Many construction materials are made through extruders. In many cases, tubes, cylinders, and cans are molded from different materials. These include metals, aluminum, and plastics. Furthermore, extruders also help in the production of wires and cables.

Apart from the businesses mentioned above, many workers also use extruders in manufacturing sieves, hydrogels, rods, and other products that need form and size changes. Yet, before buying an extruder, you, first, have to know what to consider before jumping into that decision.

What To Consider Before Buying An Extruder

Purchasing an extruder may be challenging, especially if it’s your first time doing it. To help you select which would work for you, consider assessing your needs first. What type of business do you have? Are you trying to manufacture plastic containers? Are you planning to produce PVC pipes? To help you decide, here are some points you may look into:

1. Cost-Effectiveness

Generally, efficient extruders are in charge of the manufacturing of high-quality products. More than the speed of production, you may need to look into the material’s durability. Many times, it’d tell whether or not the processed products would extend their longevity. For example, a well-processed bottle may hold a liquid product efficiently by being puncture-resistant and durable at the same time.

2. Work Efficiency

To ensure cost-effectiveness, you may need to check the extruder’s capacity to hold, mold, push, and heat materials. This will also cover the machine’s ability to do the processes efficiently and consistently. For this purpose, you may read about product reviews and customer feedback that generally tell about authentic assessment.

3. Adaptability

Extruders need to be adaptive to any product type as to material, thickness, and shape. In addition, they may need to fit the die that shapes up the blank material. Furthermore, the machine needs to have a considerable length tolerance to adjust to the sudden shrinkage or deformation of materials, especially plastics.

4. User-Friendliness

Extrusion is one complex process. It could be dangerous when the occupational safety hazards are neglected. To ensure that you’d buy a user-friendly machine, look into the extruder’s controls or panel. If you could easily understand how the buttons and panels work, the machine is more likely user-friendly. User-friendliness is also a factor in how extruders could be free from hazards and accidents, especially in construction industries.

5. Heating Or Freezing Capacity

Commonly, extruders have heating and freezing functions. Each of these tasks helps in completing extrusion. In choosing an extruder, you may check the accuracy of each process. In addition, the functions should be reliable enough to allow flexible, adaptive extrusion design and profile to any product.

6. Features And Functions

Apart from the traditional pushing, you may need to see whether the extruder offers the basic or advanced functions in extrusion. For that purpose, you may look into what the machine could do to a melt. Could it alter the material chemically? Could it be mixed with another blank material? Reading the extruder’s specs, manual, and writeups about it could help you know more about it quickly.

Wrapping Up

Generally, products that come from molds or hollow bars use an extruder. In layman’s terms, extruders are machines that heat or freeze products. This way, materials could be melted and softened up, enough to pass through an extrusion and have the intended shape before picking the extruder that’d suit your needs.

You may check back the insights you’ve gotten from this article. By doing so, you may revisit what extruders are and when you need them. If you own a business that’d need reshaping and reforming of materials, such as plastics and metals, you may want to own one. And, before you pay for one, you better know what to consider.
