Brief summary

In the world of plastic extrusion, as in any industrial process, problems can occur. In this article, we will look at the most common problems and provide detailed, practical solutions to guarantee continuity in your manufacturing and product quality.

Five common problems in the plastic extrusion process

During plastic extrusion and its various applications, it is possible to encounter anomalies that may influence the quality of the product. Careful analysis of these possibilities will not only highlight the extraordinary nature of the extrusion process, but will be able to offer practical solutions to deal with any problem efficiently.

Tackling these problems with targeted solutions requires a combination of careful planning, constant monitoring, and the adoption of cutting-edge technologies. Implementing these solutions not only resolves specific problems, but also helps improve the overall efficiency of the extrusion process in its various applications.

Let’s focus our attention on the five most common problems that can occur. All these obstacles require a targeted approach and specific solutions to guarantee smooth production and the manufacturing of premium plastic products.


1) Extruder stops working: if the extruder stops working, this common problem can be caused by impurities or unmelted material building up, blocking the regular flow of the plastic material through the extruder.

  • Solution: to keep your extruder running smoothly, it is vital to carry out regular preventative maintenance. Inspecting and cleaning the extruder to remove impurities or unmelted material in a timely manner can help reduce the risk of the extruder stopping. The use of suitable filters and cooling devices may help prevent the build-up of debris.


2) Temperature variations: fluctuations in temperature may influence the viscosity of the plastic material, leading to quality issues in the end product, such as irregularities in its shape or mechanical characteristics.

  • Solution: carefully checking the temperature is key to managing fluctuations. The use of advanced thermal sensors and automatic control systems allows a constant temperature to be maintained throughout the extrusion process. The thermal insulation of critical parts may also help reduce the effect of external variations.


3) Adhesion problems: insufficient adhesion between the layers of plastic material may occur due to problems linked to temperature, pressure, or the composition of the material itself, compromising the quality of the end product.

  • Solution: to improve adhesion between the layers of plastic material it is vital to optimize the temperature and pressure parameters. Carefully testing and adjusting these parameters based on the specific composition of the plastic material used will help guarantee proper adhesion.


4) Trapped air: the build-up of air during the extrusion process can cause the formation of bubbles in the plastic material, leading to surface defects and reducing the resistance of the finished product.

  • Solution: minimizing the build-up of air requires implementing effective degassing devices. Strategically placed degassing systems throughout the extrusion process helps eliminate undesirable air bubbles. Checking pressure during the process also helps stop air getting in.


5) Misshapen products: misshapen products may occur due to irregular or too rapid cooling, compromising the shape and quality of the extruded plastic product.

  • Solution: carefully controlling the cooling speed is vital to preventing unwanted misshapen products. Implementing consistent and carefully controlled cooling systems, as well as a suitable post-extrusion cooling process, can help maintain the required shape of the plastic product.
