Understanding the Main Plastic Extrusion Defects: Insights from Boyu Extruder

Are you tired of dealing with pesky defects in plastic extrusion process? Look no further! Whether you’re a seasoned professional or just getting started in the industry, this post is guaranteed to provide you with practical insights and strategies to elevate your extrusion game. So buckle up and get ready to say goodbye to those frustrating flaws – it’s time to master the art of defect solution!

Overview of Boyu Extruder and Plastic Extrusion Defects

Boyu Extruder specializes in providing high-quality extruders that are suitable for a wide range of applications. They have a diverse product line that includes single screw extruders or twin screw extruders. Plastic extrusion is a continuous mass production process. The thermoplastic material (powder, particle or pellet) is uniformly melted and then extruded from the forming die by pressure. Most extrusion steps take place inside the machine. Due to the complexity of processing methods, plastic extrusion will eventually have defects.

Useful Solution to Plastic Extrusion Defects

The first step is to examine the equipment components of the manufacturing process. Examining melt pressure and temperature of barrel and die, power of heater and cooling. Moreover, don’t forget about speed of the screw and the line, the motor load in amps. After that, using the digital temperature sensor and pressure gauge to adjust the temperature and pressure. Adjusting the die setting and increasing rpm back pressure for better mixing play essential role in the whole process. Operators can also alter or replace the screw and install a gear pump between the extruder and the die. The last step is maintaining the speed of the extruder.


Boyu Technology is a professional center with professional staff and teams dedicated to discovering and proposing plastic extrusion problems and making solutions to them. Hope the above useful solutions can help you solve the defects of extrusion equipment.
