The extrusion process is an important step in a pellet extruder, but sometimes you will encounter the problem of plastic long strip breakage. This not only affects production efficiency but also reduces the quality of recycled plastic pellets. Today, we will explore the causes of the waste plastic extrusion machine broken bar problem and provide solutions to ensure the stability of the plastic film extrusion process.
Temperature of pellet extruder
Temperature control of the pellet extruder is a critical part of the extrusion process. Improper temperature setting or unstable temperature can cause non-uniformity in the melting state of the plastic, thus triggering long strip breakage. Therefore, ensuring stable temperatures in the heating zone and die head of the waste plastic extrusion machine is an important measure to avoid bar breakage problems.
Plastic film extrusion screw and die head
The screw and die head design of the pellet extruder is also a key factor in the bar breakage problem. Poor screw mixing effect or unreasonable die head design may lead to plastic strip breakage. Therefore, ensuring that the plastic film extrusion screw is well-mixed and the die head is well-designed is a critical step in improving the stability of the extrusion process.
Pellet extruder extrusion speed
Extrusion speed is the rate at which plastic is extruded from the inside of the waste plastic extrusion machine. Excessive extrusion speeds may cause the plastic to melt sufficiently or cool insufficiently to cause long strip breaks. Properly controlling the extrusion speed of the pellet extruder and maintaining a steady production rate can help avoid long bar breaks.
Waste plastic extrusion machine molds
Wear and tear of the mold can also cause long bars to break. Prolonged use may make the surface of the die uneven or damaged, which in turn affects the stability of the pellet extruder extrusion process. Regular inspection and maintenance of the mold to keep their surfaces flat and smooth. It is essential to ensure the stability of the waste plastic extrusion machine extrusion process and the quality of the recycled plastic pellets. Through die maintenance, the plastic film extrusion can operate consistently and stably and produce high-quality recycled plastic pellets.
All of the above methods are key measures to ensure a stable and efficient pellet extruder extrusion process. By continuously improving and optimizing the process, the waste plastic extrusion machine extrusion process will be smoother.
