When the aluminum profile extrusion machine cannot extrude the profile under the maximum working pressure, commonly known as stuffy car, there are many reasons for the stuffy car of the extrusion machine, such as: low temperature of aluminum rod, low temperature of extrusion cylinder, low extrusion speed , The mold temperature is low. If any of the above situations cause the stuffy car, then we need to check the temperature setting of the extruder. If the temperature setting is too high or too low, it will not work. To effectively solve this problem, It must be operated by professionals in accordance with the instructions of the extruder to avoid the recurrence of the problem.
