Stable operation and extended life of extruders: Operating procedures and maintenance guidelines

In order to ensure the stable operation of the extruder and extend its service life, the operator needs to adopt a series of operating procedures. First, before each start of work, the operator needs to use the turning crank to manually turn the motor. This step is essential because it checks whether the motor can be turned easily and with less effort. If the rotation is not smooth or any resistance is felt, it may mean that some parts inside the machine are not fully warmed up. In this case, the operator needs to continue to hold heat at the process temperature for 3 to 5 minutes in order to give the parts inside the machine enough time to warm up. This ensures that the parts are adequately preheated, thus reducing the risk of overload due to sudden start-up.

Once the warm-up is complete, the operator can begin the formal workflow. First, the screw rotates at a low speed while a small amount of material is added. This slow start mode helps to ensure a smooth start of the machine and avoid excessive impact on the equipment. As the material is gradually extruded, the speed of the screw will gradually increase to the value required by the process. This control helps to ensure consistent quality and performance of the products produced.

When the work is completed and downtime is required, Zones 1 and 2 need to be forced to cool to room temperature. This is because certain materials may cure at high temperatures, leading to clogging or damage to the equipment. If it is kept warm or idled for a long time, it will cause the machine to overheat, which will damage the internal parts and affect the life of the equipment. Therefore, after each work is completed, it must be cooled in time.

In order to ensure the normal operation of the equipment and extend the service life, the operator must strictly follow these operating procedures. Only through scientific and reasonable operation and maintenance can we ensure the stable operation of the extruder and bring continuous economic benefits to the enterprise. In addition, regular maintenance and inspection of the equipment is also very important to ensure that it is always in good working condition.
