Operating Instructions for Rubber Extruders and Winter-Season Operating Precautions
Time：
2017-12-09
When starting up a rubber extruder, do not feed material immediately. First, heat the barrel and screw to the appropriate temperature before beginning feeding. At startup, the machine body is still at a low temperature and does not generate its own heat; introducing rubber into the barrel under these conditions increases the load on the screw. Unplasticized rubber can cause the screw to seize within the barrel, and as the motor attempts to turn it, this may snap the screw or damage the gearbox. In winter, when ambient temperatures are low, be sure to drain all water from the mold‑temperature controller after shutdown to prevent freezing that could rupture the hoses and the unit itself. During the winter, chillers are typically used in conjunction with antifreeze solutions.
When starting up a rubber extruder, do not feed material immediately. Instead, first heat the barrel and screw to the appropriate temperature before beginning feeding. This is because, at startup, the machine body is still at a low temperature and does not generate sufficient heat on its own; moreover, rubber introduced into the extruder while it is cold can lead to undesirable processing conditions.
During operation, the load on the barrel increases; unvulcanized rubber can cause the screw to seize within the barrel, and when the motor attempts to rotate the screw, it may either snap the screw or damage the gearbox.
In winter, when temperatures are low, be sure to drain all water from the mold temperature controller before shutting down the rubber extruder to prevent the pipes and the controller from freezing in the cold nighttime conditions. During the winter, a chiller is used in conjunction with antifreeze to simulate freezing conditions.
When operating the machine, do not insert any part of your body into the rotating feed opening, and do not wear gloves while feeding material. In some cases, gloves may become caught in the screw or the barrel during rubber feeding.
