4 key points to pay attention to when extruding rubber injection molding machine

1.Before the rubber material is extruded, no employees are allowed to operate in front of the mold.

2. The rubber injection machine is started at low speed, idling, and check whether the screw is abnormal and the motor current, etc. The operating instrument is overloaded and the pressure gauge is normal (the idle time of the rubber injection machine should not be too long, the shorter the better, to prevent the friction between the screw and the screw and the friction generated by the barrel, scratching the barrel or screw, and the screw running time should not be More than three minutes.)

3. Start the operation and slowly add a small amount of rubber material gradually. When the rubber is squeezed into the mold, the screw speed can reach the normal operating speed, and then the batch can be fed.

4. After the machine extrudes the rubber material, the extrudate should be slowly introduced into the cooling traction equipment, and the equipment should be opened in advance.

Our above four points are the key things to pay attention to when extruding the rubber press

Note: Please do not drive a cold car, because it is not "hot" during extrusion (that is, the rubber material in the extruder barrel has not fully reached the specified temperature, and the viscosity of the rubber material is very high), and then drive it, especially Old-fashioned squeezing may damage the screws. New equipment is usually equipped with torque overload protection when extruding. A reliable and most effective method is to turn the connecting part three times by hand when the temperature rises to the required temperature before driving. After smooth rotation, you can open the third circle on the right. If you can't turn it smoothly, you just can't open it.
