General multi-layer co-extruded die in the use of a period of time, the need for replacement or cleaning and maintenance, after all, a long time the friction will have some impact, the multi-layer co-extrusion die cleaning and maintenance should pay attention to the corresponding operation, First multi-layer co-extruded die removed, the following we give you talk about multi-layer co-extrusion die from the demolition to a clear maintenance of a step.
The removal, cleaning, repair and maintenance of the die should be carried out at the designated location, away from the production site, pay attention to clean and with a corrugated board pad, with a small crane, hand hanging, the pulley group chain often Damage to the die. In order to avoid this danger, you can consider the use of hemp rope. The work site should also be equipped with a variety of tools (screwdriver, torque, wrench), soft shovel (bronze, copper, soft lu), cleaning and polishing materials, if possible, there should be a die preheater, which can greatly shorten the replacement mold Head of the time. And the inspection of the heater is also necessary. This preheater should be equipped with a number of heating wires and control systems. At this point it is not necessary to have a separate control of each die heater, but this depends on the size of the die.
If the die needs to be thoroughly cleaned, the main bolt of the die must be released, but not removed, the die is still connected with the extruder, just loosen the flow channel.
Of course, there are generally professional maintenance staff to operate, these are professionally trained, so for the multi-layer co-extrusion die disassembly, cleaning and maintenance do not have to worry about.
