Changshu smoothly for plastic products factory talk about plastic extruder operation at nine o 'clock

Plastic pipe production line equipment control system, and then through the extruder, head, finalize the design the cooling system, tractor, cutting equipment and material composition. The plastic extruder extrusion principle is to use with slant threaded screw rotation in the heating cylinder, will be sent in the hopper plastic extrusion forward, make plastic heat gradually, uniform plasticizing plastic extrusion, through the nose and molding. Changshu well below da plastic products factory talk about plastic extrusion machine out nine matters needing attention in the process of actual operation:



1, to check whether the good heating circle is in good condition, before starting the thermocouple is good, temperature measurement is accurate.



2, start going to stay when heating temperature reaches the set of process temperature and holding time to start. In case the motor, such as screw parts damaged.



3, the host must run for several minutes at low speed when starting, put out all remaining row of melting in the barrel, waiting for the melt pressure and the host current stable rear can speed up, so as to avoid spray materials will hurt people.



4, in the operation of the equipment to observe parameters such as temperature, current, the melt pressure. And watch the heat situation of motor, reducer, with exception to timely find out the reason and exclusion.



5, heating time, depending on the size of the nose, the nose of the 63 machine heating time not less than 3 hours, 250 head is not less than 6 hours, 450 head heating time not less than eight hours.



6, mold choice: you select the corresponding mold according to the product specification, if improper mold choice will bring difficulties to production.



7, the protection of the mold, mold quality determines the quality of the product, the mould material for steel, commonly do chrome plated surface. In the process of dismantling and handling must protect, not a scratch and collision, etc. Mould generally cannot be placed directly on the ground, should be put on the rubber boards or advisable. Replacing the mould can't knocked with hard tool.



8, the adjustment of the concentricity of mandrel mouth: the mouth of the solid wall pipe production line follow the regulation of mandrel & other; Loose thin top thick & throughout; The principle. Is the interval of the direction of the small screw loosening, tighten the large gap in the direction of the screw.



9, heating circle of protection: generally speaking, the use of heating coil and a long life, often is in the process of remove damaged, heating circle take extra care when removing process.
