In order to ensure the injection molding capacity of the plastic processing equipment<\/a><\/strong>, everyone will go through a link before using the equipment, that is, the adjustment of the plastic processing equipment. We must not underestimate the adjustment work, because we found that some users ended the adjustment work hastily in order to use the plastic processing equipment as soon as possible. We should know that the adjustment work has a lot of benefits for the equipment.<\/p>\n\n\n\n

Injection molding of plastic processing equipment is an engineering technology, which involves the transformation of plastics into useful products that can maintain the original performance. The important process conditions of injection molding are the temperature, pressure and corresponding action time that affect the plasticization flow and cooling.<\/p>\n\n\n\n

General plastic processing equipment can be adjusted according to the following procedures:<\/p>\n\n\n\n

\u25b6 According to the temperature range provided by the raw material supplier, adjust the barrel temperature to the middle of the range and adjust the mold temperature.<\/p>\n\n\n\n

Estimate the required injection volume, adjust the plastic processing equipment to two-thirds of the estimated large injection volume, adjust the reverse cable (glue extraction) stroke, estimate and adjust the secondary injection time, and adjust the secondary injection pressure to zero.<\/p>\n\n\n\n

\u25b6 Preliminarily adjust the primary injection pressure to half (50%) of the limit of plastic processing equipment; Adjust the injection speed to high, estimate and adjust the cooling time required, adjust the back pressure to 3.5bar, remove the degraded resin in the barrel, and adopt the semi-automatic injection mode; Start the injection molding procedure and observe the action of the screw.<\/p>\n\n\n\n

\u25b6 The injection speed and pressure need to be adjusted properly. To shorten the filling time, the injection pressure can be increased. As mentioned earlier, there will be a process before full filling, and the final filling pressure can be adjusted to 100% of the primary injection pressure. The pressure of plastic processing equipment should be adjusted high enough so that the large speed that can be achieved is not limited by the set pressure. If there is overflow, the speed can be reduced.<\/p>\n\n\n\n

\u25b6 After each cycle of observation, adjust the injection amount and conversion point and set the program so that 95-98% mold filling can be obtained according to the injection weight at the first stage of injection molding.<\/p>\n\n\n\n

\u25b6 When the injection volume, conversion point, injection speed and pressure of the first stage injection molding are adjusted properly, the adjustment procedure of the pressure holding pressure of the second stage can be carried out.<\/p>\n\n\n\n

\u25b6 Adjust the holding pressure properly as required, but do not overfill the mold cavity.<\/p>\n\n\n\n

\u25b6 Adjust the screw speed of plastic processing equipment to ensure that the glue melting has been completed just before the cycle is completed, and the injection cycle is not limited.<\/p>\n\n\n\n
