What is trial mold for aluminum alloy mold?

1. Make the processing operation time longer to stabilize the melt temperature and hydraulic oil temperature.　　2. Adjust the machine conditions according to the size of all finished products that are too large or too small. If the shrinkage rate is too large and the finished product appears to be insufficient, you can also refer to it to increase the gate size. 3. If the size of each cavity is too large or too small, correct it. If the size of the cavity and the door is correct, try to modify the machine conditions, such as the filling rate, the temperature of the mold, and the pressure of each part, and check some molds. Whether the cavity fills the mold slowly. 4. According to the matching situation of the finished product of each mold cavity or the displacement of the mold core, make individual corrections, and it is possible to retry to adjust the mold filling rate and mold temperature to improve its uniformity. 5. Check and modify the failure of the extruder, such as Defects in oil pumps, oil valves, temperature controllers, etc. will cause changes in processing conditions, and even the perfect mold cannot perform well in poorly maintained machines.　　After reviewing all the recorded values, keep a set of samples for proofreading to compare whether the corrected samples are improved.
