The operating procedures of positive and negative pressure plastic suction molding machine are as follows: 1. Before starting, carefully check the power supply, control system and heating system of the positive and negative pressure plastic suction molding machine, mainly to see whether they are normal, add lubricating oil according to the instructions, and whether the buttons are in the correct position, and start the trial run as required; 2. According to the requirements in the instructions for use, correctly install the mold on the positive and negative pressure plastic suction molding machine; 3. When raw materials must be dried, they shall be dried in the oven as required; 4. Check whether the raw materials meet the use requirements of the positive and negative pressure forming machine; 5. Set mold adjustment parameters according to the specific conditions of the mold, including opening, closing, ejection and other parameters to ensure the normal, stable and safe operation of the mold; 6. Preheating the mold can be carried out by setting the required temperature according to the thickness of processing materials; 7. Only when the material temperature and mold temperature reach the preset parameters can the material be loaded. Hard objects and metal objects are strictly prohibited from entering the mold during loading. When placing, carefully check whether there are impurities and sundries in the mold; 8. Adjust the corresponding parameters according to the state of the material. During the pre processing, carefully observe the deformation state of the material, such as whether it is smooth enough and whether the color is uniform, and slowly adjust until it meets the requirements; 9. During the operation, pay attention to the changes of temperature and pressure at any time. In case of abnormal conditions, the machine must be shut down and the power must be turned off. The machine can only be used again after being repaired and recovered by the maintenance personnel.
