Eternal blister machine: blister machine blister molding bad cause analysis and method
As we all know, there are many reasons for the bad plastic forming of the blister machine. Today, Eternal Sheng Xiaobian will introduce the analysis and method of the bad plastic forming of the blister machine.
Vacuum eye:
Reason: Method A: Generally, the standard drill bit is 0.5-0.8mm. When punching the plastic suction die, pay attention to distinguish the bottom punching method (generally, the punching is at the R position of the die). Method B: After repairing with putty, drill again with a 0.5mm steel needle.
Reason: vacuum pressure relief too fast method: appropriate adjustment of pressure relief speed
Reason: the sheet temperature is too high method: reduce the temperature or shorten the heating time
Surface hydrological aspects:
Reason: bad method of vacuuming: check whether the vacuuming system is leaking and whether the vacuum hole is blocked.
Reason: The air pressure is not enough. Method: Check whether the air pressure is normal, the normal is 0.7mpa
Reason: mold typesetting size is too dense method: in the blister industry, typesetting size is arranged with a ratio of 1:1, except for special circumstances.
Reason: improper die arrangement position method: check the suction mark position and re-arrange the die
Reason: improper matching time between upper and lower methods: adjust the time between upper and lower molds and vacuuming
Reason: improper matching of the upper die. Method: Observe the position of the indentation caused by the upper die when it is pressed down, and adjust the angular position of the upper die appropriately.
Reason: vacuum too slow method: speed up the vacuum time
Reason: chassis is too high method: appropriate adjustment of the bottom mold height
