Blowing machine bottle bottom concave present causes and solutions
1、Bottom of the bottle is not enough base material Solution: Reduce the heating temperature of the bottom of the bottle 2、Bottom of the bottle heating temperature is too high Solution: adjust the bottle bottom heating temperature to the right temperature, different manufacturers have slightly different temperature adjustment, adjust the temperature can consult the bottle blowing machine manufacturers. 3、Insufficient pre-blowing gas Solution: extend the pre-blowing time 4、Insufficient high pressure Solution: Increase the amount of high pressure blowing
