Ranks machine play ordinary glass usually use two mold two blowing secondary molding method of
at the beginning of the first mold is shaped die main purpose is to fix the height of the bottle shape of glass material and to a certain degree of cooling
the second mold forming die is to do the glass bottle molding
directly with a mold molding have unsolvable problems
if the material temperature is higher then the bottle after forming in the process of air cooling due to the air temperature is higher than the bottle bottle very much [ Bottle in about 900 degrees to
1000 degrees] Results in a very low air pressure in the bottle will shrink in the bottle to make the bottle out of round
if the material temperature is lower then the bottle blowing process because of the glass material with poor liquidity can make the bottle in thin bottle can withstand the pressure
