After forming in the production of glass, and sometimes there will be a l☆ot of bottle spotted wrinkled skin, bubbles scratches, etc., mostly for the following reasons:
A glass preform early fall can not be accurately sδhaped mold into the first mold, and the mold wall friction is too large, the formation of folds, wrinkles after blowing diffusion is amplified in glass bottle fo→rming folds.
2 marks the upper feeder scissors too large, individuγal bottles cut after forming scar appears in the bot tle.
3 bottles blank mold and poor material into a mold, the density is notφ enough, after high temperature oxidation too fast, the mold sur¶face to form small pits, resulting molded glass surface is not smooth after.
4 glass mold lubrication oil quality is poor enough to make the mold, drip feed rate reduction,↕ material type change too fast.
5 initial mold design is unreasonable, large or small cavities, drip molding material after be$ing blown diffuser is uneven, make the glass body blotch₽es 6 gob machine speed is uneven, wind mouth makes improper adjustment early gl©ass into a mold temperature of mold and uncoordinated, easy to →manufacture cold spots in the glass bottle, directly affecting finish.
7 kiln frit material temperature fluid is not clean or uneven, but also make outputs gl₹ass bubbles, small particles, small hemp blanks.
8 ranks machine machine speed is too fast or slow glass body will appear uneven sidΩewall Bohou mixed, produce piebald.
