- Insufficient accuracy during the entry of the glass material blank into the initial mold can lead to friction with the mold wall, resulting in creases. These creases expand during positive blowing, forming wrinkles on the bottle body.
- Large scissor marks on the feeder can cause scarring on the bottle body after molding in some glass bottles.
- Poor quality initial mold and mold forming materials can result in insufficient density, rapid oxidation at high temperatures, and the formation of small pits on the mold surface, leading to an uneven and unsmooth surface on the glass bottle after molding.
- Low-quality mold oil can lead to inadequate lubrication of the mold, decreased dropping speed, and rapid changes in material type.
- Unreasonable design of the initial mold, such as having a cavity that is too large or too small, can result in uneven material diffusion when it drips into the mold, causing spots on the glass bottle body.
- Inconsistent dropping speed and improper adjustment of the air nozzle can lead to temperature inconsistencies between the initial mold and the mold, creating cold spots on the bottle body that affect smoothness.
- Unclean glass liquid in the kiln or non-uniform material temperature can result in bubbles, small particles, and defects in the glass bottle, such as small hemp billets.
- Inappropriate machine speed, whether too fast or too slow, can lead to uneven glass bottle bodies, varying wall thicknesses, and the presence of spots.
