Cognac Glass bottle are highly regarded for their exceptional transparency and resistance to corrosion. So it makes them ideal for various applications where chemical interactions do not alter the material properties.
Cognac glass bottle manufacturing
A major manufacturer of heavy glass bottles shares with you Cognac glass bottle. After glass bottle production and forming, sometimes issues such as wrinkles, bubble scratches, etc.,therefore, may occur on the bottle body, mainly due to the following reasons:
1. The glass blank does not accurately enter the primary mold when dropped into the primary mold, causing friction with the mold wall and forming wrinkles. After blowing, the wrinkles spread and form wrinkles on the glass bottle body.
2. The scissors of the feeder are scratched, forming individual scissor scars on the bottle body.
3. The quality of the primary mold and mold material of the glass bottle is poor, the density is insufficient, and oxidation occurs too quickly after heating, forming small pits on the mold surface, so leading to polishing of the glass bottle surface.
4. Poor quality of mold oil will cause insufficient lubrication of the mold, slowing down the descent speed, and material type changes too quickly.
5. The design of the primary mold is unreasonable. The cavity is too small or uneven. After the material is dropped into the mold, it blows up and diffuses unevenly, causing spots on the glass bottle.
6. Uneven machine dripping speed. Inconsistent temperatures of the primary mold and bottle mold are prone to cold spots on the glass bottle body, directly affecting surface smoothness.
7. Unclean glass frit liquid in the kiln or uneven material temperature can also cause bubbles, small particles, and small spots in the produced glass bottles.
8. If the bottle cutting machine speed is too fast or too slow, the glass bottle body will be uneven, with different wall thicknesses, leading to patterns.
