Gun-Shaped High Borosilicate Spirit Bottle

High - purity borosilicate glass tubes are precisely cut by automated machinery. These systems slice tubes to exact lengths based on bottle design requirements. Accurate slicing is fundamental-any error could cause structural weaknesses or visual inconsistencies in subsequent processes.

The cut tubes then undergo high - temperature base sealing. One end of each tube is exposed to extreme heat, melted, and sealed to form the bottle's base. This closed structure stabilizes the glass during blow molding. Temperature control is crucial: insufficient heat results in incomplete seals, while excessive heat causes defects like bubbles or warping.

Sealed tubes are then shaped in tailored molds. Reheated until molten, the glass is formed by controlled air pressure or mechanical force inside custom molds. This stage defines the bottle's unique shape, whether classic curves or brand - specific artistic designs. Strict control over temperature, pressure, and mold alignment ensures intricate details (e.g., embossed logos, curved edges) and consistent wall thickness-directly impacting strength and visual appeal.

Finally, stress - alleviating annealing enhances durability. Formed bottles are placed in an annealing furnace for gradient thermal treatment: heated to a set temperature, held to balance internal stresses, and cooled slowly. This eliminates residual thermal stress, improving mechanical strength and resistance to temperature changes. Without proper annealing, the glass is likely to crack during handling or use.
