What is a glass mold?
The molds of molten glass are called glass molds.The most representative and most used is the glass mold of the bottle.Because the diameter of the bottle is smaller than the diameter of the carcass, the mold is often made to be articulated in order to facilitate the release of the parts.
Molding is the molten glass that enters the mold with compressed air pressure.In order to prevent the wall thickness from blowing, the process of two steps of rough molding and fine molding can be used.The blank is made of rough mould, and the mold is made into finished product.
The molding method has manual molding, semi-automatic forming and automatic forming.Most of the production is fully automatic molding with automatic bottling machine.
In the process of molding, the mold is in contact with the molten glass of high temperature, and the mold temperature is also increased. Therefore, it is necessary to consider the thermal twin of the mold.The mould material is generally made of structural steel, and the surface hardening treatment can be done easily.
