What causes the poor smoothness of glassware?

Crystal is the main material for glassware production because it has good transparency and is clean and bright. However, in the production process of glass product manufacturers, if the whole process is not rigorous or the quality of the mold is poor, it will lead to defects such as spots, wrinkles, bubble scratches and so on. So, what is the reason for the poor smoothness of the glass?

The quality of the initial mold and the finished mold is poor.

Sometimes when a glassware manufacturer produces glasses, the initial glass of the mold and forming material is poor, the density is not enough, and after the oxidation is too fast and the temperature rises, the mold will form a small pit on the surface, and it is easy to cause the glass surface to be uneven after the formation. Therefore, glassware manufacturers remind everyone that when choosing a mold, you must pay attention to the initial mold and mold material to ensure that there will be no problems with the smoothness of glass molding.

Friction with mold walls.

In the production process of glassware, sometimes when the glass blank falls into the initial mold, it cannot accurately enter the initial mold, and it will rub against the mold wall and form wrinkles. During the blow molding process, the surface wrinkles will spread, which will easily cause the bottle body to wrinkle and seriously affect its finish.

The initial design of the mold is unreasonable.

Sometimes when glass manufacturers produce glasses, due to the unreasonable initial mold design, there will be problems in use. If the mold cavity is too small or too small, problems will occur. In this way, the material falls into the forming mold and blows unevenly, resulting in speckles on the glass body.

The velocity of the droplets is not uniform.

Sometimes when glass manufacturers produce glass, the machine speed is uneven or the nozzle is adjusted improperly, so that the initial temperature is incompatible with the temperature of the glass, which will lead to cold spots on the bottle, which will directly affect the finish.
