Analysis of quality problems in cosmetic glass bottle technology

There are some technical problems in the molding process of cosmetic glass bottles. The analysis is as follows:

 1. The falling time of the first glass blank can not be accurately shaped into the mold blank mold, the friction of the mold wall is too large, the formation of creases, and the expansion of the blow, the wrinkles that are formed in the glass bottle wrinkle.

 2. The scissors scars of the feeder on the upper structure are too large, and individual different bottle designs can appear on the bottle body through the scissors scars after molding.

 3. The material of the first mold and the molding glass is poor, the density is insufficient, and the mold temperature is excessively oxidized, thereby forming fine pits on the surface of the mold temperature, so that the molding surface of the rear glass is not smooth.

 4. The quality of the mold The poor oil of the glass mold will lead to an insufficiently lubricated system, which can reduce the drip rate and rapidly change the development of the material type.

 5. The design structure of the initial mold is unreasonable, the mold cavity is large or small, and after the material is dropped into the molding process mold, it is blown and spreads unevenly, which will make a glass bottle body 6. The machine has uneven dripping speed and improper adjustment and management of the air nozzle. It will make the initial mold of the glass bottle uncoordinated with the working temperature environment of the mold, and it is easy to cause cold spots in the research of the glass bottle body, which directly affects the smoothness.

The glass liquid in the melting furnace is not clean or the glass temperature is not uniform, which can also produce glass bubbles, small particles, and small hemp billets.

 7. The glass body with slower or faster speed will appear uneven, and the changing sidewall thickness will cause spots
