List Of Factors Influencing The Forming Of Glass Wine Bottles

Everyone knows that glass wine bottles have high production requirements, and even slight defects can affect quality and aesthetics, thereby affecting sales. Therefore, glass wine bottle manufacturers will consider many factors when producing wine bottles, such as what factors cause or damage the uneven smoothness of the bottle body. Based on the problem, solutions can be proposed to make good products to give back to customers. So, what are the factors that cause poor quality in the production and molding of glass wine bottles? Let's learn together now.

When the glass blank falls into the initial mold, it cannot accurately enter the initial mold, and there is excessive friction with the mold wall, forming wrinkles. After blowing air, the wrinkles diffuse and enlarge, forming wrinkles on the glass bottle body.

2. The scissor marks on the upper feeding machine are too large, and some glass bottles have scissor marks on the bottle body after forming.

3. The initial mold and molding material of the glass bottle are poor, with insufficient density. After high temperature, it oxidizes too quickly, forming small pits on the surface of the mold, resulting in an unclean surface of the glass wine bottle after molding.

4. Poor quality of glass bottle mold oil can lead to insufficient lubrication of the mold, reduced dripping speed of lubricating oil, and rapid change of material type. The initial mold design is unreasonable, with large or small mold cavities. After the material drips into the forming mold, it spreads unevenly during blowing, which can cause spots on the glass bottle body.

6. Uneven material dripping speed of the machine and improper adjustment of the air nozzle can cause the initial and molding temperatures of the glass bottle to be uncoordinated, which can easily create cold spots on the glass bottle body and directly affect the smoothness.

7. Unclean glass liquid or uneven material temperature inside the kiln can also cause bubbles, small particles, and small hemp billets to appear in the produced glass bottles. If the speed of the row and column machine is too fast or too slow, uneven glass bottle body and uneven bottle wall thickness will occur, resulting in spots.
