After the BPA Free Clear Borosilicate Glass Water Bottle is produced and formed, sometimes the bottle body will have many spots of wrinkles, bubble scratches, etc., which are mostly caused by the following reasons:

1. When the BPA Free Clear Borosilicate Glass Water Bottle blank falls into the preliminary mold, it cannot accurately enter the preliminary mold, and it rubs excessively with the mold wall to form creases. After positive air blowing, the creases spread and enlarge, forming creases on the glass bottle body. .

　　2. The scissors marks of the upper feeder are too large, and some of the BPA Free Clear Borosilicate Glass Water Bottles appear on the bottle body after forming.

　　3. BPA Free Clear Borosilicate Glass Water Bottle has poor initial mold and mold material, insufficient density, and oxidizes too quickly after high temperature, forming small pits on the surface of the mold, causing the surface of the molded glass bottle to be unclean.

　　4. Poor quality of BPA Free Clear Borosilicate Glass Water Bottle mold oil will cause insufficient mold lubrication, lower dripping speed, and rapid change of material type.

　　5. The design of the preliminary mold is unreasonable, the cavity is large or small, and the material droplets are blown and spread unevenly after entering the molding mold, which will cause spots on the glass bottle body.

　　6 The dripping speed of the machine is not uniform, and the improper adjustment of the air nozzle will cause the temperature of the glass bottle to be inconsistent with the mold, and it is easy to create cold spots on the glass bottle body, which directly affects the finish.

　　7. If the glass material liquid in the furnace is not clean or the material temperature is uneven, it will also cause bubbles, small particles, and small hemp billets to appear in the BPA Free Clear Borosilicate Glass Water Bottle.

　　 8. If the speed of the row machine is too fast or slow, the bottle body of the BPA Free Clear Borosilicate Glass Water Bottle will be uneven, and the bottle wall will be different in thickness, resulting in mottling.
