Forming is a production process in the whole manufacturing process of raw pulp and oil glass bottle manufacturers, and the direct cause of forming defects comes from all walks of life. What are the common defects in the whole process of pulp and oil glass bottle forming?
(1) Cracks
Cracks are a common flaw in glass bottles. It may be very fine, some of which can only be found in refracted light and real life. The most common areas are the cap, weak spots and shoulders, and the body and bottom of the bottle are also often caused by cracks.
(2) Uneven thickness
The laminated glass on the glass bottle is uneven throughout. The key is that the temperature of laminated glass drops is not uniform, and the viscosity of the part with high temperature is small, and it is easy to blow thin; The lower part of the temperature is more frictional and slightly thicker. The temperature of the solid model is not uniform, the high temperature side of the laminated glass cooling slow, easy to blow thin, the low temperature side, because the laminated glass cooling fast and blow thick.
(3) Deformation
The droplet temperature and the action temperature are too high, and the glass bottle dislocated by the forming die is not completely shaped, and generally will step and deform. Sometimes the bottom of the bottle is still soft and the conveyor belt marks are carved and the bottom of the bottle is uneven.
(4) Not tactful
The drop temperature is too low or the solid model ultra-low temperature will make the lips, shoulders and other places not smooth, resulting in notches, dented shoulders and unclear texture and other defects.
(5) Cold spots
The soft spots on the surface of laminated glass are called cold spots. The key cause of this kind of defect is the ultra-low temperature of the solid model, which is mostly caused when the production starts or the standby reproduction.
(6) Manifestations
Glass bottle manufacturer surgical sutures show or lip edge protruding defect. It is caused by inadequate production and processing of solid model prefabricated components or inadequate installation. The solid model is damaged, there is waste on the surface of the joint, and the laminated glass material has fallen into the initial mold before the top core is mentioned too late to enter the position, which will cause some laminated glass to be pressed into or blown out of the gap.
(7) Wrinkles
The folds come in various shapes, some are folds, some are thin folds. The main reason for the creasing is due to the ultra-low temperature of the material drop, the material drop is too long, and the material drop does not fall in the middle of the initial mold and sticks to the inner wall of the mold core.
(8) Surface defects
The surface of the bottle is hairy and uneven, which is mainly caused by the uneven surface of the mold. The lubricating grease of the solid model is not removed or the soft brush with oil is too dirty, which will also reduce the performance of the bottle.
(9) Bubbles
The bubbles caused in the whole process of forming are generally several large bubbles or several bubbles concentrated together, which is different from the well-proportioned flocculent of the laminated glass itself.
(10) Scissors
Visible scratches left on bottles and cans due to poor cutting. A material drop often appears 2 scissors marks, the upper scissors mark left the bottom end, damaging the appearance. The scissors below are left on the cap and are often the source of cracks.
In general: when purchasing raw pulp and oil glass bottles, check at the beginning to avoid the above mentioned situation. We look forward to the content of the shared resources, so that everyone can actually apply to daily life.
