Professional Glass Bottle Manufacturer
Whether a bottle is qualified or not is not completely consistent with whether a bottle has defects. Some defects are not allowed to exist on glass products,
such as various cracks, deformities, insufficient mouth, etc. Another kind of defect is allowed to exist to a certain extent (or range), but it needs to be quantified
to ensure that it is within thestandard of quality system management; for example, bubbles, seams, stripes, etc. We will use precise inspection equipment and
rich inspection experienceto avoid some problems and meet customer requirements more perfectly.
Possible causes of The Problem
Raw materials and processing issues
We will strictly control the procurement of raw materials to ensure the stability of raw materials. Ensure the consistency of glass composition, minimize the stones caused by glass impurities and the stability of physical and chemical properties such as impact strength.
Temperature regulation and air pressure issues
The kiln and annealing temperature are controlled by automated electronic constant temperature to ensure temperature stability, thereby controlling the stability of physical and chemical properties such as stress and water resistance of glass bottles; we use multiple high-performance, high-precision controlled air compressors to ensure the stability of high and low pressures during molding, ensuring that the glass is well molded.
Machine operation issues
The actuators in the main equipment are precisely adjusted according to the molding process to ensure uniform molding. Avoid uneven distribution of glass.
Glass bottle surface treatment issues
Precision machining and high-quality hot and cold end surface treatment are essential to avoid scratches, small collision points and fine cracks during the production of glass containers.
Solutions for Mouth Defects
According to different shapes of glass bottles, reasonably adjust the drip temperature and material shape, the head of the material drop should be smooth, calibrate the scissors to eliminate the cut mark, adjust the center value of the mouth mold and the initial mold, and reasonably adjust the blowing time
Adjust the drip temperature to meet the molding requirements, ensure the matching size and position of the mouth mold and the mold, adjust the time of the mouth mold opening and the mold closing, and match them accurately, and replace the worn clamps
Correctly control the drip temperature and material shape, keep the material weight stable, clean up foreign objects around the core, and check whether the mouth mold and the core match
Reduce the drip temperature to a suitable level, the reverse blowing pressure and time should be appropriate, the machine speed should be appropriate, and the cooling nozzle position and air volume should be appropriate
Adjust the material temperature and material shape to meet the molding requirements, appropriately increase the material weight and maintain the time and pressure of the puffing (blowing), keep the initial mold, mouth mold and core clean and properly lubricated
Solution to Bottleneck Defects
Burrs on bottleneck joints
Appropriately adjust the drip temperature and material shape, check whether the primary mold is damaged, and the inner diameter matching tolerance of the mouth mold and the primary mold should be appropriate
Neck stagger
Improve the matching of the mouth mold and the primary mold, select a mold with good matching between the mouth mold and the primary mold, and adjust the position of the mouth mold and the primary mold to make them concentric.
Bending of bottleneck
Reduce the drip temperature to an appropriate level, reduce the machine speed or increase the cooling air, arrange the nozzles reasonably, check whether the exhaust holes are unobstructed, ensure the appropriate temperature of the mold neck, adjust the mold or adjust the positive blowing head and its position, positive blowing pressure and time
Neck bottleneck is too long
Reduce the drip temperature to an appropriate level, the positive blowing pressure and time should be appropriate, ensure the mold exhaust holes and vertical cooling are unobstructed, the wind line is reasonable, replace or adjust the blowing head and its position, and arrange the position of the cooling nozzle reasonably.
Solution to Shoulder Defects
Shoulder cracks
Reasonably adjust and control the drip temperature, adjust the mold, ensure smooth opening and closing, proper air volume, and adjust the positive blowing pressure.
Thin shoulders
Try to keep the drip temperature reasonable and stable, the material shape should be adapted to the initial mold, the material should be dropped smoothly and straight, improve the coordination between the initial mold and the mold, adjust the reverse blowing pressure and time, advance the positive blowing time, and reasonably adjust the time relationship between the initial blowing, reheating, and positive blowing.
Insufficient bottle shoulders
Reasonably adjust the material temperature, material shape, keep the material droplets from entering the initial mold smoothly, adjust the positive blowing head position and blowing pressure and time, properly adjust the reverse blowing, improve or dredge the wind eye and wind line of the shoulder of the molding mold, adjust the molding mold to open smoothly, without bottles, and keep the mold clean.
Solution to Bottle Defects
Bottle body skew
Adjust and maintain a reasonable drip temperature, adjust the material shape and weight, and keep the drip temperature uniform. Adjust the material channel so that the material drop can enter the primary mold quickly. The machine speed should be reasonable, and the cooling air should be used properly to ensure that the bottle is shaped.
Bottle body joint crack
The drip temperature should be appropriate, the shape of the material drop should be adapted to the initial mold shape as much as possible, adjust the cooling air, maintain the appropriate temperature of the forming mold, adjust the positive blowing pressure and blowing time, and ensure smooth opening and closing of the mold.
Deflated bottle
Improve material properties, adjust the drip temperature, maintain smooth material drop, reduce machine speed, adjust the cooling air, and maintain the appropriate temperature of the forming mold
