How to solve the problem of poor transparency of PET bottle?
Reason: The poor transparency of PET bottles may be related to factors such as the quality of PET raw materials, the temperature of the heating lamps and the bottle blowing process etc.
Solution:
1. Check the quality of the raw materials for PET preforms to ensure that the quality of the raw materials used is high-quality;
2. Adjust the temperature of the lamps in the heating section and the bottle blowing parameters to ensure that the PET preforms are fully and evenly heated;
3. Clean the mirror inside the mold, keep it clean and tidy, check the water cooling system, and prevent impurities, oil stains and other factors from affecting product quality.
How to solve the problem of pearl luster on PET bottles?
Cause: Pearl luster may be caused by high temperature during the operation of the bottle mold or other impurities in the PET preform.
Solution:
1. Optimize the mold cooling water system and reduce the mold temperature;
2. Replace high-quality PET preforms and avoid using preforms produced with excessive recycled materials;
3. Increase the stretching ratio to make the bottle wall more uniform.
How to solve the problem of big thickness rate of change of PET bottle wall?
Reason: Large thickness variation of bottle may be caused by uneven heating of preform, wear of mirror inside mold or unstable blowing pressure.
Solution:
1. Check the heating lamp and adjust the angle of the reflector to ensure uniform heating of PET preform;
2. Replace damaged bottle mold to avoid affecting the molding of PET bottle;
3. Use voltage stabilizing equipment to ensure stable pressure of gas source for bottle blowing machine.
How to solve the scratches on the surface of PET bottles?
Reason: Scratches on the surface of PET bottles may be caused by damage to the internal mirror of the mold, wear of the conveyor belt or improper operation of personnel.
Solution:
1. Replace the mold, or regularly polish and maintain the internal mirror of the mold to keep the internal mirror smooth;
2. Replace the severely damaged conveyor belt to avoid scratches on the bottle body caused by friction during the bottle transmission process;
3. Regularly train employees, formulate corresponding operating systems and specifications to avoid scratches caused by human factors.
Air pressure, mold, parameters and bottle quality may be factors that lead to unstable bottle blowing by the PET blowing machine. The solutions include checking the wear and sealing of the air compressor, gas pipeline, air pressure regulating valve, mold, reasonably adjusting the bottle blowing process parameters, and checking the bottle quality.
- Check and maintain equipment: First, make sure that the air compressor, air pipe and air pressure regulating valve are in good working condition. This includes the air compressor's ability to provide stable air pressure; the efficiency of the air pipe in transmitting air pressure; the air pressure regulating valve adjusts the working air pressure suitable for the bottle blowing process.
- Check the bottle mold: The wear of the inner wall mirror and Harvard line of the mold is also an important factor affecting the stability of bottle blowing. The mold should be checked regularly for wear and replaced with a new mold in time; at the same time, ensure that the mold is well sealed and replace the seals in timely to avoid air leakage during the bottle blowing process and avoid affecting the quality of the bottle.
- Adjust the parameters of the bottle blowing machine: Solving the unstable bottle blowing can also be done by reasonably adjusting the bottle blowing process parameters. This includes adjusting the lamp heating temperature ,the pre-blowing time and adjusting the stretch ratio to avoid material accumulation at the bottom of the bottle.
Pre-blowing ensures that the PET preform and the stretching rod maintain a certain distance in the bottle blowing process to avoid contact, ensure that the bottle can be properly stretched and formed as expected, and ensure product quality.
The pre-blowing process is to adjust the pressure and time settings in the bottle blowing process to help the PET preform separate from the stretching rod during the stretching process, so that the bottle wall material can be evenly distributed, stretched longitudinally and transversely according to the expected effect, and the material is not contacted with the inner wall of the bottle mold too early.
The quality of the bottle is affected by the position, pressure and flow of the pre-blowing. Defects such as the bottom center point deviation, uneven wall thickness of the thinning part, and whitening of the bottle may be affected by the pre-blowing settings. Therefore, the correct setting of the pre-blowing parameters will directly affect the quality of the bottle.
In summary, pre-blowing plays a vital role in the production of bottle blowing process. It ensures the quality and molding effect of the bottle through precise control and appropriate parameter settings, and is an important means to improve production efficiency and product quality.
Embryos. First, use the PET preform machine to make PET raw materials into plastic preforms.
Preheating. In order to shape the PET preform according to the shape of the mold, the preform needs to be heated first. The body part of the PET preform is heated, and the bottle mouth part is kept cool.
Blow the bottle. Put the uniformly heated preform into the machine mold, and blow sterile high-pressure air into the preform. With the blowing of high-pressure air, the preform extends around until it extends into the shape of the mold.
Demoulding. After blowing the bottle, the machine starts to exhaust and demould. The blown PET bottle is ejected from the machine as the mold is opened.
