Process Considerations for High Speed Blow Molding Machine products

At present, the preform openings used by High Speed Blow Molding Machine products in the industry when producing hot-fill bottles are generally divided into crystallization openings and non-crystallization openings, and the non-crystallization openings are divided into 28 openings and 38 openings. As far as the bottle mouth is concerned, the crystallized mouth can withstand 100 degrees without deformation, but the upper limit of the heat resistance of the non-crystalline mouth is only 92 degrees.

If it is higher, the bottle mouth will be deformed by heat. The preform and grammage used for blowing medium-temperature bottles are preferably selected according to the requirements of hot filling. If it is designed according to the single-mode 1700 bottles/hour, the cycle of the single-mode is 2.1 seconds, 1/4 of which is the time to open and lock the mold, and the remaining 3/4 is the process time, minus the balance, Sealing, stretching, and pre-blowing take 0.2 seconds. In fact, the time for high-pressure forming and holding pressure crystallization is only 1 second, the time for cold blowing and setting is 0.3 seconds, and the time for closing and closing the rod is 0.1 seconds. The time allocation mentioned here is just a reference value, and the specific time should be adjusted and guaranteed in real time through the control panel during production. Strictly speaking, compressed air must be processed by a freeze dryer before it can be used for high blowing and cold blowing, and because the pipeline between the air compressor and the blowing machine is long, in order to avoid the exposed pipeline from being exposed to the sun , The compressed air pipeline used for cold blowing and setting must be covered with thermal insulation cotton to ensure that the temperature of the air source will not be affected.
The above are the common problems in the use of High Speed Blow Molding Machine products. The bottle blowing machine causes different problems in the bottle blowing process. On the one hand, it has problems with the structure of the blowing machine itself, and on the other hand, it is for debugging. Problems, most of the faults are caused by improper use of human factors. When you encounter problems, don’t worry, carefully analyze the difficult fault points of the bottle blowing machine, and check them one by one or consult the sales service engineer of the bottle blowing machine manufacturer (keep with the technician frequently) connect).
