FAQ

How to extend the service life of the blowing machine?


To extend the service life of the bottle blowing machine, you need to do the following: First, regular maintenance and repair of the equipment, including cleaning, lubrication and replacement of wearing parts, etc.; second, the reasonable use of the equipment, to avoid overloading and improper operation; third, to keep the equipment clean and dry, to avoid moisture and corrosion; fourth, to replace the aging and damaged parts in a timely manner, in order to ensure that the equipment's normal operation and stable performance.

How to maintain the mold of bottle blowing machine?


Maintenance of blowing machine mold is very important, you need to clean the residue and dirt in the mold regularly to avoid affecting the quality of bottles and the service life of the mold. At the same time, the mold should be checked for wear and tear, and if there is any wear and tear, it should be repaired or replaced in time. In addition, it is also necessary to check whether the assembly position of the mold is accurate, to ensure that the mold closing pressure and sealing time and other parameters meet the requirements.

How to maintain the heating lamp of the blowing machine?


The heating lamp of the blowing machine needs to be checked and replaced regularly. If the lamp is found to be aging or damaged, it should be replaced in time to avoid affecting the heating effect and the quality of bottles. Meanwhile, the surface of the lamp should be kept clean to avoid the accumulation of dust and dirt affecting the heating efficiency.

What are the possible reasons and solutions for the perforation of bottle bottom stretching?


Bottle bottom stretching perforation may be caused by insufficient temperature, too long delay stretching time, too large stretching ratio, too thin at the bottom of preform tube, and too sharp stretching rod head. Solutions include increasing the temperature, shortening the delayed stretching time, reducing the stretching ratio, improving the design of the bottom of the embryo tube and rounding the head of the stretching rod.

How to avoid the problem of uneven wall thickness of PET bottle?


Uneven wall thickness of PET bottles may be caused by the position of stretching pole not in the center of preform tube, asymmetric blowing holes or different diameters of holes, too low stretching multiplier or too small blowing ratio, non-rotation of preform tube in the heating furnace as well as uneven thickness of preform tube wall or uneven injection density. The solutions include adjusting the position of the stretching rod, adjusting the position and diameter of the blowing hole, increasing the stretching multiplication or blowing ratio, checking the rotation device and improving the quality of the embryo tube.

What are the possible reasons and solutions for the offset of the water spout position at the bottom of PET bottles?


PET bottle bottom spout position shift may be caused by the start of blowing time too early, the stretching rod is not lowered to the bottom, the centerline of the stretching rod and the bottle axis is shifted, the wall thickness of the preform tube is not uniform or the density of the injection is not uniform, and the heating is not uniform and so on. The solutions include delaying the blowing time or increasing the descending speed of the stretching lever, adjusting the position of the magnetic pole switch, adjusting the position of the stretching lever, improving the quality of the preform and improving the heating conditions.

How to solve the problem of pearl luster whitening in PET bottle?


PET bottles with pearl luster whitening may be caused by the heating temperature is too low, uneven thickness of the embryo tube wall, or the embryo tube thickness is too thick, resulting in insufficient heating penetration and other reasons. The solutions include heating up or slowing down the rotational speed, improving the quality of the germ tube, and reducing the thickness of the germ tube or raising the outer cover of the heating device to increase the temperature of the surface layer of the germ tube.

What are the possible reasons for the poor transparency of PET bottles?


Poor transparency of PET bottles may be caused by the following reasons: heating temperature is too high, heating time is too long, compressed air contains water, the injection molding tube itself is opaque, the design of the tube is not suitable, the blowing and expanding ratio is too small, etc. The solution includes lowering the temperature, shortening the heating time, and then blowing and expanding. The solutions include lowering the temperature, shortening the heating time, removing water with dryer, improving the quality of preform, improving the design of preform size and reducing the diameter of preform.

What are the main types of bottle blowing machines?


There are two main types of bottle blowing machines: automatic and semi-automatic. Fully-automatic blow molding machines are operated by robots, and the two steps of blowing (heating and blowing) are combined together to complete the blowing process, which greatly improves the production efficiency. While semi-automatic bottle blowing machine requires manual participation in some steps.

What is a bottle blowing machine?


Bottle blowing machine is a kind of equipment specially used for producing plastic bottles, which blows and pulls the softened plastic bottle embryo into the desired bottle shape by heating it and then inflating it with high pressure in the mold.
