Anyone who is engaged in plastic bag processing knows that an important link in the plastic production process is plastic granulation. Plastic granulation is a process in the process of plastic processing. The quality of granulation directly determines the quality of downstream blow molding. Good or bad, although there are certain technical regulations for plastic granulation, due to the current variety of plastic raw materials, and many plastic raw materials come from plastic waste recycling, these recycled plastics have various characteristics. The process has become more complicated, so the quality of plastic granulation depends on technical experience. It is necessary to master the granulation skills according to the performance of the granulator and daily practical experience, so as to produce high-quality plastic granules. The following is a brief introduction to the production process.

Three Tips for Granules


1. Learn to listen to the sound


The speed of the feeding speed and the change of the temperature, the sound made by the machine are very different. This requires continuous exploration in practice, and we must try our best to keep the machine in the sound state when it is running at its best.


2. Learn to see materials


It is very important to look at the material coming out of the nose, because this is the first key to find the cause. If there is raw material, the temperature is too low and must be heated; if there is coke material, the temperature is too high and the temperature must be lowered, etc.


3. Look at the surface gloss and compactness of the particles


Poor plasticization, loose particles: dull surface is due to improper control of granulation temperature and cooling water temperature. In short, in the process of plastic granulation, you must listen, watch and explore more, so that you can find problems and correct them in time. Plastic granulation skills have to accumulate experience based on the different performance of the machine and your own practical exploration.
