Importing a large-scale extrusion line from China is not only about comparing quotations. For serious buyers, the real decision is about production stability, long-term operating cost, material adaptability, delivery reliability, and supplier support after the machine arrives.

Melt temperature is one of the most important factors in plastic extrusion because it directly affects product appearance, dimensional stability, material dispersion, output consistency, and energy consumption. If the melt temperature is too low, the material may not plasticize fully. If it is too high, the polymer can degrade, burn, discolor, or lose key performance properties.

Making PET granules is not simply a matter of melting waste plastic and cutting it into pellets. In real production, the result depends on feedstock quality, moisture control, melt stability, filtration, and pelletizing precision. For recyclers and plastic processors, the real target is not just output volume, but clean, uniform PET granules that can move smoothly into downstream applications. That is why a dedicated PET granulator machine matters.
