Granulation matters because raw plastic waste, scrap, flakes, powder, and mixed regrind are hard to feed, hard to dose, and even harder to reuse consistently in production. Once the material is turned into granules, it becomes easier to store, easier to transport, and much easier to run through downstream processing equipment.

Extruder pricing is one of the first questions buyers ask, but it is rarely answered with one number. In real purchasing, the cost of an extruder depends on what the machine is expected to do, how much output is needed, what materials will be processed, and how complete the line needs to be. A small lab or pilot setup sits in a very different price range from a production machine built for compounding, recycling, or high-output pelletizing.

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.
