Pelletizing plastics is the process that includes melting and cutting polymers into easy-to-handle plastic pellets. Understanding pelletizing system and feeding system will help you select the right plastic pelletizing machine!

Pelletizing Systems

Pelletizers are the essential parts of plastic pelletizing machines. There are several types of pelletizing methods. Die face cutting system, also known as hot die cutting pelletizing system is the most popular used system among the other options. In this system, the molten polymers pass through the die head, and later on a rotating blade cuts the hot polymer at the surface of the die.

    • Hot Die Water-ring Pelletizing
    • Underwater Pelletizing System (UWP)

  • Strand Pelletizing System

  • Automatic Strand Pelletizing System

Feeding Systems

The common feeding types for plastic pelletizing recycling machines include hopper feeding and side feeding.

  • Hopper Feeding Pelletizing System

    A feeding hopper feeds materials directly into the extruder without preheating. Harder plastic scraps or rigid regrind such as crushed HDPE bottles are suitable to be recycled by the hopper feeding system. Soft plastic materials such as crushed and washed PE films are also processable, which makes a flexible solution for the hopper feeding pelletizer.

  • Side Feeding Pelletizing System

    A side feeding is a stable and continuous measure to feed materials. It allows stable extruder feeding even when the bulk density varies. So the overload and underload can be avoided, which assures maximum efficiency.

  • Cutter Compactor Feeding Recycling Pelletizer

    A compacting and pelletizing system combines the function of the cutter, crushing, compacting, plasticization and pelletizing in one step. It is an efficient solution for plastic film, HDPE bags, plastic raffia, zipper, nonwoven bags and foaming materials repelletizing.
