Plastic color consistency is one of the fastest ways customers judge product quality, and one of the easiest places for small factories to lose money through scrap, rework, and long changeovers.

​A single screw pelletizing machine combines high torque rotation, high barrel and die temperatures, pressurized molten polymer, and fast-moving pelletizing equipment. Most injuries happen during non-routine moments such as startup checks, screen changes, die cleaning, jam clearing, and maintenance, when guards are opened and people work close to moving or hot parts.

​Yes, a single screw extruder can pelletize mixed plastic waste, but success depends on what mixed means in your feedstock and how the line is configured. In real recycling plants, mixed waste typically carries two challenges at the same time: polymer variation and contamination variation.
