Welcome to Amstar’s PP and HDPE pelletizing line, a system engineered for performance, efficiency, and sustainability. Featuring our Laser Filter Automatic Screen Changing and Slag Discharge System, this line delivers uniform, high-quality pellets even from highly contaminated input materials.

High-Torque Extrusion for Stable Output

At the core of the system are high-torque single screw extruders with specially designed barrels and screws. These ensure: 1、Excellent plasticizing 2、Consistent throughput 3、Smooth, stable operation

Intelligent Feeding System

The process begins with a stainless steel screw conveyor, which moves material smoothly and efficiently. A precision feeder equipped with VFD speed control regulates the feeding rate, guaranteeing consistent flow and preventing overload.

Smart Control & Automation

Stable pressure High slag discharge efficiency Minimal material loss, even with dirty input streams

The Laser Filter Advantage

The Laser Filter System is the highlight of this line. Specially engineered to remove tough contaminants such as wood, paper, and stones, it offers: 1、Automatic screen changing for uninterrupted production 2、Screw-driven slag discharge for continuous impurity removal 3、Real-time monitoring and precise control for easy operation No more manual mesh replacement or downtime—just smooth, continuous processing.

Flexible Filtration Options

For standard recycling needs, the line can also be configured with a double-station hydraulic screen changer, enabling mesh replacement in less than two seconds.

Consistent, High-Quality Pellets

From feeding, extrusion, and filtration to cutting, drying, and storage, every stage of the process is optimized for reliability and efficiency. The result: 1、Clean, uniform PP and HDPE pellets 2、Excellent consistency 3、Ready for reuse in injection molding, extrusion, and other demanding applications

Confidence in Recycling Performance

Amstar’s pelletizing line with the Laser Filter Automatic Slag Discharge System gives recyclers the flexibility to handle the dirtiest materials with confidence—delivering the perfect balance of performance, efficiency, and sustainability.
