**Product 2: Double Stage Extruder**
Our company offers a two-stage planetary gear extruder with different discharge systems tailored for various applications. This system is composed of three main parts:
- **Part 1:** Feeding Extruder Unit includes a feeding screw and the planetary screw group.
- **Part 2:** Vacuum-Degassing Chamber removes volatile gases to ensure higher quality output.
- **Part 3:** Discharge Unit pushes out the plastified and de-gassed mixture.
The first stage extruder operates at a high speed for efficient mixing and high output, while the second stage uses a larger-diameter single screw that runs at a lower speed. This design helps prevent overheating and improves temperature control during processing.
**Pelletizing Line (Capacity up to: 2000 kg/h)**

**Introduction & Application of Planetary Roller Extruder**
The planetary group is the core component of the planetary extruder. It typically consists of a planet barrel, a main spindle (the sun), and several satellite spindles (screws) that rotate together in harmony. The inner surface of the barrel and the outer surfaces of the satellite screws are designed with 45-degree helical threads, ensuring efficient mixing and material flow.
Made from special steel and hardened through nitriding, the planetary group offers superior resistance to corrosion and wear. The main spindle and satellite spindles are also made from high-quality steel and undergo induction heat treatment for enhanced durability.
Compared to other extruder systems, the planetary extruder provides significantly better plasticization due to its homogeneous and highly efficient mixing action. Our planetary extruders deliver at least 10 times better homogeneity and plastification than twin-screw or single-screw extruders.
With a compact design, the planetary group allows for easy dismantling and cleaning, making it ideal for users working with multiple colors. The self-cleaning feature of the planetary screws ensures no residue remains in the system, which is crucial for maintaining product quality and reducing downtime.
This advanced technology is used for producing high-quality plastic products such as soft PVC, rigid PVC, wood-plastic composites, acrylics, and PE composites. It also supports optimal degassing in a vacuum chamber, high production capacity (500–2000 kg/h), energy efficiency, and fast formula changeovers.
Our customers include manufacturers of PVC cables, hoses, pipes, profiles, wood-plastic composites, PE composites, curtain rails, floor covers, wall panels, shrink films, rain gutters, and PVC sealings.
