Machine for Pelletizing Rigid PP and HDPE Plastic Flakes

Two-Stage Plastic Pelletising Machine

Transforming rigid PP & HDPE flakes into high-purity, reusable pellets for premium manufacturing applications.

Engineered for Excellence

Our pelletising system is designed for superior efficiency, quality, and reliability, ensuring you get the maximum value from your recycled materials.

High-Quality Pellet Output

Produces uniform, dense, and thoroughly degassed pellets ideal for injection moulding and other high-end uses.

Automated & Stable Feeding

VFD-controlled screw conveyors ensure a consistent material feed, automatically adjusting to prevent blockages and ensure smooth operation.

Advanced Two-Stage Filtration

A dual-extruder design with segmented filtration removes coarse and fine contaminants, reducing filter changes and maintenance downtime.

Efficient Degassing & Drying

A “dual-zone” vacuum system and advanced dewatering technology effectively remove moisture and volatiles for superior plastic quality.

From Flake to Finished Pellet

A seamless, four-step process that guarantees the conversion of plastic waste into a valuable manufacturing resource.

1. Consistent Feeding

Washed flakes are fed into the system via an automated, speed-controlled screw conveyor.

2. Plasticisation & Degassing

The material is melted in the first extruder, with volatiles and moisture removed by a dual-zone vacuum system.

3. Melt Filtration

Melted plastic is pushed through a two-stage filtration system in the second extruder to remove all impurities.

4. Pelletising & Drying

The pure polymer is cut into uniform pellets by a water-ring pelletiser and dried, ready for packaging.

Key Component Functions

VFD Screw Conveyor

Provides precise, automated control of the material feed rate, optimising the extruder’s performance and preventing overloads.

Primary Single-Screw Extruder

Dedicated to meticulously melting and homogenising the plastic flakes while performing initial degassing and coarse filtration.

Secondary Single-Screw Extruder

Further plasticises the material and uses a high-mesh filter to eliminate fine contaminants, ensuring final pellet purity.

“Dual-Zone” Vacuum Degassing

This innovative system on the primary extruder efficiently removes volatiles, inks, and moisture, crucial for producing high-quality pellets.

Water-Ring Pelletiser

A robust and reliable die-face cutting system that transforms the molten plastic into uniform granules with high efficiency.

Centrifugal Dewatering System

Combines a vibration sieve with a horizontal centrifugal dryer to rapidly remove surface water, preparing pellets for immediate use.

Frequently Asked Questions

This machine is primarily designed for pelletising washed rigid plastic flakes, including PP (polypropylene) and HDPE (high-density polyethylene). It can also be adapted for other rigid plastics like HIPS and ABS. For heavily contaminated or printed materials, our two-stage system is particularly effective.

A two-stage system offers superior degassing and filtration. The first extruder melts the plastic and removes most volatiles, while the second extruder refines the melt and performs fine filtration. This results in higher quality pellets with fewer impurities and “voids,” and it also reduces the frequency of filter changes, leading to less downtime.

Yes, we offer comprehensive support services. This includes optional on-site installation, commissioning, and operational training for your team to ensure you can operate the machinery safely and efficiently from day one.

All our new recycling machines come with a 1-year limited warranty, covering parts and manufacturing defects. We also provide ongoing technical support and spare parts services to ensure the long-term performance of your investment.
