Dose-Feeding Plastic Pelletizing Machine

Product Overview

The dose feeding pelletizing line is designed for stable and accurate feeding of irregular rigid flakes/lumps and densified soft materials, supporting continuous pellet production for recycling plants and compounders.
It is widely used for HDPE / LDPE / PP recycling pellets, and can also handle densified film, woven bags, raffia, foam and other pre-treated materials with a dose feeder on the feeding inlet.

Key Advantages

• Adjustable feeding speed helps maintain stable output for different material shapes and bulk density.

• Integrated process design supports lower material loss (target: ≤2%) and consistent pellet quality through synchronized control.

• Cutting options available: die-face / water-ring cutting or strand cutting (model-dependent).

Suitable Materials

HDPE bottles & rigid scraps, PP rigid regrind, pre-crushed pipes/containers/lumps; densified PE film, PP raffia, PE/PP woven, PE foam and similar pre-agglomerated feedstock.

Applications

• Plastic Raw Material Production: Produces PP/PE/PVC pellets (reference: ISO 1873-1) for injection molding, extrusion and blow molding, helping downstream processes keep stable pellet size and density.

• Recycled Plastic Processing: Turns film/pipes/bottles scraps into pellets with recycling efficiency up to 98%; melt filtration with 120-mesh filter helps remove impurities (dust/metal particles) and improve pellet purity.

• Masterbatch Production: Supports color masterbatch (pigment content 10–50%) and functional masterbatch; additive dispersion degree target ≥95% to reduce color streaks and performance inconsistency.

Output Pellet Use

Pellets can be used for granulation compounding, injection molding feedstock, extrusion-grade materials, and recycled pellet supply chains, depending on formulation and filtration configuration.
