Double-screw degradable plastic pelletizing machine

Product Overview

This product is a co-rotating parallel twin-screw extrusion pelletizing equipment under the PURUI brand, originating from Nantong. It is a customizable double-screw degradable plastic pelletizing machine with no fixed price, tailored according to the customer’s production requirements. The equipment integrates plastic recycling, compounding and modification, and functionalization into one, featuring excellent strong shear mixing performance. It can produce high-quality modified recycled pellets and functional masterbatches in a single step, meeting the processing needs of various material systems.

Core Features

The co-rotating parallel twin-screw extruder boasts three core features: First, its superior mixing performance, enabled by a strong shear mixing structure, ensures thorough blending of materials, guaranteeing uniform and stable modification effects; second, its excellent self-cleaning capability effectively prevents material residue, reducing cross-contamination between different production batches and ensuring product purity; third, its flexible modular configuration allows adjustment to suit diverse processing needs, accommodating various types of material systems. Additionally, the equipment adopts a multi-stage vacuum degassing design, thoroughly removing volatiles and impurities, resulting in pellets with strong performance and stable appearance, while also flexibly adapting to multiple process requirements such as filling, toughening, coloration, and degradation.

Core Advantages

First, the equipment employs a co-rotating twin-screw strong mixing structure, delivering excellent modification results and enabling a one-stop recycling + modification process without the need for multiple sequential steps, significantly simplifying production; second, its multi-stage vacuum degassing design ensures thorough removal of volatiles and impurities, keeping impurity levels below 0.8%, resulting in pellets with strong performance and stable appearance, suitable for direct supply to high-value customers in automotive, electronics, and other sectors; third, it can flexibly adapt to various process requirements such as filling, toughening, coloration, and degradation, meeting the processing needs of different materials; fourth, key components are sourced from top-tier brands, ensuring low failure rates and long service life, with annual stable operating hours exceeding 7,500 hours and production efficiency improved by over 50%; fifth, it can produce high-value modified pellets, increasing the market selling price of finished pellets by more than 18% after modification, significantly boosting product gross margins and helping enterprises greatly expand their profit margins.

Application Fields

The equipment has wide-ranging applications across multiple processing scenarios: In the field of filler modification, it can handle calcium carbonate, talc powder, barium sulfate, titanium dioxide, ceramic powder, wood flour/plant fibers, and other inorganic fillers; in the area of reinforcement modification, it processes short glass fibers, long glass fibers, carbon fibers, and other whisker-based reinforcement materials; in masterbatch preparation, it produces carbon black masterbatches, color masterbatches, flame-retardant masterbatches, degradable masterbatches, and other specialized functional masterbatches; in compounding modification, it is suitable for thermoplastic materials/elastomers, polymer alloys, and cable compounds, including PVC cable compounds, low-smoke halogen-free cable compounds, PE insulation/sheath compounds, PE cross-linked cable compounds, and special-purpose cable compounds. Moreover, the equipment can also be applied to plastic recycling and modification, fiberglass-reinforced pellet production, color masterbatch/functional masterbatch manufacturing, degradable plastic compounding and pelletizing, high-end PET recycling pelletizing, and other specific production scenarios involving filler and toughening modifications.

Target Customer Groups

The target customer groups for this equipment include manufacturers of modified plastics, high-end recycled pellet processing plants, functional masterbatch producers, degradable plastic companies, and suppliers of automotive/electronic component materials—businesses that place high demands on material modification effectiveness, product purity, production efficiency, and product added value. The equipment’s features and advantages precisely match these production needs.

Solutions to Industry Pain Points

Addressing numerous pain points within the industry, this equipment offers effective solutions: First, it resolves the issue of poor mixing and impurity removal in single-screw equipment, which cannot produce high-end modified materials, by leveraging strong shear mixing and multi-stage vacuum degassing to ensure both modification quality and pellet purity, enabling the production of modified pellets that meet high-end requirements; second, it improves the situation where modification requires multiple steps, lengthy processes, high costs, and significant material losses, by completing the recycling + modification process in one go, shortening the process by 40% compared to multi-step modification and reducing labor and energy costs by 25%; third, it overcomes the challenge of low added value in recycled pellets, which previously prevented entry into high-end downstream markets, by producing high-value modified pellets that can directly supply automotive, electronics, and other high-value customers, thereby enhancing product profitability; fourth, it avoids the problem of unstable equipment performance and inconsistent batch quality by using top-tier brand components, ensuring strong equipment stability with annual stable operating hours exceeding 7,500 hours, thus guaranteeing consistent batch quality.
