Thermoplastic Granulation and Compounding

Optimized productivity for every line

Tailored Solutions for Every Compounding Need

Bausano extrusion lines for the compounding and pelletizing of plastic materials are designed to deliver high performance across a wide range of materials: PVC, polyethylene (PE), polypropylene (PP), ABS, PS, PLA, and masterbatch formulations. Depending on material characteristics and production goals, plants can be configured with single-screw extruders or parallel co-rotating twin-screw extruders, both designed in-house.
Every line is engineered to ensure:

Stability and consistent compound quality, even with complex recipes or recycled materials
Precise control of process stages, from mixing to pelletizing
Maximum adaptability to technical formulations with additives, mineral fillers, or natural fibers
High productivity levels, with consistent output even with complex formulations

Bausano Granulation and Compounding Lines

The pelletizing process follows a controlled sequence: dosing, melting, degassing, filtration, cutting, and cooling. Bausano lines are designed to support every stage with configurable, easily integrable components, ensuring an efficient result for every type of material.
Three different cutting modes are available, selectable based on the characteristics of the compound:

Hot face cutting: ideal for temperature-sensitive materials, it ensures uniform cutting directly at the die with forced cooling.
Downstream of the cut, the pellet is conveyed onto a vibrating tray with forced air cooling, equipped with separators and interchangeable screens. This configuration ensures perfect pellet separation, preserving shape and uniformity.
Underwater cutting: perfect for polyolefins and complex compounds, it allows immediate cooling of the pellet in suspension.
Side air cutting: suited for extruded cylindrical strands, it ensures precise particle size thanks to air cooling with an integrated cyclone.
Water ring cutting: creates a film of water between the die and the knife, stabilizing the process and reducing dust formation.

Technologies, Application Sectors, and Processable Materials

Bausano designs both single-screw extruders and parallel co-rotating twin-screw extruders, offering technical solutions calibrated to compounding needs, material type, and process complexity.

Single-screw extruders

Suited for homogeneous thermoplastic materials
Simplified structure for efficient maintenance
Ideal for continuous, low-energy-consumption processes

Co-rotating twin-screw extruders

Designed for compounding PVC, fillers, additives, and fibers
Optimal for applications requiring intensive mixing and effective degassing
Wide versatility on recycled materials and complex formulations

The lines are used in sectors such as automotive, construction, packaging, electrical engineering, medical, and consumer goods, where material quality, traceability, and process repeatability are required. Headquartered in Italy with a global presence through a network of technical partners, sales offices, and service centers, Bausano ensures technical support at every stage of the project.

Bausano technologies are suited for processing a wide variety of thermoplastic materials, including: Polypropylene, polyvinyl chloride (PVC), expanded polystyrene, polyurethane, acrylonitrile butadiene styrene (ABS), thermoplastic elastomers (TPE)
All materials can be processed in customized configurations based on the specific applications and performance required.

A Plant Built Around the Customer's Needs

Every Bausano plant is born from close collaboration with the customer, in a process that begins with an analysis of production needs and continues through to the line's commissioning. Bausano's headquarters in Italy is supported by an international network of technical offices, commercial partners, and service centers present in the world's major markets, ensuring direct support at every stage: from design to after-sales. Every project is managed with a consultative, flexible approach, adapting layout, configurations, and process parameters to specific applications. This makes it possible to optimize not only the plant's performance, but also its integration within the customer's production environment. A notable example is Mill Polímeros, a company based in Ecuador specializing in the production of PVC compounds for the industrial sector.

For this customer, Bausano designed and supplied a complete line, custom-configured to process high-viscosity materials and achieve a high-quality, stable pellet compliant with the required standards. The system was integrated with solutions for precise temperature control and degassing management, ensuring production continuity, reduced scrap, and simplified maintenance operations. This project is a concrete example of Bausano's ability to build solid, lasting technical partnerships, supporting customers with reliable, customized solutions oriented toward maximum operational efficiency.
