    FAQ

    Q1: What are the primary applications of the ATE series parallel twin-screw extruder?

    A: The ATE series is a high-performance system designed for plastic modification and compounding. It is widely used for color masterbatch production, functional masterbatches (like flame retardants or UV stabilizers), polymer blending, and filling (such as CaCO3 or Talc). Its co-rotating parallel twin-screw design provides excellent mixing and shearing capabilities, making it the preferred choice for compounding facilities requiring high dispersion and homogenization.

    Q2: How does the ATE series ensure superior dispersion and mixing quality?

    A: Our ATE series utilizes co-rotating parallel twin-screw technology, which creates a high-intensity shearing action and inter-meshing effect. This ensures that pigments, additives, and fillers are uniformly dispersed within the polymer matrix. By precisely controlling the screw configuration and residence time, the ATE extruder achieves ultimate homogenization even for high-loading or temperature-sensitive formulations.

    Q3: Can the screw and barrel of the ATE extruder be customized for different formulations?

    A: Yes. The ATE series features a fully modular design for both the screw elements and the barrel sections. This allows users to easily reconfigure the screw geometry (feeding, melting, shearing, and venting) to match specific processing requirements for different polymers. This flexibility makes the ATE series a versatile "all-in-one" solution for R&D labs and toll compounders who handle various material grades.

    Q4: What components ensure the long-term reliability and high-torque performance of the ATE series?

    A: The ATE series is equipped with a high-torque, high-speed gearbox and a precision-engineered safety clutch to prevent overloads. The screw elements and barrel liners are made from high-wear-resistant and corrosion-resistant alloys, ensuring a long service life even when processing abrasive fillers. The integration of advanced oil cooling and heating systems ensures stable temperature control during high-intensity 24/7 industrial production.

    Q5: What auxiliary systems can be integrated with the ATE twin-screw line for a complete production solution?

    A: To provide a turnkey solution, the ATE series can be integrated with various loss-in-weight feeders, side feeders for fiberglass, and multiple pelletizing options including water-strand, water-ring, or air-cooled hot face pelletizing. Our PLC-based control system synchronizes all auxiliary units, allowing for precise control over the entire compounding process from a single interface.
