In the process of polymer material research and development, the accuracy, flexibility and operability of the experimental equipment directly affect the research and development efficiency and quality of new materials. As an advanced cast molding equipment designed for laboratory environment, the small precision extrusion casting test line has become an ideal choice for colleges, scientific research institutions and corporate R&D centers to conduct film and sheet polymer material molding experiments with its compact structure, multi-functional integration, convenient operation and strong repeatability.

The small precision extrusion casting test line consists of a precision single-screw extruder, a cast die head and a precision cast auxiliary unit, which completely covers the whole process from raw material plasticization, melt extrusion, cast molding, traction cutting to winding and reeling. Although the whole system is small in size, it is fully functional and can simulate the main process flow of the industrial cast production line, enabling researchers to obtain process data close to actual production under small-scale experimental conditions, thereby effectively guiding the technical parameter setting in the subsequent pilot or mass production stage.

Among them, the precision single screw extruder is the "heart" of the whole system. It adopts high-performance alloy screw and precise temperature control system to ensure uniform temperature and stable pressure of materials during heating, conveying and plasticizing, and improve the consistency of melt quality. With advanced control system, users can adjust key parameters such as rotation speed and temperature curve according to different material characteristics to achieve refined management of extrusion process.

The casting die head is manufactured with high precision and has good melt distribution performance, ensuring uniform thickness, smooth surface and neat edges of cast film. The die head structure is reasonably designed and easy to disassemble and clean, which is suitable for the experimental needs of various thermoplastic materials, such as PE, PP, PET, PLA and other environmentally friendly polymer materials.

The casting auxiliary unit of small precision extrusion casting test line integrates cooling roller, traction device, trimming system and winding device, realizing one-stop operation from casting to finished product winding. The cooling system adopts efficient constant temperature control to ensure the rapid cooling and shaping of the film; the traction speed is steplessly adjustable to meet the stretching requirements of different materials; the winding device runs smoothly and the tension is controllable to avoid wrinkles or looseness of the film roll, ensuring the stability and repeatability of the experimental results.

In terms of structural design, the small precision extrusion casting test line adopts a split modular structure, and the components are flexibly connected, which is convenient for transportation and on-site installation, and is particularly suitable for use in laboratories with limited space. At the same time, the integrated operation interface simplifies the control logic, allowing experimental personnel to quickly get started without complex training, significantly improving the experimental efficiency. Compared with traditional large-scale industrial equipment, the system has lower energy consumption, small footprint, and fast startup speed, which is very suitable for high-frequency experimental tasks such as formula debugging, process optimization, and new product trial production.

In addition, the small precision extrusion casting test line is also highly scalable and compatible. Users can select different die widths, temperature control systems, automatic thickness measuring devices, online monitoring systems and other functional modules according to specific research directions to meet the diverse needs of scientific research. For research projects that require data analysis and process records, a data acquisition and storage system can be optionally configured to achieve real-time recording and export of key parameters, facilitating the data management of scientific research results.

The small precision extrusion casting test line is becoming an important tool in the field of polymer material research and development with its complete process flow, stable performance, flexible operation and excellent repeatability. It not only shortens the product development cycle and improves experimental efficiency, but also provides strong technical support for the exploration of new materials and new processes. It is one of the indispensable core equipment of modern materials science experimental platforms.
