Introduction
The cast film machine is designed for the molding of cast film products of polymer materials. It has multiple processing functions such as casting, extrusion, stretching, and compounding, and realizes program-controlled integrated linkage through the PLC system to ensure precise process. Product features include cast film molding of various polymer materials, high-precision guide rails of hidden calender units, and imported melt metering pumps and pressure sensors. Its application range covers cast product research and development, formula optimization, quality control, process parameter optimization, and teaching and scientific research.
Detail & Parts
The Single layer cast film machine ：Focusing on the industry research of polymer material cast film product molding, sheet extrusion molding, material performance testing, process optimization, product quality testing, etc. It can complete molding and processing tests such as extrusion, casting, stretching, and compounding;
- Multi-layer co extrusion casting film machine
- After multiple polymer melts are collected through the co-extrusion die, they become a film melt flow composed of multiple layers of different polymer melts, and after cooling, a multi-layer co-extruded film or sheet is obtained;
- The integrated linkage of PLC system program control to complete extrusion, melt metering, melt pressure monitoring, casting, calendering, winding or cutting and other processes.
- The imported melt metering pump is equipped with a pressure sensor to monitor the melt pressure, ensuring that the melt flow rate is always consistent.
Application
- Film forming simulation: Through calendering or stretching process, the film forming process in actual production is simulated to ensure that the film prepared in the laboratory has similar structure and performance to the film in industrial production.
- Performance testing: The prepared film can be used for various performance tests, such as tensile strength, elongation at break, heat shrinkage, light transmittance, haze, etc., to evaluate the quality and applicability of the film.
- Formulation optimization: By adjusting the raw material formula and process parameters, the laboratory calender/stretch cast film machine can help researchers optimize the film formula to achieve specific performance requirements.
- New material development: For the development of new materials, this equipment can be used to quickly evaluate the forming performance and potential applications of new materials, and accelerate the transformation process of new materials from laboratory to industrial production.
- Quality control: During the production process, laboratory equipment can be used for sampling and testing to ensure that the quality of each batch of film meets the standards and reduce the defective rate.
Features
- Versatility: supports cast film forming and laminating processes of various polymer materials to meet the processing requirements of different materials.
- PLC system program control linkage: through the advanced PLC system, the integrated control of extrusion, casting, calendering and winding processes is realized to improve production efficiency and operation convenience.
- Hidden calendering unit: adopts high-precision guide rails to ensure smooth operation, and at the same time facilitates the disassembly and cleaning of the mold to reduce maintenance time.
- Multi-layer co-extrusion technology: multiple polymer melts are collected through the co-extrusion die to form a film melt flow composed of multiple layers of different polymer melts, and after cooling, a multi-layer co-extruded film or sheet is obtained.
- Precision control: equipped with imported melt metering pumps and pressure sensors, real-time monitoring of melt pressure, ensuring the consistency of melt flow, thereby ensuring product quality.
