As the world's leading supplier of plastic machinery solutions, SUMINO will join hands with its precision 3-layer co-extrusion casting machine to make a grand appearance at this exhibition. With excellent technological innovation, precise process design and deep industry, Sumino Seiko will present a series of industry-forward-looking intelligent, energy-saving and environmentally friendly solutions to global customers at the exhibition, adding a strong touch to the exhibition.
Innovative Technology Leads the Future, Breakthrough in Co-extrusion Casting Technology
Seiko's 3-layer co-extrusion casting machine represents its technological breakthrough in the field of plastic processing equipment. The equipment integrates the most advanced co-extrusion technology, can process a variety of different materials at the same time, and is suitable for the production of high-end packaging films, composite materials and high-performance plastic films. Through precise process control, the 3-layer co-extrusion casting machine can significantly improve the physical properties, transparency and protection of the film material, and customers' demand for high-quality, multi-functional plastic film.
At this exhibition, Sumino Seiko will demonstrate the advanced technology of this equipment on the spot, especially the innovation in multi-layer co-extrusion technology and precision temperature control system. These technologies not only greatly improve production efficiency, but also help customers achieve lower energy consumption and higher product consistency. Through precise production control, Sumino Seiko's co-extrusion casting machine brings customers higher market competitiveness and lower production costs.
The control system is being upgraded

In order to further improve the performance and reliability of the equipment, Sumino Seiko has upgraded the control system of the 3-layer co-extrusion casting machine. The equipment displayed in this exhibition uses Siemens S1500 series control system, equipped with Siemens special temperature intelligent module, to ensure more accurate temperature control and faster response in the production process. With its high performance, modular design and powerful data processing capabilities, Siemens S1500 series control systems can achieve more intelligent production monitoring and optimization.
With this upgrade, Seiko's equipment can accurately adjust key parameters such as temperature, pressure and speed in the production process in real time, maximizing production errors and improving production efficiency. At the same time, the application of the temperature smart module further optimizes the energy efficiency of the equipment, reduces energy waste, and brings customers a more environmentally friendly and efficient production experience.
Highlights of Precision Casting Film Production Line
In this exhibition, Sumino Seiko will showcase its precision casting film production line, covering the following components:
• ABA structure extruder: provides stable multi-layer co-extrusion casting film production capacity, optimizes material distribution and film physical properties.
• 6-component vacuum feeding system: ensure uniform feeding of materials and improve production efficiency.
• Precision filter device: ensure the high purity of the product and avoid impurities from affecting the membrane material.
• In-die composite die head: interlayer composite for different materials to ensure the excellent performance of film materials.
• Interchangeable molding machine: Improves production flexibility and supports the production of membrane materials of various specifications and uses.
• X-ray system: used for thickness detection and uniformity control of film materials to ensure the stability of the production process.
• CCD defect detection system: automatically detect surface defects of film materials to improve yield.
• Double-station winding system: improve winding efficiency and achieve efficient and continuous production.
Through this complete set of high-end configurations, Sumino Seiko's cast film production line can not only provide excellent products and consistency, but also greatly improve production efficiency and production costs.
Green Environmental Protection and Energy Saving Technology
Haruno Seiko has always regarded it as one of the core directions of product development. Its latest environmentally friendly 3-layer co-extrusion casting machine fully considers energy saving and resource recycling in equipment design, maximizing energy consumption and waste generation. Through sophisticated temperature control systems and optimized heating control technology, Seiko's equipment can not only effectively consume energy in the production process, but also help customers achieve a more environmentally friendly production process.
In addition, Sumino Seiko will also showcase its other technological achievements in green manufacturing, including low-carbon emission technologies and efficient energy recovery systems, providing industry customers with more competitive green solutions.
