The 2023 Smart City Expo (Kaohsiung) will be held today at the Kaohsiung Exhibition Center. In response to the theme of the conference, "Digital Transformation Creates a New Peak of Smart City", the Metal Center showcased 46 technologies and services to "foresee the new trend of technology" "" is the main axis of activities running through four major theme areas - "Innovative Superpower" exposes the award-winning technologies at home and abroad in the past 6 years; The products jointly developed by member manufacturers, "Interactive Vitality" show a different vitality through exclusive IG filters, FB live broadcasts and digital interactions.

The Metal Center has accumulated rich experience and technical strength in the research and development, processing and application of metal materials. It will present the latest research and development achievements and technology application cases in this exhibition, which is expected to be exciting.

The booth tour of the Metal Center explained the highlights of the technology.

The first thing worth paying attention to is the 4D (3D+heterogeneous) solid phase additive manufacturing technology, which won the double material international award. It can design heterogeneous materials according to the needs of the product, and then use the friction stir welding method to combine the layers of materials into products. Due to the limitations of traditional manufacturing methods, this technology can shorten the process time by 20%, reduce energy consumption by 42%, improve the utilization rate of metal materials, and greatly reduce the waste of processing materials by 40%. , Green environmental protection process without welding fumes.

Due to the combination of the advantages of two different metals, the application of metal composite structures can be carried out according to the special needs of the product. In addition, the customizable products can quickly assist the industry to meet the needs of new product structure development. It has been applied to aerospace and electric vehicle components. and other industries.

Friction stir welding technology is currently applied to electric vehicle battery boxes.

The second item is the real dynamic image spinal surgery assisting system. This technology also won the Double International Award, the National Innovation Award and the Innovation Award.

In the past, when performing spinal surgery, you can only rely on repeated X-ray fluoroscopy images during the operation to update the image data, and the postoperative wound recovery is slow; compared with the existing navigation system, it is impossible to register more than three vertebrae at a time, and the positioning is limited. The size of the mark is too large to correct the spatial information of the vertebral segments in real time. Therefore, Metal Center developed the world's first optical 3D composite positioning technology, which designed the positioning mark as a dodecahedron and miniaturized it. Planning, intraoperative positioning and real-time compensation technology provide a better solution for precise clinical operation requirements.

This system has been tested in 13 cases, with a success rate of 98%. It is planned to be implemented in clinical application this year (112) to jointly strengthen the domestic ecological chain of minimally invasive spinal surgery assisting systems.

The real dynamic image spinal surgery assisting system, the first optical 3D composite positioning technology, and the use of dodecahedron positioning marks will implement clinical applications and strengthen the ecological chain of domestic spinal minimally invasive surgery assisting systems.

The last highlight is the Unmanned Water Vehicle (USV), which is designed in combination with the floating body, which can be quickly disassembled and changed to meet the needs of different tasks.

When sailing in the open sea, it can resist 4-level wind (5.5~7.9m/s), anti-wave height 1m~2m, and has automatic cruise and multi-way point setting remote control function, within a radius of 30 kilometers (inclusive) of the control point It can carry out data transmission and guidance and control tasks, and the vehicle can also carry drones to take off and land and coordinate operations. It is equipped with various sensors for seabed and environmental surveying and mapping, and is aimed at geophysics, seismic surveys, shallow water hydrological fisheries and aquatic habitats. For bathymetry and mapping, the future applications are unlimited.

Lin Renyi, chairman of the metal center, said that the center has long been committed to the upgrading of the domestic metal and related manufacturing industries. At the same time, it has been involved in the medical material industry for many years. To assist the industry towards the goal of smart technology and net zero sustainability, the Future Metal Center will continue to improve technological innovation and development, and contribute to the domestic industry.

The Unmanned Surface Vehicle (USV), combined with the floating body for modular design, can quickly disassemble and change shape, can resist 4-level wind (5.5~7.9m/s), resist wave height of 1m~2m, and has automatic cruise and Remote control function.
