TECHNICAL FEATURES
Our mission at ASTI remains unchanged across the generations:
to deliver technology and products that earn the unwavering trust of our customers.
Technology Development
We have established an integrated development framework that covers everything from circuit design, software development, mechanical design to quality evaluation, enabling us to achieve superior performance and enhanced reliability in our products.
Furthermore, we are driving technological innovation for the next generation. This includes power electronics to support carbon neutrality and the development of medical devices that utilize our unique ultra-fine molding and processing technology.
Production Engineering
To achieve the Monozukuri (art of manufacturing) that balances efficiency and superior quality, we actively promote the introduction of automated equipment alongside our unique in-house technologies, such as advanced image inspection systems. These systems detect microscopic defects instantly, ensuring stable, high-quality production and high throughput across all our lines.
Quality Management
To deliver quality that brings “satisfaction” to every customer, we have established a robust quality assurance system based on international quality management standards. In addition to ISO 9001, we are fully compliant with rigorous automotive industry requirements, including IATF 16949 and ISO 26262.
By implementing unified quality management across all domestic and overseas facilities, we provide safe, secure, and reliable "ASTI Quality" globally.
