Kronos Precision Extrusion Co., Ltd. is a joint venture between Kronos Polytech GmbH & Co. KG (Germany) and a world-class team of experts, dedicated to advancing high-performance thermoplastic extrusion technologies.

As a specialized manufacturer of thermoplastic profiles, we combine deep expertise in R&D, tooling design, and precision manufacturing to deliver complex profile solutions with exceptional dimensional stability, surface quality, and tight tolerances.

With a global presence across South Korea, Canada, Germany, Singapore, and China, we provide high-quality, efficient solutions to customers worldwide.

We are not a large global corporation. But the standards we uphold—and the philosophy behind them—are anything but small.

We do not build our competitiveness on the sacrifice of our employees and suppliers. Nor do we pursue growth at the expense of quality. Guided by German-engineering principles, we deliver precision manufacturing and responsible technical service to earn lasting trust and satisfaction. We are equally committed to the future. By advancing products with environmentally responsible values, we aim to contribute to the next generation and beyond. Even in times of geopolitical uncertainty and rapid technological change, we remain anchored in what matters most—human dignity and responsibility toward the natural world. We choose quality over price, completeness over speed, trust over scale, and long-term value over short-term gain. That is our way.

Thermal insulation and energy-saving technology for global windows, doors, and curtain walls began its development in the 1970s. Over decades of progress and driven by the "Dual Carbon" goals, it has continuously evolved toward high performance, low carbonization, and smart capabilities.

Kronos has consistently closely followed building energy efficiency trends, actively conducted market research, and explored new concepts and directions in insulation design. This work aims to provide scientifically sound and practical recommendations for enhancing the functionality and energy efficiency of curtain wall, window, and door systems.
