HEF DURFERRIT JAPAN List of Products and Services

HEF utilizes femtosecond laser technology for surface treatment, providing a vertically integrated business solution from research and development to industrialization. The combination of micron-sized and nano-sized processing enables multi-scale texturing. It is possible to work with high-hardness materials such as tungsten carbide as well as delicate materials, ranging from a few nanometers to several hundred micrometers. We modify surface materials to enhance properties such as adhesion, friction, wettability, fine texturing, conductivity, and wave trapping (electromagnetic shielding and absorption), thereby improving performance. 【Features】 ■ Femtosecond laser parameters ■ Multi-shot laser processing process ■ Ultra-fast processing rates ■ Vision system ■ Functionalization of surfaces *For more details, please refer to the PDF document or feel free to contact us.

Our company designs, develops, and manufactures a high-capacity "continuous film deposition system" suitable for surface treatment of metal bipolar plates (separators) for fuel cells, and we offer contract processing coating services. We also provide coating services tailored to output and usage conditions, as well as the development of optimal surface treatments based on customer needs. 【Reasons to Choose Us】 ■ Experts in PVD coating ■ Own dedicated labs and factories for fuel cells ■ Extensive knowledge of the automotive industry ■ Knowledge of continuous coating lines ■ Knowledge of automatic inspection ■ Applicable even under harsh conditions *For more details, please refer to the materials available for download in PDF format. Feel free to contact us with any inquiries.
