Poongsan has been producing a variety of copper and copper alloy plates, ranging from copper products for everyday life to high-tech industrial materials. These copper and copper alloy plates, which are recognized as high-quality materials at home and abroad, are representative industrial basic materials that are widely used in all industrial fields, including automobiles, electrical and electronics, semiconductors, communications, construction, and machinery. Poongsan has various casting facilities, including the world's largest shaft furnace, a hot mill capable of continuously rolling 6-ton slabs, a tandem mill, and a 20-stage cold rolling mill, as well as various hot and cold rolling facilities and heat treatment furnaces. We are building a large-scale integrated production system from the casting process to finishing processes such as cutting and packaging. Poongsan's rolled products are produced in various sizes depending on the type, ranging from 630mm in width, 0.03mm in thickness, and thickness tolerance to 2/1000mm. These products have accurate specifications and physical properties and a smooth surface thanks to the establishment of a thorough quality control system using cutting-edge inspection equipment. Excellent. Poongsan's copper and copper alloy rolled products are produced in a variety of ways, including pure copper, brass, phosphor bronze, nickel silver, cupronickel, and special alloy (PMC26 and other) depending on the alloy composition and casting method. In particular, in response to market demands for new high-strength copper alloys due to technological advancements such as the Internet of Things and electric vehicles, we have developed new alloys (P1000HS and others) and are applying them to high-tech products requested by customers.

QPL certification is a system in which the US government guarantees the quality only for products that have passed strict local company inspections made of 150 tests and verifications under the supervision of the US government. Yeonhab Precision obtained the certification in Asia for the first time after 10 years of application. In particular, with the successful QPL registration for the first time in Asia, Yeonhab Precision is the first and only company in Asia which got the qualification of marking “MS” with the title of “Korea’s first MIL-DTL connector”. We will provide customers with the best products as we have the sense of the pride of developing the QPL certified connector with our own technology in Korea.

CATIS™ is an ultra-high-resolution, small satellite imaging radar device independently developed by Lumir. It consists of three components: the radar signal transmission/reception device SCEU, an active phased array antenna SATA, and a data downlink antenna KaPA. This X-band imaging radar device is designed for small satellites weighing 150 kg, offering an ultra-high resolution of 0.3 m. It transmits wideband RF signals to the observation area while orbiting at an altitude of 500 km and receives the reflected signals to acquire Earth observation data.

Large mirrors are crucial in various optical systems, particularly long-range multi-spectral setups for defense, surveillance, and commercial use, like UAV optics and agricultural temperature monitoring. Aerospace applications, such as satellites and telescopes, are common. These mirrors come in different shapes and materials, including Al, Si, Ge, and Cu, spanning visible, UV, and IR spectrums. By using advanced CNC grinding, polishing, and diamond turning we provide precise surface forms, with tight tolerances, and multispectral performance. Our mirrors, up to 700mm in diameter, provide impressive specifications: 0.05% radius tolerance, less than 0.5Fr P-V irregularities, 0.1Fr RMS at 0.633μ, and sub-40Å RMS roughness. MKS Ophir's proprietary coatings enhance spectral performance and surface durability. Contact us to set a meeting at ADEX Seoul
