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.

We overcome industrial barriers even in extreme environments of ultra-high temperatures. VITZROCELL's High-temperature batteries are utilized in extreme environments where high performance is demanded, such as drilling equipment and pipeline inspections.

Developed and manufactured by MPS Microsystems based on customer specifications, this lens actuator forms an essential component of a laser guidance system for unmanned flying objects. It enables 2 lens groups to be displaced individually over a total range of 48 mm and makes it possible to focus a laser over a distance of several kilometres. The main technical difficulty inherent to this actuator lies in meeting very stringent requirements for alignment between the two lens groups (< 10 µm) and in maintaining a very small tilt of the lenses over their entire stroke (lateral deviation < 2 µm). The key part making it possible to ensure such specifications is a frame machined by milling from an aluminium block, into which the 2 drive systems are fastened. These systems each consist of a Ø16 mm brushless motor and a Ø4 mm ball screw with an axial play of less than 5 µm. Backlash-free and frictionless sliding of the lens holders is ensured by standard L306 linear ball bearings manufactured by MPS Microsystems.

The UHF-band TRX module features transmit diversity, allowing selection between two transmit ports and providing an output power of at least 1 W. It includes a gain control function for transmission and an internal local oscillator for IF-to-UHF upconversion. Transmit functions also include ALC (Automatic Level Control) and over-temperature protection. On the receive side, the module selects one of two input channels and performs downconversion. It supports AGC (Automatic Gain Control) with a response time of 80 µs, enabling real-time gain adjustment based on input signal level. The dynamic range of the receive input spans from -100 dBm to -20 dBm, and the noise figure is 5.0 dB or less. Both transmit and receive paths include built-in path self-test functions.

The Global Aerospace & Defense Team's Business Service Providers (BSP) Directory is designed to help U.S. aerospace and defense companies identify professional service providers to assist them in the assessment, completion, and/or financing of an export transaction.

Lumir, in collaboration with the Electronics and Telecommunications Research Institute (ETRI), developed and integrated this device for lunar exploration aboard Danuri (KPLO, the Korea Pathfinder Lunar Orbiter), Korea's first lunar probe. This device successfully demonstrated its performance by receiving BTS music videos transmitted from the Moon to Earth, achieving Technology Readiness Level (TRL) 9.

HII ensures the flight readiness of aircraft worldwide, providing mission-critical test, weapon loading and hydraulic power generation equipment, parts and services for both military and commercial end markets.
