This system product is a product that directly supplies and heats lubricant oil for smooth operation of the main engine cylinder’s metallic and mechanical movement. Lubricator, a product that supplies lubrication directly to the main engine cylinder liner, can control injection timing and consumption using an electronic control method that responds to the movement of the main engine piston. The alpha lubricator system is based on an algorithm controlling the cylinder oil dosage proportionally to the sulphur content in the fuel and, fuel consumption on particular load of engine. Minimum cylinder oil dosage is required to provide an adequate oil film and detergency properties. Everllence and WIN GD engines are currently applying the second generation Lubricator type, the Everllence type is Mk-I and the WIN GD type is Mk-ε (Epsilon).

Our XR-based aircraft maintenance simulator is officially certified by the Ministry of Land, Infrastructure and Transport (MOLIT) of South Korea for training and education. It provides specialized training environments for the A321, B737-MAX, and B737-800NG aircraft, featuring over 80 detailed modules—including procedures for engine removal, main landing gear installation, and more. This subscription-based simulator is fully compatible with smartphones, tablets, and wearable XR devices, enabling seamless access through a cloud-based web service. Users can train anytime, anywhere—perfect for both remote learning and remote maintenance scenarios. Compared to traditional classroom learning, the XR platform is 4 times more effective and requires only one-third the training time. It also improves user confidence in real-world technical applications by up to 275%. By transforming traditional paper manuals into immersive, interactive training environments, the simulator delivers the next generation of aircraft MRO education for both civil and defense sectors.

The EPNR4000 is a vehicle-mounted 5G base station integrating CU-DU-RU, offering wider service coverage than the EPNR2000. It connects to a separately installed 5G Core and IP-PTT application server in the vehicle, providing 5G services, making it an ideal system for use in disaster situations or military operations.

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.
