Sungil Machinery. Co., Ltd has localized various kinds of high-precision couplings for the fi rst time in Korea.
Currently, its share of the Korean coupling market is over 60 percent. Sungil’s couplings have been exported to 25 countries worldwide. Support units, power locks and other factory automation parts, other main items of Sungil, are manufactured and off ered to the domestic and oversea markets based on the top-tier precise quality.

The company has continuously aimed for new product development to meet its customers’ diverse needs and will strive to be a global top-tier parts manufacturer in the factory automation industries.
Couplings are core parts to transfer motion and power that can absorb misalignments and vibration for accurate rotation. The SRB Series are radial beam-type fl exible couplings that are made of high-strength aluminum alloy in one-piece structures. Sungil Machinery has maximized the advantages of the German VMT type and made up for weak points.
The product features high torsional stiff ness, a highly permissible torgue and stability in high rotational speed and a low moment of inertia. A major characteristic of the Oldham Coupling is its excellent fl exibility and a wide range of parallel misalignment acceptability. No restoring force leads to a litt le weight (load) on the bearing and shaft.
Ball screw support units are excellently standardized and have very precise straightness, squareness and concentricity for ball-screw support. Power locks clamp a shaft with a hub very precisely and strongly. Their uniform material property makes the power locks easy to dissemble and reuse.
Expanding Overseas Markets
As a leading coupling manufacturing company in Korea, Sungil Machinery has supplied world-class products to companies manufacturing display, mobile device, semiconductor manufacturing equipment and industrial robots.

The company has been focused on boosting the competitiveness of the FA components market in Korea.
They are now exporting small precise couplings, support units and FA components to Japan, Germany and 20 other nations.

Its branch was opened in China and its sales corporation was established in Japan. Sungil Machinery also set up sales agencies in Europe, Southeast Asia and the Middle East to expand its overseas markets. The company is increasing its exports based on excellent quality and competitive prices.

By realizing a 10:1 turndown ratio, it enables the user to control the temperature with the unit of 1C. It is designed to prevent the generation of adverse wind and protect itself from being frozen to burst. Operating silently, it guarantees stable combustion through proportional air controlling.
The maker’s hot water storage type combi boiler is also equipped with a heat exchanger for both sensible and latent heat.
The hydraulic breaker is the most popular excavator att achment in the world. It is used for road construction, demolition and mining. It is operated by hydraulic pressure from excavators. AJCE has produced various ranges of hydraulic breakers since 1990, from one-ton mini excavators to 60-ton large excavators.
The strength of Kwangnam GSK lies in its integrated system that encompasses all processes, from design to mass production. Thanks to the strength, cost reductions and quality consistency, coupled with its exclusive 2800T full-size die-casting equipment make Kwangnam GSK one of Korea’s best companies in the fi elds of die-casting and aluminum access fl oors.
An access fl oor system is installed at 10cm to 30cm from ground level. Power and communication cables can be installed in the fl ooring itself without piping or cable trays and it allows for concentrated air-conditioning of important equipment, which is ideal for machine rooms, semiconductor manufacturing facilities, and offi ces.


The eff orts of the company to be the No.1 player in the industry has led it to being accredited for its quality and to achieve product competitiveness through K/S certifi cation, certifi ed test records, performance certifi cate, and excellent product certifi cate and self-quality assurance company. It keeps a promise with customers to be a strong company and does its best to provide affl uence to customers’ lives for its products.
Casement windows are mainly used as ventilation windows or escape windows, and are opened from the inside toward the outside. The maximum opening angle is 90 degrees.
As for curtain wall windows, a polyamide insulation material is applied between the main member and the fi xing plate for the primary insulation, and polyurethane is applied to the middle section of the fi xing plate for the secondary insulation. In addition, polyamide is applied to the member that is connected to the external cap for the third insulation. Thus, the curtain wall window is a highly insulated window.
