[INQ. NO. 1910E26] Sealink Corp. is a company with cutting-edge technologies. Thanks to the know-how it has built up for over 25 years, it has succeeded in designing, developing and commercializing a non-lubricant dry mechanical seal by dramatically resolving issues arising from the existing oil-lubricated mechanical seals.
Based on its vision to contribute to safety and life respect by reducing leak explosion accidents 
in the workplace to one-tenth, Sealink is growing into a global company while doing business with Samsung Electronics, LG Chem, Intel (USA), and others.
A day mechanical seal is a sealing unit that prevents leakage of chemical gases, liquids, etc., from cracks between a rotating shaft and stationary housing when mixing chemical substances in an industrial agitator. Such seals are widely applied in petrochemicals, semiconductors, shipbuilding, steel, pharmaceuticals and other industries, and they are especially essential for petrochemical and semiconductor facilities.
The existing mechanical seals need lubrication, meaning they include explosion hazards due to lubricant releases. Meanwhile, Sealink’s dry mechanical seal (called ‘S-Seal’) is safe from leakage-caused explosion accidents and is most suitable for petrochemical and semiconductor machines that are sensitive to lubricant contamination as it is a non-lubricant seal that does not need a device to supply lubricants.
Sealink’s high vacuum and pressure rotary feedthroughs, linear feedthroughs and rotary unions are manufactured and supplied through strict quality-controlled processes in accordance with ISO 9001, ISO 14001 and OHSAS 18001 certifications. And, the reliability tests conducted by the Korea Institute of Machinery & Materials (KIMM) and the secured certificate of reliability have proven that over 95% of the quality of these products is maintained for up to 18,000 hours (or two years) of operation.

With its convenient user interface and functions that help users to proceed through each of the work steps, the work efficiency can be maximized. This product is an AR-head-mounted tablet-based solution that prioritizes work safety.
temperature range, the lithium primary battery is a high capacity battery being sold to the industries that require long serviceable batteries without replacement or energy, and logistics fields that require batteries serviceable even in harsh temperatures and environments.
Because of these characteristics, the lithium primary battery is commonly used in military radios, night vision goggles, various weapon systems including cannonballs, exploratory oil rigs, cardiac defibrillators, tracking devices, and IoT devices. Because its service life is long, although the price is higher than alkaline batteries, it is broadly adopted to the costly devices like tsunami alarms floating in the sea.
Lithium primary batteries have taken center stage in the growing Smart Grid market. Lithium primary batteries are used in the power supply of smart meters including electric meters, gas metesr, water supply meters, and heat meters. As switching to Smart Grid is progressed considerably in the USA, Europe, India, and China, its market is expending already.
words, the detector (PD) is divided into four sections. Sensing the heat and controlling and maintaining temperature steadily can be performed simultaneously. What actually makes this possible is the ceramic structure of substrate. This basically enables the detector to realize the maximum level of 0.6A/W high sensitivity when and where higher sensitivity is required.
ODTECH is specialized in the semiconductor and sensor businesses with 20 years of experience and know-how with its highly skilled operators and engineers. Not only focusing on the domestic market, the company has been making consistent efforts to expand its business globally, and finding potential customers and markets by being more creative and innovative.
More specifically, such systems help ODTECH to meet the needs of customers in various industrial sectors by providing total solutions, from bare dies to sensor modules and systems. In addition, providing all necessary raw materials such as chips from its own fab lines (wafer factories) from 
Korea and China enables ODTECH to more efficiently operate and manage its production processes. As a consequence, ODTECH helps its customers to gain a competitive-edge in existing or potential markets.
In particular, the company has completed the development of “conductive polymer hybrid electrolytic capacitors” and “electric double layer capacitors,” all of which are used in a wide range of fields including information, 5G communication, hybrid vehicles, wind/solar power and other new renewable energy and power-generating equipment in line with the recent increase in the demand for eco-friendly and high value products.
Meanwhile, the company is systemically controlling the quality of its products based on a three-step management system in order to grow itself into a general electronic components maker. And, it is also efficiently managing the manufacturing processes through an Enterprise Resource Planning (ERP) system and a real-time Manufacturing Execution System (MES).
time of this manual method and minimize the generation of toxic odors, thus ensuring the safety of working in a closed space.
be operated with low power, so it only needs one fifth of solar panels and batteries compared to other products. Energy Harvesting System work is relatively easy and always generates constant power regardless of the surroundings.
It is possible to do uninterruptible work for expansion and additional changes. The Bus-Bar (Horizontal Bus) Automatic Connection System is adopted. This product applies a bulkhead structure to each major item to ensure safety.
Application of Inner Corona Protection (ICP) reduced partial discharge. Jigs and products manufacturing by 3D reverse engineering improved shape accuracy. It was installed at unit #3 generator in Ilsan Power Station for test bed, and was still providing commercial service as of May 12, 2019.
measuring equipment and evaluation methods, the AIS-Series in which the IIT test method is applied, is a nondestructive, economic, and efficient measuring method, evaluating any mechanical properties from ultra-fine nano scale to macro scale of operating industrial facilities to provide solutions for reliability issues.
