Seal Units

https://korean-machinery.com///inquiry[INQ. NO. 1803M03] Seal units are used in semiconductor frontend process and petrochemical fields – especially, large OLED devices, CMP devices in semiconductors and reactors, and mixers in petrochemicals. It plays a critical role in this field.
Seal units are divided into two categories of mechanical seals and magnetic seals. These can be applied to different fields. Mechanical seals are used in pressured conditions and usually are applied in the petrochemical industry and must be used with a lubricant supply system. Magnetic seals, on the other hand, are used in vacuumed conditions based on ferrofluids. They are usually applied to semiconductor industries that use vacuum seals a lot. For this reason, seal (feedthrough) manufacturers generally target just one field, petrochemicals or semiconductors.
Sealink’s seal, however, can use both fields and make up for the weak points of mechanical seals and magnetic seals. Sealink has various kinds of seal units, with rotary & linear feedthrough among the most prominent items. There are rotary feedthroughs in the market, and these can just rotate. Therefore metal bellows should be used if the customer wants rotation and linear motion. Sealink products, however, are very simple and compact. It can do all this at the same time with just one unit.
Sealink offers customized sealing units to meet customers’ application requirements as well as standard sealing units for a wide range of industries including semiconductor, LCD and OLED industries, pharmaceutical and chemical processing industries, etc.
All its products are manufactured under strict quality control and in ISO 9001 / ISO 14001 certified manufacturing facilities in Korea, and Sealink is committed to continue improving its products and technology for further customer satisfaction.
Sealink Corp. was founded in March 2014, and has since then been expertly developing and designing sealing solutions for vacuum and pressure. It supplies mechanical seal units, rotary unions to petrochemical, semiconductor, steel, heavy industry, etc.
Sealink founder Rhee Hee Jang explains, “I founded the company and I was on a roll based on experience of working at small-medium research as a researcher and an employee. There, however, were some problems so I closed down the business. Then in 2013, I got new knowledge and inspiration for restarting the business.” Taking this opportunity, he succeeded in taking on new challenges in 2014.
Although Sealink was founded not too long ago, CEO Rhee has been in the seal field over 30 years and he improved the technology, supplying the Samsung mass production line and Intel U.S.A. Also he achieved recognition of Sealink’s potential from POSCO Capital, Samsung Venture Investment, Rechallenge Angel No.1 Fund, and Industrial bank of Korea by getting new investments.

Exports by Eight Major New Industries Hit US$ 31.47 Billion in 1st Half, Proving Their Value as Driving Forces behind Exports

https://korean-machinery.com///inquiryExports by new industries are growing at a higher rate than total exports. The proportion of new industries’ exports in total exports is on a gradual rise, turning heads toward eight new industries including electric cars, robots and bio-health products.
According to the Ministry of Trade, Industry and Energy, exports by the eight new industries in the first half of the year amounted to US$31.47 billion, accounting for 11.3% of Korea’s total exports. Except for solar power generation exports, they shot up 20% from the previous year.
Exports of the seven items, excluding robots, showed increases.
Next-generation semiconductors and next-generation displays took the lead in driving up overall performances while new energy, bio-health and aerospace exports contributed to a spike in exports by new industries.
Exports of electric vehicles in the first half of the year boomed by 90.9% thanks to strong sales in Europe, which boasts of good charging infrastructure, and the launch of Korean automakers’ main electric car models in the United States.
In the aerospace sector, Corporate Korea delivered six Korean-made T-50s and eight FA-50s, and exports rose due to an increase in exports of aircraft parts in the first half.
Next-generation displays posted record-high biannual earnings, driven by rising demand for OLEDs for smartphones and increased TV sales at home and abroad.
A hike in prices of next-generation semiconductor NAND flash semiconductors and a rise in demand for them significantly elevated MCP exports and exports of system semiconductors switched to an increase from a drop in the previous year.
Exports of high-tech fiber and high-priced synthetic resin rose thanks to an increase in demand for cuttingedge new materials sparked off by a global economic recovery
Exports of finished drugs and biopharmaceuticals edged up in emerging markets of bio-health products and exports of medical devices such as ultrasound imaging devices inched up.
Exports of EVs, batteries for electric vehicles, and smart meters, which are features of the new industry energy, increased sharply in the first half.
Since the first introduction of the solar power HS code this year, the solar power industry exported US$1.26 billion in the first half of the year. Among total exports, PV modules and polysilicon accounted for 55% and 37%, respectively.
Exports of batteries for electric cars and ESSs rose in the first half of the year as demand for electric vehicles grew among major automakers in the EU and the United States.
On the other hand, despite the increase in exports of production robots to India and Vietnam, robot exports recorded a slight decrease in the first half of the year due to the delayed launches of new products and intensifying competition in Europe, the main market.
Among the eight new industry items, six new items –- electric cars, aerospace, new energy industry, nextgeneration displays, next-generation semiconductors and advanced materials –- enjoyed double-digit export growth and all items except for robots posted increases.
“Also in the second half of the year, exports are expected to climb, led by next-generation semiconductors and displays. It is also forecast that the launches of electric cars and service robots will play a positive role in exports by the new industries,” said Lee Min-woo, an assistant manager of the Import and Export Department at the Ministry of Trade, Industry, and Energy. “The Ministry of Trade, Industry, and Energy announced that the ministry will check Korean industries’ international competitiveness fields related to the 4th industrial revolution through the eight new industries’ export statistics and utilize them as basic statistics for new industrial policies.”

Fan Filter Units

Fan Filter Units
https://korean-machinery.com///inquirySince its foundation in 1989, Wonbang Tech has achieved constant growth and development in the mechanical facility industry with its top-notch technology and outstanding quality. The company has strived to make every effort to provide customer satisfaction and better service for its customers based on the philosophy of “Be recognized by our customer as the best supplier.” As a result of these efforts, Wonbang has accomplished many projects successfully such as, “STMicroelectronics & STATS ChipPAC Singapore,” “Samsung Semiconductor, LCD & SDI,” “Hynix Semiconductor,” “LG Display & SILTRON,” “OCI,” “SK E&C,” “SK Innovation,” “Intel Vietnam,” etc. The company’s vision is to be a ‘Global Company’ in the mechanical facility engineering industry field.

In the semiconductor, LCD and biotech industries, the manufacturing factories require clean rooms. Clean rooms remove pollutants such as fine dust particles produced during the manufacturing process inside. The polluted air circulates via fans. The circulation process can remove most of the pollution mixed in the air.

Compared to other clean room systems, the company’s F.F.U. Clean Room system is more convenient for airflow distribution and alteration control. In later stages, more pressure is formed in the Fab section to prevent pollutants from flowing inside. Accordingly, most large-scale semiconductors, LCD, and PDP factories completed after 2000 use the F.F.U. Clean Room system.

The F.F.U. system is composed of an aluminum case, motor-fan, filter and controller. The standard normalized sizes are 1200mm x 600mm and 1200mm x 1200mm. Nonstandard sizes are also available upon request. The case is mainly made out of aluminum. Rolled plate and anodized aluminum cases are also available upon request. The filter varies with the cleanliness class of the clean room.The F.F.U. motor is one of the most important parts to keep the blades rotating for airflow. There are two different types: AC and BLDC. The BLDC motor is a brushless DC motor that eliminates the mechanical contact between sites, such as the brush and commutator.
