⚫ Successful processing of foldable core parts

⚫ ‘Sandblasting method’ also developed

⚫ Wet etching method patent pending

⚫ Business discussions with large corporations  

Sewon Hitec Co., Ltd. is a total processing solution company located in Seokjeok-eup, Chilgok-gun, Gyeongbuk, and processes mobile phones, electronic parts, household goods, home appliances, and automobile parts.

The company began with the establishment of Sewon Chemical in Gumi, Gyeongsangbuk-do in 1994, established an etching factory in Sangyeok-dong, Daegu in 2004, expanded the factory to Geomdan-dong, Buk-gu, Daegu in 2005, and later converted to Sewon Hitec in 2007 and took its current form. In particular, with the recent development of foldable phones, the Inner Hinge, a core component of the foldable, was successfully processed using wet etching, upgrading the etching technology to the next level.

In early 2021, in response to a request from a customer that technology for processing the inner hinge using dry etching rather than wet etching was needed, the 'sandblasting method', a method for dry etching, was developed. As the demand for parts using sandblasting increases, Sewon Hitec is a specialized company that can manage etching as a whole in a company that focuses on wet processing by establishing a business site that can specialize in dry etching in addition to wet etching, introducing equipment, and hiring technology development personnel, engineers, and field operators, etc. is reborn as These achievements are said to have had a significant impact on the company's growth, marking another leap forward. In particular, technology-enabled foldable phones are becoming a huge hit globally and are expected to have a significant impact on future corporate growth. Additionally, as product specifications increase, Sewon Hitec's material development technology is expected to grow along with it.

Sewon Hitec has applied for a patent on a dry etching method using sandblasting and a patent on methods for improving the performance of equipment and wet etching of aluminum, and is also making every effort to build an R&D system.

Sewon Hitec is expanding its business area into a total processing solution company from electronics to automobiles. With the belief in creating the best quality through quality-first management, we aim to be the best company in the world in everything from automobile parts to electronic products such as mobile phones and TVs. In Korea, we plan to develop sandblasting equipment that can process the surface of the material and process holes with a joint development organization, and develop equipment that can process only a part of the surface of the material after producing a prototype. In addition, we are developing and commercializing technology to process parts in line with customer product improvements and changes.

CEO Young-ki Jang said, “Our company responds quickly to customer needs through a combination of small-scale, high-mix production lines and automation-based mass production lines,” and added, “We prioritize customer satisfaction through thorough quality control and innovation, and pursue eco-friendly and ethical management.” “We will definitely fulfill our social responsibilities and roles,” he said.
