Sewon Hitec Co., Ltd. is a company that specializes in wet etching and processes electronic components, household goods, home appliances, and automobile parts that are processed through wet etching. With the recent development of foldable phones, the company succeeded in developing a new technology to process the inner hinge (reinforcement plate), a key component of the foldable, using a wet etching method, upgrading the etching technology to the next level. In addition, we have developed dry etching technology using sandblasting, marking another leap forward. As foldable phones have become a huge hit, it is expected to have a significant impact on future corporate growth. As product specifications increase, Sewon Hitec's materials Development technology will also grow along with it.

If half processing equipment is localized, the production and processing method can be localized in Japan, thereby retaining the original processing technology and registering a patent to make it difficult for foreign companies to enter. The company has already acquired domestic and overseas patents and is making every effort to protect its technology. 

As the volume demand for Inner Hinge continues to increase, Sewon Hitec is always planning to expand its business through the development of new technologies in addition to the existing wet etching. Through close relationships with customers, it is possible to obtain information about models to be developed in advance and quickly are responding appropriately. The sandblasting method also achieved the result of capturing the customer's prior information in advance, producing parts that meet the customer's requirements, and creating employment effects.

Sewon Hitec CEO Young-ki Jang said, “Due to the sandblasting process, we are continuously recruiting not only management staff, but also sandblasting machine operators and inspectors. “I am pleased to be helping in a small way in resolving employment issues that have recently become a social problem,” he said.
