SJ Tech

“SJ Tech, name of a research-based advanced technology enterprise Serving our clients tirelessly with innovation and development”

A specialist in mobile-phone and automobile parts manufacturing for over 26 years!

Originally founded in 1987 as Sejin Industry, the company became an incorporated entity in 2003 and changed its name to SJ Tech. To go along with the change in name, SJ Tech also expanded its core product lines to parts for mobile devices, in addition to the already existing product lines for automobiles parts, based on an advanced Die Casting technology and accumulated manufacturing Know-how. With our capability in producing quality parts, we currently provide our parts as a Tier 1 partner to Samsung Electronics, the global number one mobile manufacturer, and Hyundai Mobis, a leading auto parts manufacturer.

Speed, Delivery, and Sincerity, the core values of SJ Tech!

Focusing on our core principles of Speed, Delivery, and Sincerity, we are currently looking to take the next step towards serving the customer. We have recently, with Samsung Electronics, co-developed S63, a new type of high-strength aluminum alloy. We have already made a speedy application of this new material into our new product lines. It is this type of innovation and relentless effort that sets out products apart and one of the reasons we have become a leading parts manufacturer on the market. We believe that we can further reinforce our core competitiveness by advancing towards such essential values, which will become a stepping stone in the evolution of our company.

Full of hopes and dreams! Global Die Casting!

In an age of unlimited competition, a unique competitiveness becomes a must for companies` sustainability and success in business. We will become a global manufacturer of parts for mobile phones and automobiles based on cutting edge technology and quality products. WE endeavor to provide our products to meet global demands. We kindly ask your attention and support.
