April, 1990

With a second-hand plastic injection molding machine in a rented corner of a factory that manufactured food packaging, Seongju started off in a rather modest setting.

However, with a clear vision to cultivate a company deeply rooted in principles of customer service, ethical entrepreneurship, and the empowerment of it workforce, motivation was an area in which Seongju’s founding members were not modest.

Driven by a relentless commitment to these values, they laid the groundwork for what would eventually evolve into a dynamic and respected entity within the industry, dedicated to driving innovation, fostering lasting relationships, and making a positive impact on the lives of both customers and employees alike.

A decade following its inception, Seongju embarked on a significant expansion initiative in Cheonan, marking a pivotal milestone in its journey. Motivated by a commitment to deliver exceptional manufacturing services to a growing base of North American clientele, the company strategically augmented its operational footprint.

This expansion was not merely confined to bolstering manufacturing capabilities but also entailed the establishment of specialized teams dedicated to providing tailored support and personalized attention to our valued customers.

With a keen focus on customer-centricity and operational excellence, Seongju fortified its position as a trusted partner in the global manufacturing landscape.

May 2001

As Seongju's operations flourished in North America, the imperative for establishing a local presence became increasingly apparent.

In 2001, the company took a significant step forward by inaugurating its first overseas office in Detroit, Michigan, aiming to deliver expedited and reliable customer services to its growing client base. What commenced as a modest customer support outpost swiftly evolved into a robust regional branch, encompassing a comprehensive suite of functions including warehousing, distribution, technical support, and sales.

This strategic expansion not only underscored Seongju's commitment to providing unparalleled service and support but also reaffirmed its dedication to fostering enduring partnerships and maximizing value for its clientele in the North American market.

Establishing a local presence marked a significant milestone in Seongju's commitment to fostering strong customer relationships and delivering exemplary service.

By positioning ourselves closer to our valued clients, we were able to demonstrate our dedication to customer care and diligence, forging stronger bonds and facilitating more seamless communication channels. Through the collective efforts and unwavering support of our customers, Seongju achieved Tier 1 status from various Original Equipment Manufacturers (OEMs), a testament to our relentless pursuit of excellence and the trust placed in us by industry leaders.

This prestigious designation reaffirms our position as a trusted partner and underscores our commitment to delivering exceptional quality and service in every endeavor.

Over the course of our operational tenure, Seongju has consistently received feedback from clients expressing the desire for an expanded portfolio encompassing assembly services. In response to this discerning feedback and our dedication to enhancing customer experience, Seongju embarked on a strategic initiative. This endeavor involved the acquisition of a 250,000 square foot parcel of land, followed by the construction of a state-of-the-art 60,000 square foot facility located just 20 minutes from our original Cheonan plant.

This purpose-built facility represented a significant investment in our capabilities and infrastructure, enabling us to seamlessly integrate assembly services into our comprehensive suite of offerings. By strategically expanding our operational footprint, Seongju reaffirmed its commitment to meeting the growing needs and expectations of our esteemed clientele, while further solidifying our position as a premier provider of end-to-end manufacturing solutions.
