[Chungcheong Ilbo Correspondent Lee Joo-hyeon] Long-lived companies tend to become family businesses. From grandfather to father, from father to son, and descendants inherit the management right from generation to generation. When business becomes a family business, it is possible to conduct a stable business with more responsibility than any other company. In Cheongju, North Chungcheong Province, Dongil Glass Co., Ltd., located in Songjeong-dong, Heungdeok-gu, is considered as a representative family-run business.

Kim Young-jin (75), a second-generation entrepreneur, has found his way in his parents' business that started in 1940 and is continuing his 75-year family business. Since 2003, Kim Jung-hwan (42), the eldest son of CEO Kim, has also participated in the management. It is a true family business, not a mere succession of wealth.

As the name suggests, Dongil Glass is a company that specializes in glass production (KS certified company, Duolight Club best quality company). Mainly, 'argon gas', which is an inert gas that has better thermal insulation performance than air, is injected into RoUI to make double-layer glass that maximizes thermal insulation performance.

Double glazing is double glazing with a space of about 1 cm between two glass plates. It is widely used as a window material for high-end buildings because of its high sun protection, soundproofing and thermal insulation effects. As the market for building materials that satisfy both aesthetics and energy efficiency is rapidly growing in the era of high oil prices, it has high value as a new growth engine.

It also produces double-sided coated triple-layer glass and sound-insulating laminated glass. The Cheongju Factory (land 3636 m2, manufacturing facility area 1865 m2) produces an average of 700 m2 of glass per day. When the second factory is completed in Ochang, North Chungcheong Province, in March, it is expected to produce 2,000 square meters of glass every day. Dongil Glass is a company recognized in the region enough to undertake the construction of high-end buildings such as Hyundai Department Store and Gwell City.

In November 2013, it was listed as a prestigious long-lived company selected by the Small and Medium Business Corporation, and in December of this year, it received a promising small and medium-sized business certificate (certification period until December 2016) from Cheongju City. Dongil Glass, which is also a family company of the business group, is also focusing on R&D business to improve the processing technology of low-e glass.

Dongil Glass's main focus is on product quality and expansion of production of functional glass. Dongil Glass joined the Duolight Club, a representative multi-layer glass brand group of Korea Glass Industry in December 2003, and has continued quality management. is in progress

An official from Dongil Glass explains that it has three factors from production to construction and after-sales service, and is responding quickly to the increasing demand for functional glass. The technology passed down through generations is positioned as the best competitiveness not only in North Chungcheong Province, but also in the central region.

Successful family successors have one thing in common. It is the flexibility to accept new things while preserving the traditions such as the spirit of the early days. On the 29th, at 10:30 am, at the 1st Cheongju Factory of Dongil Glass located in Songjeol-dong, Heungdeok-gu, Cheongju-si, Kim Young-jin and Kim Jeong-hwan, who have inherited the family business for 3 generations, We met. Young-jin Kim (75), CEO of Dongil-yuri, Cheongju, who is succeeding two generations, wakes up like dawn and works all day without a chance to sit down. 'The early bird catches the worm'. It is because of the stubbornness of his father, who had always adhered to this method during his lifetime.

Kim Jung-hwan, who has been leading Dongil Yuri with his father, CEO Kim since 2003, also goes to work at the same time every day to see management work. "He said.

"Since when have you been working?"

As soon as I sat down, I started asking questions. CEO Kim breathed a sigh of relief with his characteristic, kind smile.

“Let’s see… I was 20 years old back then, so this is my 55th year. I became the CEO when I was 38.” He remembered the difficult early days of the company. "I just graduated from Cheongju High School in 1959 and jumped into the business front. I was the eldest of two boys and seven girls. I had no choice but to earn money. I used to do it, but I was so envious of my friends who wore college uniforms every vacation and took their form. I was attending Cheongju University at that time, and even on weekdays, I wore white dusty work clothes and carried plate glass."

To borrow his words, he really had to work day and night. It was then. Because I wanted to feed my younger siblings even if I put pasting in my mouth. Looking at the hands of CEO Kim wriggling as he groped for his memories, he saw small scars on the glass engraved here and there like medals of time.

"Everyone who uses glass is like this. Until the 1960s and 1970s, the simple cutting operation of cutting and inserting glass into a wooden door frame was all there is to it. Not now. The performance varies greatly depending on how the glass disc is processed."

He also said that it is much easier to work these days. This is because his son, Kim Jung-hwan, planning director, oversees the overall business and even sales. In addition, since the planning director Kim graduated from Korea University's business department and obtained an MBA in the United States, CEO Kim's trust is inevitably deep.

they say “It is common and most desirable for the CEO’s family to find the right person in the CEO’s family to appoint a successor to replace him and keep the company maintained and developed.” I will work hard."
