Sales of LDS products, which range from very small to very large solutions, make up 55% of GU’s revenue and its main markets include automotive, governmental bodies, aerospace and defence and electronics. GU has also had a great deal of success as a supplier to automotive electrical battery vehicle manufacturers with customers including SB LiMotive, LG Chem, SK Daejon, Hyundai Namyang Research & Development Facility and Sepang.
GU was founded by Sung-Hak (Simon) Kang in 1999. A Bachelor in Physics and with a Masters degree in sound and vibration from Bookyeong University, Korea, Mr. Kang worked for Brüel & Kjær for ten years as a sales engineer primarily involved with automotive, electronics and education segments before fulfilling his dream of starting his own company.
With more than 400 customers from the world of testing, GU has a total of fifteen employees divided as follows – five in Sales, six in Service and Engineering, two in Administration and two Design Engineers for customised solutions. GU’s services include Vibration Testing, Shock Testing, Climatic and Environmental Testing, Static and Dynamic Measurement.
With the full backing of LDS, Mr. Kang decided to take the risk of starting his own company. Of his decision he says, “It was a combination of time, opportunity and destiny”. GU has now been running successfully for ten years and has had a turnover of US$ 6 million annually. Mr. Kang says, “There was very rapid sales growth for the first five years, but of course the potential for shaker sales is limited. The life of a shaker is 15 to 25 years, so in addition to new sales opportunities, the company focuses extensively on service and repair, customer support and customer training. We hold more than 10 training seminars a year”.
Customer Support Engineer Mr. Chang-Hoon Lee says, “Our laboratory now has three shakers. We can also provide vibration testing under controlled climactic conditions and currently the lab is used more than 100 days a year”.
Repair and service form 15% of GU’s sales and they provide this for other makes of shakers. Simon Kang explains, “A major part of our work, in addition to the outright sale, is to provide installation including utilities, foundations, even extending to design and construction of buildings”. He continues, “In fact, more than 60% of shaker sales actually request such services and that includes the provision of climactic chambers for durability testing”.
In the last 10 years, GU has sold more than 250 shakers. Simon says, “Customers contemplating the purchase of a shaker are sensitive to both price and quality and applications can range from shaking of packaging to high-level applications such as aerospace and defence including satellite testing”.
