Hwashin America is reinvesting in Greenville. The Tier 1 chassis and body parts supplier to Hyundai Motor Manufacturing in Hope Hull and Kia Motor Manufacturing in Georgia announced Monday it would build a 120,000 square-foot addition to its $100 million facility in Greenville, an expansion that will add 100 jobs to the company’s payroll.

Hwashin currently employs 400 people.

“Just imagine what our economy would be like without Hwashin America,” said Mayor Dexter McLendon at Monday night’s city council meeting. “Hwashin is making a new commitment to our community and it’s a great opportunity for the people here. 100 new jobs means so much in the current economy.”

Company officials said the expansion represents a $17 million investment and will house new equipment to support both Kia and Hyundai.

“Hwashin is proud of the success that its customers are enjoying,” the company said in a released statement. “We are making great automobiles and it is showing in the public’s increasing confidence in the projects that we are producing. Hwashin America Corporation believes its team members are the key ingredient to their success and that they play a vital role in the process by building quality in the product…we are all very optimistic and excited about the future of our business and the direction that our company is going.”

Construction will start immediately, said company officials. The new facility should be operational by either April or May 2011, they said.
