Adept Corp. has tripled its manufacturing space with a 40,000-square-foot addition to its plant in York.
Adept invested more than $1 million in the expansion. The company added another extrusion line and has room for at least five more, said sales manager Richard Altland in a June 1 telephone interview.
``Our product line has really expanded greatly,'' he said. ``We were bursting at the seams.''
York-based Adept will increase its workforce by 10-15 percent, he said.
Adept was founded in 1966 as a window fabricator and supplier of tooling and special machinery. It entered the plastics business in 1991, when it began producing PVC extrusion tooling.
The company manufactures window accessory parts, architectural flower boxes and profiles for plastic swimming pools.
The company also makes a line of standard metal product stampings, stamping dies and assembly equipment for the vinyl window industry.
In 2006, Adept was No. 16 of the 50 fastest-growing companies in central Pennsylvania, said Altland.
The company has doubled its output and sales during the past four years, he said.
``Metal stampings - in the past, that has been the mainstay of our business,'' Altland said. ``That's now been overshadowed by plastic extrusion. Now that's 75 percent of our business.''
Adept had sales of $8.4 million in 2006.
