ATech Designs, Inc. (formerly Innovative Engineering, Inc.) was founded in 1998 by Karl R. Leinsing in Raleigh, NC. The company consisted of offices in Raleigh, NC and a manufacturing plant in Charlotte, NC. In 2002, the company moved to Hampton, NH and became ATech Designs, Inc. in 2005 and then moved to a larger nicer facility in Dover, NH in 2013.

Quality…from start to finish

Quality products result from our sound business practices. We like to start with a complete list of requirements or specifications for a product. We then analyze the market, obtain data on current technology, and perform benchmark testing on current products, if available. We then come up with ideas to solve the problem, perform a patent search on ideas, and patent any new ideas. We then develop the ideas into a new product. We thoroughly test the product and deliver a final product that is well documented with every detail required to duplicate the product and process.
