API Precision Machining Inc.

API Precision Machining Inc. was established in 1945 as Commerce Welding and Manufacturing, Inc. This independent machining business was started by Charles S. Hejkal and Clarence Greiving. In 1957, Mr. Hejkal and Mr. Greiving established a 'sister' company, Aircraft Products, Inc. The new company secured contracts with several American and international companies earning a stellar reputation for quality products and customer satisfaction.

In the 1960's, Aircraft Products was honored to be a part of the Saturn/Apollo Program, which fulfilled America's goal of landing a man on the moon. The company was presented with the Supplier Award and was recognized in the Roll of Honor in the Smithsonian Institute. During this time frame, Aircraft Products was also awarded the Boeing Top Supplier Achievement Award.

In the 1980's and 1990's, Aircraft Products became a leader in the telecommunications industry. The company received the E-Systems Supplier Achievement Award, the Rockwell International Top Performance Supplier, and the Alcatel Achievement Award.

Aircraft Products, Inc. soared into the new millennium with the opportunity to be a part of the space program again. We now have machined parts onboard the NASA International Space Station.

In October 2002, ownership of the company was realigned to include a partnership of Mr. Hejkal and his daughter, Karen Hejkal Lynch.
