About Us


Kettmann Machnining Inc.

Kettmann Machining Incorporated (KMI) was founded by Larry Kettmann in 1983. KMI’s first order was supplying parts as a sub-contractor to other machine shops in the highly competitive high-tech hub of Silicon Valley.
Since the early 1980’s, Kettmann has grown into an invaluable supplier of precision-machined plastic and metal parts to the manufacturing field in the U.S. and for distribution abroad. Since the beginning, our commitment has been 100% customer satisfaction through carefully evolved, leading-edge, quality-driven, lean-manufacturing processes.
