CNC Machined Steel Manifold

Challenge Engineering fabricated two types of precision stainless steel spacer samples for us according to the specifications we provided. Both samples were made according to specification in a timely manner with a superb finish. Challenge Engineering assisted with transitioning our designs into cost effective manufacture and exceeded our expectations in every way, thinking of everything, including a female thread chamfer to assure gap-free installation in our product. Great service which exceeded my expectations. Thanks Challenge Engineering!
