At APM, we offer comprehensive engineering and design services including consulting, design, research and development, visual prototypes, working prototypes, and engineering analysis. We partner with our customers all the way through the product development process: from a sketch or model to material selection to final design and working prototype, we have the experience and knowledge to help our customers develop a quality product. Our experienced engineering and fabrication teams can provide either visual or working prototypes of our customers’ products that can be used for design verification, trade show displays, and experimental models. We also offer a full range of engineering analysis testing including, failure, fatigue, flow, rigidity, shock, stress, strain, and finite element analysis, and test to all applicable AS, NAS, and Mil-Spec standards. Our machine shop is very experienced and can meet close work tolerances as tight as ±.0002".

PM was asked to create a hydraulic fluid filter and distribution manifold kits for maintenance use on commercial airlines. We came through for this customer by producing a complex assembly using our engineering, precision machining and finishing services. These kits would need to be manufactured to high standards of quality due to their role in the maintenance of an airliner�s hydraulic control system. Our work started with engineering and the selection of high strength 4130 alloy steel for the kit. To preserve accuracy in the fabrication process, CNC machining methods includied milling, turning, drilling, deep drilling, threading, porting and finishing. Our equipment included a CNC turning center, a CNC vertical machining center and an automatic saw. This combination of cutting-edge methods and high quality material allowed us to achieve tolerances of ± 0.001� on the 6.25� x 1.90� x 1.50� part. Subsequent electroless nickel plating provided an excellent finish and rust protection. Production of each kit was followed by a thorough dimensional inspection that incorporated thread and port gages. Orders of 25 � 50 pieces were delivered with 4 to 6 week lead times. Through our high accuracy production and an engineering team capable of processing highly complex designs, APM delivered this durable, reliable and high performance product.
