Quality Control Processes & Certifications
Our AS9100 REV C certified procedures treat all raw materials with the same flow. Raw material can be in any form from assembly standards, customer supplied, customer direct ship, or P&J purchased. All incoming materials are inspected to the source requirement and identified with a code allowing onsite recognition of material. We use and Alpha-numerical system labeled directly on the product in multiple locations i.e. CS-XXXXX located multiple locations, on container and material both ends (as applicable) CS= Customer Supplied-next numerical number in sequence. This material code is used to trace raw materials throughout production and is labeled on EVERY production plan used to make product, including non-aerospace.
Manufacturing and custom machining starts with our MRP software. E2 Shoptech is being utilized at PnJ. This coordinates all of our Departments efforts to supply product on time at a competitive price. E2 allows digital links of drawings, shop set up sheets or any digital data to share information through out the company. Each CNC machining center at P&J has a E2 terminal for accessing digital data and bar coding operational sequences. When changes to digital data are conducted they are viewed live in our shop within minutes of the change. Drawing revisions, set-up sheet revision, or planning changes are communicated thru the company while all departments are conducting normal job processes.
Manufacturing planning sequence operations are labeled utilizing customer specifications by name ensuring employees use the current revision of any standard or specification. Manufacturing digital set up sheets contain pictures and descriptions including CNC program revision listed to coordinate proper set up. Inspection sequenced operations are required after every production operation ensuring quality products are being produced at every planned operation.
P&J currently outsources plating or special processes with a broad support base of suppliers who are NADCAP or customer approved sources. All plating or special processes are verified by inspection, upon acceptance, and then routed to the customer or assembly kit.
Assembly / Final Inspection:
Assembly of product at P&J custom machining ranges from simple nutplate installation to Electrical Continuity Tested ground studs, per BAC5117 (applicable section). Our Mapholder/Approach Plate part families have 60 standards/components assembled by P&J. These are located on the Yoke of the airplane. Bushing installation utilizes Liquid Nitrogen to shrink fit the bushing per BAC5435. Bearing installation in any method from anvil staking, ball staking, Roller swage sleeve, to list the most common. P&J is capable of conducting any method required. All required instructions are required to be listed in the Manufacturing Planning which is followed by PnJ employees.
All products, irrelevant of complexity, go through Final Inspection, verifying all pervious operations were conducted to the Manufacturing Planning or specification requirements. Verification of planned operations being accepted are required to have shop stamp or inspection stamp as objective evidence of completed operations. Customer certification packets are gathered for distribution at time of shipment.

P&J Machining Inc. Quality System is registered in OASIS data based and audits were conducted by BSI. Since July 07 PnJ has been AS9100/ISO9001 certified. The history of our system dates back to Boeing D1-8000, D1-9000, and D6-82479 Appendix A to today's standard AS9100 REV C.
The Planning Department and Document Control is managed by Quality Manager giving further control over P&J's Quality Management System. PnJ believes having the highest level of the Quality Department involved in Planning is important to minimizing complex layering of drawing, specification or standard requirements being implemented into sequences that are understood and distributed to employees via the Manufacturing Planning.
P&J's Zeiss CMM gives us the technology to prevent bottle necking in our Inspection area based on our Cell Systems output. When our cell systems came online, our total Inspection inputs increased but we were able to maintain with minimal bottle necking. When we purchased our 2nd cell we purchased a CMM to ensure our QC Department would be able to handle the new volume of parts. The CMM increased our turn around time and efficiency. As our library of programmed parts increases we expect this to become increasingly more
