Ensuring Aerospace Fastener Quality with In-House Processes
There’s quality and then there’s quality, and in the world of aerospace fasteners, it’s not something to be taken lightly. Because of their critical role in the function and safety of aircraft, aerospace fasteners must adhere to strict standards. That’s why our aerospace fasteners are not only in-house manufactured, but also in-house tested and 100% traceable from raw material to finished product. Today we would like to give you a glimpse of the complicated process our aerospace fasteners undergo prior to shipment.
Tooling Aerospace Fasteners
The process of acquiring the machines and manufacturing components needed for production is called tooling. Tooling, also known as machine tooling, Common categories of tooling include cutting equipment, gauges, jigs, and fixtures. Our state-of-the-art facility includes the following equipment:
• Forging Presses
• Thread Rolling Machines
• Grinding Machines
• Drilling Machines
• Warm Heading Machines
Aging / Heat Treating
Aging, also called artificial aging or heat treating, is the treatment of a metal alloy at high temperatures to accelerate changes to its chemical properties. Aging can improve coercivity and strength and ensure accuracy and quality in aerospace fasteners’ close tolerance specifications. By doing aging in-house, Aerospace Manufacturing can create high strength, close tolerance aerospace fasteners with significantly reduced lead times.
Electroplating is a process that uses electric current to change the properties of a metal. Electroplating can change or improve the mechanic, electric, and even the aesthetic appearance of a metal. For our purposes, the mechanic changes electroplating achieves are most important. Electroplating improves our fasteners’ abrasion and corrosion resistance as well as the coefficient of friction or sliding friction – essential for all screws and fasteners. At AMI, we have a 6,000 square foot facility dedicated exclusively to electroplating for cadmium, cadmium fluoborate, and passivation.
