Precision and high standards are hallmarks of the aerospace industry. With so much at stake with each flight, there is no room for error. The slightest mistake can lead to substantial financial loss, or even worse, fatal injury. Manufacturers who produce the parts for aerospace are held to a very high standard and are heavily scrutinized as they conduct their business. Metal stamping services are perhaps one of the most notable aspects of aerospace manufacturing.
The metal stamping process involves transforming flat metal sheets into specific shapes. Metal forming can involve a number of techniques, including punching, bending, and piercing, among others. This intricate process can make small components, like fasteners and screws, for the aerospace industry.
Deep-drawn metal stamping is a variation of metal stamping in which flat sheets of metal are drawn into a die to form components. As the name implies, deep draw stamping involves components with greater depth than width. With each successive die drawing, the width of the component decreases as the length increases. It’s also common to deep draw components in parts to create different diameters. Compared to turned parts, which require more material, this process is more cost-effective.
There are several methodologies used in the stamping process. With such a broad list of strategies, you can easily customize your product to fit your project’s requirements. Here are some common metal stamping methods:
Beading: Reducing or enlarging the diameter of a part by displacing the material.
Bottom Piercing: Cutting a round or shaped section of metal from a drawn component.
Bulging: Forcefully extending part of the diameter of the component from the original shape.
Coining: Displacing material to form specific shapes in the component.
Curling: Rolling metal under curling die to create a rolled edge.
Extruding: A large diameter punch is used to push through a pilot hole and extend the metal.
Ironing: The process of thinning the walls of components.
Necking: Taking a section of a component and making it smaller than the rest of the component.
Notching: Making a notch in the open end of the part.
Rib Forming: Rib forming is the process of creating an outward or inward protruding rib on the part.
Side Piercing: Piercing holes in the sidewall of the drawn component. The shape is dependent on the component’s specifications.
Stamping: A method of adding identification to the part, such as the name of the supplier or a product number.
Threading: Creating threads with a wheel and arbor.
Trimming: Removing metal that was necessary for drawing the part from the finished part.
Anchor bolts, self-tapping screws, cotter pins, shims, and castle nuts are among the fasteners used in the aerospace industry. To create these customized pieces, deep-drawn stamping is a great method. The process allows for accuracy, customization, and versatility. Aerospace Stamping Materials
It is always very important to use the right material in aerospace applications. Choosing the right material is crucial to success. This is a shortlist of metals that can be stamped using this process:
Aluminum 6061- Lightweight, strong, corrosion-resistant, and weldable.
Titanium- Extremely strong and lightweight, corrosion-resistant, and heat-resistant.
Waspaloy- Resistant to high temperatures, corrosion from oil-based products, and overheating & frequent thermal cycling.
Inconel- resistant to high temperatures and highly tensile.
Due to their ability to resist high-temperature extremes and maintain resistance against deformation, Waspaloy and Inconel are two of the most commonly used super-alloys in the aerospace industry. The high stresses that aerospace construction requires makes them a perfect choice.
