Basics of Metal Stamping

Types of Stamping Materials

Tools for Stamping

Stamping — also called pressing — involves placing flat sheet metal, in either coil or blank form, into a stamping press. In the press, a tool and die surface form the metal into the desired shape. Punching, blanking, bending, coining, embossing, and flanging are all stamping techniques used to shape the metal.

Before the material can be formed, stamping professionals must design the tooling via CAD/CAM engineering technology. These designs must be as precise as possible to ensure each punch and bend maintains proper clearance and, therefore, optimal part quality. A single tool 3D model can contain hundreds of parts, so the design process is often quite complex and time-consuming.

Once the tool’s design is established, a manufacturer can use a variety of machining, grinding, wire EDM and other manufacturing services to complete its production.

Aluminum Stampings – cost-efficient with lightweight properties and a high strength-to-weight ratio. Its usage includes building components, aircraft and aerospace components, marine hardware, electronic chassis, and countless other uses.

Stainless Steel Stampings – high corrosion resistance and high strength. Due to its hygienic properties, it is used for food-grade, pharmaceutical, also aerospace, transportation, and medical applications.

Steel Stampings – versatile due to its exceptional malleability and ductility. It is beneficial for automotive applications, various structural components, and building components.

Copper stampings - Copper, and related alloys, offer outstanding electrical conductivity, high thermal conductivity, good corrosion resistance and machinability. As today’s world becomes more electrified these materials are crucial in manufacturing buss bars, switchgear, and other current handling component parts.

There are several steps in producing metal stamping. The first step is designing and manufacturing the actual tool used to create the product.

Let’s take a look at how this initial Mould is created: Stock Strip Layout & Design: A designer uses is used to design the strip and determine dimensions, tolerances, feed direction, scrap minimization and more.

Tool Steel and Die Set Machining: CNC ensures a higher level of precision and repeatability for even the most complex dies. Equipment like 5-axis CNC mills and wire EDM machines can cut through hardened tool steels with extremely tight tolerances.

Secondary Processing: Heat treating is applied to metal parts to enhance their strength and make them more durable for their application. Grinding is used to finish parts requiring high surface quality and dimension accuracy.

WHAT IS A STAMPED FIN HEATSINK?

Cost-efficient stamped heat sinks enhance heat transfer for circuit board components by increasing surface area. For maximum design flexibility, a Stamped Fin Heatsink can be stamped into a broad range of geometries and thicknesses. The Stamped Fin Heatsink Technique offers a good approach for producing high efficiency, high aspect ratio, lightweight heatsinks in small package sizes, and is a good choice for medium to high volume production. This technique also offers a low Non Recurring engineering charge, so prototype set up costs are minimal.

An Aluminum Stamped Finned Heatsink can be manufactured using the A6063 Aluminum alloy which produces a high thermal conductivity of ~200 W/(m-K). The Copper Stamped Fin Heatsink is typically manufactured using C1100 which produces a very high thermal conductivity of ~400 W/(m-K).
