Metal stamping, also known as metal pressing, is one of the most commonly used metal forming techniques – easily surpassing forging, sand casting, and rolled and welded methods. Stamping involves placing a metal material – usually sheet metal – into a stamping press where a tool and die apply high pressures to form the metal into a final shape.
There are three basic types of metal stamping techniques—progressive die metal stamping, deep drawn stamping, and multi-slide metal stamping. Each method has a unique set of features and benefits which make them ideal for producing cost-effective metal components with a high degree of accuracy across a wide variety of industries.
Metal Stamping by Industry
For decades, the medical and pharmaceutical industries have relied on metal stamping technologies to manufacture a variety of parts and components. Medical equipment has changed significantly over the years, evolving over the past century or more from crudely forged items to complex and intricately shaped tools and devices. Furthermore, modern medical standards and regulations constantly demand more reliable, precise, and sanitary tools.
Metal stamping is used to manufacture tools from a variety of medically approved metals within tight surgical tolerances. Some of the most commonly stamped items in the medical field include:
- Temperature sensing probes
- Dental laser surgical devices
Electronics are notorious for their small and complex parts. Metal stamping is capable of creating these miniature parts with a level of precision that would otherwise be unachievable by most other metal forming techniques. Metal springs, clips, terminals, fittings, ferrules, and contacts are all examples of electronic components manufactured by metal stamping.
The automotive industry is perhaps more reliant on metal stamping than any other. Almost every part of a motor vehicle is stamped as increasing competition has driven the demand for productivity improvements and cost reductions. Fenders, bonnets, deck lids, doors, and trunk panels are some just a few of the stamped parts contained in a typical automobile. Deep drawn metal stamping is also used to make other smaller components such as exhaust mufflers, engineer mounts, pins, and connectors.
The use of metal stamping extends beyond the manufacture of industrial components. Household appliances often contain several small parts such as terminals, brackets, bushings, inserts, washers, and heat sinks. Multi-slide stamping is commonly used to create the sharp bends which often make up these intricate shapes.
Parts in the aerospace industry are required to be built to some of the tightest tolerances and strictest regulations. There is little room for error as each component is crucial for flight safety and comfort. The precision and flexibility of metal stamping are ideal for manufacturing parts that meet the stringent standards of the aerospace industry. Additionally, metal stamping processes are compatible with the various types of specialty alloys often used in this industry, such as steel, titanium, and aluminum alloys.
The versatility of metal stamping is evident in its ability to manufacture countless types of metal parts. Its precision, minimum waste production, high repeatability, fast turnaround, and cost-effectiveness has made this technique the method of choice for most industries.
