Metal stamping is a manufacturing process that mainly processes and produces small to large-sized parts for sheet metal. Metal stamping service is a versatile, high-speed manufacturing process that produces precise metal components in high volumes. Also known as press working, it works by pressing sheet metal between specialized dies using a stamping press machine. Metal stamping offers many benefits that make it an efficient, economical choice for fabricating metal parts and products:

The automated nature of stamping enables very high rates of production. Modern stamping presses can operate at speeds over strokes per minute, producing hundreds of thousands of stamped parts per day. Multi-station progressive stamping operations maximize throughput. The high speed and output of stamping outpace processes like CNC machining.
Metal stamping is highly cost-effective compared to machining or casting processes, especially for high production volumes. The high hourly output keeps per-part costs very low. After initial die design and build, incremental part costs are just raw material, electricity, and press maintenance. No expensive skilled labor is required. The cost of Stamping aluminum parts is around five times cheaper than CNC machining.
Nearly any 2D part profile drawn in CAD software can be stamped, providing enormous design freedom. Modern die design tools and wire EDM allow precision machining for complex profiles. Parts integrating multiple cutouts, forms, beads, and embosses can be stamped in one hit. Flexible tooling modifications enable design revisions.
Stamping materials use virtually any sheet metal material, including steel, stainless steel, aluminum, copper, brass, etc. Many exotic alloys used in aerospace can also be stamped. Unlike casting and forging, material changeovers are fast, not requiring melted metal. Blank dimensions are adjusted to accommodate different material gauges and strengths.
Stamping presses produce highly consistent, precise parts within tight tolerances of +/- 0.005 inches when adequately set up. Modern stamping controls micro-adjust ram position, speed, and tonnage during the stroke to optimize production quality. The stability of the process simplifies inspection. Rejected parts are less than 1%.
The grain flow and work hardening of stamping create components more vital than those made by machining or casting. During stamping, deformation aligns the metal's grain structure along the part contours. It improves mechanical properties like yield strength. Dimensional stability is also excellent.
Metal stamping production lines achieve highly efficient automation. Handling systems automatically feed sheet metal coils into precision blanking presses to cut blanks. Robotic arms then efficiently shuttle these blanks between progressive stamping stations and finishing operations. Automation maximizes output with minimal direct labor.
Soft prototype tooling produced through 3D printing allows concept stamping tools to be created in days versus weeks for conventional complex tooling. Designs can be quickly evaluated and iterated before committing to complete complex tooling. It allows accelerated product development, testing, and refinement.
The nesting capabilities of modern blanking die to maximize material utilization from sheet metal coils. Blanks are optimally nested to minimize skeleton scrap waste. Any remaining scrap can be easily recycled. Unlike milling, waterjet, or laser cutting, no material is wasted during stamping.
Once tooling is proven out, stamped parts show minimal variability over millions of cycles thanks to the stability and repeatability of the stamping process. Statistical process control continuously verifies critical dimensions to maintain tight tolerances during production runs. Consistency lowers quality control costs.
As product volumes increase, additional stamping presses and operations can be cost-effectively added to the production line. The modular nature of stamping equipment allows production capacity to scale efficiently. Both manual-fed and fully automated systems are expandable.
By designing parts suitably for stamping, the need for additional machining, drilling, tapping, deburring, or finishing after stamping can be minimized or avoided. It reduces costs and lead times. Required secondary operations can often be built into the progressive stamping line.
Stamping presses range from small 5 ton benchtop units to massive 4,000 ton presses for automotive body panels and aircraft wings. This wide range means stamping can produce tiny micro-electronics parts to large panels up to 30 feet long. Specialized tooling configurations support virtually any part size.
In summary, the productivity, precision, flexibility, strength, and economy of metal stamping make it an ideal choice for mass-producing components out of sheet metal cost-effectively. It brings significant advantages to any manufacturer needing high-volume fabrication.
"As an engineer, I've used over a dozen metal fabricators over the years, but none match the quality and precision of Neway's laser cutting. Their advanced 3kw fiber lasers produce perfect cuts with minimal kerf every time. Their ability to hold extremely tight tolerances, I'm thoroughly impressed with their ability, even on complex internal cutouts. My projects always succeed thanks to Neway's accuracy and expertise." - John S., Aerospace Engineer.

However, knowing whether metal stamping solutions will provide your business with the ideal products requires a greater understanding. Let’s explore.
Metal stamping is a metal fabrication and manufacturing process that uses indentation to form various shapes, letters and patterns onto sheet metal materials.
Also known as “pressing”, some common and complex metal forming techniques associated with metal stamping include the following:
These metal stamping manufacturing processes and techniques are specifically selected and applied for specialist fabrication requirements across multiple industries and global markets, such as automotive, aerospace, and construction.
The first attempts at metal stamping date back to the stamping of coins in the seventh century. Since metal stamping has continued to evolve and modernise with the times. The metal stamping industry now involves intricate and sophisticated technological advances, such as CNC (Computer-numerical control) and CAD (Computer-aided design) capabilities.
The metal stamping process involves placing cold sheet metal into a machine known as a “stamping press” or “powder press”. A metal die gets applied with immense pressure to push into the material and form the desired shape.
After the initial stamping process is applied, the material can proceed to undergo further treatments, such as trimming, blanking, embossing, etc.
The metal stamping machine literally punches the shape from the surrounding material.
tting out the desired shape from the flat sheet metal material.Also known as “Pewter work”, embossing involves creating raised and shallow features onto the material.
Coining involves indenting a pattern onto the material through compression. The name “coining” stems from the item metal stamping was first used to create.
Bending involves shaping the sheet metal in one direction. Often this process is repeated to create a specific shape.

Like bending, flanging involves moving the sheet metal in one direction but along a curved edge.
Typically followed by further processing, blanking involves cutting out the desired shape from the flat sheet metal material.
So, now we have a core understanding of metal stamping and various processes, let’s take a look at the advantages and disadvantages.
When we consider the mass production of metal parts and products, accuracy and consistency are crucial to upkeep expectations while delivering quality to your consumer.
Due to the automation properties of CNC and CAD, metal stamping provides an efficient and accurate fabrication process to deliver precise parts for numerous purposes, including medical equipment and automotive components.
