This is the best information for die stamping on the internet.
Here is what you will learn:
Die stamping, a cold forming technique, starts with a strip of metal, often called a blank or tool steel. Using one or more dies, this process shapes and cuts the metal to create a specific design or profile. The force applied alters the blank's structure and geometry, allowing it to be bent or sculpted into complex shapes. This method can produce metal parts of various sizes, from minuscule to enormous, depending on the application requirements.
Also known as pressing, die stamping includes diverse methods such as blanking, punching, piercing, coining, among other operations. Precision in design is crucial to ensure each punch achieves high-quality results.
Dies used in die stamping are specialized tools crafted to create specific designs, ranging from simple, everyday items to detailed components in electronics. They can function as single-use tools or operate as part of a sequence of stages to perform multiple functions.
(These three processes will be further detailed in Chapter 3: Production Methods).
Stamping dies are essential tools in the metal stamping process, serving two primary functions: cutting and forming. Some advanced stamping dies are designed as combination dies, capable of performing both actions in a single stroke. These die stamping operations allow manufacturers to separate sheet metal or shape it into intricate geometries through controlled plastic deformation. Understanding die stamping operations is critical for those seeking reliable, cost-effective solutions in metal fabrication, automotive manufacturing, appliance production, electronics, and many other industrial applications.
Forming dies manipulate and compress sheet metals into precise shapes, functioning much like stencils to create consistent, repeatable results. These forming operations are vital for industries requiring high-volume production and tight tolerances, such as aerospace, medical devices, and automotive manufacturing.
Bending forms basic and complex geometries—such as L, U, or V profiles—by applying controlled force that plastically deforms the workpiece along a single axis, without exceeding the metal's tensile strength. The bending process is a foundation of metalworking and is commonly used in fabricating brackets, enclosures, and automotive components. Automated CNC press brakes and precision dies ensure repeatable bending angles and part accuracy for a wide range of materials, including stainless steel, aluminum, and copper alloys.
Flanging involves bending the edge of a workpiece along a curved axis. The process features two primary types: stretching and shrinking. Tension and compression forces shape the metal, depending on the length of the flange or tab. Flanging operations are ideal for producing curves, corners, or reinforcing features—often found in the automotive, aerospace, and appliance industries. The method's efficiency and accuracy are well-suited for mass production, with modern stamping presses enabling high-volume output while maintaining dimensional integrity.
Drawing is a precision metal forming process that forces the workpiece material to flow radially while retaining nearly the same surface area. The drawn shape adopts the contour of a die, allowing the transformation of flat sheet metal into cylindrical, box-like, or complex hollow components. Drawing preserves material thickness and provides high strength-to-weight ratios, making it indispensable for manufacturing deep-drawn parts such as beverage cans, sinks, and automotive housings.
One advanced drawing method is deep drawing, where the depth of the draw exceeds the diameter of the part, allowing formation of deep, seamless products. Deep drawing is suitable for a broad spectrum of industries due to its ability to produce precision, leak-proof, and cost-effective components.
Stretch forming, or stretching, relies on tension and thinning to increase the surface area of the metal workpiece. This process creates a smooth surface ideal for painting, coatings, and aesthetically driven products. High-pressure dies tightly grip and stretch the metal, resulting in parts resistant to dents and warping. Stretch forming is commonly used for aerospace skins, automobile panels, appliance housings, and architectural components where surface appearance and uniformity are crucial.
Coining uses intense pressure to permanently deform the metal and imprint patterns or features onto the workpiece's surface, reducing its thickness as desired. This high-precision process enables the creation of intricate details, making it ideal for producing currency, medallions, precision gears, electrical contacts, and decorative hardware. Coining delivers sharp edge definition and outstanding repeatability, important for industries demanding close tolerances and high consistency.
Ironing is similar to coining but is specifically utilized to reduce and standardize wall thickness in cylindrical metal parts, such as cans and battery sleeves. By squeezing the part beyond its original thickness—commonly to 30%—ironing ensures uniform, thin walls and increases the vessel's overall length. Manufacturers use ironing in combination with deep drawing for producing lightweight, robust, and seamless containers in high-speed production environments.
Below is a detailed explanation of cutting dies—essential tools for separating metal in die stamping operations. Cutting, also known as shearing, involves applying force until the metal material fails along a specified line, producing high-precision blanks or profiles.
Blanking removes a portion of a sheet metal strip along a chosen contour to create discrete parts, known as blanks. The cut-out blank is the intended workpiece, which is further processed or assembled. The remaining strip material is typically scrap, though it can sometimes be recycled, optimizing material usage and lowering overall production costs. Blanking operations are key in industries such as automotive, appliance, and electronics manufacturing—anywhere repeatable part geometry is required for assembly lines or further operations like forming and welding.
Shearing creates straight, linear cuts in sheet metal and is widely used for producing rectangular, square, or uniquely-shaped blanks. The shearing process accommodates both parallel and angled cuts, ensuring part accuracy and minimal waste. Routine applications range from cutting plate steel for structural projects to producing custom electrical enclosures for cabinets and panels. Advanced shearing equipment allows for high-speed, automated cutting, vital for maintaining high throughput in stamping operations.
Piercing creates holes or specific internal features in a workpiece using a punch and die set. Unlike blanking—where the cut-out becomes the usable part—in piercing, the punched-out section is scrap while the parent material is retained. The precise sizing and placement of holes or cutouts allow for component assembly, fastener installation, or electrical routing in final products. Piercing operations are crucial in the fabrication of panels, mounting brackets, and electronic housings, where customization and tight tolerances are required.
Trimming is the final cutting step in die stamping, used to remove excess flash or material from the perimeter of a formed part. Trimming ensures that each component achieves its specified profile and clean edge, ready for downstream processes like welding, painting, coating, or assembly. This operation is often automated in mass production lines, improving consistency and minimizing manual labor. Industries such as transportation, HVAC, and home appliances rely on trimming for parts with precise dimensional accuracy and high-quality edges.
Notching is a targeted cutting technique performed on the outside or along the edge of the workpiece, preparing it for further bending or forming operations. Creating notches allows easier cornering, simplifies assembly, or facilitates shaping during secondary processes. Notching is common in the production of metal frames, structural supports, cabinet enclosures, and components requiring precise fitment in their final configuration.
The twelve die stamping operations described above represent only a small sample of the techniques available. Custom metal stamping, progressive die stamping, transfer die stamping, and precision engineering allow manufacturers to address a wide range of complex geometries, tight tolerances, and specialized material requirements. Consulting a qualified die stamping manufacturer or metal fabricator enables you to select the optimal die type and process for your specific needs—improving part consistency, reducing overall cost, and accelerating time-to-market. For critical components, in-depth expertise in die design, material selection, and process engineering is invaluable for achieving the highest standards in metalworking and product manufacturing.
Whether you are researching tooling for a new project or evaluating suppliers for mass production of stamped metal parts, understanding these core die stamping operations will help you make informed decisions, ensuring quality, cost efficiency, and scalability in your manufacturing process.
When selecting a die stamping method, critical factors such as production cost, cycle time, material utilization, and required geometric tolerances all play a vital role. Choosing the right production process impacts not only the quality and consistency of formed metal parts but also overall manufacturing efficiency and profitability. Below, we provide an in-depth overview of the four most common die stamping production types used in the sheet metal fabrication industry: line, transfer, progressive, and compound die stamping.
Line dies are employed primarily for low-volume part production or for manufacturing very large parts that cannot fit on a single press. In this metal stamping process, the workpiece is transferred from one station to the next, with each workstation completing a unique forming or cutting operation. This method provides flexibility for parts with complex geometries and diverse features. Combination dies used in line production can execute multiple forming or blanking operations in a single pressing stroke, helping to reduce handling time for certain applications.
Transfer dies operate in a fashion similar to line dies, but take automation to the next level by synchronizing multiple die stations together. In transfer die stamping, pre-cut blanks or partially formed metal sheets are evenly spaced — a characteristic known as "pitch" — on a press bed. These parts are then automatically transferred between stations along side-by-side rails or moved manually, with each die completing a specific shaping or forming function. Automated transfer systems are ideal for manufacturing large parts with complex features, helping maximize efficiency for medium and high-volume production. After each press cycle, the workpiece is securely gripped and advanced to the next station, ensuring process consistency.
Progressive die stamping is acclaimed for its high automation, productivity, and consistency in producing complex, precision metal parts at scale. In a progressive die set, a continuous strip of metal is fed through a series of stamping stations. Each die in the sequence performs specific operations such as punching, coining, bending, or blanking. The stress applied is distributed evenly over several operations, resulting in precise tolerances and excellent part repeatability. The even spacing of operations is called the progression. Progressive dies are widely used in high-volume production of automotive and electronic components, hardware, and consumer products due to their speed and low per-part cost.
Compound die stamping is a precision metalworking process where strips of material — often steel or other metals — are fed through a compound die set that performs simultaneous cutting or punching operations in a single press stroke. This approach enables quick, efficient production of flat and intricately shaped components, offering exceptionally tight dimensional repeatability for applications like washers, gaskets, and electrical contacts. A knock-out mechanism ejects each completed part as the remainder of the strip moves forward for the next cycle. This rapid stamping technique can reach production rates exceeding 1000 units per hour, minimizing cycle times, labor demands, and lead times.
Because compound die stamping eliminates the need for multiple dies and repeated handling, it reduces overall stamping costs and material waste. The single-die configuration enhances product consistency and ensures superior flatness, which is especially valuable for thin metal components requiring close manufacturing tolerances. Many manufacturers prefer compound die stamping for its ability to streamline operations, lower per-unit costs, and meet the high productivity demands found in modern industrial production environments.
Regardless of the sheet metal stamping process used, proper lubrication is essential to maximize tool life, enhance part quality, and maintain efficient press operation. Lubricants reduce friction between the die and metal workpiece, prevent galling, surface scratching, and overheating, and help provide a hydrodynamic film that improves material flow during forming and punching sequences. Effective lubrication minimizes production defects such as rips, tears, and wrinkles, contributing to lower reject rates and higher yield for precision stamped metal parts.
When punching or forming dies exert force against a metal strip, friction and heat can cause surface defects, excessive die wear, and increased maintenance costs. To counter these issues, manufacturers apply specialized lubricants tailored to their process—forming a protective barrier on the workpiece and tooling surfaces. This lubricating layer is vital in reducing both tool damage and defect rates, particularly when working with stainless steel, aluminum, and complex alloys.
The main industrial lubricant application methods during die stamping are drip, spray, and roller coating, each optimizing coverage based on part geometry and material thickness. The type of lubricant chosen will depend on the specific stamping process, environmental considerations, and final product requirements. Modern lubricants used in metal stamping include compounds made from plant, animal, and mineral oils, as well as graphite, soap-based, acrylic, or fully synthetic, oil-free formulations. For more information on sourcing metal forming lubricants, visit lubricants.
By understanding the strengths, limitations, and ideal applications of each production method—and prioritizing optimal lubrication practices—manufacturers can choose the best die stamping process for their part specifications, production volume, and business objectives.
Die stamping is a cold forming process that shapes, cuts, or forms metal by pressing it with dies. This technique produces parts ranging from small electronic components to large industrial items, using methods like blanking, punching, and coining for precision results.

There are four main types of die stamping presses: mechanical, hydraulic, servo, and pneumatic, named according to the force-generating mechanism they employ. Each type is categorized into C-frame and straight side varieties, where C-frame presses feature three open sides, while straight side presses have two. The ram or slide, where the upper die is mounted to apply force, can have single or double connectors.
The image below shows a straight side press, equipped with four to eight guideways. These guideways enable it to manage off-centered loads effectively while safeguarding against deflections.
Stamping press manufacturers utilize specific terminology to describe the operation of their equipment, with individual companies often employing proprietary terms. Below is a comprehensive diagram listing all the terms associated with a die stamping press.
Below are selected stamping terms from Sutherland Presses Auto Stamping based in Malibu, CA. For a complete list of their die stamping terminology, please visit their website at https://www.sutherlandpresses.com/news/press-terminology
When communicating with a die casting company, it's advantageous to be familiar with the vocabulary to understand the terminology used.
Hydraulic and pneumatic die stamping presses are widely used, with mechanical presses remaining the cornerstone of the industry. Each type of press employs a distinct method to achieve similar functions with varying types of force. Some models integrate both hydraulic and pneumatic methods. Motor presses represent a recent advancement under evaluation and exploration by major manufacturers.
A pneumatic press utilizes air pressure to drive the downward stroke of the ram, while springs facilitate its upward movement. When activated by the controller, air fills the cylinder, expanding to generate pressure. At the end of the cycle, the air is released, allowing the ram to return to its starting position at the top.
Hydraulic presses provide force using static pressure over a finite and small area. They use pressurized incompressible fluid in a cylinder or cylinders to drive the ram. They are used for metal forming, shallow stretching, and bending. There are three parts to a hydraulic press: machine, power system, and control system.
Until recently, the primary method to increase tonnage was by constructing larger motors. However, press manufacturers have now replaced motors, clutches, and flywheels with servomotors. These servomotors provide precise energy delivery at specific locations, enhancing control over the ram.
Servo presses enable operators to program the dwell time at the bottom of each stroke, ensuring the workpiece settles perfectly before forming. This capability significantly extends the lifespan of the die. Additionally, programming the dwell allows for advanced in-die functions, such as pre-heating the metal before forming. This pre-heating prevents tough materials like stainless steel from tearing during deep draws. Moreover, programmable functions facilitate the use of water-soluble lubricants instead of oil-based lubricants, eliminating the time-consuming and environmentally problematic oil-removal step in subsequent processes. These features make servo forming a compelling alternative to mechanical presses.
All mechanical presses produce force by stored energy from a flywheel. Punches can be 5 mm up to 500 mm at stroke speeds of 20 to 1500 spm. They are categorized by their type of drive, which can be single gear, double gear, double action, linked, or eccentric geared.
Energy stored in the flywheel is discharged using one of the drive types. As the flywheel completes each rotation, it gradually loses energy, reducing its speed by 10 to 15 percent per turn. This lost energy is replenished by an electric motor.
Tonnage – They can vary in size from 20 tons to 1600 tons with the ability to supply substantial force.

When selecting a metal for die stamping, several factors should be taken into account, such as its mechanical properties, lubrication requirements, press speed and capacity, magnetic attributes, and the type of steel used in die construction. Die stamping utilizes both ferrous and nonferrous metals, with aluminum being particularly favored for its strength, lightweight nature, and resistance to corrosion.
Two primary considerations must be evaluated when selecting a metal: ductility and tensile strength. Ductility is critical as it determines a metal's ability to be shaped and formed without cracking, tearing, or breaking. Tensile strength, on the other hand, measures a metal's resistance to breaking under tension and pressure. These factors are essential criteria for assessing a metal's suitability for die stamping.
Tensile testing is a straightforward method used to determine how a sample responds under tension, revealing its breaking point when subjected to external forces. These tests provide designers and developers with material analysis reports to predict how a metal will perform in its intended application. The diagram below illustrates the testing process. Tensile strength reports typically include values in megapascals (MPa). For instance, 1090 mild steel has a yield strength of 247 MPa and ultimate tensile strength of 841 MPa, with a density of 7.58. In contrast, aluminum exhibits a yield strength of 241 MPa and ultimate tensile strength of 300 MPa, with a density of 2.7.
Benefits include:
Ductility describes a metal's capacity to deform without fracturing, as depicted in the diagram below.
Four factors contribute to determining a metal's ductility: elongation percentage, tensile strength, yield strength, and hardness.
Elongation percentage measures how much a metal can stretch within a specified distance, typically two inches. For example, a metal with a 38% elongation can stretch 38% of its original length before fracturing when elongated over two inches.
Tensile strength refers to the maximum stress a metal can endure. A higher tensile strength indicates greater ability to withstand stress.
This measure quantifies the force required to shape and deform a metal. When a metal undergoes deformation, it experiences two stages: elastic and plastic. Elastic deformation occurs when it bends under its own weight, whereas plastic deformation involves permanent changes to the metal during processing.
The hardness of a metal is determined using the Rockwell hardness scale, which measures its resistance to penetration by applying weight until the metal surface yields.
Various metals can be utilized in the stamping process, categorized as either ferrous or nonferrous. Ferrous metals contain iron, while nonferrous metals do not. Steel exemplifies a ferrous metal, derived from iron ore, whereas aluminum, devoid of iron, originates from raw aluminum. In general, ferrous metals are magnetic, whereas nonferrous metals are not, with a few exceptions.
Because nonferrous metals lack iron, they are resistant to rust and oxidation. Nonferrous metals commonly used in stamping include aluminum, bronze, brass, gold, silver, tin, and copper. Among these, aluminum is preferred for its strength, lightweight properties, and corrosion resistance.
Of the ferrous metals, steel is the most used in stamping due to its strength and durability.
Because nonferrous metals lack iron, they are resistant to rust and oxidation. Nonferrous metals commonly used in stamping include aluminum, bronze, brass, gold, silver, tin, and copper. Among these, aluminum is preferred for its strength, lightweight properties, and corrosion resistance.
Stainless steel is another type of steel used in stamping, classified as a ferrous metal. The composition of alloys, primarily chromium and nickel, in stainless steel determines its grade. Each grade possesses specific properties and characteristics that make it suitable for diverse applications. For instance, stainless steel grade 316 is ideal for marine applications, whereas grade 304 is preferred for chemical and food processing industries.
Typical grades of stainless steel used for stamping are 301, 302, 304 & 304L, 316 & 316L, 321, 410, and 18-8.
Aluminum, a nonferrous metal utilized in stamping, is valued for its lightweight nature, strength, and resistance to rust and corrosion. Typically, aluminum is alloyed with other metals to enhance its strength and augment specific properties and characteristics.
Aluminum's excellent formability makes it an ideal metal for stamping, as it can be shaped and molded into virtually any configuration.
Copper, similar to aluminum, is a nonferrous metal known for its ease of forming and ability to be shaped into seamless components. It is low maintenance, highly resistant to corrosion, and naturally hygienic, making it suitable for medical, food, and beverage applications. While pure copper is used in stamping, it is often alloyed to improve its durability and strength. Its high ductility makes it well-suited for the stamping process.
Brass is an alloy of copper and zinc, with the proportions of each metal defining its grade and ductility. It features a smooth, silky surface that is easily shaped, resistant to corrosion, and has excellent conductivity. Additionally, brass is chosen for its attractive appearance and superior aesthetic value.
C26000 is among the most widely favored grades of brass, largely owing to its remarkable corrosion resistance. The hardness of brass correlates directly with its zinc content percentage.
Specialty metals encompass a wide range of materials crafted to endure severe environmental conditions without corroding, degrading, or becoming brittle. This category includes diverse titanium and nickel-based alloys. Their extensive variety makes it challenging to generalize their characteristics, as they are specifically engineered to meet precise operational conditions.
Specialty metals commonly share two key attributes: corrosion resistance and heat resistance. Engineering these metals involves enhancing the base material's strength, durability, and resilience against impact and physical damage.
Microstamping involves manufacturing parts that are nearly imperceptible to the naked eye, typically measuring fractions of a millimeter in size. The production of these micro-stamped parts demands highly precise technical procedures with strict tolerances and exceptionally accurate dimensions. These miniature components are created through processes such as line, transfer, or progressive die stamping, where they are pressure-formed at microscopic scales and may include even smaller integrated elements.

Micro lumbar retractor – Micro Lumbar Discectomy at 1.57 in (40 mm).
Micro USB Breakout Board – Breakout board with USB Micro-B connector.
One challenge with the die stamping process is its inflexibility. Once a die is cast or a product is produced, there is limited room for reverse engineering or process corrections. However, new auto simulation software enables designers to conduct simulations in a seamless process, minimizing iterations and validating designs before they proceed to manufacturing.
Simulation software is designed to compute the stages of the die stamping process, aiding developers in anticipating potential flaws and errors in designs, including those outlined below.
Tensile failure can occur due to excessive stitching of metal, resulting in deformation like smiling or elongation caused by stretching the metal to its maximum threshold.
a tear or rip caused by too much stretching; happens after necking.
