How Does Progressive Die Stamping Compare to the Competition?

Progressive Die Stamping vs. Other Common Metal Stamping Methods

Progressive die stamping, compound die stamping, and transfer die stamping are the three most common metal stamping methods. With varying tolerance requirements, design elements, and production sizes required by each application, it is often the case that one of these metal stamping processes offers a superior solution for a particular project.

At Ohio Valley Manufacturing, our team has extensive experience in metal stamping, and we can guide you to the best stamping process to best fit your needs. Let’s take a closer look at when to use progressive stamping, compound stamping, or transfer stamping. 

Progressive Die Stamping

Progressive die stamping is ideal for long production runs because of its ability to achieve high repeatability. This metal stamping process uses one machine with multiple die stations. A metal strip of stock material automatically moves through each station where a stamping operation is applied. The last step cuts the completed part free from the strip. 

Progressive stamping has a lower setup time. Setting up the metal strip requires careful attention to ensure the accuracy of the finished products. Progressive die stamping automatically and continuously feeds material into the machine, allowing for longer production runs, as well as the production of more parts in less time. Therefore, progressive die stamping is ideal for the fast and affordable production of complex components with high part-to-part repeatability.

Benefits of Progressive Die Stamping

  •   Faster production time
  •   Low setup time
  •   Lower labor costs
  •   Minimal scrap 

Compound Die Stamping

Compound die stamping is ideal for medium- and high-volume production of flat parts. The compound stamping process feeds a metal strip through a compound die that performs all cutting, bending, and punching operations in a single stroke. The one-stroke process is good for flat metal parts, like wheel blanks and 1st operation blanks for any application. The production time of this stamping process varies, as it is dependent on the size of the component being produced. Smaller and less complicated parts will finish more quickly than larger parts and parts with more complex design elements. 

Benefits of Compound Die Stamping

  •   Cost-effective
  •   Ensures high repeatability in single-die cases
  •   Quick and accurate production of simple parts

Transfer Die Stamping

Unlike progressive die stamping, the first step of transfer die stamping is to separate the workpiece from the metal strip. Transfer die stamping is typically used for large parts that can’t easily move through die stamping stations. The workpiece is transferred automatically between multiple stations, with automation effectively handling the required alignment between processes.

Transfer stamping is best when working with complex design elements. This metal stamping process requires precise execution and high die durability for successful completion. 

Benefits of Transfer Die Stamping

  •   More versatility
  •   Well-suited for producing complex parts
  •   Cost-effective
  •   Good for large parts

Metal Stamping

Metal Stamping

Metal stamping processes facilitate the creation of a variety of customized components from metal sheets or bars. Machinery-driven dies cut and press materials into the desired shape quickly and efficiently, making the process ideal for high volume production runs. With the proper setup, multiple steps can be performed on each component. With metal stamping machinery, materials can be pressed, punched, coined, embossed, bent, blanked, pierced, and notched to meet a broad range of design specifications.

A variety of metals work well in stamping processes. Stainless steel, aluminum, and hot-rolled carbon steel are all commonly used to produce stamped components.

Carbon Steel Stamping

Carbon steel is a highly malleable alloy revered for its strength. Typically, carbon steel contains between 0.8% and 2.11% carbon content. Higher carbon contents create a harder final alloy. However, these harder materials are more brittle and easily break under the repetitive stress of metal stamping and other machining processes. The average carbon steel used in metal stamping contains roughly 1.5% carbon composition. Some alloys may also include trace amounts of chromium, cobalt, nickel, and other metals to customize the metal for a particular purpose.

There are a number of advantages to using carbon steel for metal stamping:

  • Carbon is a cost-effective option for hardening steel.
  • High-carbon steel is an excellent option for manufacturing efficient and reliable cutting tools.
  • Manufacturing tools made with high-carbon steel ease the mechanical manipulation of other production materials.

These metals are frequently used to produce drill bits, woodcutting tools, masonry nails, saws, and other sharp-ended tools in high volumes.

Aluminum Stamping

Aluminum is one of the most abundant naturally occurring metals on the planet. Using aluminum in low-volume metal stamping offers some important advantages for many manufacturers:

  • Lightweight aluminum alloys support the production of high-speed aircraft, trains, and passenger vehicles.
  • Aluminum materials support sustainability efforts by lowering the amount of energy needed to produce and transport parts.
  • Due to its versatility, popularity, and abundance, aluminum is readily available in any amount.

Aluminum stamping also works well in high-volume metal stamping production for items such as beverage cans, hand tools, and flatware.

sheet metal stamping

Blanking Process Overview


Manufacturers use blanking to punch pieces in specific shapes from sheets or strips of raw material. The punched-out piece is called the “blank,” hence the term “blanking.” Blanking is most often performed with tools made from hardened steel or carbide, which work on metals like aluminum, carbon steel, stainless steel, and even plastic.

Blanking has many benefits, but manufacturers must take some considerations into account before embarking on a full course of metal blanking. Although this process is a quick and cost-effective way to produce a large number of identical pieces, these punched-out pieces may have burrs or cracks on the edges. However, these drawbacks can be avoided by using high-quality tools, and they can be corrected by post-processing the blanks.

Although blanking sounds simple, this basic option can accommodate many variations. A full overview continues below.

Benefits of Blanking

Machinery used for blanking ranges from simple punches and dies to sophisticated CNC machinery. Blanking equipment can quickly be configured to end product specifications, and the process itself takes little time per part as it involves simply feeding the primary metal stock continuously into the blanking machine.

Because of this, blanking can perform long production runs that require little or no changes to the machinery or base material. The straightforward process also allows you to construct materials to strict tolerances with little part-to-part variation, and technology has become so sophisticated that it can build multiple geometries using a single process.

Furthermore, because the primary metal stock can be reused, blanking can help manufacturing firms reduce their material waste. Due to these benefits, blanking is commonly used to mass produce components for industries such as aerospace and automobile manufacturing. It’s also used for high-volume fabrication of parts for common household appliances.

Differences Between Punching and Blanking

Punching and blanking are often confused with each other since both processes remove pieces from a base sheet of material. Adding to the confusion is the fact that the same terms, punch and die, are used in both operations.

A simple way to remember the difference between the two processes is to note that an alternate term for punching is piercing. Manufacturers sometimes refer to this process as piercing because the desired end product is the pierced sheet of metal, not the metal that’s been punched out of it.

As discussed above, the punched-out slugs created by are the end products of the process, and unused sheet metal is discarded or reused after the slugs have been obtained.

There are many other operations that follow, but differ from, the basic process. Some of these include:

  • Shearing
  • Slitting
  • Lancing
  • Trimming
  • Parting
  • Shaving

No matter the type of hole-punching process used, it will result in quality parts at tight tolerances.

Different Types of Blanking Methods

While the fundamentals of the blanking process are simple, they have many variations, which we describe below:

Compound Die Stamping

This type of blanking is used to precisely manufacture complex steel parts. In this process, workers or automated equipment feed a steel strip through the stamping machine, which punches out a blank every three seconds. This simple, precise, and fast technique enables firms to produce steel components in bulk.

Continuous Strip Blanking

As implied by the name, continuous strip blanking continuously feeds metal substrates through a machine. This allows punching machines to produce uniform end products around the clock, with each product having the same characteristics of those before and after it. This process is a great way to develop coins, bottle caps, and medallions.

Progressive Die Stamping

Progressive die stamping uses coiled strips of thin flat metal as its base material. In this process, progressive die machines sequentially stamp, trim, and bend workpieces to make the finished parts, which exit the machine in conjoined strips. After performing this task, the machine separates individual parts from the strip, which results in the creation of several identical parts.

Square Sheared Blanking

Square sheared blanking is a fine process that uses specialized clamping tools to produce square-edged and contoured blanks. This process is a great way to create panels, casings, and any other component that requires a uniform square shape.


This process combines metal cutting and metal blanking procedures to create highly specialized blanks. When cutoff blanking, manufacturers blank metal sheets and then cut the metal at the sheets, allowing the production of long, flat pieces.

Best Materials to Use When Blanking

Ohio Valley Manufacturing performs blanking on carbon steel, stainless steel, and aluminum. Each material brings unique properties to the process, which we explore below.

Carbon Steel

Metalworkers use carbon steel to make industrial equipment and household tools like knives because of this material’s exceptional strength and hardness. Carbon steel’s hardness varies depending on the amount of carbon present within it, and the higher the carbon content, the harder the alloy is.

Carbon content in carbon steel ranges from 0.8% to 2.11%, and the typical value is about 1.5%. Carbon steel is more cost effective than other materials of comparable hardness, thus making it a popular raw material to use as a substrate.

Stainless Steel

Stainless steel has low carbon content but a large amount of chromium, which ranges from 10% to 30% of the final material. This chromium content makes stainless steel highly resistant to corrosion and heat.

Stainless steel may also incorporate other metals like aluminum, copper, and titanium to enhance various attributes, and even nonmetals like phosphorous and sulfur can be used to improve resistance to certain types of corrosive substances. Stainless steel is thus a versatile alloy that can take on a variety of uses depending on its composition.


Aluminum’s softness and flexibility make it very suitable. In fact, aluminum is the most common metal used to create industrial and household products because of this material’s low cost, ease of extraction, and properties like lightness, durability, and recycling potential.

For these reasons, many applications in the automotive, aerospace, energy, and packaging industries use aluminum in large quantities. Aluminum is a very cost-effective way to produce high volumes of components.

Best Metals for Heavy Gauge Stamping

Best Metals for Heavy Gauge Stamping

Sheet metal sees use in a variety of industries and applications globally. In the automotive and aerospace industries, it oftentimes comprises automobile bodies and airplane wings; the medical sector depends on it for operating and examination tables; construction professionals use it day in and day out to constructive massive components that become a part of buildings.


Simply put, the term “sheet metal” can be used to refer to any piece of metal that’s formed into flat pieces. These pieces can vary in thickness but are typically thin and pliable while maintaining strength and structural integrity. This strength sets them apart from thinner, ductile materials such as foils.


In the United States, sheet metal thickness is measured by gauge. This is in contrast to much of the rest of the world, where millimeters are frequently used. Gauge measurements are non-linear. Sheet metal gauge measurements work backward when compared to traditional measurements—the higher the gauge number, the thinner the metal.


The gauge measurement originated during the industrial revolution and is determined by a number of factors. Gauge factors in a metal’s weight and the number of draws that were performed on it. Each drawing reduces diameter, which is why more drawings equal a higher gauge equals a thinner sheet.

Common Metals Used for Heavy Gauge Stamping

Heavy gauge stamping is a specialized term used to refer to metal stamping that uses a raw material possessing an above average thickness. The heavy gauge stamping process requires a stamping press that offers higher tonnage than traditional machines.


The process of stamping thin metals has become a science in itself. Tests have been created for the purpose of determining factors such as formability and mechanical properties. Dealing with thick metals, however, is still a niche undertaking. Experienced manufacturers know that selecting the proper materials, presses, and lubricant can often be a job-by-job task.


Heavy metal stamping is an essential part of the manufacturing process for countless industries. Sectors that require large, thick components and parts specifically benefit from the capabilities offered by thicker metal and the specialized machinery that produces it. Trucking and railroad equipment, power distribution components, and items for the defense industries all rely heavily on heavy gauge stamping to ensure structural integrity.


Several metals see frequent use for heavy gauge stamping. These include:

  • Hot Rolled Carbon Steel
  • Aluminum
  • Stainless steel
  • Brass
  • Copper
  • Fine silver
  • Gold-filled
  • Pewter
  • Solid gold
  • Sterling silver

A Guide to Robotic Welding

Advantages of Robotic Welding

Robotic welding requires little to no human oversight, boosting the efficiency, accuracy, and safety of the welding process. Using this technique, specially programmed robots both hold the workpiece in place and perform the weld in either partially or fully automated processes.

This differs from machine-assisted, or manual welding, which relies on worker oversight and drives up labor costs and the risk of error. Robotic welding has existed in some form in the U.S. since the 1960s, but it has improved in leaps and bounds over the past few years.

What Are The Advantages of Robotic Welding?

Robotic welding offers faster and more efficient welding processes as its technology improves. Robotic welding achieves highly accurate and repeatable designs and operates with higher throughputs than manual welding. This results in increased profit margins compared with manual welding.

Seven Types of Robotic Welding

  1.     Robotic arc welding creates electric arcs between welding units and metal reacts, heating both sides to their melting points. After this, the metal parts cool and form together, resulting in a strong metallic bond. This process benefits applications that require high accuracy and repeatability, such as car manufacturing.  
  2.     Robotic resistance welding joins metal pieces using an electric current. This current creates high levels of heat, causing a pool of molten metal to form between the two pieces. As the pool cools, the pieces join together. Due to this process’s simplicity, resistance welding is highly economical.
  3.     Robotic spot welding works similarly to resistance welding, except it operates on thinner pieces that resist electric currents. Automotive manufacturers commonly use spot welding to join sheet metal frames on cars.
  4.     Robotic TIG welding uses tungsten electrodes to create arcs between welding units and resists. Because tungsten can’t be consumed, this welding process creates high-quality welds and is the most precise form of welding.
  5.     Robotic MIG welding uses continuously fed welding wires to create quick, efficient welds. This process works best for simple welds, and it’s one of the speediest welding techniques.
  6.     Robotic laser welding creates highly accurate welds using supercharged light particles. This technique benefits applications that rely on highly intricate detailing, including automotive branding, jewelry making, and medical instrument manufacturing. It also performs welds in hard-to-reach places that more traditional welding techniques can’t reach.
  7.     Robotic plasma welding feeds ionized gas through a copper nozzle to produce high temperatures, and it also allows operators to easily control and modify weld temperature and velocity. These attributes make it ideal for building electronics.

Finding the Right Fuel to Power American Industry

At Ohio Valley, like many businesses, we like to keep tabs on the issues that affect our industry interests.  One issue in particular affects an interesting cross-section of industries that we’re involved in, and so we’d like to address it here: the ethanol debate.

A concern for both the farming and transportation industries, the ethanol fuel debate has many on edge, especially as a result of the EPA’s November call for a cut in ethanol requirements for gasoline in 2014.  The basic idea is this: in an attempt to cut down on greenhouse gas emissions, corn-based biofuel known as ethanol can be blended into fuel that will burn properly in most motors produced since 2001.  There are different “blend levels” known as E15 (15% ethanol) and the more ambitious, but less widespread E85 (85% ethanol).  Since ethanol and traditional fuel burn differently, the transition from one source to the other would be gradual by necessity, with the interim requiring motors that are capable of burning fuels of different blends equally as well.

The tension comes from farmers who benefit by producing more corn, and big oil, which benefits from producing more oil.  Some think the solution is to promote the E85 option more aggressively, others advocate for offering both fuels and allowing the consumers to dictate demand.  Whatever the outcome for refiners and farmers, the fuel sources for our nation will likely continue to be debated – and not just between ethanol and oil.  Other renewable options like hydrogen, solar, and electricity are all being explored to various degrees of success, perhaps most notably by companies like Tesla, whose electric cars are gaining popularity.

Whatever the energy future, we’re sure farming and transportation needs will continue to endure, and we’ll be here to provide quality manufacturing services for farming and transportation vehicles alike, no matter what fuel source they use to get around.

Lightweighting in Vehicle Manufacturing

One of the biggest buzzwords currently in the motor vehicle manufacturing industry is “lightweighting”.  This refers to the attempt by auto and truck design and manufacturing companies to come up with the lightest weight vehicles possible, in order to be as fuel efficient as possible.  There are many schools of thought as to the best approach for lighter vehicles – in the auto industry, many companies are substituting aluminum, carbon fiber, and other composites to try to save weight and maintain durability.  Designers are scrutinizing every piece of the vehicles, from the frame to the engine, for new and innovative ways to make lighter parts but still provide the same loadbearing and safety capabilities as heavier vehicles.

For the trucking industry, alternate materials aren’t as much an option because of the need to bear higher loads, at higher tolerances.  This means that many are using higher grade steels, with higher tensile strength – but at thinner gauges.  Stronger steel, however, is tougher to manipulate.  The higher grade the steel, the more pounds of force need to be behind the machine that makes the part, and many designs call for steel that is stretching the boundaries of what many manufacturers are capable of.  Fortunately for us at Ohio Valley, our specialty is in heavy gauge stamping, and our 4000 ton press can handle what most others can’t.

As designs call for stronger steel gauges, and the lightweighting trend continues, Ohio Valley Manufacturing will be ready to accommodate our customers with their heavy gauge stamping needs.  Make sure to check back here at our blog for more insight into how this trend is affecting the agricultural and construction industries, or in the meantime, feel free to share your thoughts and get in touch with us on social media.

How PRAXIS Improves Our Processes

At Ohio Valley manufacturing, we are constantly on the lookout for new ways to innovate, optimize, and streamline our business and our customer service.  Back in 2011, we implemented one of our greatest strategies to accomplishing these goals, and we’d like to take some time to explain just how valuable it is for our business and our customers.

The previous problem was this: all of our business functions and transactions, including shipping, receiving, inventory, production, job scheduling, maintenance scheduling, and more were tracked and sorted separately.  The time and resources spent managing all of these various processes and schedules was an area we chose to focus on streamlining.

Enter PRAXIS, our proprietary software that is a powerful tracking and reporting database and workflow package.  It encompasses both MRP functions for inventory control, and ERP functions for streamlined flow of information between departments, and easy resource and production tracking.  PRAXIS was designed in-house, which means that not only are we experts at its use, but it is also entirely customizable.  PRAXIS is fully integrated with all of our machines, and provides real-time traceability for all of our processes, and also tracks AQP reporting, die reviews, and EDI processing.  It offers our customers the option for barcode labeling and shipment notifications via text, email, or ASN, and offers Ohio Valley a solid advantage over our competition.  With a central database from which to monitor all of our internal processes, and that capability to customize and grow with our business, PRAXIS is one of our prouder achievements, and another demonstration of how we seek to build our business in a way that helps us streamline our process so we can streamline our service.
