  1. What’s the Difference Between Tool and Die?

    Comments Off on What’s the Difference Between Tool and Die?

    The terms “tool” and “die” are used interchangeably to the point that many machinists refer to the field broadly as “tool and die”, regardless of their specific expertise. In general, this practice is completely appropriate—there is little functional difference between a tool and a die, if any, and most machinists who fabricate tools also create dies. However, there are some nuances to the terms in industry, so it’s worth breaking down the slight distinctions.

    tool and die

    The easiest way to think of the difference between a tool and a die is simply that dies are a subset of tools—all dies are tools, but not all tools are dies. In metal stamping, a tool can be almost any mechanical device used to cut, form, support, or mold metals. By that definition, jigs and fixtures are tools, as are drills and cutting blades. Dies, on the other hand, are only those tools that functionally change the shape of the metal. Dies are typically the female components of a larger tool or press.

    Even more confusing, many industry stakeholders will also refer to the male partner of a female die component as a die. In this common usage, the punch block is called a die, as is the punch or press, but structural components like fixtures are still tools. Still others consider any tool containing a die to be a die itself.

    Working under the second framework, where a die is considered to be both the male and female forming parts, it becomes more useful to classify dies by function rather than to debate the somewhat nebulous distinction between terms.

    Die Types

    There is a wide dictionary of terms used to classify dies, some broader than others. At the highest level, dies can be separated by their function of either cutting or forming the stock material. Any die that removes, cuts, or shears material can be called a cutting die, regardless of its mechanism, while a die that doesn’t remove anything is a forming die. 


    This classification is a bit of an oversimplification, as some dies do combine cutting and forming functions. It’s also possible to go further with these types of groupings—considering coining dies separate from forming ones, for instance—but those distinctions are based on the process itself and can be seen as somewhat redundant. 

    Another useful way to classify dies is to consider what happens with each stroke of the press as a portion of the whole tooling process.

    Read blog: Progressive Die vs. Transfer Die vs. Compound Die Stamping

    Simple Dies

    A simple die, as its name suggests, only performs one cutting or forming action per stroke. These specialized machines can be cost-effective for simple designs, but they are far less efficient where multiple forming actions are necessary.

    Compound Dies

    Compound dies are designed so that a single stroke accomplishes multiple cutting and forming actions. Although combining operations can slow down the stroke, compound dies are more efficient over the course of the tool manufacturing process and minimize the chance of errors when transferring a workpiece between multiple stations.  These dies are generally less costly than progressive dies.

    Progressive Dies

    Progressive dies offer one of the most efficient methods of accomplishing multiple operations on a single blank. Rather than performing operations simultaneously, however, the modifications occur at separate stations as a feeding mechanism continuously pushes metal into the die. 
    In this way, each stroke initiates multiple cutting or forming actions, but they are applied to different segments of the workpiece—each of which will become its own finished component. The final station removes a finished component from the longer workpiece, meaning that each stroke yields one or more parts even as others are in process.

    Transfer Dies

    Transfer dies resemble progressive dies, but they begin with pre-cut blanks that must be mechanically transferred between stations rather than using one continuously-fed strip of metal. Conveyor belts or transfer fingers often provide the transfer action. A transfer die allows for heightened efficiency even when working with larger parts or more complex parts that aren’t compatible with progressive die cutting.

    Multiple Dies

    A gang press or multiple die press is unique in that it creates multiple components with every stroke of the press. Typically, this requires several identical dies to be linked to the same control mechanism so that they can operate in sync with one another.

    Parts of a Die

    Though there are differences across categories—especially between cutting and forming dies—most dies consist of a similar set of components:

    parts of a tool

    • Die block. The die block is comparable to a mold in that it has holes and indentations that correspond to the desired shape of the component. The punch or press depresses the piece into the die block to achieve the desired shape. In most cases, this is the female portion of the die.
    • Die holder. A die holder supports the die block, and the holder itself is supported by a bolster plate. These pieces are attached to the upper or lower die shoe.
    • Punch plate. The punch plate attaches the actual punching component to the ram, which propels its movement.
    • Punch. The punch is the male portion of the die which actually descends onto the workpiece to force a conformational change.
    • Stripper plate. The stripper plate helps separate the workpiece from the punch after each stroke.
    • Guide pin. Guide pins are essential to precisely align the upper and lower halves of a die. 
    • Pressure plates/back-up plates. Various pressure plates are installed in the die to distribute the extreme pressure applied by the punch. 

    parts of an upper die parts of a lower die

    Difference Between Male and Female Dies

    We’ve repeatedly referred to male and female dies, but it can be helpful to clarify exactly what that means—especially since dies show so much diversity. 

    As in electronics, the male component is the protruding component, while the female is the depression or indentation.

    • — In the context of metal stamping, the male punch is driven into the die block to cut or form the workpiece (or both, as discussed above).
    • — The corresponding female part defines the shape of the component and includes the die block indentations into which the workpiece is pressed. The female portion is not always composed of solid cavities, however, and holes can be useful to allow sheared or drilled metal to be cleared easily.

    Except in instances where the operation uses only a simple die, the male portion will likely comprise multiple steel cutting or forming punches with the female portions matching the male pattern.

  3. Manufacturing of the Future: ESI Speeds Up Production With 3 New Machines

    Comments Off on Manufacturing of the Future: ESI Speeds Up Production With 3 New Machines

    There has been a lot of speculation lately about the future of manufacturing. What will be the top trends? How will manufacturing’s contribution to the GDP change? How will jobs shift as technology becomes “smarter”?

    Speeds Up Production

    It’s difficult to definitively answer these questions. But one thing is for sure: the manufacturing renaissance is here, and it is sweeping the industry. Technologies like 3D printing have been commercialized, and equipment embedded with sensors can now “communicate” with each other using the Internet of Things (IoT).

    The availability of data for strategic planning, the rise automated machines, and a slew of other exciting advances are allowing manufacturers to produce units faster, smarter, and leaner than ever before.

    At Engineering Specialities Inc., (ESI), unmatched production efficiency isn’t a luxury; it’s how we do business. Recently, we added three new top-of-the-line machines to speed up production times, allowing us to get solutions to our clients faster and more efficiently than ever.

    Wire Straightening Machine: Producing Defect-Free Items, Faster

    Commitment to quality is of paramount importance in any manufacturing endeavor. But deadlines must be adhered to as well. ESI’s team helps customers contend with difficult turnaround times and urgent needs. In a bid to expedite part production even further, we have added a fully enclosed and integrated wire straightening and cutting machine to our equipment line-up.

    This machine takes round or shaped wire off a coil, straightens the wire to eliminate irregularities such as bends, and cuts it to the precisely desired length for inherently defect-free items — all in one go for better quality at a faster turnaround.

    Automated Packaging Machine: Reducing Time to Ship by a Quarter

    ESI is proud to offer end-to-end manufacturing solutions that include quality assurance, inspection, and assembly services. Proper packaging is a key component in this sequence, and manual execution is no longer efficient or effective.

    This is why we have switched over to a sophisticated automated packaging system that does the work of 20 hours in just five.

    This new packaging machine first unfolds the boxes, then loads the parts, weighs them, and packages them according to their weight. Finally, the boxes are wrapped with a pallet wrapping machine, allowing us to deliver products faster and at lower prices.

    New Metal Stamping Press: A Single Tool for Many Industries

    We’ve also introduced a 45-ton stamping press that is versatile enough to serve the progressive die stamping needs of a whole slew of industries and applications, including automotive, aerospace, medical, lighting, specialty plumbing, industrial hardware locks, and electrical connectors.

  4. How Is Technology Changing Manufacturing?

    Comments Off on How Is Technology Changing Manufacturing?

    Over the past several years, advanced technology has come to the forefront in the manufacturing world.

    This technology not only enhances processes via automation, it has also allowed for a huge resurgence in U.S. manufacturing. In fact, data from the Institute for Supply Management showed that as of October 2017, the U.S. manufacturing industry had expanded at its fastest pace in 13 years.

    automated technology in manufacturing

    Evolutions in additive manufacturing, automation and industrial robotics are changing every step in the manufacturing process. Manufacturers are adopting robotics and technologies to collaborate with human engineers and operators, freeing them up for higher-level tasks and thereby increasing overall efficiency.

    At ESI, we’re proud to be a part of this exciting shift. We make use of various advanced manufacturing and industrial automation technologies, allowing us to provide cost-efficient, high-quality products with extremely quick turnarounds. Take a look at some of our automated processes below to see just how much time manufacturing technology saves us — and our customers.

    3D Printing

    Time saved for prototyping jobs: Over 200 hours

    3d printer

    The use of 3D printing has dramatically reduced the amount of time needed to develop and produce prototypes, as well as the overall costs associated with the process.

    Before we started utilizing 3D printing, it could take up to two weeks to design and develop a prototype. Additive manufacturing has reduced that time to just three or four hours. And since less time is required to build the prototype, ESI can now devote more time to thoroughly testing and evaluating the part, which, in turn, allows us to more easily adjust and optimize the design as needed.

    Automated Packaging

    Time saved for packaging: 15 hours

    automated-packagingThe team at ESI also makes use of a sophisticated automated packaging machine that loads parts, weighs, and packages them according to weight. With this manufacturing technology, ESI has been able to significantly reduce the overall time and costs needed for all packaging processes.

    What used to take 20 hours with manual packaging now takes just five hours­­. This allows us to get products to customers faster, at lower rates than allowed by manual packaging.

    Vision Inspection/Assembly

    Time saved for inspection: 10 mins. per part (for million-part jobs)

    To ensure our products are of the highest possible quality, we employ an integrated vision inspection and assembly system — a unique, customized assembly machine featuring built-in technology that inspects part runs in the millions.

    This allows for high precision and nearly eliminates the risk of any defects or problems. With this technology, we’ve significantly reduced the amount of time needed to check dozens of specified criteria; now, this complex analysis can be done in just milliseconds. And since this system combines assembly and inspection processes, we can more effectively manufacture large runs of parts with greater accuracy.

    Before we started using this technology, the turnaround time for inspection and assembly was about 10 minutes per part, but now it’s just half a second! Jobs that would have been nearly impossible to complete are now easily doable.

  6. Thinking Green: ESI Supports Environment with Solar Panels

    Leave a Comment

    Solar power usage saving CT manufacturer gas, money, and emissions

    Earth Day is just as important in the manufacturing field as it is in the private realm — especially for local metal stamper Engineering Specialties, Inc. (ESI), which saves one hundred tons of CO2 per year with its building’s solar panels.

    More than two years ago, ESI worked with Independence Solar to install one of the area’s largest photovoltaic solar panel arrays. The completed project, which required a total of 494 solar panels on the roof of ESI’s 30,500-square-foot metal stamping and machining facility, has a maximum power generation capacity of 124 kilowatts (kW).

    “We are happy and excited to be doing our part to reduce our carbon footprint,” said ESI President Ron Delfini. “The energy efficiency we’re achieving is a large aspect of our mission to be a responsible, environmentally-friendly manufacturer.”

    Originally anticipated to fulfill about 65% of ESI’s electrical requirements, the system has been performing above expectations — to date, the system generates an average of 70% of ESI’s requirements.

    In two years, ESI’s solar panel array has generated over 340,000 kW hours (kWh) of electricity. This amounts to a 250-ton reduction in their carbon footprint. To put it another way, the panels’ energy output is the equivalent of over 28,000 gallons of gasoline — enough to drive 50 cars for a year.

    And the solar panels are saving more than just energy.

    “Between energy savings and incentive payments, we generate approximately $41,000 a year,” Delfini said.

    By generating their own electricity, ESI mitigates spikes in energy prices. Keeping a significant operating cost stable allows them to focus on investing in high-end equipment and technology for the benefit of their clients.

    solar-panel-monitoringAs an added bonus, ESI’s solar panel program also benefits the local Connecticut community. On sunny days, any surplus energy not used by the building is fed back into the grid, helping to keep their neighbors’ energy supply stable and affordable.

    ESI’s solar power progress is available online to the public. Numbers, including current and past solar generation, kilowatt hours produced, tons of carbon saved, and more information can be viewed at Live.DeckMonitoring.com/?id=esi.


  7. Cutting Labor Costs with Automated Assembly

    Leave a Comment

    When Henry Ford first introduced the assembly line concept in the early 1900s, it was a serious game-changer — revolutionizing not just the automobile industry, but the entire manufacturing industry virtually overnight.

    custom-assemblyAfter more than a century since Ford’s innovation, the manufacturing landscape is now facing a similar manufacturing revolution: automated assembly.

    Automating certain manufacturing processes, particularly advanced assembly processes, can carry a number of benefits:

    Quicker Turnaround Time

    Smart, efficient use of automation reduces turnaround time for projects. With automation, it is easy to combine a number of assembly capabilities or production steps into a single step. ESI’s custom assembly machine with vision inspection, for example, assembles and compares dozens of part dimensions simultaneously in just seconds.

    See how it works in the video below, or download the case study for the full story.

    This combination of steps not only saves time, but also saves space in a facility. With one piece of automated equipment performing multiple steps, the individual work stations for each of those steps can be eliminated.

    Higher Quality

    Automation also enhances production quality. While some tasks, such as aligned press fits, are often difficult to perform manually, they can be made much more efficiently and accurately through automation. Automated assembly also allows for a high degree of conformity across pieces, another manufacturing aspect that is typically difficult to accomplish manually.

    Further, quality assurance steps can be implemented into an automation system in the same way that multiple production processes can be incorporated. ESI, for example, incorporates cutting edge vision-based inspection technology into all of our automated processes. This allows us to deliver assemblies with virtually 0% defect rates.

    Reduced Labor Costs

    One of the most important benefits of automated assembly is the opportunity for both direct and indirect labor cost savings. Directly, the reduction in cost of labor is clear. Every step that can be automated is a step that an employee no longer has to perform; this frees time for other tasks that can’t be automated.

    However, indirect labor savings achieved through automated assembly are often easily overlooked. Automation can reduce:

    • — Material handling and component orientation time
    • — In-process inventory, when replacing batch operations
    • — Finished product inventory
    • — Scrap
    • — Defective pieces
    • — Personnel training

    All of these reductions help to keep the cost of assembly low, but are often not considered in cost savings calculations.

  10. 3 Ways to Address High-Volume Metal Stamping Defects


    A common need in today’s business and manufacturing world is the production of large quantities of complex parts – with quick and accurate results.

    Finding a cost-effective metal stamper that can meet the required time frame also isn’t easy. There are a few challenges that can slow production time or quality.

    Combatting Defect Rates

    prevent-metal-stamping-defectsDefect rates are one of the most common challenges that come with high-volume runs. These types of runs can incorporate numbers as large as millions or even hundred-millions. With this many parts, inspection of each piece becomes quite challenging.

    ESI’s team created a solution for the high-volume inspection process to help prevent potentially defective parts from reaching the customer.

    Our solution involves using multi-part fixturing that allows multiple parts to be inspected simultaneously. This special inspection method involves coordinate measuring machines, or CMMs, which use a probe to do a tactile inspection of each part, coupled with machine vision systems inspecting parts using imaging software.

    ESI’s multi-part fixtures allow us to measure and compare hundreds of part dimensions in only a few minutes. Not only is the process time-sensitive, it also guarantees quality and fidelity of the parts we manufacture at any size run. This ensures that no defective parts are sent out to valued customers by maintaining quality assurance across all orders.

    Other Challenges

    3-solutions-metal-stampingThe multi-part fixture is simply one solution to various problems associated with metal stamping high-volume runs. Our latest eBook addresses two other challenges commonly faced with such runs, such as when a process does not output the part as it was designed, and when a high-volume production wears down tools, resulting in eventual delays.

    To learn more about potential challenges in high-volume runs of metal stamping, as well as further solutions to these issues, download our free eBook, 3 Solutions to High-Volume Metal Stamping Defects.
