The Benefits of High-Volume Production in Die Casting

CWM building logo
Chicago White Metal’s High Pressure Die Casting process is the perfect solution for high-volume manufacturing projects – especially if you are concerned with cost, efficiency, repeatability, and producing high-quality parts. High-volume manufacturing, via the high-pressure die casting process, involves an investment in tooling, but the benefits are that parts can be converted from raw material to finished part very quickly, with minimal part-to-part variation and significant cost savings. Because manufacturers can produce parts more efficiently, high-volume production decreases the cost of production per unit. In the case of high-pressure die casting, parts can be converted from raw material to finished part in seconds.
High-volume production is also the most efficient way to turn around a large order of parts or products in a short amount of time, allowing products to get to market faster and for organizations to stay on the leading edge of innovation. In a competitive economy where companies continually introduce new items, the time and money saved with high-volume production can set an organization up for success.

Past vs. Present

In the past, a manufacturer might have only been able to produce a small number of parts per day. Machinery advancements enabled output to increase. For example, the first documented use of the die casting process was in the mid-19th century. It involved manually pouring molten metal into a die that opened and closed using a primitive machine. Today’s manufacturers, when employing state-of-the-art machinery and a skilled team, can produce thousands of units per day, if not more.

Modern high-volume die casting takes advantage of automation, including robotics, sophisticated controls, camera systems, sensors, and other technical advancements. These innovations offer many benefits, including repeatability, higher quality products, and lower (and more predictable) long-term costs of operation. However, successfully scaling to high-volume manufacturing requires foresight and planning to streamline the production process and minimize changes.

Scaling – Best Practices

Scaling up a product from the prototype or low-volume production stage (such as a machined part) to a high-volume manufacturing environment (such as high-pressure die casting) can be one of the most exciting stages of the production process. The decisions made during this transition will have significant implications for all aspects of a product, from tooling and manufacturing process control, to packaging and user documentation. That’s why it’s crucial to have an experienced team around you to help guide you through the process.

Here are some questions to ask yourself before considering scaling up to a high-volume manufacturing process such as high-pressure die casting:

  • Are you confident you’ll need enough parts to justify the tooling investment required for high-pressure die casting?
    • The typical quantity for high-pressure die casting is 5,000 pieces per year for several years (often much higher). There are exceptions, but the higher the volume, the more likely the high-pressure die casting process would be the right choice for your product.
  • Will the alloy offered by the die caster be suitable for your application?
    • Some of the more common die casting alloys include A380 aluminum, AZ91D magnesium, and Zinc #3.
    • Ferrous alloys are not an option for high-pressure die casting.
  • Is your design appropriate for high-pressure die casting?
    • Die casting is more likely to be the right choice if the design is three-dimensional and not easily stamped or extruded.
  • Is the design optimized and stable?
    • In order to maximize the payback from the tooling investment, it’s crucial to optimize the design and be sure that it is relatively stable before building tooling, as making changes to tooling after it is constructed can be expensive.

Partnering with the Right Die Caster

If you think your part is eligible for high-pressure die casting, it’s vital to seek out a reputable die caster who has enough experience to guide you through the process of selecting an appropriate alloy, optimizing the design, building robust high-quality tooling, and developing an optimized set of processing parameters. There are numerous areas where an experienced die caster can help your organization ramp up to higher-volume production.

Engineering Design Services, for example, offers tremendous value to the customer because the greatest opportunity for cost savings comes in the design phase before the tooling is built. As part of their design service, CWM uses sophisticated modeling and simulation tools such as Magmasoft and SolidWorks – a solid modeling computer-aided design and engineering application – to help design parts and tooling of the highest quality and lowest cost.

CWM’s Recycling Program – Above and Beyond

CWM’s Recycling Program – Above and Beyond

Chicago White Metal’s environmental practices began long before cultural demands for sustainability started. Reduce, Reuse, Recycle has always been the mantra throughout our operations and supply chain. In both our plant and office operations, recycling comes first.

One of the main reasons CWM maintains such a rigorous recycling program is due in large part to employee dedication. The recycling program has expanded year-to-year thanks to Senior Management’s commitment to excellence in all aspects of the business, especially when it comes to environmentalism.

Recently, Tom Mrock, CWM’s New Product Finishing Manager, took the time to meet with all CWM employees to refresh them on what is and isn’t appropriate for recycling. Tom also educated everyone about “Plastic Free July,” which CWM looks forward to participating in this year. Small steps like that can make a big difference in protecting the environment and maintaining our reputation as an industry leader. 

CWM’s Environmental Policy & Recycling Program

Chicago White Metal is committed to protecting and preserving the environment in everything we do – from recycling scrap metal to something as small as putting the right paper or plastic into the correct recycling bin. We strive to be recognized by our customers, employees, and community as a responsible business committed to evolving our practices to meet the ever-growing demand for environmental sustainability.

As we continue developing our environmentally responsible culture, CWM consistently refines our Recycling Initiatives to focus on environmentally friendly manufacturing principles and general waste reduction. Not only do we hope to reduce our carbon footprint, but also one of our main objectives is to encourage suppliers, neighbors, and customers to adopt similar programs so they can do the same – after all, we’re all in this together.

CWM Invests in Robotics and Automation

FANUC CNC Robot die casting
FANUC CNC Robot die casting

Chicago White Metal remains very proactive in the research and implementation of advanced technology into the die casting process, added value and finishing operations. CWM leadership encourages an environment where team members can examine and suggest alternatives to current techniques in order to improve and enhance quality, efficiency and measurability.  This ultimately leads to an overall efficiency for existing and future projects.  The team is always excited at the prospect of taking an original idea and watching it grow into a reality.

One idea that came to life in 2021 is the implementation of robotics and automation technology in the CNC department. There are currently 6 active robot implementations: 4 Universal Co-bots and 2 Fanuc Robot Cells.  These robots were commissioned quickly in the past 12 months, calling for the promotion of Daniel Lechuga to Automation Specialist in order to keep up with the equipment maintenance and wiring.

The Fanuc Robot Cells are dedicated to several tasks such as facilitating added value and finishing operation checks, leak testing several parts at a time, and tending to CNC machinery.  This allows team members to tend to other machines and focus on performing more critical tasks.  The Fanuc robots were the first to be integrated into the CNC department and can be seen on the shop floor with cages around them.  They are currently facilitating parts for an archery riser and an automotive ECU housing.

The Universal Co-bots are collaborative robots that work safely alongside humans.  The robots themselves have sensors that detect when someone is near or approaching the robot, triggering the mechanism which slows down and stops the machine.  Chicago White Metal implemented four co-bots, which are currently handling parts for two different models of portable oxygen concentrators, a crossbow riser, an electronic housing, and a medical device handle.

Importance of Design for Manufacturing in Die Casting

Before the Design for Manufacturing (DFM) process can begin, it’s essential to determine which manufacturing process will be the optimal solution for your final product. While several methods are available to manufacture parts efficiently, few offer the quality, environmental advantages, and cost savings of die casting.

Depending on the project’s specific needs, our team will work with a potential customer to determine if the part is a good fit for High-Pressure Die Casting. Some of these factors include:

  • Part specifications: The size and scope of your project are one of the first things taken into consideration – what size is it? What are the physical and cosmetic requirements?
  • Material: At CWM, we cast three alloys – Aluminum, Magnesium, and Zinc. Each has its own set of advantages, and our team can help determine which alloy might be the ideal choice for your component.
  • Project details: It is essential to provide as much detail as possible about your project to determine whether die casting is the right process for the application. Information such as the expected annual and lifetime quantity needed, where the part will be assembled, what mating parts are attached to it, will it be exposed to environmental extremes or chemicals, what other processes are being considered, etc. These are all important details to help determine if high-pressure die casting is a good fit.

Application Review

Once it’s determined that die casting is the right manufacturing process for your part, CWM will initiate DFM process with your team. It starts with a detailed application review – the more we know about your project, the better prepared we will be to make recommendations.

Our engineers must understand what the end product does and how the part being cast will function. Even the most minor details may affect cost and performance. Therefore, CWM’s engineers consider the following factors in the initial review:

  • Mating part review: What components or materials connect to this part? Where are the connecting surfaces?
  • Function: What are the features and functions of the part?
  • Product testing: Are there any additional tests the part needs to undergo (i.e., leak testing, stress tests, corrosion resistance)?
  • Finishing: Are there any cosmetic or finish requirements? What surfaces does the user view? What coating is being considered?

CWM welcomes video conferences throughout the process and encourages face-to-face meetings on-site at CWM, or we can arrange for our team to visit your location. A visit to CWM will allow both our team and your team to develop a partnership, review best practices, learn about the die casting process & other technologies used at CWM, and discuss the plans for the future.

Part Optimization

At CWM, a DFM review is part of every new project. As part of that review, we offer our customers a wide variety of design assistance. For example, we will work with you and your team to complete design conversions from injection-molded parts, other casting methods, or hogouts. Our team also assists with recommendations for appropriate design guidelines for all three alloy types, consolidating assembly components into a single die casting, and we always complete a mold flow analysis using Magmasoft® to ensure a quality casting.

In the preliminary stages of moving from concept to ready-to-tool design, a CWM product engineer will explore solutions that would be best for the part – this can include weight reduction or component consolidation. Then, CWM can work with your team through various designs until the part is optimized for our High-Pressure Die Casting process and your applications requirements.

We believe that a well-optimized part makes for an improved die cast process that can ultimately reduce part cost – which, aside from producing the best quality part possible, is the primary goal.

Equipment Highlight: CWM’s new 1000-Ton Die Casting Machine

In September of 2020, Chicago White Metal’s maintenance team took on the task of installing a brand new aluminum 1000-ton die casting machine. Under the leadership of Max Golovin, CWM’s Director of R&D, the installation of a new IDRA-900 Xpress Die Casting Machine was completed in the spring of 2021. CWM produced the first official casting from the new machine on March 24, 2021.

The purchase of the IDRA Xpress 900 Series Die Casting Machine gives CWM the ability to expand our already extensive capabilities. Bill Erbacci, CWM’s Customer Care/Fulfillment Manager, said, “The new IDRA machine gives CWM increased capacity and scheduling flexibility. As a result, CWM can run a broader mix of parts in the new IDRA. This translates into shorter die casting lead times for our customer’s orders.”

Benefits of the IDRA Xpress 900

The IDRA Xpress 900 Series Die Casting Machine features a state-of-the-art design with a 900 Metric (1000 US) ton clamping force capacity and a larger platen than other CWM machines. In addition, the Xpress Series from IDRA offers a Rigid Toggle System, which gives the machine the closing force necessary to produce larger, thin wall, complex parts.

The Xpress Series from IDRA was an ideal choice for CWM because it offers excellent efficiency and long-lasting precision – it also provides:

  • Fast and reliable injection of the molten metal
  • Longevity, because it’s built to last in heavy-duty conditions
  • Easy maintenance
  • Low energy consumption
  • Full automation

One of the most significant benefits of adding the IDRA Xpress 900 Series Die Casting Cell to CWM’s fleet of equipment is that it is a complete Die Casting Cell. Meaning, it’s equipped with its own melting furnace, two robots, an automatic sprayer, hot-oil heating units, water-cooling system, part cooling conveyor, and trim press. One robot loads ingots into the furnace, while the other extracts the part from the die and places it on the conveyer.

What the Future Holds

CWM has already produced many parts in the new machine, and the results have been excellent. The IDRA Xpress 900 Series Die Casting Machine allows CWM to push the boundaries because we can now produce larger parts while still maintaining the highest quality possible.

Equipment Highlight: FANUC Robots

Benefits of using Robots

At Chicago White Metal Casting, we strive to have the most advanced technologies available to assist with die casting, CNC machining, and other operations. For example, CWM has two FANUC robots in our CNC department – the M10iA and the M-20iB. The M-10/20 series robots offer increased load capacity and extended reach. These robots are small, but they are the perfect automation solution for many applications, especially when it comes to handling, assembly, material removal, and machine tending.

In addition to its increased load capacity and reach, the M-10/20 series robots use considerably less energy than older models; they also boast a cost-efficient modular design. Furthermore, the M-10/20 series robots offer integrated cable routing, making them considerably easier to maintain – ultimately saving time and money.

Robot Use at CWM

At CWM, we use the FANUC M-10/20 series robots to load/unload the CNC machining center for some of CWM’s higher volume parts. The robots that CWM employs can work with several different part numbers and utilizes camera-based vision systems to accomplish the following:

  • Verify the presence and location of holes
  • Determine the orientation of the part
  • Load and unload parts onto a CNC fixture
  • Install special clamping inserts
  • Confirm the clamping is correct
  • Sequence part unloading/loading from conveyor

One of the most significant advantages of utilizing these robots is that several hours’ worth of material can be loaded/unloaded into side-by-side input/output conveyors integrated into the cell and tied into the robot’s logic. This system allows the robot/CNC cell to work continuously, resulting in a steady flow of parts. In addition, the robot incorporates several camera-based inspection steps using a 2D vision verification system that stimulates the eyes, further assuring that parts will meet CWM’s and the customer’s quality standards.

Why Did CWM Choose FANUC?

The FANUC M-10/20 robots are designed for various light material handling applications. They are considered high-speed robots and can be used in many scenarios, including assembly, CNC machine tending, and even in the die casting process. In addition, this robot simplifies applications and floor plans because it is more compact than other robots while maintaining the highest axis speeds and best repeatability. 

Another benefit of using these robots is they can be mounted at any angle on the floor, wall, or ceiling. They are also very small, which means they can fit into tight workspaces. At Chicago White Metal, we currently have six active robots in our CNC department – four universal co-bots and two FANUC Robot Cells. Co-bots, or collaborative robots, are different from robots because they can work with humans to accomplish tasks while robots work independently and run with no human intervention.

How CWM Assures Critical Cosmetic Success

At Chicago White Metal, we are constantly investing in advanced technologies to improve the die casting process. While Magmasoft® has been used in the industry for years, it’s still considered a revolutionary technology because it reduces lead time, improves quality assurance, and saves money. The engineering team at Chicago White Metal has been using Magmasoft® software for a little over a decade, and it’s made a big difference when it comes to producing quality castings. 

There are numerous projects that have seen success at CWM thanks in large part to  Magmasoft® and the hard work of our engineering team. Recently, CWM was given the opportunity to cast a magnesium housing for a handheld camera. The combination of the part specifications and the shape meant it would be challenging to create an optimum part. 

After our engineering team created the tooling design for the project, they used the advanced Magmasoft® process simulation software. Doing so enabled the CWM engineers to predict the effects of the final metal flow for the part. After a series of precise tooling design iterations and repeat simulations, the design was released for die tooling construction—the final result: a strong, well-cast part.

This is a good example of the metal flow simulation provided by the Magmasoft® software.

As illustrated in the animation above, Magmasoft® allows rapid analysis of a product’s design, tooling, and process variables before die construction. Magmasoft® is designed specifically for metal casting manufacturers. The advanced software provides incredibly realistic and detailed mapping of all involved processes.

CWM engineers believe that the Magmasoft® system is the best predictor of a die casting die design’s performance. It provides the best estimate of the metal flow results that can be expected in the final cast part.

Contact CWM today to learn more about Magmasoft® and how it can help reduce lead time, improve quality assurance, and lower manufacturing costs. You can also request a quote from our sales team to see if your project is suitable for die casting.

Equipment Highlight: Investment in Energy-Efficient Furnace Pays Off

energySMART Aluminum Furnace

Chicago White Metal is always looking for ways to improve the die casting process while decreasing energy usage. Back in 2014, CWM determined that one of the best ways to accomplish both of those goals was to replace our old reverberatory furnace from the 1970s with a modern central stackmelter aluminum furnace.

CWM worked with energySMART, a Nicor Gas program, to replace our underperforming furnace with a high-efficiency one. After much deliberation, CWM chose the StrikoMelter furnace from StrikoWestofen America because it offered the lowest energy consumption of any furnace in its class.

Energy Efficiency & Improved Performance

When CWM chose the StrikoWestofen energy-efficient aluminum melting furnace, we immediately received energySMART incentives in return for reducing our carbon footprint. With the new furnace, CWM cut the amount of natural gas we used in the melting process substantially. And even though the StikoMelter came with a smaller holding capacity, the melting capacity significantly increased to 4,400 lbs. per hour instead of 1,400 lbs. per hour with the old furnace.

By acquiring the modern furnace, CWM qualified for the Nicor Gas Energy Efficiency Program, an energy-purchase rebate program funded by Nicor Gas Company. The incentives from this program enabled CWM to make the investment, which saw immediate returns.

How it works:

The new furnace came with Striko’s patented ETAmax® system, which combines preheating, heating, and melting phases efficiently in a single melting shaft. While return material and ingots are melted quickly in the lower section, the material preheats in the shaft area above it.

The molten metal is then transferred to a holding bath, reducing waste and maintaining preset holding temperature. This simple but effective recuperative concept resulted in significant fuel consumption savings and a dramatic reduction in metal loss due to oxidation or dross. Other benefits of having a modern, energy-efficient furnace include:

  • Easy to load: The furnace’s shaft is more expansive and can easily accept returns of up to 2.5m². Extra-large charging bins also mean there’s no need to “cut to fit,” saving precious time, resources, and money.
  • Less energy wasted: Shortened metal melting, reduced natural gas consumption, and an improved material yield to increase efficiency.
  • Cleaner metal: The design of the furnace limits the amount of dross and oxide production resulting in cleaner metal and less waste.

Looking back almost seven years to the date, we can say that it was well worth the investment when it comes to energy savings and improving CWM’s overall product. When asked about the furnace, Jim Reitenbach, Production Manager at CWM, said, “This was one of the best equipment investments CWM has ever made.”
