The Evolution of High-Pressure Die Casting: Mid-19th Century to Today

Since its inception, the high-pressure die casting process has experienced substantial advancements, evolving from a primitive process into a contemporary, highly efficient, and technologically advanced manufacturing method. The growth and progress of die casting helped improve the competitiveness of various industries ranging from automotive and aerospace to electronics and consumer goods.

In this blog, we will explore the journey of die casting, from its humble beginnings to the cutting-edge techniques used today.

The Birth of Die Casting

Die casting’s origins can be traced back to the mid-19th century when it was first developed to produce printing typefaces. This early process involved manually pouring molten metal into a reusable die. The dies were typically made of iron or bronze, and the process was labor-intensive, slow, and unsuitable for mass production.

The Advent of Cold-Chamber Die Casting

The limitations of this early gravity poured die casting process, including the inability to use high-melting-point metals like aluminum and reduced die life due to the corrosive effects of molten zinc and lead, led to the development of cold-chamber die casting in the early 20th century. In this method, the molten metal is ladled into a separate chamber before being injected into the die. This innovation allowed for a more comprehensive range of metals and alloys and improved safety for workers.

The Rise of High-Pressure Die Casting

As technology advanced, the die casting process evolved further with the emergence of high-pressure die casting (HPDC). This technique employs hydraulic or mechanical pressure to inject molten metal into the die at significantly higher speeds and pressures. HPDC enables the production of thinner and more intricate parts with improved mechanical properties. Aluminum, magnesium, and zinc alloys are commonly used in HPDC due to their fluidity, high strength-to-weight ratios, and stability.

The Influence of Computer-Aided Design (CAD) and Simulation Technology

In the modern era, computer-aided design (CAD) and simulation software have played a pivotal role in the die casting process. Engineers can now design complex dies and simulate the casting process to identify potential issues and optimize designs before production begins. This technology reduces the development time, minimizes material wastage, and ensures better final product quality.

Automation Then vs. Now

The mid-20th century saw a significant shift in die casting with the introduction of automated systems. These advancements allowed for greater consistency, speed, and cost-effectiveness in production. Automatic machines became capable of producing complex parts with high precision at a high rate of speed.

In the 21st century, we have integrated advanced robotic systems into the die casting processes – streamlining operations and significantly reducing manual labor. These automated systems excel in tasks like metal injection and part extraction, ensuring a higher consistency and quality in the final products. Additionally, integrating intelligent technologies and real-time monitoring systems allows for better control over the production line, enabling quick adjustments and minimizing downtime. As a result, die casting operations today benefit from increased productivity, cost-effectiveness, and the ability to meet the growing demand for complex and high-precision components in various industries.

Die Casting vs. Sand Casting – What’s the Difference?

Die casting and sand casting are two popular methods for manufacturing metal parts. While both methods involve casting liquid metal in a mold to create a product or part, there are significant differences between the two processes.

What is Die Casting?

Die casting is a manufacturing process that involves injecting molten metal into a complex, highly engineered multi-component steel mold, or “die,” that is set in a machine that controls the clamping, metal injection, die opening, part ejection/extraction, die cooling and lubrication processes. Die casting can be used with various metals, including aluminummagnesium, and zinc. Each metal has unique properties and benefits (learn about them here) and is suitable for countless applications.

Die casting uses sophisticated hydraulics to inject molten metal with tremendous speed and pressure into the steel die. The machines can apply hundreds of tons of locking force to hold the die shut during metal injection. The water-cooled die extracts the heat, causing the metal to solidify quickly – this process can run up to 100 cycles or more per hour. The machine then opens the die. The part is automatically ejected and (typically) placed into a trim die where the excess material is sheared away, leaving a near-net-shaped part. In some die casting processes, “in die” de-gating separates the excess material from the part, resulting in a shape part produced directly from the casting process.

Automated systems then cool and lubricate the die surface after each cycle.

What is Sand Casting?

Sand casting is a metal casting process that uses sand as the mold material to create parts. This process is best suited for low-volume production.

Molten metal is poured into the cavity through a sprue channel. The metal fills the cavity and takes on the shape of the part. Once the metal has cooled and solidified, the sand mold is broken apart to reveal the casting. Excess material is then removed from the casting by band sawing and grinding.  

Advantages of Die Casting

Here are some benefits of die casting over sand casting:

  • Precision: Die casting produces parts with tighter tolerances, thinner walls, and lower draft, resulting in less secondary machining than sand casting.
  • Surface finish: Die casting provides a smoother surface finish than sand casting.
  • Efficiency: Die casting is a faster and more efficient process that results in lower part costs.

While sand casting has advantages for certain applications, die casting allows for faster production rates, lower labor costs, and the ability to produce more complex shapes and thinner walls – making it a popular choice for high-volume applications.

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. Still, the benefits are that parts can be converted from raw material to finished parts 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 parts in seconds.

High-volume production is also the most efficient way to quickly turn around a large order of parts or products, allowing products to get to market faster and 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. When employing state-of-the-art machinery and a skilled team, today’s manufacturers can produce thousands of units daily, if not more.

Modern high-volume die casting uses 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 having an experienced team around you is crucial 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 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 likely the right choice if the design is three-dimensional and not quickly stamped or extruded.
  • Is the design optimized and stable?
    • To maximize the payback from the tooling investment, optimizing the design and ensuring it is relatively stable before building tooling is crucial, as making changes to tooling after it is constructed can be expensive.

Partnering with the Right Die Caster

Suppose you think your part is eligible for high-pressure die casting. In that case, it’s vital to seek out a reputable die caster with enough experience to guide you through 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, offer 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.

When you collaborate with a die caster who utilizes this state-of-the-art technology, your part is manufactured efficiently over the entire product lifecycle—that’s why having a team of experts to work with you throughout the process is essential.

Chicago White Metal remains very proactive in researching and implementing 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 to improve and enhance quality, efficiency, and measurability. This ultimately leads to overall efficiency for existing and future projects. The team is always excited about taking an original idea and watching it grow into a reality.

One idea that came to life in 2021 is implementing robotics and automation technology in the CNC department. There are currently six 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 to keep up with the equipment maintenance and wiring.

The Fanuc Robot Cells are dedicated to 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 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 have sensors that detect when someone is near or approaching the robot, triggering the mechanism that slows down and stops the machine. This safety feature reassures the team members about the company’s commitment to their well-being.  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 whether the part fits High-Pressure Die Casting. Some of these factors include:

  • Part specifications: The size and scope of your project are among the first things considered — what size is it? What are the physical and cosmetic requirements?
  • Material: At CWM, we cast three alloys: AluminumMagnesium, and Zinc. Each has advantages; 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 proper 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, whether it will be exposed to environmental extremes or chemicals, what other processes are being considered, etc., 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 proper manufacturing process for your part, CWM will initiate the 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 under consideration?

CWM welcomes video conferences throughout the process and encourages face-to-face meetings on-site. We can also 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 and 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 various 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 always completing a mold flow analysis using Magmasoft® to ensure quality casting.

In the preliminary stages of moving from concept to ready-to-tool design, a CWM product engineer will explore the best solutions for the part, including 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 application 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.
