We use AlSi9Cu3 only for some specialized industries. It has robust mechanical properties and is a perfect solution to ultra-lightweight automotive parts.

The materials Sunrise Metal work with for its Low Volume Die Casting production

What are the Applications of Low Volume Die Casting?

We provide low volume die casting services to many international businesses related to different applications. Some of these applications are the following:

What is Low Volume Die Casting Tooling?

Sunrise Metal is experienced in high-yield, durable, and complex custom parts with qualified tolerances for low volume die casting tooling. We provide precise tooling services for low volume die casting. Furthermore, we produce small unit parts of different sizes up to large machines.

We deliver top-quality die-cast tooling through each relative service. With every new requirement and specification, our skilled team finds the best way to facilitate our customers with exceptional quality parts.

Conventional, long-life die casting tooling is costly and sometimes makes it hard for low volume production. These low volume production scenarios require specialized low-volume tooling.

Without productive and innovative thinking, the per-piece costs can increase to the extreme. For example, manufacturing medical and hospital equipment and parts are where low volume production is mostly required for validation purposes.

Sunrise Metal use low volume die casting tooling for cost-effective production. However, our techniques will not let the overall cost increase and most suitable for lower volumes.  Problem-solving is what we are specialized in.

The following are some of the best cost-effective strategies for low volume die casting tooling:

  • Single Cavities: The problem with multi-cavity die-casting molds is that they provide high volume production and expensive. If low volumes are required, a single cavity solution is preferred and is sufficient and significantly reduces mold costs.  The same logic applies to complex die casting parts. Least complex and tools that require single operation help reducing the overall cost.
  • Modular tool design: Use flexible inserts that are easily interchangeable and exchangeable so that they can be swapped in and out of the die set. Most importantly, it’s an incredibly useful approach for scenarios in which parts are required in a range of sizes.
  • Soften tooling: Aluminum is the most preferred material for low volume die casting tooling, and it opens the door to a less hard and durable solution. It will cut time and save money as a result. Aluminum’s thermal properties are essential along the way. And aluminum’s features can cut costs by eliminating the need for cooling galleries.

What is the difference between Low Volume Die Casting vs. Investment Casting?

Die casting is one of the most advanced and oldest manufacturing techniques. However, the necessary die casting process hasn’t changed much. Today’s die casting machines and methods are more advanced and using the latest technology. You can reach your end product or part in many different ways, but the question is, which one is most beneficial and precise?

Low volume die-casting and investment casting are considered as the most similar and standard processes.

The Low Volume Die Casting Process:

Initially, the process starts with melting the alloy. Afterward, the molten alloy is poured into the die cavity made out of steel. When the metal solidifies, it’s carefully ejected from the tool. The same process is repeated for every time until the production requirement is met. This is the general mechanism of die casting, and the process sometimes depends on the material used. Because using Aluminum will give you rapid outputs and decrease the overall low volume die-casting costs.

The Investment Casting Process:

Low volume production using investment casting is typically a more time-consuming and costly process. It starts with manufacturing a prototype. This prototype is made out of wax and copies the exact part. Afterward, the prototype is dipped into liquid ceramic. Then the ceramic hardens, and the wax starts to melt. In the end, it leaves you with a ceramic mold. Afterward, the molten metal is poured into the ceramic cavity where it solidifies. After the whole process is finished, the ceramic mold is crack opened, and the required part is removed carefully.

The mold that was used to make the wax patterns is reusable. However, the ceramic mold that was crack opened is disposed of with each part manufactured. Its complex process and high material usage are way more expensive and time-consuming.


Low volume production projects need to be handled with extreme care. These projects require rapid production, cost-effective solution, and quality outputs. These things only can be achieved through low volume die casting.

At Sunrise Metal, we focus on four essential things while working on low volume die casting projects:

  • The overall production volume
  • Tolerance capabilities
  • Overall cycle time
  • Final part cost

How to know that Low Volume Die Casting is best for your project?

Die casting is one of the oldest known, and its process is simple and powerful. This process can manufacture all types of shapes, including the ones with complex designs. These parts are used in the vast majority of industries, from marine and communication to aerospace and electric. Rather than comparing low volume die-casting with other similar processes, we’ll simply run through some key considerations when it comes to low-volume production.

Our observations and selection depend on the following considerations through which you can know why low volume die casting are best for your projects:

  • Design Complexity: It’s important to know about the part’s design complexity. Sunrise Metal focuses on part geometry and design details because it plays a crucial part in choosing the most appropriate process. Sunrise Metal offers excellent design flexibility, and we manufacture too complex designs with utmost precision.

We can achieve results with maximum dimensional precision, complex geometries, and thin-walled through low volume die casting. Low volume die casting services offers good dimensional results.

  • Material Selection: A wide range of alloys can be used in low volume die casting. However, aluminum alloys are most preferred for fast production and cost-effective solution.
  • Annual Usage: One of the most significant disadvantages of every other process instead of die casting is that they only make sense for large volume production. You can use these processes, but the final decision usually makes by focusing on minimum tooling costs. You can achieve the best quality parts rapidly and cost-effectively through die casting.
  • Part Size: There can be some part size limitations during low volume die casting, but the limits always apply after observing the required part completely. Every casting technique comes with its size limitations. However, die casting is the most less restrictive of them all. The thing that requires the focus is that the larger the part, the larger the tool, the larger the tooling cost.

How to reduce Die Casting costs with better designs?

Die-casting has become essential to manufacturing across various industries. Therefore, minimizing the overall costs of this widely used proves is critical to improving profitability. It is proven a simple process with low incremental and tooling costs. Many factors contribute to the complexity and cost of the die casting process.

The following are the most important nine ways of designing your parts in-order-to reduce die-casting costs:

  • Minimize the number of undercuts: The definition of an undercut is that it’s a part of the design that barricades its withdrawal from die casting mold. These are classified as internal and external undercuts based on their location within the part geometry. There can be exterior or inside undercuts. Most importantly, molding undercuts require side activities that can add 20-25% to the overall cost. Side actions are required due to an increase in machining complexity. The overall process increases the cycle times by 15-20%. That’s the reason why we prefer fewer undercuts in your part design so that overall die casting cost can reduce.
  • Minimize the wall thickness: To minimum acceptable level required for the application, there comes the need to keep the wall thickness of parts as close as possible. Doing so will reduce the cycle time. Reduction in injection time and cooling time automatically affect the overall production time and volume of material consumed. Decreasing the volume of the part required has a direct correlation to the production cost. Shorter cycle times and less material waste will automatically reduce a significant portion of the overall cost. That’s why thin walls are the preferred choice for low volume die casting.
  • Keep wall thickness uniform: Designing parts with various wall thickness can result in uneven cooling, causing deformation. It will increase the chances of bubbles formation, hot tears, ejector marks, and dimensional inaccuracies. A high quantity of manufactured parts with defects ending up in the rejection area increases production costs due to an increase in defect rate. Not only do they cost resources and time spent on lousy design parts go to waste. But also, more inefficient cycles are required to meet the customers’ requirements.
  • Use fillets and radii in the mold cast: Part’s Sharpe angled edges in the design cause stress concentration and increase the fracture rate. Which also becomes the reason behind the extreme cost. We can avoid this by including fillets and radii. Fillets are the inner corners of the part, and radii are the outer ones, which provide rounded edges in your part design. Remember, increasing the radius of the edges too much can cause shrinkage porosity. Thus, your die casting part design needs to use optimum dimensions.
  • Minimize the number of sliders: In low volume die casting, we can decrease the number of side actions by performing unique methods. Like, instead of just two mold halves coming together to shape the part, another piece is required that moves in from the side. This extra mold piece also helps to form the part surfaces in a way that helps the part to quickly release from the die casting molds. However, each additional direction increases the overall part costs by 15-20%. Even if the required parts need side-action, try to align all the parts to one side to reduce low volume die-casting costs.
  • Include appropriate draft angles: Holes and widows of the parts require more drafts than inside and outside wall features.

Using incorrect drafts or excluding it can result in fractured and damaged parts and extended production times.

  • Include ribs (and webs): To increase stiffness and add strength to the part, including ribs. This will result in a lighter part that’s sturdier than its standard version. A thin wall with ribs is sturdier, and the resulting part can be extremely lightweight and durable.
  • Design sturdy bosses: The bosses are singular features added to a die casting. A boss refers to a mounting feature that can receive a screw or thread-forming screw. We suggest using ample fillets and ribs in your die casting part design to ensure that molten Aluminum can easily flow into the boss area. Designing the bosses poorly can result in waste, so it’s essential to pay extra attention to the details.
  • Decide on hot vs. cold chamber die casting: Your low volume die casting requirements can be fulfilled precisely by selecting the most appropriate die casting methods.

  • To ensure our customer’s low-volume die-casting parts with high-quality and stability, Sunrise Metal has established an impressive set of management and quality-control processes from the feed to the process.

How our Low Volume Die Casting Services save you cost?

The majority of our new customers think that low volume die-casting costs per part go down as the volume goes up. If you want to make cheap parts, you should produce them in high volume. But, it’s not necessary because if you’re going to high volume die-casting production, then you must make a more considerable investment in more expensive tools. Furthermore, it needs to be hardened and heat-treated more carefully to withstand high temperatures and complex environments.

With this in mind, low volume die-casting is an excellent way to avoid large investments while still producing high-quality and completely functional parts.

The typical scenario we discussed before doesn’t apply here. In case the tool doesn’t require to be durable, it can be more economical for you to purchase and faster to heat treat.

  • DFM: Design for Manufacturing helps our clients to optimize the parts and mold design to save cost.
  • Rapid Tooling: Our rapid tooling service reduces the mold cost and makes a noticeable difference.
  • One-Stop Solution: Sunrise Metal is a one-stop die casting services provider and on-time delivery.

By comparison, high volume production requires massive investment and inventory of alloys and equipment.

To cover these expenses, you place a large minimum order quantity. An experienced engineer in low-volume production knows that the same amount of parts can be processed faster and cost-effectively without demanding any significant minimum order quantity.

How to choose the best solution for different volumes?

If you wonder that what solution should you choose to match the quantity and quality you required, Sunrise Metal got you covered! Our engineers will analyze your design and test it. After performing some tests, we discuss the core problems and defects your part can face. For low volume production, rapid prototypes and rapid tooling are the best solutions for customers worldwide. For medium and large volumes, die casting with production tooling is better. In these cases, tooling works alongside production to optimize the output of highly finishing die-cast parts.

After a complete professional evaluation, we state the best and most productive method suitable for your quantity at hand. Also, we make sure that our customers are informed about how the quality may differ in each type of process involved in the low volume production.

Welcome to contact Sunrise Metal if you have any requests about choosing a solution for different volumes.

How does the complex geometry of parts affect the Die Casting?

The complexity of part is always an essential factor to consider in low volume die casting. A complex part may have a different tool life compared to a part with simpler geometry. In low volume die casting, thanks to the superior part design freedom, the production is flexibly guided by design. By integration functionality into the die casting part during low-volume production, Sunrise Metal succeeded in significantly decreasing the number of individual parts and the assembly cost. As a result, the output parts are lightweight, durable, and cost-effective. We save time and money with minimum cost.

Different part geometry also affects the overall production cost along with production speed.  That’s why it’s essential to pay attention to the part’s design along with material and surface finish.

Complex Geometry of Low Volume Die Casting Parts

Does Low Volume Die Casting have certain limitations?

  • When working on low volume die casting projects, the complex parts can be handled easily but with not a maximum level of dimensional accuracy. However, the parts are fully functional but not as stable as final production. That’s the reason why further processing of die casting is required before final use to achieve maximum dimensional accuracy.
  • Limitations on mechanical strength properties and porosity
  • Safety hazards due to the handling of hot metals. However, at Sunrise Metal, our safety and environmental protocols are strict, and we don’t make mistakes.
  • It’s also important to keep track of temperatures. The term superhot is the temperature difference above the melting point of the alloy at which it’s poured. The term also refers to the amount of heat needed to be removed from the molten metal between pouring and solidification.

What is the purpose of Low Volume Die Casting?

At Sunrise Metal – China, our low volume die casting services serves the clients the following purposes:

  • “Replacement” die-casted parts that are no more in production or are otherwise unavailable for some other reason. These’re often parts for repair.
  • Our low volume die-casting services provide a bridge between initial prototyping and final high-volume die-casting production. This is the point where the parts will be manufactured using production (hard) tooling. Some people call it “pre-production parts.”
  • Low volume die casting parts are the parts made after the initial prototyping phase. These are the production parts but only for having the exact idea about how the part operates and what it faces in specific environments. Lowering our customer’s tooling costs, improving cash flow, are reducing the production time are some secondary purposes we provide our customers at Sunrise Metal.

High Precision Low Volume Die Casting

Are the Complex Low Volume Die Castings prone to porosity?

We believe that porosity is a commonly misused term and understood concept. There can be multiple potential sources of porosity in low volume die casting. Furthermore, there’re also many reasons for porosity.

Environmental gasses mostly cause porosity. This can be controlled with metal quality, vacuum melting, and proper de-gassing procedures at the melt deck.

Another primary source of porosity is that it occurs due to turbulence and splashing when the die casting metal is poured. It causing the environmental air in the mold to become entrapped. A proper gate, runner, and design, useful pouring techniques, and filtering can be used to minimize the overall turbulence. And it’s used to reduce the entrapment of environmental air.

In the end, what some refer to as porosity is shrunk inside the die-casting due to the volumetric change that occurs in the alloy as it changes from liquid to solid. The shrink can be eliminated or reduced by choosing a good die casting design. The selection of critical gate sizes and locations can eliminate the shrinkage.

Good alloy selection, proper poring temperature control, and finalized part cooling is fundamental to decrease and eliminate shrink during the low volume die casting. If the parts are precisely and adequately designed, and the die casting processes are controlled accurately, porosity can be minimized.

What is the MOQ of Sunrise Metal for Low Volume Die Casting production?

Low volume die-casting aluminum alloys are lightweight while processing high dimensional stability for complex design parts and thin walls. Due to our specialty in low volume die casting, we are very flexible in order quantities.

Sunrise Metal’s quotes always break down the overall cost by MOQ’s; there can be a price premium if the order is below 3.000 pcs. Or there can be an alternative, cost-effective solution to our customer’s project if the order is below 1,500 pcs. (Remember! These numbers are just, for example).

How does Sunrise Metal ensure the on-time delivery of Low Volume Die Casting products?

Sunrise Metal measure the OTD (On-Time Delivery) through the following and keep track of the overall progress:

  • Calendar Days vs. Working Days: It’s the most common misunderstood term between customers. Do the five days include weekends? It’s acceptable either way, but customers must clear the complete detailed routine.
  • Promise Date vs. Required Date: Required Date vs. Promised Date: Require date describes the deadline by the customers, and the promise date describes the date committed to meet by low volume die casting services provider. Near Sunrise Metal, the promise date is the best practice.
  • Percent of line item vs. percent of the quantity ordered: A line item is a single part, and we calculate the overall parts per day we need to die-cast to meet the promised date.

Below are the ways through which we improve OTD:

  • By ensuring and maintaining the accurate inventory records
  • We create realistic production schedules and maintain them at any cost
  • We monitor efficiency on every step and maintain it
  • Build a strong relationship with our customers

  • DFM (Design for Manufacturing)

Using low volume die casting services, creating a fully optimized part design before tooling is important. Because it can make the entire process more efficient and result in more quality at a lower cost. Utilizing DFM for optimization purposes is good practice.

This is an excellent service and cost-effective way to produce parts without using any additive processes. Rapid prototyping is ideal for Aluminum. Rapid prototyping is mostly utilized for low volume production.

  • Rapid Tooling

Rapid tooling does not require time-consuming and costly pattern making. Rapid tooling is, therefore, widely employed in many industries to produce low volume parts and prototypes. It helps reducing lead casting design time and accurate the introduction of new components.

Die casting is considered as the most rapid and economical part production technique. All parts produced using die casting have uniform quality and involve relatively low unit costs.

  • CNC Machining:

CNC machining has shorter lead times and offers higher precision and repeatability. It requires a detailed manufacturing plan and unique for low volume production. However, the basic principles of CNC machining are similar to traditional manufacturing methods.

The surface treatment service includes anodizing, printing, painting, and coating. Furthermore, it’s just not limited to these four treatments. It’s a possible way to obtain sufficient resistance against environmental hazards, including high-temperature oxidation.
