Choosing the right metal casting supplier isn’t just a procurement decision — it’s a strategic move that can directly impact your product quality, production timelines, and long-term profitability. Whether you’re sourcing components for the automotive, aerospace, agricultural, or industrial machinery sector, the right foundry partner ensures performance, precision, and consistency.

Here are 10 essential questions to ask before partnering with any metal casting manufacturing company.
From sand casting to die casting and investment casting, each process has unique advantages. Ensure the supplier has proven experience in your required process and can demonstrate results from similar industries or components.
A qualified foundry supplier should be ISO certified at minimum. Depending on your industry, look for IATF (automotive), AS (aerospace), or other relevant quality management certifications.
Suppliers with experience in your sector are more likely to meet quality, regulatory, and functional expectations. Ask for references or case studies in industries like automotive casting, heavy equipment, or energy components.
Can the supplier handle volume changes or tight deadlines? Ask for average lead times, batch sizes, and how they manage production during demand surges.
A metal casting partner with internal tooling, mold making, and prototyping capabilities can help reduce lead time, cost, and communication gaps during development.
Non-destructive testing (NDT), 3D scanning, X-ray inspection, and chemical composition analysis are important for consistent, high-quality castings. Ask for their quality control workflow.
Material sourcing transparency is vital in many industries. The supplier should provide full traceability from raw material procurement to final casting.
Request a detailed breakdown covering tooling, per-part pricing, setup costs, and shipping. Also inquire about volume-based pricing and long-term cost optimization.
Strong suppliers contribute more than castings. They help optimize your designs for better mold flow, weight reduction, and manufacturability — saving you time and cost.
Your metal casting supplier should be responsive, structured, and proactive. Ask about communication channels, reporting frequency, and escalation processes for issues.

The right metal casting manufacturing partner offers more than just foundry services. They collaborate, improve product outcomes, and align with your long-term goals. By asking the right questions up front, you reduce risk and build a foundation for reliable supply and quality.
The die casting process can have significant advantages over other manufacturing processes—like machining and stamping—leading to major cost savings in piece price and overall cost of production. With die casting, you can create complex net-shapes, including complex internal and external features with minimal draft angles—minimizing secondary operations. But as with any production process, there is a lot to learn before making a decision on which process would be best for you component.
With competitive price and timely delivery, Yuhui sincerely hope to be your supplier and partner.
In January of , Form Technologies hosted the first installment of Metal Solutions Webinar Series – EU. This webinar, An Introduction to Precision Die Casting, presented by the European Dynacast team, aims to guide our customers on how to take advantage of the benefits of die casting. Our webinars present attendees with the opportunity to ask our experts real questions about the die casting process during our live question and answer section. Take a look at some of the most frequently asked questions below.
The minimum wall thickness that we can achieve is dependent on the part geometry and part design, but in an ideal scenario, Dynacast can cast aluminum walls as thin as 0.3mm. Generally, a minimum wall thickness of 0.5mm – 1.0mm is advisable to maintain high strength.
There is no one ideal wall thickness for a die casting component. Rather, it is exceedingly important to maintain consistent wall thickness and reduce weight where possible for a strong, cost-effective component. The best way to achieve this is to design optimized gate and overflow locations into your part design to avoid unnecessary porosity and maintain strength.
Dynacast prides itself on maintaining the tightest tolerances in the industry, but similarly to wall thickness, the tolerance is largely dependent on part geometry. For the most exact tolerances, generally between ±0.001" and ±0.002" is possible for zinc, whereas aluminum can hold between ±0.002" and ±0.004".
However, even though a tolerance of ±0.001" is possible with Dynacast, manufacturers must be careful to avoid engineering unnecessary cost into the design. Too often, companies will request exacting tolerances and minimal draft angles when such features are not needed to maximize part performance. As a result, their castings fail.
Instead, take a more holistic approach to your design. With the help of our die casting engineers, determine the non-critical dimensions of your component to allow for more lenient tolerance zones. In addition to extending the life of your tool since there are fewer exact geometries that wear down, allowing for tolerance zones also makes it easier to plan the tolerance stack-up of your entire component. This will help you to avoid machining and secondary operations wherever possible, making your design work for you to get the most out of the die casting process.
All of the die cast materials that we use, aluminum, zinc, and magnesium are environmentally friendly because they are recycled. At Dynacast, our plants work in a closed loop cycle, utilizing advanced re-melting capabilities to re-use any excess metal retrieved from our runner systems in the dies. After reclaiming the excess metal, Dynacast verifies the chemical composition with spectrometers to ensure that they maintain the physical and mechanical properties of newly sourced metal.
In terms of production, aluminum is the most environmentally friendly of all the die casting metals. Aluminum is 100% recyclable, and 75% of all the aluminum ever produced is still in use today. Since aluminum can be recycled again and again with no deterioration in its mechanical or physical properties, it can serve the same applications with the same level of performance as primary aluminum extracted directly from bauxite ore—all while having a positive impact on the environment and your bottom line.
The physical and mechanical properties of aluminum make it the ideal choice for parts that can be used in almost any industry, including aerospace, defense, consumer electronics, healthcare, automotive, and more.
The benefits of die casting are largely associated with production speed and total piece price savings. Dynacast's multi-slide machines can be designed with multiple cavities and enable our engineers to cast extremely complex parts, quickly. Our multi-slide die casting machines cycle at speeds of up to 75 cycles per minute, delivering 4,500 shots per hour. In a two-cavity tool, this means 9,000 parts per hour.
A faster cycle time contributes to lowered overall cost per piece. Additionally, die cast tools ensure unmatched complexity of internal and external geometries, so there are fewer secondary operations associated with die casting. With multi-slide die casting, you can cast complex geometries that would otherwise need to be manufactured from two or more pieces and assembled using any other processes.
While screw machining offers a lower up-front tooling cost, die casting more than makes up for that in the overall peice price savings. On an ideal part (one that is small, high volume, and can be cast in zinc), the tool is paid back in full somewhere between 10-14 months of production. Every part made after that is an earning towards your bottom line.
The level of environmental resistance offered depends on the material and your project requirements. Zinc, for example, is relatively self-resistant in comparison to aluminum alloys, but you will get some zinc oxide, or white rust. However, if you need a high level of environmental resistance for your die cast component, we recommend utilizing one of our surface treatments—from treatments and coatings that offer corrosion resistance, high-gloss finishing, painting, and more.
The cost effectiveness of the die casting process needs to be evaluated on a case-by-case basis. There are many cases in which converting to die casting from screw machining, machining from solid, stamping, and welding results in better part performance and better cost at full-scale production. However, we invite you to contact an engineer to determine if converting to die casting is the best solution for you.
With over 80 years of experience, Dynacast consistently delivers value through engineering expertise, efficient operations, and Advanced Quality Planning systems.
