How to Choose the Best Aluminum Foundry for Your Manufacturing Needs

As a manufacturer, you know that finding reliable aluminum casting foundry services can be a difficult task. With so many options available, it’s hard to know who is right for your specific requirements. When choosing the best aluminum foundry for your manufacturing needs, several important factors must be considered.

Asking the foundry questions, considering their quality, and researching their qualifications will help ensure that you select an aluminum casting provider who can deliver both quality results and exceptional customer service. In this blog post, we’ll cover some key points to consider when selecting the best aluminum foundry for your manufacturing needs and other important tips.

1. Your Potential Aluminum Foundry Should Have Experience & Expertise

When selecting an aluminum foundry for your manufacturing requirements, it’s crucial to study several factors. One of the most critical aspects to consider is the experience and competence of the foundry. Choosing a foundry who has the right knowledge of the aluminum casting process, and the portfolio to show for it, helps to have a successful outcome for your project.

The foundry should be able to provide you a list of past projects or customer references that showcase their skill and attention to detail. These references help to confirm that the foundry has the necessary equipment and processes to produce your products efficiently and cost-effectively. 

In addition, a good aluminum foundry should have a dedicated team of engineers who can provide you with guidance and advice on product development to start your project off in the right direction.  Preparation and planning are key to a successful project. Having the experience and industry knowledge to engineer your castings for optimal production and quality outcomes will streamline the project. 

Producing aluminum castings requires a complex set of processes to achieve the right results. When deciding on a new aluminum foundry to partner with, ensure they have extensive industry experience and are knowledgeable about all aspects of the aluminum casting process:  design, production, material analysis, and product testing. These expertise will allow them to give you valuable advice on which casting processes, alloys, and techniques should be used for your project to produce the best final product. The foundry should also have a proven track record of delivering exceptional products that meet or exceed customer expectations.

2. The Quality Control of the Aluminum Casting Process

Quality control should also be at the top of your list when choosing an aluminum foundry. By working with a qualified foundry who follows the standards for quality control, you can protect the integrity of your product and ensure it meets your specifications.

Quality Measures For Aluminum Part Production

Using aluminum castings  as a component in your product offers many benefits, but none without proper attention to quality control.  Aluminum cast parts made by an experienced foundry should be subject to rigorous quality control measures. Check that the foundry has a quality assurance policy that includes regular inspections and testing of cast aluminum products as well as quality control over manufacturing processes and materials. Ideally, the foundry that you choose has NDT (Non-Destructive Testing) capabilities in-house, but if not, ensure that the foundry has access to accredited quality labs. That is why using a reliable foundry who understands the importance of quality control measures like BAF, helps ensure that your end product checks all the right boxes.


Verifying the aluminum foundry you partner with is familiar with, and capable of meeting industry-based specifications is another critical step.  Several specifications have been published by accredited associations to set standards for aluminum castings used in both commercial and defense applications, including the ASTM, the American Aluminum Association, and the military sector.  Boose sets their production parameters to meet the following specifications:

  • Aluminum Association Commercial Castings
  • ASTM B26/B26M – Standard Specification for Aluminum-Alloy Sand Castings
  • MIL-A-21180D Class D or C – High-strength aluminum alloy castings
  • Tolerances: per Aluminum Association Standards

Certifications & Accreditations For Aluminum Part Manufacturing Processes

Additionally, inquire about any certifications or third-party accreditations that the foundry holds. These accolades demonstrate their commitment to producing high-quality parts and can indicate their reliability and attention to detail. Checking for these certifications should be on your checklist if your aluminum castings are destined for use in specific operations since certain industries require additional certifications.

Aerospace & Medical Industry Certification Standards

Aluminum foundry-held certifications are required to make parts for the aerospace and medical industry such as ISO 9001 certifications. These certifications help ensure the aluminum castings are produced safely and adhere to quality standards.

3. The Range Of Services The Foundry Offers

When looking for an aluminum foundry, it is important to consider its range of services. These services can include things like:

  • Casting design and product development
  • Solidification Modeling
  • Pattern making
  • Prototyping
  • Core making processes: shell, cold box, no-bake, 3D sand printing
  • Molding processes: sand casting in no-bake or green sand, permanent mold, die casting, etc.
  • Surface finishing: grinding, abrasive blast
  • Heat treatment
  • Non-destructive testing: radiography, liquid penetrant inspection, Brinell, tensile strength, gauging
  • Metallurgical analysis
  • 3D printing
  • First Article Inspection/PPAP: 3D Scanned or Traditional Layout
  • Machining capabilities or guidance towards reliable machine shops familiar with castings.

By selecting a company who offers services that meet or exceed your product requirements, you can be sure that your project will be completed with the utmost precision and efficiency.

Aluminum Foundry Specialization

Certain aluminum foundries specialize in specific types of manufacturing processes or casting methods. Different parts require different production techniques to cast aluminum, such as sand casting or die casting . It is important to select a foundry that can accommodate your specific needs and provide the focus in the area you require.  At Boose Aluminum, we specialize in quality sand casting including both greensand and chemically bonded no-bake sand molding techniques. 

From the composition of aluminum alloys to the control of molten aluminum temperature, and from the characteristics of the molding sand to the properties of a heat-treated casting, each step in the casting process is critical for achieving the desired result. Each foundry has their own experiences, specialties, and molding techniques.  Taking the time to find a reputable aluminum foundry that specializes in the casting method and alloy that will best provide you with your desired product is a critical first step in the process.
