Comparing Investment Casting Companies

When comparing investment casting companies for your next manufacturing project, it’s important to know about all of the material options, tolerances, and in-house machining options.

Although investment casting is one of the oldest and most trusted manufacturing techniques used for metal parts and components, casting services, processes, and quality standards vary between foundries.

Investment Casting Options?

Investment casting options use a variety of specialized processes for casting metals into precise, accurate shapes and units from a mold. The metal part is produced to deliver tight tolerances and a smooth surface finish.

The most common metals used for investment casting are:

  • Alloy Steel
  • Aluminum
  • Carbon steel
  • Copper
  • Stainless Steel

Investment Casting Comparison Checklist

Investment casting is popular among project managers and leads because it offers many advantages over other methods of casting for complex designs, a wide range of alloys, minimal tooling costs, and minimal size restrictions. The investment casting process is common for making parts for large-scale industrial projects in the aerospace, automotive, firearms, and railway industries.

What do project managers look for when comparing investment casting companies?

  • Projects delivered with accuracy and integrity
  • Delivery on tight tolerances and smooth surface finishes
  • Industry-specific expertise
  • Customer support and consultations
  • One-stop casting services – no outsourcing
  • Competitive investment casting costs without sacrificing quality

If you’re unsure whether investment casting is the right process for your project, an experienced support team will help you decide. Make sure the following topics are covered in your initial consultation:


Discuss the complexity of the part, product iterations, budget, and material preferences. Next, learn about the prototyping process. If an investment casting company has experience in delivering superior results, you’ll learn about their state-of-the-art equipment, and machining and testing processes.

Part Size & Requirements

Part size and requirements are another consideration. While parts up to 2,000 lbs have been cast successfully, it’s not always recommended for parts weighing more than 100 – 200 lbs. Parts that require cores are not recommended for investment casting.


The size of your order will play a role in the cost of investment casting. Many investment casting companies offer lower per-unit costs for large-volume / large production orders.

Nothing is more important in choosing the right casting company and finding one that encourages early supplier involvement. An experienced casting company with a reputation for success knows how to guide you in the right direction and choose the right material for your project and budget. They’ll be able to give you an accurate investment casting cost estimate quickly and easily.
