Why Use Our Metal Price Calculator?

  • Precision quoting based on your part’s exact volume
  • Fast quotes for both prototype and production needs
  • Real-world pricing using Kormax’s actual materials and casting methods
  • Ideal for design engineers, purchasing departments and manufacturers needing quick, accurate cost information

What Affects Casting Cost?

Your instant estimate is based on several key factors:

Part Volume

Automatically calculated from your 3D CAD file to determine material requirements.

Material Type

Choose from engineering metals like stainless steel, chromium alloys and more. Discover more about the metals we offer for casting on our Metals Overview page.

Casting Method

  1. Investment Casting is best for high-detail, complex parts
  2. Sand Casting is more cost-effective for larger volumes or simpler shapes.

Quantity / Scale of Production

Unit costs vary based on batch size. Larger runs often reduce per-part pricing.

For a full breakdown of what impacts casting costs, read our detailed cost guide.

Frequently Asked Questions

How is casting weight calculated?

Casting weight is typically calculated in the metal casting weight calculator using the following formula:

Casting Weight = Volume of the Part × Density of the Material

Note: The estimate may also account for additional material allowances such as runners, risers and machining stock, depending on the casting method and part complexity.

What’s the difference between sand and investment casting?

Both sand casting and investment casting are popular methods for producing metal parts, but they’re suited to different applications:

  • Sand Casting Cost Calculator
    Ideal for larger, less complex components, sand casting uses a sand-based mould and is generally more cost-effective for high-volume or heavy-duty parts. It’s commonly used in industrial and structural applications.
    → Learn more about sand casting.
  • Investment Casting Cost Calculator
    Best for smaller, highly detailed parts, investment casting uses a wax pattern and ceramic mould to deliver smooth finishes and precise tolerances. It’s perfect for intricate components where accuracy and surface quality matter.

Choosing the right casting method depends on your part’s geometry, desired finish, material and production volume.

What materials are supported?

The calculator supports a wide range of engineering metals suitable for both sand and investment casting, including:

For more details, explore our supported casting metals.

What file types does the calculator support?

You can upload files in the following formats:

  • STEP
  • IGES
  • STL
  • DWG
  • DXF

These formats allow us to accurately extract volume data from your design.

Can I get a quote without uploading a file?

This tool requires a file to provide accurate volume and cost estimates. If you don’t have a file yet or your design is still in progress, contact our team for a manual quote based on your specifications.

Is the metal cost calculator accurate for small production runs or prototypes?

The metal price calculator provides useful estimates for both small and large runs. However, for one-off prototypes or very low volumes, pricing may vary depending on setup and tooling costs. Contact us for tailored advice.

Are there any other costs not reflected in the pricing calculators?

The calculator provides an instant estimate based on your part’s volume, selected material and casting method. However, final quotes may include additional costs such as:

  • Tooling or mould setup (especially for new or complex designs)
    Finishing services like machining, coating or heat treatment
  • Shipping and logistics, depending on destination and weight
  • Special quality control or testing requirements

These factors are assessed during manual review to ensure your final quote reflects the full scope of your project. For a detailed breakdown, read our casting cost guide.
