Which Process Fits Your Project?

Die Casting vs. Investment Casting

Die casting and investment casting are two proven casting methods for manufacturing complex metal components. Each offers specific benefits – depending on the application, material requirements, quantity, and tolerance demands.

In this comparison, we outline the differences between die casting and investment casting and help you choose the right process.

What is Die Casting?

In the die casting process, molten metal is injected into a metallic permanent mold under high pressure. It is particularly suitable for fast serial production of precise parts made of light metals like aluminum, zinc, or magnesium.

Typical applications: Automotive industry, consumer goods, electronics, mechanical engineering.

What is Investment Casting?

Investment casting, also known as precision casting, is based on the lost-wax process. A disposable mold is created anew each time. This method enables highly precise production of complex geometries – even in very small quantities.

Typical applications: Aerospace, medical technology, mechanical engineering, toolmaking, automotive industry, defense.

Comparison: Die Casting vs. Investment Casting

Criterion Die Casting Investment Casting
Mold Type Permanent mold (metal) Disposable mold (ceramic)
Pressure High pressure (up to 1200 bar) Gravity casting
Dimensional Accuracy High, limited by tool wear Very high, even for complex geometries
Surface Quality Smooth, suitable for post-processing Very fine, often no post-processing needed
Material Range Only low-melting metals (Al, Zn, Mg) Almost all metals incl. steel, titanium, nickel
Economics Best for large series Ideal for prototypes, small and large series
Tooling Costs High, but durable Low, due to disposable mold
Tolerances Good, but limited (DIN EN ISO 8062-3) Very precise, tight tolerances possible

When to Use Which Process?

Die casting is your choice for large series where fast, automated, and cost-efficient production is required.

Investment casting is ideal for complex geometries, small to large quantities, and when the highest precision and material variety are needed.
