Forging Precision and Strength: Discover the Power of Closed Die Forgings
Closed Die Forgings are revolutionizing the manufacturing world by providing high-strength, high-precision components across various industries. At Laube, we’ve been delivering top-tier Closed Die Forgings for over 75 years, earning a reputation for quality, reliability, and partnership. Whether you need custom parts or mass production, our team brings decades of expertise to every stage of your project—from ideation to final delivery.
What Are Closed Die Forgings?
Closed Die Forgings, also known as impression die forgings, are a metal forming process where metal is shaped by pressing it within the contours of a specially designed die. The force and confinement of the die allow for accurate and repeatable shaping of components, resulting in exceptional mechanical properties and minimal material waste.

Why Choose Closed Die Forgings?
Precision and Consistency
Each forging is formed within a dedicated die set, ensuring accurate and uniform results—ideal for industries that require strict tolerances.
Strength and Durability
Closed Die Forgings are known for their superior grain structure and mechanical properties, often outperforming cast or machined components.
Cost-Effective at Scale
Although die creation is an initial investment, once in production, the unit cost drops significantly, making it ideal for medium to high-volume runs.

Types of Closed Die Forgings Applications (Trending in 2025)
Precision Aerospace Fittings – Ultra-strong and lightweight titanium or aluminum parts.
EV Powertrain Components – Demand for closed die aluminum forgings is surging.
Hydraulic Couplings – Steel-based forgings for high-pressure use.
Heavy Construction Tools – Forgings designed to endure high-impact use.
How Closed Die Forgings Are Made
Design Phase – CAD models and simulations are created to ensure optimal die geometry.
Die Fabrication – Tool steel is machined and heat-treated to form the dies.
Heating the Material – Billets are heated to forging temperature (typically 1800°F for steel).
Forging – The billet is placed in the die and compressed under immense force.
Trimming – Excess material is removed.
Heat Treatment – Final hardening and stress relieving.
Machining (if required) – Secondary finishing processes.

Frequently Asked Questions About Closed Die Forgings
1. What’s the difference between closed die and open die forgings?
Closed die forgings use molds to shape the metal precisely, while open die uses flat dies and is better for large, simple parts.
2. What are the advantages of closed die forgings?
Greater dimensional accuracy, better surface finish, and improved material strength.
3. Are closed die forgings cost-effective?
Yes, especially for medium to high-volume production.
4. Can Laube create prototypes?
Yes, we help clients from ideation through to final production.
5. Do you offer heat treatment services?
