RLM Industries – Premier Investment Casting

What do spaceships, surgical tools, and heavy-duty farming equipment all have in common? They all depend on the precise and detailed manufacturing process known as investment casting.

Welcome to RLM Industries, where precision meets tradition in the art of investment casting. With over four decades of expertise, RLM Industries has set a standard for quality and innovation in the metal casting industry. Our services range from advanced prototyping to custom metal casting, all underpinned by rigorous engineering practices.

Here, we explore the nuances of our services and what makes us the premier choice for your casting needs.

What is Investment Casting?

Investment casting, also known as precision casting, is a method of producing metal parts with intricate detail and excellent surface quality. At RLM Industries, this process involves creating a wax model of the desired part and then coating it with a ceramic material that hardens into a shell.

The wax is melted away, leaving a mold into which molten metal is poured. Once solidified, the ceramic shell is broken off, revealing a high-fidelity metal part. This method is ideal for creating components that are complex in shape, with dimensional accuracy and integrity that other casting methods can’t match.

Investment casting is celebrated for its versatility in working with a wide array of metals and alloys, allowing for a broad spectrum of mechanical properties and applications. From aerospace to the medical fields, our casting services provide critical components that meet rigorous standards, including DFAR and ITAR compliance for defense-related applications.

Industry-Specific Applications of Investment Casting

Investment casting is a foundational technique in manufacturing intricate parts across a multitude of sectors. This process not only meets diverse industrial needs but also adapts to the rigorous standards of various fields. Here’s how different industries use investment casting to create parts that are as robust as they are intricate:

  • Aerospace: This method crafts crucial parts such as turbine blades, structural components for jet engines, and cockpit instrumentation for both commercial and military aircraft. These components require exact specifications for optimal aerodynamics and safety.
  • Automotive: Investment casting produces complex engine components, transmission parts, and structural elements that contribute to vehicle durability and performance. This includes casting for aluminum gearboxes and steel suspension arms.
  • Medical: In the medical field, investment casting is used for creating orthopedic implants like hip and knee replacements, as well as surgical tools and device components that require high precision and compatibility with human tissue.
  • Military: The defense industry relies on investment casting for manufacturing robust parts that can withstand extreme conditions, such as casings for missile and aerospace applications, components for firearms, and communication devices.
  • Manufacturing: Investment casting supports the production of machinery components used in industrial applications. These parts often need to withstand high temperatures and pressures, providing longevity and efficiency.
  • Agricultural: For the agricultural sector, investment casting produces durable parts for machinery such as tractors, combines, and irrigation systems. These components often require complex shapes that can endure the harsh conditions of farming environments.

By using investment casting, industries benefit from the ability to create durable, complex parts tailored to their specific needs, enhancing product performance and reliability.
