What Are Thin Wall Precision Castings?

Thin wall precision castings are specialized metal components characterized by their minimal wall thickness, typically much finer than those achievable by standard casting techniques. This advanced casting method produces parts with complex geometries and strict dimensions, which are essential in industries requiring high precision and lightweight components. 

Leveraging our extensive expertise, Bescast produces thin wall stainless steel castings and nickel-based castings to meet diverse industry needs, ensuring the final products exhibit superior performance and durability. 

Thin Wall Precision Metal Castings: Advantages and Features

Our thin wall precision metal casting expertise delivers a significant advantage for our customers. When you partner with Bescast, you get benefits like:

  • Precision and Complexity: Thin wall investment casting creates parts with intricate shapes and details that are not possible with other manufacturing processes. This precision means components fit perfectly in complex assemblies, reducing the need for post-processing.
  • Reduced Weight and Material Usage: By producing thinner walls, this casting process significantly lowers the weight of components, which is critical in industries like aerospace and automotive for fuel efficiency and overall performance.
  • Enhanced Mechanical Performance: The parts made through thin wall precision casting typically have better mechanical properties, such as strength and durability, due to the fine-grained microstructure achieved in the casting process.
  • Improved Surface Finish and Aesthetic Qualities: These castings have a smoother surface compared to those made with conventional methods, reducing the need for additional surface finishing and enhancing the aesthetic appeal of the final product.

Applications for Thin Wall Precision Castings

Thin wall precision castings are revolutionizing industries with their versatility and superior properties. From aerospace to medical fields, these castings are integral in applications where precision, strength and lightweight materials are crucial. Their adoption across various sectors highlights their importance in modern manufacturing and engineering. We put our thin wall expertise to use for numerous parts, including military and defense castings and petroleum industry castings. You can also find precision thin wall metal castings in applications like:

  • Aerospace and Aviation: Components like turbine blades and structural parts for aircraft and satellites, where strength and lightness are critical
  • Automotive Components: Precision parts such as gearbox cases and engine components that require durability and reduced weight
  • Medical Equipment: Surgical tools and implantable devices that demand high precision and biocompatibility
  • Industrial Machinery: Gears, valves and fittings that need high strength and wear resistance

The Process Behind Thin Wall Precision Castings

The investment casting process involves a meticulous step-by-step procedure to produce thin wall precision castings. Before taking the first step, we use ProCAST software and our extensive engineering expertise to make sure the part will meet customer expectations.

Precision Metal Casting

Investment casting begins with developing a detailed wax model, which is then encased in a ceramic shell, capturing every intricate detail. The wax is melted away, creating a hollow mold into which molten metal is poured. Once the metal cools, we remove the ceramic shell to reveal the final part, which usually requires few, if any secondary, procedures.


Each stage of investment casting, from the wax model creation to the final metal casting, is critical for achieving the thin walls characteristic of these components.

The Role of Standards in Thin Wall Precision Metal Casting

Adherence to quality certifications and standards, such as ISO 9001, is crucial in thin wall precision metal casting. These certifications ensure that manufacturers like Bescast meet global standards for quality management and product consistency. 


Quality control measures, including dimensional inspections, material testing and structural analysis, are rigorously applied throughout the production process to ensure the castings meet the highest performance and safety criteria. This commitment to compliance and quality is essential for customer trust and product reliability. Our certifications include:

  • ISO 9001:2015
  • AS9100 Rev D
  • Nadcap

  • Heat Treat

  • NDT (Non-Destructive Testing) (Radiography & Penetrant)

  • Welding

The Benefits of Thin Wall Precision Castings

Choosing thin wall precision castings offers essential benefits for applications across numerous industries. Cost savings are a significant benefit, not just in the direct reduction of materials used but also through the minimization of machining and finishing requirements due to the precision of the casting process. This efficiency reduces labor and production time, contributing to overall savings.


Environmentally, thin wall castings are a more sustainable option. Reducing material waste aligns with eco-friendly practices and helps companies meet environmental regulations.


Enhanced performance and longevity stem from the superior strength-to-weight ratio of thin-walled components, which leads to higher efficiency and durability in operational environments. This improvement in part lifespan reduces the need for frequent replacements, offering long-term savings and performance benefits.
