Investment lost wax casting


Investment casting (also known as lost wax investment casting) produces parts with fine detail and excellent casting surface finish. Investment casting is molded into internal or external features, thin walls and internal channels to achieve near-net shapes.

Materials are used in investment casting


Stainless Steel

Stainless steel has excellent durability, and the material’s potential has led to an increase in use by designers and engineers in investment casting. Applications for stainless steel include transmission components in automotive applications, various gears, camp components and golf club heads.

Low-Alloy Steels

Low alloy steel is one of the most frequently used steels in the mechanical world because of its low price and beneficial mechanical properties. Specialized heat treatment processes make it possible to design parts with different properties in different areas of the same workpiece. For example, different heat treatments can be used to make one surface tough and impact resistant, while another becomes wear resistant.

Aluminum alloys

Aluminum is the most used material in investment casting. Industries that use it most often include aerospace, avionics, electronics, and military.

Due to the increased strength of the material and the availability of quality castings made from aluminum-silicon-magnesium alloys, it is now possible to provide castings for demanding applications like airframe components.

Carbon Steel

Carbon steel is a common, low-cost material that comes in a variety of grades, and its classification varies according to the amount of carbon content. In industrial applications, the strength, ductility, and properties of carbon steel can be improved by heat treatment. Its ferromagnetic properties make carbon steel useful in electric motors and appliances. It is safe, durable and has a high level of structural integrity, making it one of the most frequently used alloys in the world.

Super Alloys

Nickel and cobalt-based superalloys have universal use in the aerospace, energy, medical, chemical, and marine industries. Nickel-based alloys are stronger at high temperatures, and cobalt-based alloys offer greater resistance to corrosion, oxidation and wear than nickel-based alloys. Super alloys are increasingly replacing sheet metal because they offer high rigidity and excellent service characteristics while still being a cost-effective option.

Copper Alloys

Copper-based alloys offer corrosion resistance and low wear rates. They are often used in applications such as a ship or pump propellers, electrical components, and piping elements. As a versatile material, there are more than 400 different alloys with a wide range of properties.

Many part types can be investment cast in copper-based alloys. Some of the more common types of copper-based alloys include bronze and brass. The strongest copper alloy is beryllium copper, which has similar properties to high-strength alloy steels but has higher corrosion resistance over a longer period of time.

Cast Iron

Iron castings, which typically include gray iron and ductile iron, are known for their high precision and affordable price. Ductile iron has higher strength, heat resistance and toughness, but it is more complex to produce than other steels. This results in higher production costs than cast steel.

Advantages of Investment Casting 2023


Excellent surface finish

The investment casting process provides a superior surface finish compared to forgings and sand castings. This is sometimes important to avoid machining or other finishing operations.

Wide variety of materials

Investment cast parts can be cast in a range of alloys, including stainless steel, brass, bronze, cobalt, nickel, and custom alloys. Alloys cast by Easiahome are used in a wide variety of industries.

Closer to the design of the finished part

Investment casting provides a near-net shape for manufactured parts, thereby eliminating or reducing machining costs. Another benefit of near-net shape is the material savings, especially in more expensive alloys like nickel and cobalt alloys.

Complex designs

Holes undercuts, slots, and other difficult details that cannot be provided by other processes can often be provided by investment casting – thereby reducing the amount of machining. Logos, numbers, or names can be added to the part as markings.

Difficult thin-walled castings

The investment casting process is capable of producing reliable castings with thinner wall thicknesses than sand castings. The advantages include a much lower scrap rate and a lighter-weight casting due to the thinner walls.

Tight tolerances

Due to the nature of the process, the tolerances for investment casting are much tighter than for sand casting or forging. Tolerances can be as tight as + – 0.1 mm – resulting in a highly accurate cast part.

Competitive mold costs

With Easiahome’s own in-house tooling manufacturing, the initial cost of investing in casting tooling is typically lower than that of die casting and forgings.

Minimized casting defects

As a cleaner process than sand casting, investment casting generally provides a higher percentage of defect-free castings.

Rapid Prototyping for New Product Development

Rapid prototyping can get products to market faster. Easiahome Company uses 3-D wax modeling to improve the efficiency and speed of design and production. Using 3-D modeling, FBPC can move from the development phase to production much faster. 3-D modeling is particularly beneficial for companies that require rapid, small-order prototyping because wax molds are not required. This speed to market helps customers compete in the marketplace.

And …… They look better!

Investment casting has a high-quality appearance, whether appearance is important or not. Minimal or no recognizable demarcation lines are normal. In addition, most exterior surfaces do not require a draft.
