What is investment casting

Investment casting is a manufacturing process that uses wax to create a pattern, which is then used to make a part. It is commonly used to make small and intricate parts that would be too difficult and expensive to make using other methods. The process is often used to make parts for engines and other complex machinery. The engine in your car, for example, is almost certainly made using investment casting.

It is the process of making a mould, or negative shape, from which a final product is made. Casting can be used to make a wide variety of products, including machine parts, medical devices, and jewellery. Investment casting is a type of casting that uses a metal called investment to help create a mould. The first step in the process is to build a pattern, or model, of the final product using a material such as wax.

The history of investment casting goes back to the very beginning of the manufacturing process. The first object cast using this method was a cannon in 1733. The process was improved upon and was used to make small parts for firearms and machines. However, it was not until the 20th century that the process was used to make large, complex parts.

In the world of investment casting, history is made on a continuous basis thanks to the rapid prototyping processes used to create new parts for industrial machines and injection moulding machines. In the past, investors would build full-scale moulds from metal and then cast metal parts inside those moulds. Today, however, engineers use computer-aided manufacturing (CAM) and rapid prototyping processes to build digital 3D models of parts and use those models to create a cheaper and faster way to manufacture parts. Today, the majority of investment casting is done through three processes: lost wax casting, sand casting, and investment casting.

Investment casting is a process where a part is cast (or formed) in sand or resin that is partially solid and partially liquid. This type of casting is often used to create smaller, fast-moving parts that would be difficult or impossible to machine. Investment casting is sometimes referred to as a sand casting. This process requires sand or other material that can be moulded into the shape of the part to be cast. In the manufacturing process, it uses a mould to create a part from a liquid alloy. The part is then finished and painted just like a part made from another manufacturing process, such as machining or injection moulding. The main advantage of investment casting is that it’s a fast way to produce complex, high-quality parts. The process works best for parts with complex shapes and those that will be painted.

Types of Investment Casting

Investment casting is a manufacturing process used to create objects out of metal. The process involves melting metal, pouring the metal into a mould, and then curing the metal to create the finished product. The shape of the finished product is determined by the type of metal and the shape of the mould. The most common types of investment casting include sand casting, lost-wax casting, and investment mould casting. Other also considers, Stainless Steel Casting, Aluminum Casting, Carbon Steel Casting, Brass Casting, Bronze Casting. Cobalt Casting, Tool Steel Casting, Metal Casting, and Rapid Prototype Casting. These are all helpful in the industry and perform a role depending on the needs of the client that will invest in the casting process.

Advantages and Disadvantages of Investment Casting


Investment casting is a type of metal casting that uses sand, cement, and other materials to create moulds for casting metal into objects. These objects can range from simple hollow vessels and figurines to complex engine parts and machinery. The metal casting process is much faster and more economical than the traditional method of machining metal parts. The material cost of investment casting is significantly less than the material cost of machining.


We all know that investment casting is a process used to create metal parts from a liquid or mass of molten material. The metal is poured into a casting cavity, where it cools and solidifies to become a part. The part can then be machined, which would have been much more difficult if the part had been made from a solid material. However, this process has several disadvantages. Such as high cost in large production runs, parts are less complex it lower dimensional accuracy and the surface finish requires additional work

Investment Casting Materials

Investment casting is a manufacturing process used to create objects out of metal. The term “investment” refers to the material used to create the object – the “casting” part of the process. The majority of investment casting objects are made from bronze. However, investment casting can also be used to create objects from a variety of different materials, including copper, lead, zinc, nickel, silver, gold, and even plastic. Some of the most common investment casting materials are plaster, silicone, and urethane. Other materials can be used as well, such as fiberglass and wax. There are a number of different ways to cast an object, but the most common is to use plaster of Paris.

Investment casting applications

When we talk about investment casting the simple understanding of it is the process of creating a metal part by injecting molten metal into a mould made of sand, which hardens into a shape that can be used to make products or parts. The material is often used to create small and intricate parts that would be difficult to make using other manufacturing processes. Investment casting can be used to make parts that are used in a wide variety of products, such as engines, plumbing fixtures, and small machine parts. Investment casting became an enabling technology in most industries today, their applications include: Aerospace and defense, Power Generation, Automotive, Oil and gas, Space exploration, Medical/orthopedics, Agriculture, Construction

Commercial and consumer products.

When to use investment casting

There are many reasons why investment casting is a better choice than other metalworking methods. For example, when it comes to small, intricate metal parts, nothing beats the precision of investment casting. You can also create metal parts that are much larger than you would be able to make using other metalworking methods. Investment casting is a metal forming process that uses wax patterns to create metal parts. It’s a great choice for making small and intricate parts that might be difficult to machine, or for making large parts that would be too costly to make using other methods. It’s also a great choice for when you need to make a lot of parts quickly because you can cast many parts at once in a single pour. It also offers a lot of design flexibility, because you can build up complex shapes using multiple layers of metal.
