Investment casting, also known as the lost-wax casting process, is a precision metal casting method used to manufacture components with complex geometries, fine details, and controlled dimensional accuracy. In this process, a wax pattern replicating the final component is produced and coated with multiple layers of ceramic slurry to form a rigid shell. The wax is then removed, and molten metal is poured into the resulting cavity to produce a near-net shape casting with minimal post-processing requirements.
This casting process offers advantages over conventional methods by enabling improved dimensional control, enhanced design flexibility, and the production of intricate shapes that are difficult to achieve through other manufacturing techniques. Due to these capabilities, investment casting is widely used in industries such as aerospace, automotive, industrial machinery, and other applications where precision and reliability are critical.
Investment casting supports a broad range of materials, including ferrous, non-ferrous, and special alloy grades, allowing components to be tailored to specific mechanical, thermal, and corrosion-resistance requirements. The ability to achieve near-net shapes also helps reduce machining effort, material waste, and overall production costs.
Today, investment casting remains a well-established and reliable manufacturing solution for producing precision-engineered metal components. At Gorecha Metal, disciplined process control, material expertise, and systematic quality assurance ensure that every casting meets defined technical, quality, and performance requirements.
Ideal for achieving superior accuracy, design flexibility, and efficiency, investment casting has become a preferred choice across industries. This high-precision casting process offers a competitive edge in quality and performance, delivering components that meet the most demanding standards.
Investment casting excels in capturing intricate details and complex geometries, offering limitless design possibilities. This flexibility enables the production of components that would be difficult or impossible to achieve with other casting methods.
The lost-wax casting process yields near-net shape parts with extremely tight tolerances. This superior accuracy ensures that every component meets stringent specifications and requires minimal post-production finishing.
The investment casting process produces a smooth, refined surface finish that often eliminates the need for extensive machining. The result is components that are both aesthetically pleasing and functionally optimized.
Investment casting supports a wide range of materials—from ferrous and non-ferrous metals to specialized exotic alloys—allowing for the creation of components tailored to diverse industrial applications and performance requirements.
Rigorous quality control and advanced process management ensure that each casting consistently meets high industry standards, delivering reliable, high-performance components for critical applications.
By reducing the need for secondary machining and optimizing manufacturing processes, investment casting offers significant cost savings, making it an attractive option for both low-volume and high-volume production runs.
The investment casting process is a time-tested sequence of precision steps that transforms innovative designs into high-performance, reliable components. From the initial creation of detailed wax patterns to the final rigorous quality checks, our process marries traditional craftsmanship with advanced technology to consistently deliver near-net shape castings that meet global standards.
The investment casting process begins with pattern making, where molten wax is injected into a precision-machined die. After cooling and solidification, the wax pattern takes the exact shape of the final component. This stage is critical, as dimensional accuracy and surface finish of the final casting are largely determined by the quality of the wax pattern and the tooling used.
Individual wax patterns are assembled onto a central wax runner system to form a wax tree. This assembly allows multiple components to be cast in a single pour and ensures controlled and uniform metal flow during casting. Proper design of the sprue and gating system helps minimize turbulence, shrinkage defects, and material wastage.
The wax tree is coated with a ceramic shell by repeatedly dipping it into a refractory slurry and then applying stucco sand. Each layer is dried under controlled conditions before the next coating is applied. This process is repeated several times until the shell reaches the required thickness and strength to withstand high-temperature metal pouring.
Once the ceramic shell is fully built and dried, the wax is removed through a dewaxing process. The shell is placed in an autoclave or furnace, where the wax melts and drains out, leaving behind a hollow cavity inside the ceramic mold. This step gives the process its name, “lost wax casting.”
After dewaxing, the ceramic shell is fired at elevated temperatures to remove any remaining wax residue and moisture. Firing also increases the mechanical strength of the shell. Preheating the mold before pouring helps prevent thermal shock and ensures smooth metal flow during casting.
The selected metal alloy is melted in a furnace and brought to the required pouring temperature. The molten metal is then poured into the preheated ceramic shell, either by gravity or with vacuum assistance, depending on the component design and quality requirements. This step fills the mold cavity with molten metal, replicating the exact shape of the wax pattern.
After pouring, the molten metal is allowed to cool and solidify within the ceramic shell. Cooling conditions are controlled based on the material and component geometry, as this stage directly affects the microstructure, mechanical properties, and soundness of the casting.
Once the metal has fully solidified, the ceramic shell is removed using mechanical vibration, hammering, or blasting methods. This operation exposes the metal castings, which are still attached to the central sprue system.
The individual cast components are separated from the sprue by cutting operations. Gates, runners, and excess material are removed, and initial surface cleaning is carried out. This prepares the casting for subsequent finishing and inspection stages.
Depending on the material grade and application, the castings may undergo heat treatment to achieve the desired mechanical properties such as strength, hardness, or ductility. The heat treatment cycle is selected as per material standards and customer specifications.
Finishing processes such as shot blasting, grinding, polishing, or buffing are performed to improve surface finish.
The final stage involves thorough inspection and quality checks. Castings are evaluated through visual inspection, dimensional measurement using gauges or CMM, and non-destructive testing if required. Mechanical and chemical tests may also be conducted to ensure compliance with customer and industry standards before dispatch.
We work with various material grades, including Carbon Steels, Stainless Steel Variants, Duplex Stainless Steels, Super Alloys, and an entire range of EN-series, complying with national and international standards like IS, BS, ASTM, DIN, JIS, EN, etc.
