Investment casting, Precision casting

Lost wax casting, also known as investment casting, is a precision casting process used to create intricate and detailed metal parts or components. This method has been employed for centuries and is renowned for its ability to produce complex shapes with high accuracy and fine surface finishes. The process contains pattern creation, assembly, investment, de-waxing, casting, cooling and finishing.


There are several benefits of Lax Wax Casting that make it a preferred method for producing intricate and high-quality metal parts:

Accurate dimension: Lost wax casting delivers high dimensional accuracy and tight tolerances, ensuring that the final cast parts match the exact specifications of the original pattern.

Versatility in Materials: It can work with a wide range of metals and alloys, including steel, stainless steel, aluminum, bronze, and more, offering flexibility in material selection based on specific application requirements.

Customization and Complexity: The process enables the production of highly complex shapes and fine details that might be challenging or impossible to achieve with other casting methods. At the same time, it allows for the creation of customized parts in small to large production runs, catering to diverse industrial and artistic needs.

Low Production Costs and Processing Time: Lost wax casting often produces near-net shapes, minimizing material waste and reducing the need for additional machining, which can lower production costs and processing time.

Lost-wax casting finds applications across multiple industries due to its ability to create intricate and high-quality parts, including:
Aerospace industry, automotive sector, medical equipment, art and jewelry, industrial equipment, firearms and defense, power generation machinery, and general manufacturing.
