Focusing on special parts
Investment casting, also known as lost-wax casting, is a highly precise and versatile manufacturing process that has been refined over centuries. This method involves creating a detailed wax model of the desired part, which is then encased in a ceramic shell. Once the wax is melted away, molten metal is poured into the mold to form the final component. Renowned for its ability to produce intricate and complex shapes with exceptional accuracy and surface finish, investment casting machining is a preferred choice in industries such as aerospace, medical devices, automotive, and more. Discover how investment casting can meet your high-precision manufacturing needs and deliver superior results.

Automotive: Engine components, Transmission parts, Suspension components, Brake systems
Medical Devices: Surgical instruments, Dental implants, Prosthetic components
Jewelry: Fine jewelry pieces, Custom jewelry designs
Industrial Components: Valves Pumps, Gears Precision tools
Pattern Creation: A pattern is made from wax or another meltable material. This pattern is coated with a refractory material to form the mold shell.
Coating: The pattern is dipped in a refractory slurry and then sprinkled with fine sand, creating a sturdy outer shell. This process may be repeated multiple times to achieve the desired thickness and strength of the shell.
Wax Removal: The coated mold is heated to melt and remove the internal wax pattern, leaving a hollow cavity.
Pouring: Molten metal is poured into the cavity, filling the mold shape. The metal cools and solidifies, forming the desired part.
Shell Removal: The refractory shell is broken or removed to extract the cast metal part.
Post-Processing: The castings undergo machining, cleaning, and surface finishing to achieve the required dimensions and surface quality.
High precision investment casting, also known as lost wax casting, is a manufacturing process used to create intricate and complex metal parts with high levels of accuracy and detail. The process begins with the creation of a wax pattern, which is then coated with a ceramic shell to form a mold. The wax is then melted out of the mold, leaving behind a cavity in the shape of the desired part. Molten metal is then poured into the cavity, filling the space and taking on the shape of the mold. Once the metal has solidified, the ceramic shell is broken away, revealing the final metal part. This method allows for the production of parts with very tight tolerances and fine surface finishes, making it ideal for applications in industries such as aerospace, automotive, and medical.
