The Role of Investment Casting in Complex Metal Part Production

The role of investment casting in the production of complex metal parts:

High precision molding:

By replicating complex structures through wax molds, a tolerance of ± 0.1mm is achieved to meet the precision requirements of aerospace, medical and other fields.

Complex geometric adaptability:

Capable of casting thin-walled (<1mm), deep holes, irregular surfaces, and multi cavity parts, supporting integrated molding and reducing assembly steps.

Wide material compatibility:

suitable for difficult to machine materials such as stainless steel, titanium alloys, and high-temperature alloys, while also considering high strength, corrosion resistance, and high temperature resistance.

Excellent surface quality:

The surface smoothness of the casting reaches Ra 3.2 μ m or above, reducing subsequent precision machining costs.

Small batch efficient production:

Suitable for prototype development or small to medium batch customization, shortening the manufacturing cycle of complex parts and achieving significant economic benefits.

Application of Investment Casting in Practical Production

Investment casting (lost wax casting) is a precision molding process widely used in aerospace, medical, automotive, and art manufacturing fields.

It replicates complex structures through meltable wax molds and is suitable for producing high-precision, thin-walled, or finely shaped metal components such as turbine blades, orthopedic implants, engine parts, etc.

This technology can process difficult to form materials such as high-temperature alloys and titanium alloys, with high surface smoothness of the finished products, reducing subsequent processing costs.

It accounts for over 60% of the aerospace industry and is the core process for manufacturing high-temperature resistant turbine components; Used in the medical field for customized artificial joints; The automotive industry is used for the production of precision gears and sensor housings.

In recent years, the combination of 3D printing wax mold technology has further improved the manufacturing efficiency of complex components.
