What Is Investment Casting?
Investment casting, also known as lost wax casting and precision casting. With high accuracy and repeatability, investment casting has been used for thousands of years.
Process of Investment Casting:
- Wax Pattern Injection
- Pattern Assembly
- Shell Making
- Dewaxing
- Metal Pouring
- Shell Removal
- Cutting Off
- Finished Casting
Components with excellent mechanical properties and tight tolerance delivered by investment casting make them ideal parts for various demanding industries, including aerospace, automotive, pump, valve, and more.
Benefits of Pingheng Machinery Investment Casting

Investment casting allows for a casting accuracy of +0.005 inch.
Smooth finishes are the forte of investment casting.
Investment Casting Dimensional Tolerance
If your project has strict tolerance demands, our investment casting process is your best choice.
General casting tolerances we can achieve are CT6 to CT8. For small-sized castings or localized areas within castings, our casting tolerances can achieve CT4.
Please send your drawing & requirements, and we will provide a satisfactory response.
Rapid Prototype Casting
As a one-stop investment casting foundry, Pingheng can adjust our workflow flexibly, transforming your drawings into prototype samples with excellent detail and accuracy. Although Pingheng’s general rapid prototype casting has greatly saved time, for extremely urgent orders, our in-house 3D prototyping is your antidote. Compared to conventional wax patterns, 3D wax patterns can be put into production directly, which further reduces your time.
Investment Casting Tooling & Fixture Fabrication
Tooling development is a critical stage in investment casting, as it directly influences the quality of the final products. For parts requiring additional machining, custom-designed fixtures are used to securely hold castings during secondary operations. As an integrated investment casting manufacturer in China, we have a professional tooling & fixture fabrication team to design and produce our own molds and fixtures. This vertical integration allows us to maintain strict control over every step of the process, ensuring superior product quality and reliable performance.
Investment Casting CNC Machining
Pingheng Machinery has complete machining equipment. With 40 CNC lathes, 38 CNC machining centers, 5 tapping machines, 22 bench drills, and years of experience in precision CNC machining, Pingheng provides advanced CNC manufacturing services. Our professional CNC programmer will examine the details of each part, including tolerance, profile, and surface finish, formulating specific control for each part.
