High Quality Auto Part Investment Casting

Mingda provides high-quality custom ferrous and non-ferrous Investment Casting parts and components for a wide range of industries. Investment casting is a very versatile process which is ideal for simple or complex, low or high volume production. We produce investment castings with material such as stainless steel, duplex stainless steel, titanium, carbon steel, tool steel, and aluminum alloys etc. Weight range from a few grams to almost one metric ton. We also provide a broad range of secondary service including machining, surface finishing etc.

What Is Investment Casting?

Investment casting refers to the formation of ceramics around a wax pattern to form a shell for casting molten metal. Once wax patterns are created, they are melted into the gate system, immersed in slurry and sand to form a layered shell, and then replaced by molten metal such as stainless steel, aluminum, or the like.

How are Investment Castings Made?

Investment casting involves creating an original wax model, building the image with plaster and successive layers until a strong shell surrounds the model. After melting the wax, pour the molten gold or bronze into the mold to create a perfect replica of the original wax pattern. Investment casting provides economical undercutting, high resolution, sophisticated detail and smooth surface finish compared to machining separations. In most cases, investment casting is the only way the part can be made economically.

Linear Tolerance of Investment Casting

Normal linear tolerances of investment casting are as follows as a general rule: Up to 1" +/- .010", for each additional inch up to ten inches +/- .003" per inch. For dimensions greater than ten inches allow +/- .005" per inch. Secondary operations such as straightening and sizing will produce closer dimensional tolerance.
