Inconel 718 Casting
What is Inconel 718 Casting
Inconel 718 casting is a specialized manufacturing process for high-performance nickel-based superalloy components. This superalloy contains 50-55% nickel, 17-21% chromium, 4.75-5.5% niobium, 2.8-3.3% molybdenum, and iron plus other trace elements, making it exceptional for high-temperature and corrosion-resistant applications.
The casting process for Inconel 718 typically employs investment casting (lost wax process), as it enables the production of complex geometries with excellent surface finish and dimensional accuracy. The process requires precise control of temperature and cooling rates to achieve optimal mechanical properties and microstructure.
This advanced casting method is extensively used in aerospace components, industrial gas turbines, nuclear reactors, and chemical processing equipment, where components must perform reliably under extreme conditions ranging from -257°C to 704°C (-432°F to 1300°F) and in corrosive environments.

We Provide Casting Services Include:
Minghe Casting services working with sand casting, metal casting, investment casting, lost foam casting, and more.
Sand Casting
Sand CastingSand Casting is a traditional casting process that uses sand as the main modeling material to make molds. Gravity casting is generally used for sand molds, and low-pressure casting, centrifugal casting and other processes can also be used when there are special requirements. Sand casting has a wide range of adaptability, small pieces, large pieces, simple pieces, complex pieces, single pieces, and large quantities can be used.
Permanent Mold Casting
Permanent Mold CastingPermanent Mold Casting have a long life and high production efficiency, not only have good dimensional accuracy and smooth surface, but also have higher strength than sand castings and are less likely to be damaged when the same molten metal is poured. Therefore, in the mass production of medium and small non-ferrous metal castings, as long as the melting point of the casting material is not too high, metal casting is generally preferred.
Investment Casting
Investment CastingThe biggest advantage of investment casting is that because investment castings have high dimensional accuracy and surface finish, they can reduce machining work, but leave a little machining allowance on the parts with higher requirements. It can be seen that the use of investment casting method can save a lot of machine tool equipment and processing man-hours, and greatly save metal raw materials.
Lost Foam Casting
Lost Foam CastingLost foam casting is to combine paraffin wax or foam models similar to the casting size and shape into model clusters. After brushing and drying refractory coatings, they are buried in dry quartz sand for vibration modeling, and poured under negative pressure to gasify the model. The liquid metal occupies the position of the model and forms a new casting method after solidification and cooling.
Die Casting
Die CastingDie casting is a metal casting process, which is characterized by applying high pressure to the molten metal using the cavity of the mold. Molds are usually made of higher-strength alloys, and this process is somewhat similar to injection molding. Most die castings are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Minghe has been China's top die casting service since 1995.
Centrifugal Casting
Centrifugal CastingCentrifugal Casting is a technique and method of injecting liquid metal into a high-speed rotating mold, so that the liquid metal is centrifugal motion to fill the mold and form a casting. Due to the centrifugal movement, the liquid metal can fill the mold well in the radial direction and form the free surface of the casting; it affects the crystallization process of the metal, thereby improving the mechanical and physical properties of the casting.
Low Pressure Casting
Low Pressure CastingLow Pressure Casting means that the mold is generally placed above a sealed crucible, and compressed air is introduced into the crucible to cause a low pressure (0.06～0.15MPa) on the surface of the molten metal, so that the molten metal rises from the riser pipe to fill the mold and control solidified casting method. This casting method has good feeding and dense structure, easy to cast large thin-walled complex castings, no risers, and a metal recovery rate of 95%. No pollution, easy to realize automation.
