investment casting application & size limits

[Allen Young]

What is investment casting used for? And what are the limitatons of investment casting?
Investment casting creates exact components with the least amount of waste, energy, and subsequent machining. It can also guarantee the manufacture of extremely complex parts. As a result, design engineers will find the investment casting method quite valuable.

Size Limitations: Investment castings can be made in a variety of sizes. That range has a limit, which is lower than other shaped methods like sand casting.
Investment casting is a great alternative for thin-walled applications, however very small internal designs that require cores might be difficult to work with. Holes can’t be any smaller than 1/16″ (1.6mm) in diameter or any deeper than 1.5 times the diameter.

Investment Castings’ Most Common Uses
Investment castings can be used in a variety of ways. These metal components are used the most in the aerospace, power generation, firearms, automotive, military, commercial, food service, gas & oil, and energy industries. Cast parts are used in the guns industry for receivers, triggers, hammers, and other precise parts. Even beverage industry equipment makers and worldwide pressure relief valve manufacturers in the oil and gas industry employ investment castings. As a result, regardless of your industry, if your company can profit from the advantages of investment cast parts and components, they could be the ideal metal choice for any and all of your projects.

Investment casting now holds the top position in the casting sector thanks to jet propulsion for both military and commercial aircraft. This casting technology is employed in a wide range of high-tech industrial applications, including massive castings of 300 kg and small castings of 30 kg. In terms of casting processes, this approach is more expensive than sand casting, although the equipment is considerably less expensive. However, investment casting continues to be primarily used for complex designs that cannot be cast using any other technique. In spaceships, jet engines, etc., investment casting is used extensively. Despite being largely dependent on the aircraft industry, this sector is finding that our new field of application is helping it to expand its horizons.
