What do you mean by investment casting?

Investment casting is a casting process in which a mold is made around a wax pattern that is burned away when the molten material is poured in. In investment casting, a ceramic slurry is applied around a disposable pattern to form a mold.

What is the process of investment casting?

The Investment Casting process, also known as ‘Lost Wax Casting’ is a developmental manufacturing process that converts molten metal in a single operation to precision, engineered components with minimum wastage of material, energy and subsequent machining.

What can investment casting be used for?

Investment casting is generally used for making complex-shaped components that require tighter tolerances, thinner walls and better surface finish than can be obtained with sand casting. The distinguishing feature of investment casting is the way the mould is made.

What is investment casting and its application?

Investment casting is used in the aerospace and power generation industries to produce turbine blades with complex shapes or cooling systems. Blades produced by investment casting can include single-crystal (SX), directionally solidified (DS), or conventional equiaxed blades.

What is another name for investment casting?

Investment casting, also known as precision casting or lost-wax casting, is a manufacturing process in which a wax pattern is used to shape a disposable ceramic mold.

What are the types of investment casting?

Investment Casting

• Stainless Steel Casting.
• Carbon Steel Casting.
• Metal Casting.
• Rapid Prototype Casting.

What is casting and its process?

Casting is a manufacturing process by which a molten material such as metal or plastic is introduced into a mold, allowed to solidify within the mold, and then ejected or broken out to make a fabricated part.

What are types of casting?

10 Different Types of Casting Process

• （1）Sand casting.
• （2）Investment casting.
• （3）Die casting.
• （4）Low pressure casting.
• （5）Centrifugal casting.
• （6）Gravity die casting.
• （7）Vacuum die casting.
• （8）Squeezing die casting.

Why it is called investment casting?

Investment casting is a centuries-old casting process that centers around lost-wax casting. It involves coating a wax mold with a liquid material. It’s called “investment casting” because the mold pattern used in this casting process becomes “invested” with the liquid refractory material.

Is casting permanent?

Permanent mold casting is a metal casting process that employs reusable molds (“permanent molds”), usually made from metal. A variation on the typical gravity casting process, called slush casting, produces hollow castings. Common casting metals are aluminium, magnesium, and copper alloys.

How accurate is investment casting?

Investment casting can achieve excellent detail and accuracy – in +/- 0.005 inch per inch range. Very little additional machining is necessary for details and features.

Can casting investment be reused?

Depending on the application, investment casting can be suitable for both short and long production runs, and can produce several hundred products at a time. Wax and ceramic materials can be reused throughout the investment casting process.

Why is wax used in investment casting?

Runner wax blends are used by investment casting companies when desiring exceptional mechanical strength and lower viscosity. This type of wax has a lower melting point than pattern waxes. So it will drain completely out of the ceramic mold during the dewaxing process without the need to use higher temperatures.

What is investment material?

Investment materials are used to make a mold into which the liquid metal can be poured during the casting process. Such a material thus needs a binder that can bind heat resistant particles together and form an investment material.
