Precision investment casting-Overview of Investment Casting Parts

Precision investment casting, also called lost-wax casting, is an industrial process that produces investment casting parts in a wide range of speedy prototyping supplies.

Precision investment casting generates casting parts with high accuracy, strong tolerances and continuous precision. This investing casting method gives superior quality results in a wide range of metals and high-performance alloys.

Intricately designed castings are feasible with this precision casting process.
The process of investment casting can be applied to almost any metal or alloy.
The process is also used with most commons metals such as aluminum, copper alloys and steels.

The common issue of metal porosity is not as difficult to overcome when creating investment casting parts. Sluggish rates of solidification and low mechanical properties make porosity controllable with proper quality precision casting techniques. Select ISO 9001:2008 certified precision investment casting manufacturers such as Shelmet Precision Castings, Inc that adhere to certified best business tactics and quality casting standards.

Intricately designed investment casting parts are often produced in large quantities with tight tolerances that do not require detailed machining. This casting process is used to produce precision investment casting parts because of its efficiency of fabricating wall surfaces as thin as 0.50 mm.

The process of investment casting is normally used for small castings. On the contrary nowadays investment casting parts are widely used in the aerospace industry in larger sizes such as entire aircraft doorframes. The power generation industry makes large turbine blades using investment casting. Investment casting parts are so varied they have become standardized in the firearms industry as receivers and triggers. Other industries where standardized investment casting parts are common are military, medical and automotive industries, although the versatility and rapid prototyping benefits make this method a perfect option in most industries.

Investment casting is normally more costly per unit in comparison to die casting or sand casting. However, equipment costs are much lower to create investment casting parts. One can think of producing complex shapes using investment casting which is hardly possible with die casting. In investment casting, plaster molds and flexible patterns of wax or other fusible substance are most commonly used. Due to use of wax, it is called lost-wax casting. For several castings, plaster slurry is used around patterns. The patterns are melted out once the plaster is baked.

You'll find several advantages of investment casting which include:
· Excellent surface finishing
· High-dimensional precision
· Even exceptionally complicated parts are also castable
· A wide range of metal can be cast
· No need of flash

Investment casting is also ideal for small components and it is particularly suitable for the production of jewelry and precision instruments of small sizes.

The aerospace industry uses the investment casting process in many large and small applications. This has opened up a new arena for the investment casting process and improved technology has become imperative to produce premium quality castings.

Combining exact dimensional control with highly sophisticated technology produces high quality investment casting parts developed at low cost. Visit shelmetcastings.com and explore the finest prrecision casting services.
