The Application of Lost Wax Investment Casting

A wide variety of parts, products and assemblies are produced using lost wax investment casting or investment casting. The precision and accuracy of the technology make it ideal for producing thin-walled, intricately detailed and close tolerance parts. Industries that use lost wax investment casting to produce parts include aerospace, medical treatment, robotics, military manufacturing and automobile.

1. Lost wax investment casting is used in aerospace and automobile

Lost wax investment casting is essential in the construction of aircraft and spacecraft. Parts produced by lost wax investment casting can be found in every part of space and commercial aircraft, from the bearings that open the doors to the basic components of the engine.

The automotive industry relies on lost wax investment casting to produce engine components, compressor components and transmission components. Aluminum lost wax castings are used for the space frame and suspension system, while stainless steel castings are used for the fuel gate. Other vehicle components include drive and powertrain components, fuel systems and convertible tops. Parts are made of ferrous and non-ferrous metals, which are especially suitable for the application. The benefits of using lost wax casting China in automotive manufacturing include excellent metal lubrication and wear resistance.

2. Lost wax investment casting is used in petroleum industry and chemical industry

Due to the nature of oil and gas drilling, parts made by lost wax investment casting for the oil industry must have unique qualities. The oil and gas industry is operated in some of the harshest environments in the world, which places high demands on the parts required. Parts produced using the lost wax investment casting technology require excellent wear and corrosion resistance. Gate valves, pipe handlers, lift parts, valve brackets, sliding links and locking rods are all fabricated using lost wax investment casting. The main metals are aluminum, stainless steel and alloy steel.

The biggest problem facing the chemical industry is corrosion and erosion, which can seriously affect the mechanical properties of the components it uses. For worker safety, parts produced for this industry must be able to withstand extreme temperature and pressure. Parts produced using lost wax investment casting must be able to withstand temperatures between 1700°F and 2000°F.

3. Lost wax investment casting is used in the food industry

Applications for food industry components range from harvesting wheat and food ingredients to processing and bottling of canned food or soft drinks. Some of the parts produced using lost wax investment casting include meat slicers, various poultry processing tools, ice maker parts, and food preparation racks and grills. Products for the food industry are designed to withstand acidic chemicals in food and have excellent strength and reliable performance.
