Turbine Blade Casting: Investment Casting Perfect Blades

Turbine Blade Casting is widly use in various industry sectors.

Upon its application, the Blade Casting always produce through sand casting process, investment casting process and die casting process.

Sand casting process offer the lager scale Turbine Blade Casting purpose, it offers advantages such as relatively lower cost for certain production volumes. The process is suitable for producing blades with less complex geometries where the precision requirements are not extremely high. However, it may require additional machining to achieve the final dimensions and surface finish.

Investment casting process more suitable for high precison and high surface finish quirements. It is highly favored for Turbine Blade Casting production.

Die casting can also be considered for turbine blade casting in specific cases. This process enables high – volume production with good dimensional accuracy. However, it may be more challenging to use for some of the more complex and heat – resistant materials used in turbine blades.

Investment casting Services , also known as lost wax casting, is a casting method in which a pattern is made of a melt-able material, then coated with several layers of refractory material to form a shell, and the pattern is melted away after high-temperature firing, and then the molten metal is poured into the shell.

Investment casting have high precision and high surface quality, with small machining allowances, which can achieve less or no machining requires. Investment casting can cast complex thin-walled parts with complex shapes (the minimum wall thickness can reach 0.25-0.4mm), and the smallest hole diameter can reach 2.5mm.

The process normal as below:

Drawing Review ->Tooling Designing ->Tooling Manufacturing ->Wax Pattern Making ->Pattern Tree Assembly ->Dipping and Coating ->De-waxing and Firing- Pouring-Knockout ->Grinding ->Heat Treatment -> Machining(if requires) ->Inspection->Delivery
