Product Details


Key Specifications/Special Features:


Investment casting is an industrial process based on and also called lost-wax casting, one of the oldest known metal-forming techniques
From 5000 years ago, when beeswax formed the pattern, to today’s high-technology waxes, refractory materials and specialist alloys, the castings allow the production of components with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys
Process is generally used for small castings
Generally more expensive per unit than die casting or sand casting, but has lower equipment costs
Can produce complicated shapes that would be difficult or impossible with die casting, yet like that process, it requires little surface finishing and only minor machining
Investment casting is used in 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
Investment casting is also widely used by firearms manufacturers to fabricate firearm receivers, triggers, hammers, and other precision parts at low costs
Other industries that use standard investment-cast parts include military, medical, commercial and automotive
