ductile iron hydraulic valve casting
Investment castingis an industrial process based on and also calledlost-wax casting, one of the oldest known metal-forming techniques.From 5,000 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
The process is generally used for small castings. It is generally
more expensive per unit than die casting or sand casting, but has
lower equipment costs. It 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 custom casting is used in theaerospaceandpower generationindustries 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 cost. Other industries that use
standard investment-cast parts include military, medical,
commercial and automotive.
