China precision casting, lost wax casting, steel casting foundry
Investment casting is a near shape casting process, which can achieve complicated thin-walled casting products. There are two main different levels of investment casting process. The high demanding investment casting process is applied in aerospace industry. The typical investment cast aerospace product is the thin wall turbine blade. And the other common investment casting is used for common industries which don't have extra thin wall and complicated structure.
Cinda investment casting foundry is a common steel precision casting foundry specializing in low carbon steel, stainless steel and alloy steel casting. We can use three different investment casting processes for different kinds of steel precision castings. Most of our steel precision casting products are common machinery parts.
Investment casting is one of the oldest known metal-forming techniques. Five thousand years ago, people used beeswax to form the casting pattern, while today we use high-technology waxes like silica sol or acetic acid resin. And now lots of refractory materials and specialist alloys can be applied for investment casting process to produce components with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys.
A well known modern form of investment casting is lost foam casting which eliminates certain steps in the process. It is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of foam to simplify the investment casting process by removing the need to melt the wax out of the mold.
Investment casting is used in the aerospace and power generation industries to produce turbine blades with complex shapes or cooling systems. Blades produced by investment casting can include single-crystal, directionally solidified, or conventional equaled blades. It 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.
There are various kinds of value added service for steel investment castings, such as heat treatment, mirror polishing, electroplating, electrophoresis, powder coating, and painting. Compared with other kinds of post treatment, heat treatment can be the most impressive one for steel investment casting products.
