The foundry industry is one of the basic industries of the entire industry. Casting plays an increasingly important role in the field of modern machinery. Many metal forming parts cannot be manufactured without casting.

Nickel-based alloys have high strength and good oxidation resistance, corrosion resistance and high temperature resistance in the range of 650 to 1000°C. Nickel-based alloy is a common high-temperature resistance alloy.

As a precision casting process, the shell making is a very critical process during investment casting. The quality of the shell is directly related to the roughness and dimensional tolerance of the final casting. Therefore, it is an i...

Stainless steel is a commonly used alloy in precision investment casting. Because stainless steel has excellent properties such as corrosion resistance and oxidation resistance, stainless steel castings are also widely used in various...

Investment casting, which is also known lost wax casting or precision casting, refers to the formation of ceramic around the wax patterns to create a multi or single part mold to receive molten metal. This process utilizes an ex...

Sand casting takes advantage of sand's inherent compactability, refractory nature and recyclability to produce relatively inexpensive molds. Sand casting requires a relatively low investment and allows for quick tooling development ...

Solution heat treatment is generally used for stainless steel castings. Its main purpose is to dissolve carbides or other precipitated phases in the stainless steel in solid solution so as to obtain a supersaturated single-phase structur...

For stainless steel castings, each chemical composition plays a different role on the corrosion resistant performance and mechanical properties. Here in this article we try to introduce the role of each common element in stainless...

Generally speaking, the casting performance of cast steel is worse than that of cast iron. The fluidity of cast steel should be low, so it is easy to form a cold barrier. The oxidation and gas absorption of cast steel is also relativ...

For the investment casting foundry, pouring is an very important step during casting process. This article introduces the shell pre-heating, shell temperature, liquid cast steel pouring temperature and the pouring speed.

A foundry is a professional factory specializing in the production of various metal castings. Different foundries have their own casting processes, such as sand casting, investment casting, shell molding casting, lost foam casting, v...

The spheroidization rate is an important index of ductile iron castings. The spheroidizing agent (Nodulizer) is an additive added to the liquid cast iron in order to make the graphite crystal in the nodular cast iron become spherical.
