Different Types of Shell Making for Investment Casting

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...

Heat Treatment of Stainless Steel Castings in American Standard

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...

Common Questions About Investment Casting

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...

Advantages and Disadvantages of Sand Casting

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 of Stainless Steel Castings

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...

The Role of Each Common Element in Stainless Steel Castings

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...

Castability of Cast Steel

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...

Cast Steel Pouring in Investment Casting

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.

What Functional Departments Should a Foundry Have?

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...

Spheroidizing Treatment of Nodular Cast Iron

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.

The Characteristics of Castings with Different Metal Alloys

Many customers have asked us how to choose a casting alloy. Different casting alloys have different properties and structural characteristics. In the stage of casting process design, engineers must consider the characteristics of diffe...

Steel Casting vs Other Alloy Casting

Steel castings are preferentially used in these situations: parts subject to high tensile stress or dynamic load, important pressure vessel castings, parts subject to larger loads at low or high temperatures and other key components. ...
