Summary of Electric Valve Standards
Introduction
Electric valves, also called solenoid valves, are electromechanical devices that use electrical signals to actuate their function. When an electric valve is energized by an electrical signal, it opens, allowing fluid to flow through the system. When it is de-energized, the valve clos......
Metal type equipment: hot chamber die casting machine
Introduction
Hot chamber die casting machine (HCDM) is a type of metal casting process that is primarily used to produce castings that have highly accurate dimensions, as well as excellent surface quality. This process is typically used to manufacture parts that require intricate details and comp......

Austenitic Stainless Steel - Heat Treatment
Austenitic stainless steel is a unique group of metals due to its high chromium (Cr) and nickel (Ni) content and its ability to form a very hard, ultra-durable surface when exposed to high temperatures. It is used in many applications due to......
Surface tension measurement
？
(A) Introduction
Surface tension is one of the fundamental physical properties of any substance. It is an important factor in the design and manufacture of a variety of products, including beverages, cleaners and pharmaceuticals, as well as in predicting the behavior of many liquids in contact ......
Nitriding of Steel (Gas Nitriding)
Nitriding of Steel
Introduction
Steel has been used as an essential material in a wide range of industrial applications. It is especially important in the manufacture of components used in heavy engineering and other industries, where it is expected to be highly durable and reliable. As such, it......
gas flux
Gas brazing is a process of joining two metallic workpieces by melting a non-ferrous filler metal between them at high temperatures. It is similar to arc welding but without the use of arc. Instead, a flame, a laser-beam, or an electric resistance is used to heat the parts until the filler metal m......

Hot Corrosion
Introduction
Hot corrosion is a form of corrosion that occurs when certain conditions are present. It is an aggressive form of accelerated corrosion caused by combining high temperatures (313-843 K) and water or moisture within the atmosphere, often containing......
Tempering process of foundry and die steel
Hardenability of Steel
Hardenability is an important characteristic of steel that is used in the manufacture of forging and mold steel components. It is defined as the ability of the steel to obtain a hardness greater than that of untreated steels of the same carbon content when quenched from an ......
Main properties and application examples of cast aluminum bronze
Introduction
Aluminum bronze is essentially a brass, a mixture of copper with up to 15% of aluminum. This metal is incredibly strong and resistant to corrosion. Though aluminum bronze is one of the most expensive bronze alloys, the advantages it provides make it an ideal metal for bearing and ot......
