Hebei Yogem Castings Co., Ltd

As a   Casting Supplier , I take you through die casting. Die casting is used to produce a wide range of products that can be found in almost any industry or vertical you can think of. As with any other metal manufacturing process, die cast products are only as good as the metal used in their production. The source metal will affect the overall quality, durability and aesthetic appearance of the finished product. Custom Die Casting Die casting is a metal manufacturing process that involves pressing molten metal under high pressure into a reusable metal mold. Die casting creates metal parts that are dimensionally accurate, well-defined, and have a smooth or textured surface. Commonly used in the manufacturing industry, die casting is a casting process that involves forcing molten metal through the cavity of a pre-shaped mold. Base metals such as zinc, aluminum, copper, magnesium and lead are first heated until they achieve a molten state. The newly molten metal is then forced i...

  Differences Installation ◑ Cast iron: This material offers the user many options when it comes to installation. Cast iron valves are typically flange bolted. Welding is difficult, but not impossible. Our cast iron valves are available with flanged ends, as this is an excellent method for high or low pressure applications. ◑ Ductile Iron:  Ductile iron offers many of the same installation options for the user  because of its similar construction to cast iron. Welding is not recommended, but bolting with flanges is still the best option for most applications.   Cost ◑ Cast Iron: The manufacturing process for cast iron valves is simpler than for ductile iron valves, which can save you a lot of money. If you don't need the additional benefits that ductile iron offers, cast iron is the smart choice. ◑ Ductile Iron: Ductile iron is the more expensive option, but for good reason. In many cases, it offers significantly better properties than cast iron.   Durability ◑ ...

Customers in all industries require a variety of valves to meet their demanding processes. Valves are available in a wide range of materials for any conceivable application. Some of these materials are PVC, carbon steel, stainless steel, cast iron, and ductile iron. This article focuses on cast iron valves and ductile iron valves.   Cast Iron Valves Cast iron (also known as gray cast iron) is a metal that has been used for centuries. Cast iron is strong and usually does not break even after severe vibration. It is an alloy made of 96-98% iron, 2%-4% carbon, and a small amount of silicone. It has impressive temperature tolerance, with some cast irons able to withstand temperatures in excess of 2100F (1150C). In terms of pressure, the strength of cast iron depends on its pressure rating. The two most common are Class 125 and Class 250. At less extreme temperatures, Class 125 cast iron flanges are rated between 150 and 200 psi. Class 250 cast iron is much harder and is rated from 300 ...

  304 An austenitic stainless steel with Ni content greater than 8%, a food grade alloy that can be used for casting domestic and commercial stainless steel parts. It is the most widely used stainless steel casting material.  304 stainless steel castings can be used in environments where air is less corrosive . Used in medical, food industry, chemical industry, mechanical equipment, piping industry, automotive industry, etc. 316 There are also austenitic stainless steels with a nickel content of more than 10%. Due to the higher Ni content, 316 stainless steel castings have better corrosion resistance than 304 stainless steel castings. Such stainless steel castings are more suitable for marine environments, where air conditions are relatively harsh, or where exposure to chemicals is required. Used in fire fighting, auto parts, marine hardware, chemical, piping, construction, decoration, food industry, etc. 304L / 316L Mechanical properties close to 304 and 316 materials. L repr...
