En 3200 avant JC, des moulages de grenouilles en bronze sont apparus en M\u00e9sopotamie. Entre le 13\u00e8me et le 10\u00e8me si\u00e8cle avant JC, la Chine est entr\u00e9e dans l&#039;apog\u00e9e des moulages en bronze, le processus a atteint un niveau assez \u00e9lev\u00e9, comme par exemple la dynastie Shang Simuwu carr\u00e9 Ding pesant 875 kg, la dynastie des Royaumes combattants Jinghou Yi Zunpan et la dynastie des Han occidentaux. Les miroirs transparents sont les produits repr\u00e9sentatifs de la fonte ancienne. Les premiers moulages ont \u00e9t\u00e9 fortement influenc\u00e9s par la poterie, et la plupart des moulages \u00e9taient des outils ou des ustensiles destin\u00e9s \u00e0 la production agricole, \u00e0 la religion, \u00e0 la vie et \u00e0 d&#039;autres aspects, avec une forte couleur artistique. En 513 avant JC, la Chine a produit la premi\u00e8re fonte au monde attest\u00e9e par \u00e9crit : la Jin Casting Ding (environ 270 kg). Vers le VIIIe si\u00e8cle, l\u2019Europe commence \u00e0 produire de la fonte. Apr\u00e8s la r\u00e9volution industrielle du XVIIIe si\u00e8cle, la fonderie entre dans une nouvelle p\u00e9riode au service des grandes industries. Au 20\u00e8me si\u00e8cle, le d\u00e9veloppement rapide du moulage a permis de d\u00e9velopper la fonte ductile, la fonte mall\u00e9able, l&#039;acier inoxydable \u00e0 tr\u00e8s faible teneur en carbone et le cuivre aluminium, l&#039;aluminium silicium, l&#039;alliage aluminium magn\u00e9sium, la base titane, l&#039;alliage base nickel et d&#039;autres mat\u00e9riaux m\u00e9talliques de coul\u00e9e, et a invent\u00e9 un nouveau proc\u00e9d\u00e9 pour la fonte grise pour r\u00e9aliser le traitement. Apr\u00e8s les ann\u00e9es 1950, de nouvelles technologies telles que le moulage \u00e0 haute pression au sable humide, le moulage au sable \u00e0 durcissement chimique, la fabrication de noyaux, le moulage \u00e0 pression n\u00e9gative et d&#039;autres moulages sp\u00e9ciaux et grenaillage ont \u00e9t\u00e9 introduits.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Types de moulage<\/h2>\n\n\n\n<p><span style=\"font-family: arial, helvetica, sans-serif; font-size: small;\">Il existe de nombreux types de casting.

reasons why you may want a forged ball valve for your application instead of a cast valve. Forged valves do tend to be better for high-temperature and high-pressure applications. These types of valves are less prone to thermal fatigue because the walls are thinner compared to cast alternatives. Also, forged options have a higher mass, making them mechanically stronger.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nHowever, there are a few reasons why a forged ball valve may not be best for your application. First, the forging process does create limitations for valve size and shape. Forging generally works better for smaller valves and components. In addition, not every metal is suitable for forging, which limits your options for valve material.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\nAdvantages and Disadvantages of Cast Valves\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nCast valves are a great option where you need quick turnaround and low-cost valves, as they require less labor to produce.

After cooling, solidification, and cleaning, a valve casting with a predetermined shape, size, and performance can be obtained. This is the entire casting valve crafting process. The connection between casting and valves came after the 20th century. Casting developed rapidly, creating ductile cast iron, malleable cast iron, ultra-low carbon stainless steel, aluminum copper, aluminum silicon, aluminum-magnesium alloy, and titanium which are still often used in valve products.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nCast metal materials such as base, nickel base alloy, etc. The main advantage of casting is that the cost of the blank produced by casting is low, and it can show its economy more for parts with complex shapes, especially with complex inner cavities. At the same time, it has wider adaptability and better comprehensive mechanical properties. However, many materials and equipment are required for casting production, and dust, harmful gases, and noise will be generated to pollute the environment.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nForged valve is a processing method that uses forging machinery to apply pressure to metal valve blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes, and sizes. Forging can be divided into open forging (free forging) and closed mode forging according to the forming method. According to the deformation temperature, forging can be divided into hot forging, warm forging, and cold forging.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nForging materials are mainly carbon steel and alloy steel with various compositions, followed by aluminum, magnesium, titanium, copper, etc., and their alloys. The original state of the material includes bar stock, ingot, metal powder, and liquid metal. The ratio of the cross-sectional area of the metal before deformation to the die cross-sectional area after deformation is called the forging ratio. Through forging, the as-cast looseness of metal and welding holes can be eliminated, and the mechanical properties of forgings are generally better than those of castings of the same material. For the important parts of machinery with high loads and severe working conditions, forgings are mostly used except for simpler shapes that can be rolled, profiles or welded parts. The correct selection of forging ratios has a great bearing on improving product quality and reducing costs.\r\n\r\n<!-- \/wp:paragraph -->","parent":0,"count":7,"filter":"raw"},{"term_id":3266,"name":"difference between forged and cast irons","slug":"difference-between-forged-and-cast-irons","term_group":0,"term_taxonomy_id":3266,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3263,"name":"forged vs cast","slug":"forged-vs-cast","term_group":0,"term_taxonomy_id":3263,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3264,"name":"Forged vs Cast Irons","slug":"forged-vs-cast-irons","term_group":0,"term_taxonomy_id":3264,"taxonomy":"post_tag","description":"<!-- wp:kadence\/tableofcontents {\"uniqueID\":\"_4feb50-82\"} \/-->\r\n\r\n<!-- wp:generateblocks\/button-container {\"uniqueId\":\"6d8495a3\",\"isDynamic\":true,\"blockVersion\":2} -->\r\n<!-- wp:generateblocks\/button {\"uniqueId\":\"3d442e11\",\"hasUrl\":true,\"target\":true,\"backgroundColor\":\"#0366d6\",\"textColor\":\"#ffffff\",\"backgroundColorHover\":\"#222222\",\"textColorHover\":\"#ffffff\",\"paddingTop\":\"15\",\"paddingRight\":\"20\",\"paddingBottom\":\"15\",\"paddingLeft\":\"20\"} -->\r\n<a class=\"gb-button gb-button-3d442e11 gb-button-text\" href=\"mailto:commercial@zecovalve.com\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>GET FORGED VS CAST IRONS INFORMATION<\/strong><\/a>\r\n<!-- \/wp:generateblocks\/button -->\r\n<!-- \/wp:generateblocks\/button-container -->\r\n\r\n<!-- wp:heading -->\r\n<h2 id=\"h-forged\">Forged<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nForging refers to a process in which a material is usually heated, while maintaining a solid state, and then forced into the shape desired. Now to explain better, we must put on our material engineering hats.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nMetals have a crystalline structure. You can think of it like wood. Wood has grains and those grains are oriented in a certain pattern. Therefore, the strength of wood depends on how those grains are oriented. For example, it is much easier to splinter a log for firewood when the grains are oriented vertically. Metal is the same way. If you examine metal under a microscope it will have the same grains that you associate with wood.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nWhen metal ingots are formed, special attention is made to creating a uniform and consistent crystalline structure. The grain sizes are similar and flow together. As previously stated, this maximizes the strength, consistency, and durability of the metal.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nNow when you forge something out of that metal ingot, you heat the ingot to make it malleable but not enough to break apart the crystalline grain structure. Think of a blacksmith. Blacksmiths heat metal till it's red hot and then form it on an anvil. This is forging. You do not see them melting the metal into a liquid. By keeping the metal, solid throughout the entire process, it ends up being a much stronger object. Therefore, swords, knives, etc. have historically been forged.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Cast Irons<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nCasting an object requires building a mold and pouring liquid metal into it. This process is great, as it allows for easy manufacturing and the creation of complex parts with hollow chambers such as with an engine block of a vehicle. The manufacturer can use a meltable material such as wax inside a sand mold to form these complex shapes.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nUnfortunately, once the metal becomes a liquid the crystalline grain structure breaks down. As a newly formed cast object cools down and becomes solid again, the grain structure reforms but this time much more randomly and inconsistently. There also is the potential for trapped air to create weak points. The metal becomes more like particle board or cardboard in terms of structure than a normal piece of wood.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nNow does this make cast parts weak? Absolutely not. Over the past couple thousand years, humans have gotten pretty good at making cast metal parts. Ventilation holes, vacuum pressure, and other advances increase the quality of cast metal. As stated, cast metal is what vehicle engine blocks are made from those are expected to withstand extreme stress and strain.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Manufacturing Process Forged vs Cast Irons<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe first thing to know is that \"cast\" and \"forged\" are nothing more than terms describing the manufacturing process of iron or a set of irons.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe casting process: When a golf iron is cast, the metal used to make the iron is heated to its melting point, becoming a liquid. It is then poured into the molds of the iron heads. When it cools and hardens, voila, you have golf irons.\r\nThe forging process: When a golf iron is forged, the solid metal of the club head is literally pounded or compressed until it takes the desired shape. After that, a number of other drilling and machining steps take place to finish the manufacturing process.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Forging is stronger than casting.<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nOne of the main reasons we choose to provide forging services is that it provides a stronger end product for our partners.

The production of shot blasting equipment in China began in the 1950s and was largely based on Soviet technology.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>What is Shot Blasting Machine Used For?<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nWheel blast machines can also be used to remove burrs, diaphragms, and rust that may affect the integrity, appearance, or definition of an object\u2019s parts. The machine can also target a partially coated surface to remove surface contaminants and provide a surface profile that increases the coating\u2019s adhesion to the surface for the purpose of shot-blasting the workpiece. A shot peening machine differs from a wheel blasting machine in that it is used to reduce the fatigue life of a part by increasing different surface stresses, increasing the strength of a part, or preventing micromotion. Shot blasting machines are primarily used to treat the surface of steel products in large quantities during the steel production process. The use of a shot blasting machine can effectively remove burrs on the surface of steel products, as well as some large-scale rust, in the use of shot blasting machines, if not mastering the technology, is likely to cause the integrity of the surface of steel products, the light will cause surface abrasions, and serious will cause a serious poor appearance, affecting the product image.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nFor steel production, a shot blasting machine is inevitable equipment, and the use of a shot blasting machine for steel sand as well as steel shot surface treatment, is also an essential process, as the removal of steel sand, steel shot surface stains, rust, and a necessary procedure to check the integrity of the product surface, is essential.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Functions of Shot Blasting Machine<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nCan remove the cast steel, cast iron surface of the oxide skin or sticky sand, the surface of the casting to play a role in cleaning, but also the quality of the castings for inspection of a necessary step, the large turbine casing to go in front of the line after shot blasting to detect injuries, so as to ensure reliable results.

The shot blast machine is used to throw 0.2 to 0.8 pellets to the surface of the workpiece, making the surface of the workpiece to a certain roughness, making the workpiece beautiful, or changing the compressive stress of the workpiece to improve the life of the workpiece. For the castings, shot blasting is the necessary process to discover the existence of the surface of the skin, the skin of the pores, and other defects, through shot blasting can ensure that the casting has a high quality.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nIn the modern theory of the strength of metals, as long as the density of the internal dislocation of the metal can be increased, the strength of the metal can be increased, and the use of a blasting machine blast to enhance the dislocation of the structure, which can help to improve the strength of the metal, this way is very effective for those who can not use the phase change of the hardened metal.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe shot-blasting can form compressive stress on the surface of the casting, which can make the castings of tensile strength, corrosion resistance, and fatigue strength have been enhanced, but also to correct those distorted thin-walled castings, can replace the ordinary hot and cold forming process, on large thin-walled castings to process, to avoid those residual tensile stress to obtain useful compressive stress.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Types of Shot Blasting Machines<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li>Sand blasting machine\r\n<ul>\r\n \t<li>Sandblasting machine uses abrasive and water, the benefit is dustless and mobile, suited for small, medium, and large size of all kind of material and shape, and manual with low capacity.<\/li>\r\n<\/ul>\r\n<\/li>\r\n \t<li>Tumble shot blasting machine with rubber conveyor\r\n<ul>\r\n \t<li>Shot blasting machine with rubber belt conveyor for treatment of casting pieces, suitable for the tumbling process.<\/li>\r\n<\/ul>\r\n<\/li>\r\n \t<li>Spinner-Hanger type shot blasting machine\r\n<ul>\r\n \t<li>Spinner-hanger type shot blasting machine with single or double hooks, manual loading either individually or in batches.<\/li>\r\n<\/ul>\r\n<\/li>\r\n \t<li>Monorail-continuous-hanger type shot blasting machine with carousel hooks system\r\n<ul>\r\n \t<li>The monorail-hanger type with more automatic and complex solutions than the spinner-hanger type shot blasting machine, which is equipped with an overhead handling system controlled by a PLC system.
