The liquid metal molding process is called casting, poured into the liquid alloy in the mold of a good custom,When the temperature decreases the formation of molded castings.Sand casting, die casting, investment casting, shell casting, lost foam casting, low pressure casting, gravity casting is to distinguish according to the method of casting process.
By casting molding parts are generally valve castings, valve bonnet and hand wheel are such parts.Or greater cost savings are generally parts casting, design standards and meet the requirements of all premise.Forging and casting molding process is relatively molding process, generally on a smaller valve or special industry and specifically asked if the owners use.
Body, bonnet, stem, the valve (gate) is the main valve parts,in accordance with the requirements of the standard valve stem is forging,of course there because it can save some cost, using the rolling bar replaced,the valve used under low pressure experience doing this is acceptable.The stem (gate) and the valve body and bonnet as smaller is forging even bar direct processing it.Casting for some of the larger head. Our usual valve casting material is divided into: carbon steel, alloy steel and stainless steel. Carbon: WCA, WCB, WCC; alloy steel: WC6, WC9; Stainless Steel: CF8, CF8M, CF3, CF3M. Of course, these special materials copper, titanium, titanium alloy and so on will be used.
Forging metal blank is pressure by forging machinery to carry out, eventually causing the material to produce plastic deformation processing methods have mechanical properties, shape and size of forgings obtained. Stamping and forging belong to plastic processing properties, collectively forging.
Machinery manufacturing to forging common processing forming. Metal cast loose, the holes can be welded by forging methods to get rid of, as compared with the mechanical properties of the same general material castings forgings performance will be better. Mechanical load is high, the work demanding spares available rolled sheet, profiles or welded external shape, the rest of the use of forgings.
Q Are you a manufacturer or a trader?
