These days a customer asked me how to choose the right die casting tonnage is not die casting tonnage the bigger the better, so write this article slightly explain the die casting mold tonnage selection. Picture high pressure casting is a kind of pressure casting, in the case of high speed and high pressure liquid through the pressure chamber, by the die casting machine hammer into the mold internal molding, die casting machine tonnage the larger the pressure is mainly reflected in the clamping force, and die casting hammer. So how to judge the die casting products need the size of the tonnage? How to calculate the high pressure die casting tonnage, here we mainly from four aspects to consider: 1, calibration die casting products clamping force What is clamping force? Clamping force refers to, high pressure die casting products in the casting process, the molten metal liquid with high pressure into the mold cavity will produce a hold up the force, this time high pressure die casting machine exerted to the mold of...

Hot working includes casting, forging and welding. Cold working, also known as metal cutting process, including tool cutting process (which has turning process, drilling and boring process, planing, inserting, broaching, milling process, abrasive cutting process; the processing of gear teeth). The following are briefly introduced. (A) casting The casting process is to pour liquid metal into the mold, to be cooled to obtain a certain shape and sex of the casting. This is the method of molding metal in the liquid state. Casting can produce billet blanks of complex shapes, especially complex internal cavities, with unlimited size and weight. Both single-piece production, can also be mass production, the use of most of the material from a wide range of sources, low prices, but also available scrap and waste parts, so the cost is low. Castings and parts of the shape and size close to the processing allowance is small. Casting...
