What is the reason why the casting flange is slightly higher than other flanges?

The production process of casting flanges. The casting process generally consists of the following steps: selecting high-quality billet blanking, heating, forming, and forging cooling. The casting process methods are free forging, die forging and film forging. At the time of production, different casting methods are selected according to the quality of the forgings and the number of batches produced.

Casting flanges have low yield and large machining allowance, but they are simple and versatile, so they are widely used for casting single-piece and small-sized forgings with simple shape. The self-forging equipment has air hammer, steam-air hammer and hydraulic press, which are suitable for the production of small, medium and large forgings respectively. The die forging yield is high, the operation is simple, and the mechanization and kinetics are simply completed. The die forgings have high dimensional accuracy, small machining allowance, and the fiber structure distribution of the forgings is more reasonable.

The basic process of casting flange: When casting, the shape of the forging is gradually forged by some fundamental deformation process. The basic processes of casting are upsetting, lengthening, punching, bending and blocking. Die forging is called model casting, and the heated billet is placed in a forging die fixed on a die forging machine.

The basic process of die forging process: blanking, heating, pre-forging, final forging, punching, trimming, quenching and tempering, shot peening. Commonly used processes are upsetting, lengthening, bending, punching, and forming. Common die forging equipment commonly used die forging equipment are die forging hammer, hot forging press, flat forging machine and friction press.

In a nutshell, the quality of the cast flange is better, generally produced by die forging, the crystal structure is fine, the strength is high, and of course the price is also more expensive. Both the casting flange and the casting flange are attributed to the common manufacturing method of the flange. See the strength requirements of the parts to be used. If the requirements are not high, the turning flange can also be selected.
