BL Flange manufacturers found that die forging is called model forging, which is formed by placing the heated blank in the forging die fixed on the die forging equipment.

1. The basic process of die forging for BL Flange manufacturers. Die forging process: blanking, heating, pre-forging, final forging, punching and skinning, edge trimming, quenching and tempering, shot peening. Common processes include upsetting, drawing, bending, punching and forming. 2. Commonly used die forging equipment Commonly used die forging equipment includes die forging hammers, hot die forging presses, flat forging machines and friction presses. In layman's terms, forged flanges are better in quality, generally produced by die forging, have fine crystal structure, high strength, and of course are more expensive. Both cast flanges and forged flanges are commonly used manufacturing methods for flanges. Depending on the strength requirements of the parts to be used, if the requirements are not high, turning flanges can also be used.

2. BL Flange manufacturers cut the flange: directly cut out the disc with the inner and outer diameter and thickness of the flange on the middle plate, and then process the bolt holes and waterline. The flange produced in this way is called a cut flange, and the maximum diameter of this type of flange is limited to the width of the middle plate.

3. BL Flange manufacturers Rolling flanges: The process of cutting strips with a middle plate and then rolling them into circles is called rolling, which is mostly used for the production of some large flanges. After the rolling is successful, it is welded, then flattened, and then the waterline and bolt holes are processed.
