I do not know when you hear the two words of the process more of what we think of it, I think a lot of people on the pursuit of the process is mostly reflected in some of the above works of art. In fact, not only is the art of the requirements of the process is very high. In our field of machinery is also the process of excellence, because only a superb technology to create a more perfect product, for example, large diameter flange of its technological requirements is also very high.

Machining process is to cut the material into the required size, heating, forging, heat treatment, cleaning and inspection. In a small artificial forging, all these operations are carried out by several blacksmith overhand and underhand in narrow places, exposure to harmful environment and hazards in the same occupation; in large forging workshop, with the harm of different jobs. Moderate intensity physical labor, dry climate environment, produce noise and vibration of air polluted by smog.

Casting process is not as simple as we imagine, it is composed of many processes, the process of large diameter flange is composed of material selection, heating, forming, cooling. Every step has its specific requirements, will be especially hard, only each procedure done perfectly to forge a qualified forgings.
