Forging is an essential step in the production of valves at our D&R.
When producing metal products, it is difficult to turn the material into the target shape as the metal is solid. Therefore, we have to change the temperature of the metal.
The “forging” is actually a hot extrusion process. The mechanical properties of the valves after forging are good because the metal blanks are heated, extruded, and cooled after forging and their metal structure is changed, which improves the corrosion resistance of the valves.
