Forging Die Manufacturing Process. For forging dies manufacturing we provide you various options in die materials like high carbon high chromium die steels tool steels etc. What is Roll Forging. The required heating sleeves were determined for a maximum die temperature of 400 C. Impression die forging also known as closed die forging because each die set behaves a little like a pair of casting molds.
We all know that forging can be generally classified into two types open die forging and closed die forging. Once the process starts the impact of the top die on the metal material forms it into the required forged form. Metal coining is a forging process by which very fine and intricate details can be created on the surface of a work piece. For most forging processes a set of dies are required. Cogging is an open die forging process in which flat or slightly contoured die are employed to compress a work piece reducing its thickness and increasing its length. This is the temperature at which the workpiece or the material is about 75 of its melting temperature.
Cogging or drawing out is often used in manufacturing industry.
It is a type of closed die forging process in which pressure force is applied on the workpiece in a portion or entire surface is covered. The forging die was constructed in a tool guiding frame to ensure an optimal part quality within close manufacturing tolerance. Ideally the final configuration of the forging is developed in one blow or at most a few blows. Based on temperature the forging process can be broadly divided into hot forging or cold forging methods. Coining may be used to control surface quality and detail on parts. This process works by incorporating the shape of the forging into the top or bottom die as a negative image.
