Drop Forging Company

Information may not be reliable

CFS Forge is the professional drop forging manufacturer. Closed die forging process involves two dies, each containing a single impression or a series of multiple precision shapes cut into each die. Typically the bottom die is fixed in a set position and the upper die is raised some distance above the lower die. While the two dies are separated a controlled amount of material is heated to an exact temperature and positioned between the two die halves. When the two dies are brought together under extreme force, the material is deformed and forced to flow into the die impressions in a controlled manner. Any excess material present will flow through predetermined areas of the dies, called “Flash” and must be removed as a secondary operation.
