Whether closed forging die or closed forging upsetting are very advantageous to the production of the head. Because the head produced by these two technologies doesn’t produce flash, the utilization rate of materials has been greatly improved. Exactly What kind of process is it, how will it have a good effect?

Through the use of closed forging die or closed upsetting die, it is possible to finish the finishing of the head with one or several processes; Moreover, since there is no flash, the force bearing area of the head will be reduced and the required load will be reduced. In order to achieve this goal, the material cannot be restricted, so the volume of the material and the relative position of the forging die should be strictly controlled to reduce wear.

Although free forging can also be used to form the head, the accuracy of the product is difficult to ensure due to the expansion of the material water from the vicinity of the mold face to the free surface during processing. If the direction of motion of the forging die and the swaging process can be controlled by computer technology, it is also possible to obtain a complicated shape and high precision head.
