During hot pressing, the material is heated to an optimum temperature and then the workpiece is formed in a tool using, for example, a standard eccentric press. This is a fast process with a cycle time of about 2-4 seconds.
Benefits of hot pressing
Savings can often be made by using hot pressing in terms of both material and machine time. If there is a big difference between the biggest and smallest diameter of a workpiece, a lot of material is saved if it has already been turned. The cost of tooling is relatively low, which is also a major benefit.
Forging is the same process as hot pressing, but is usually performed using a hydraulic press or screw press. It takes longer, but has the same benefits such as saving material and machining time.
We have access to a Water Hydraulic Press.
