【Al Forge Tech】Hot Forging Manufacturer : Top Hot Forging Process Solution

What is Hot Forging Process?

Hot Forging can be determined as “Applying immense and constant extrusion force on a moldable metal workpiece, usually a billet, to form said piece into a specified shape until the metal piece reaches around 75% of its melting temperature”. Hot forging components have a higher malleability, homogenized grain structure, and are porosity free.

Why Choose Hot Forging Process?

The melting point of unalloyed aluminum is 655℃, yet the whole hot forging process is kept at 300~500℃, under the melting point to assure best quality and strength throughout the whole manufacturing process, yet still allows some flexibility from the aluminum. Due to the high-temperature production process, workpieces are rather malleable during hammering/ pressing, as a result, this allows more sophisticated 3D forms. Customized aluminium forging is primarily manufactured by hot forging thanks to its high ductility nature. The outstanding and even surface provides multiple finishing work options which include: polishing, painting, coating, sandblasting, and anodizing, etc. As a professional hot forging manufacturer, we offer tailor-made to customers’ specified needs. Access to hot forging materials is fairly simple around the world, which brings a favorable impact on their global final price.

he main additional cost of hot forging process is applying heat, workpieces have to be heated to a high temperature, then returned to optimal working temperature for forging. This extra process builds up cost, and also pollutes the environment.

Since the workpiece is heated up then cooled down after forging, the cool down process has to be performed under specific conditions, or else it might cause the final product to warp and/ or bend due to uneven heat distribution. Therefore, extra attention will also be needed during the cool down process.

How to Hot Forge?

The hot forging process is as follows: High temperature (300~500℃ for Aluminum) is necessary as a means to prevent strain hardening of the metal deformation. Stamping is the most common way of hot forging, where the metal is hammered/ pressed between an upper and lower die surface.

Potential Cost Reductions in Hot Forging

First and foremost, reducing energy usage during the heating process of hot forging, perhaps optimizing individual heating process for each billet of different diameters to reduce energy consumption.

Implementing automatization during the forging procedure is another effective way to reduce cost: spraying mold release agent, swapping forge piece with a new billet, storing pieces in tidy and unified arrangement for transport, all these processes can be replaced by robots to greatly reduce the cost of manufacturing while increasing the safety level of factory workspace.
