Aluminum Forging

Forging is a metal production process with a long history. The advantage of forging production lies in the fact that it cannot only obtain the shape of mechanical parts but also improve the internal organization of materials and improve the mechanical properties. Due to the excellent performance of aluminum and aluminum alloys, it is widely used in machinery, electricity, electronics, automobile, ship, construction, instrumentation, hardware, and household products and other fields. Therefore, for important mechanical parts with high mechanical properties and high load capacity, they are mainly produced by forging aluminum. The weight of aluminum forgings represents 77% in aircraft, 68% in tanks and 76% in cars.

Forging production occupies a very important position in the industrial industry, aluminum alloy is also the material widely used in forging, all kinds of products that can be forged with low-carbon steel can be replaced by the aluminum forge. Most forged aluminum parts are safety parts and are produced in large quantities, so there is a high demand for the internal quality of aluminum materials. Aluminum forging generally follows these production processes: cutting - heating - forging - heat treatment - machining. Every procedure must be carefully monitored throughout the forging process.

Aluminum Forging Process

Aluminum alloys are produced by all currently available forging methods, including open die (or hand) forging, closed die forging, upset, roll forging and orbital (rotary) forging, rotary forging, mandrel forging, ring, and face rolling and reverse extrusion. The selection of the optimal forging method for a given forging mold is based on the forged mold desired, the refined design of the forged mold and the cost.

Most aluminum alloy forgings are produced in closed dies. The four types of closed die aluminum forgings are blocker type (only for forging finishes), conventional (only for forging blocks and finishing or finishing forging), high definition (almost clear shape produced by forging in one or more blocking dies followed by forging finish) and precision (no tensile, wire forming produced by forging with or without blocking dies followed by two or more stages of forging in the finishing dies). Blocker-type forgings are produced in relatively inexpensive die sets. In terms of dimensions and forged details, they are less refined and require more machining than conventional or high-definition closed-matrix forgings. A blocker-type forging costs less than a comparable conventional or high-definition forging, but it requires more machining.

Conventional closed die forging is the most common type of aluminum forging. They are produced with a single set of finishing dies or with block and finishing dies depending on the design criteria. Conventional forgings have less machine inventory and tighter tolerances than block forgings but require additional manufacturing costs, both for the additional die set and for the additional manufacturing steps required to produce this man. High definition forgings. With the advent of the forging press and advanced support equipment and improved control of the forging process discussed below, high definition forgings with a shape close to the wire can be produced. High definition cast forgings offer more refinement and tolerances in forging design than conventional or block forgings, further reducing the machining costs of the final components. High definition forgings are produced with several sets of dies consisting of one or more blocking dies and finishing dies and are often used in service with certain forged surfaces that are not machined by the purchaser.

Aluminum Forging Alloys

There are lots of aluminum alloys that can be used to Drop Forging. Main grades in aluminum forgings include AL6061, AL6063, AL6082, AL7075, etc.
