Superforming – Advances in Forming Technology
The recent trends in making lightweight cars that are resistant to require complex shaped alloys. Requiring the automotive industry to reduce the weight and costs of vehicles has pushed companies and second tier suppliers to make significant research and development investments geared towards forming new materials (Accudyne Engineering & Equipment Company 1). The resulting boron steel and aluminum alloys offer this desired improved safety and reduced weight. While it is an acceptable practice for companies to use advanced high steel, hot pressed boron steels, and other new equipment, sheet forming has taken on a new dimension within the twenty-first century. The speed of development in the automotive industry has brought in new overlapping technologies in materials and processes (Accudyne Engineering & Equipment Company 1; Advanced Manufacturing Office 1). Superforming is an overlap that includes traditional vacuum forming with plastic aluminum allots. The process has proved efficient in making excellent surface qualities with significant capital investments. With these developments in the automotive industry, advancements in superforming cannot fail to capture attention. Thus, the following review covers the latest developments in sheet form processes and highlights the advancements and trends in the sheet forming industry.
Background to the study
Superforming is a process that entails heating a single sheet of aluminum into a complex three-dimensional shape (Advanced Manufacturing Office 1). The aluminum is heated at hot pressures of 450 to 500 degrees Celsius before being cooled under air pressure into a surface tool. The superforming processes of cavity, bubble, black pressure and diaphragm create performed components that are manufactured into various aluminum alloys. Arias, William and Ridgway (2) assert that in automotive, the cavity, and the bubble forming processes are mostly applied depending on the end application. The component design is also a factor that determines the forming components used in making aluminium alloys (Arias, William & Ridgway 2). In automotive and rails, the 500 SPF alloy is applicable because of its ability to undergo various fabrication operations to create the desired part. In essence, the alloy offers all round performance and formability that is resistant to corrosion and suitable for making the further treatment. The fabrication operations that the performed components undergo are geared towards achieving an assembly before manufacture (Cora 2; Arias, William & Ridgway 2). The super form has various sophisticated processes that allow the aluminum sheet to be used in first stage operations. Later, the super form undergoes conventional trimming and edge hedging through conventional tooling as shown below.
