This article aims to list the main sustainable practices developed in the processes of metal forming, casting, heat treatment, welding and electrostatic painting. When analysed the literature about sustainable manufacturing, a predominance of studies about machining is observed and the processes mentioned are few explored in academic studies. The research strategy used to reach the objective was systematic literature review, conducted for each process cited. Many sustainable practices were identified with prominence of better materials use and energy efficiency. The authors of this article believe that the information presented here can be useful for researches in their future studies and for industry professionals interested in improving manufacturing processes.

“…They introduced a method to manufacture sound blanks of acceptable size that used circular-and square-hole blanks instead of solid blanks. 13 In the deep-drawing process, sheets having a constant thickness are generally deep drawn. Various studies have been conducted to develop the deep-drawing method.…”

Deep drawing, one of the sheet metal forming processes, has a large area of use in industry. In the deep drawing, sheets having a fixed thickness are usually deep drawn. In general, there are some limitations, which prevent the part from being drawn at the desired depth, in the deep-drawing processes. Some of these consist of the increase in the sheet thickness towards the end of the part, being exposed to ironing, increasing wrinkles, exposure of the material to deformation hardening, and as a result, the fractures occur in the drawn part. Many special methods have been developed to increase the drawing height. One of them is to use blanks having machined edges. In the present study, the edges of the blank material were thinned by using the turning process at certain angles to avoid the above-mentioned negative effects. In this study, Al-1050 aluminum alloy with a thickness of 2 mm and machined edges of 1°, 2°, 3°, and 4° were used. The results were compared with the unmachined blanks. The highest drawing height was obtained with the blank having a 1° machined edge and 95 mm diameter. In addition, the power (approximately 7–31%) needed for deep drawing and material weight were reduced with the help of the deep-drawing process applied by using a specially manufactured blank.

“…Tailored blanks are blanks optimized to locally modify some properties of the sheet metal (thickness, material, etc.). Tailored blanks can be obtained by welding processes [4][5], using customrolled semi-finished products [6][7][8] or heat treated locally [9][10]. To prevent the welding process from causing distortion of the sheet and to partially reinforce the sheet itself, it is possible to add patches where required, using an adhesive bonding operation [11][12][13] before executing the forming process.…”

Lighter and lighter products are required by aerospace and automotive sectors in order to reduce fuel cost and carbon dioxide emissions and, to allow using green energy propulsion, such as the electric one. In order to lighten parts aluminium alloys, which have a high strength to weight ratio, are the most commonly used metal materials. They are manufactured through plastic deformation processes often by using tailored blanks. This work focuses the attention on semi-finished products obtained by subtracting material through machining; they are a further class of tailored blanks. In this work, the design of a simple (almost hemispherical) aluminium alloy sheet component in AA2017 aluminium alloy is analysed, with the help of finite element analysis. In order to reduce the component weight; a circular blank was used, characterised by a variable initial profile of the thickness instead of the conventional disc with a constant initial thickness. Given that a more uniform final thickness profile is determined, enhanced resistance characteristics of the product component are achieved. Therefore, the workpiece will be characterized by a weight reduction of about 8% compared to the analogous obtained from a blank with a constant initial thickness.
