It was founded by Ali Sakalli with the name Proton Metal and started the sector as the production of Aluminum Ingots.in 2013, it entered the automotive sector with the production of diesel and gasoline engine pistons, compressor pistons and connecting rods and the company took its place in the automotive sector with the name Proton Piston.
Annular segments are located around the piston, which has a cylindrical structure. These rings allow the piston to fit into the cylinder, as well as prevent gases from leaking and oils from entering the chamber.
Alloy aluminum ingots are melted in natural gas furnaces and transferred to electric resting furnaces after January. Here, after degassing, grain thinning, slag removal operations are performed, casting into molds is performed.
Heat treatment is a process performed at high temperatures to give metals and alloys properties that they do not have. The metallic tension of the piston is provided in a homogeneous way, which ensures that the piston is easily processed on lathes and does not stick to the knife.
The pistons coming out of the heat treatment are processed in cnc lathe and cnc machining centers by going through processes such as rough, piston ring channel, pin slot, cell and sibop opening.
After all the processes are completed, the piston is processed with special egg-shaped dimensions with a special CNC oval machine and the piston is made ready to work in the piston shirt (cylinder).
The ovality measurements of the pistons coming out of the Finish are checked.
