The process of producing pistons is analyzed in the table below by example of two typical representatives of pistons: model 240-1004021 for D-240 compression ignition engine and model 21124-1004015 for VAZ-2112 spark-ignition engine.

The introduction of end-to-end designing system enabled the enterprise to produce new constructions of pistons that are characterized by less weight and altered geometry of friction surface
