Results indicate that processing with bar-stock as the blank will be better than that with stepped shafts in case of forming quality and volume of raw material, but requires larger forming force.
Most of the domestic enterprises take modular, semi-modular approaches and the crank and the journal are forged respectively.
Fig.1 Schematic diagram of full-grain-flow forging process 1.Crank throw 2.Crank journal 3.Main journal Characterized by continuous fiber and a reasonable distribution of the crankshaft, full fiber upset-bending forging technology greatly improves the crankshaft fatigue strength, increases metal utilization, reduces production cost, and is superior to freedom forging.
Among them, TR upset-bending forging process has been extensively used in making heavy crankshaft at home and abroad, because the continuous grain flow upset-bending process improve significantly the fatigue, material usage and machining productivity.

Edible plastics/films or biopolymers are biodegradable materials which are normally applied as food packaging.
This shows the potential of using these three types of polysaccharides as the biopolymer materials for the edible films [10].
Materials with a higher elongation at break percentage have higher ductility.
