The crankshaft is the most important part of the engine. It bears the force from the connecting rod and converts it into torque. It outputs through the crankshaft and drives other accessories on the engine. The crankshaft is subjected to the combined action of centrifugal force of rotating mass, periodic gas inertia force and reciprocating inertia force, which makes the crankshaft bear bending and torsion load. Therefore, the crankshaft is required to have sufficient strength and stiffness, and the journal surface needs to be wear-resistant, work evenly and have good balance.

HCVAC coating machine is applied to crankshaft parts. It is used in engineering parts of automobile and transportation industry. It has greatly improved wear resistance, extended service life and durability of components, and provided emergency operation reserve. The use of lighter materials and more compact design can reduce the overall weight and cost. The reduced friction loss can increase the power output and reduce the heat load of engine. The lower coating temperature avoids the shape or size Thanks to more than 100 coating centers all over the world, the delivery time is short and there are local experts' opinions.
