A cylindrical metal part that guides the piston to move in a straight line in a cylinder. Air in the engine cylinder through expansion of heat energy into mechanical energy; gas in the compressor cylinder by the piston compression and increase the pressure.

The shell of a turbine, rotary piston engine, etc. is often called a "cylinder". Application fields of cylinder: printing (tension control), semiconductor (spot welding machine, chip grinding), automatic control, robot, etc

HCVAC has more than 20 years of experience in coating cylinder parts and provides high-performance hard carbon based coatings that reduce friction and wear and improve power and reliability. The greatly improved wear resistance extends the service life and durability of components and provides emergency operation reserve. Using lighter materials and a more compact design can reduce overall weight and cost. The lower coating temperature avoids changes in shape or size and the need for finishing
