Plungers are critical components in high-pressure pumps, responsible for generating suction and discharge pressure inside the cylinder chamber. Their performance directly affects pump efficiency, service stability, and overall equipment operation. During continuous reciprocating motion, plungers operate under high pressure, high friction, and corrosion environments. As industrial automation and continuous-production systems grow, plunger wear and corrosion become more severe—making advanced surface strengthening mandatory.

Danes laserska obloga has become the preferred technology for wear-resistant coating on plungers due to its exceptional hardness, metallurgical bonding, and extended component life.
