In industries such as thermal power, oil & gas, cement, and steel production, valve cages operate under extreme conditions — high temperature, high pressure, and continuous wear and corrosion. Over time, the surface of these components deteriorates, leading to reduced efficiency, safety risks, and higher maintenance costs. Common Problems of ...

The Importance of the Piston in a Hydraulic Breaker A hydraulic breaker (or hydraulic hammer) is a specialized attachment typically mounted on excavators, used for breaking rocks, concrete, or hard structures. Among its components, the piston plays a crucial role — transmitting the hydraulic energy directly to the chisel tip. ...

What is a Journal Bearing? A journal bearing (also known as a sleeve bearing) is a critical mechanical component used to support and guide rotating shafts in industrial machinery. Over time, the bearing surface is prone to wear, scratches, or cracks due to heavy loads, high rotational speeds, and harsh ...

In cement grinding plants, the gearbox gear is a critical component that operates under heavy load and continuous stress in harsh environments. Over time, the inner bore of the gear becomes worn, resulting in loss of precision, reduced performance, and shortened equipment lifespan. Laser Cladding Solution by PHUONGDONG INDUSTRY Inspection ...

During operation, bearing housings are often subjected to heavy loads and friction, leading to wear, pitting, cracking, or deformation. These issues reduce service life and negatively impact the overall performance of industrial equipment. At PHUONGDONG INDUSTRY, we apply advanced Laser Cladding technology to restore bearing housings with exceptional precision and ...

Why Do Injection Molds Need Surface Hardening? During the molding process, molds operate continuously under high pressure, friction, and thermal cycling. Critical areas such as cavity surfaces, edges, ribs, and pins are directly exposed to molten plastic and clamping forces, causing wear, deformation, and loss of dimensional accuracy over time.Therefore, ...

In industrial pump systems—especially in hydroelectric, thermal power, and oil & gas plants—the impeller plays a vital role in maintaining stable operation and high performance. During long-term use, impellers are exposed to abrasive particles, chemical corrosion, and cavitation, leading to surface wear, pitting, or cracking. These damages reduce pump efficiency, ...

During operation, grinding machine shafts often experience wear, cracks, or deformation caused by friction and heavy loads. Laser Cladding is a modern restoration solution that rebuilds the original geometry, strengthens the surface, and extends equipment lifespan. Advantages of Laser Cladding Technology High Precision: The coating layer is applied accurately and ...
