Why is it necessary to repair high-pressure fan impeller shafts? The high-pressure fan shaft is a critical component in industrial fan systems, often installed in positions such as air supply fans, dust extraction fans, drying fans, and gas recirculation fans. These shafts are widely used in various mechanical engineering industries, ...

The rotor is a critical component of the Roots blower – a device commonly used in air supply systems for wastewater treatment plants, aquaculture facilities, food processing, cement production, textile, and dyeing industries. After prolonged operation, the shaft journals of the rotor often experience wear, scratches, or dimensional loss, directly ...

Broken or chipped teeth on large gears due to overload during operation is a common failure in heavy industries such as cement, steel, and mining. At Phuong Dong Industry, we apply Laser Cladding technology to restore damaged gears, offering a cost-effective and sustainable alternative to complete replacement. Outstanding Advantages of ...

Repairing small bores such as Ø70 is one of the most technically demanding challenges in precision mechanical restoration. With a narrow diameter and limited space, the process requires extremely high accuracy, along with precise control of the heat input and cladding thickness to ensure strong bonding and coating quality. Challenges ...

Laser Cladding is an advanced surface restoration and strengthening technology. It utilizes a high-energy, focused laser beam to melt metallic powder and fuse it with the base material surface. This process creates a dense, wear-resistant coating with excellent bonding and mechanical properties. Laser cladding is especially suitable for components subject ...

The rotor of a swing hammer crusher is subjected to severe wear and impact during the crushing of hard materials such as stone, clinker, slag, and ore. Over time, the hammer heads, throw arms, and rotor surfaces wear unevenly, leading to decreased crushing efficiency, rotor imbalance, and excessive vibration that ...

Piston heads made from aluminum alloy are widely used in automotive engines, compressors, and industrial equipment due to their lightweight, high thermal conductivity, and excellent heat resistance. However, during operation, piston heads are prone to wear, cracks, and deformation, which can negatively impact engine performance. PHUONGDONG INDUSTRY offers a high-precision ...

Laser cladding for inner bore repair of gear shafts (Ø30mm) is an optimal solution to restore worn, cracked, or deformed surfaces caused by industrial operation. At PHUONGDONG INDUSTRY, we apply advanced laser cladding technology to precisely restore the inner bore of gear shafts. The process creates a high-hardness alloy layer ...

Laser Cladding is increasingly used in the repair and surface enhancement of industrial components. For hollow parts such as cylinder bores, internal surface restoration presents a number of technical challenges due to space limitations and a high risk of thermal distortion, cracking, and coating delamination. Challenges in Internal Surface Cladding ...

1. Technology Overview Laser cladding with tin-based Babbitt alloy powder is an advanced surface coating technique that restores worn mechanical components such as journal bearings, bushings, and shaft supports. A high-power laser beam melts the Babbitt powder and fuses it metallurgically with the base material, forming a durable and uniform ...
