Phuong Dong has successfully completed a project to repair steam turbine blade tips using laser cladding technology at Pha Lai Thermal Power Plant 1, located in Hai Duong Province. This is one of the largest coal-fired power plants in Northern Vietnam, with a total installed capacity of 440 MW across ...

Turbine shaft restoration is a critical part of maintenance for hydropower generating units. At Ba Thuoc 1 Hydropower Plant (Thanh Hoa Province, Vietnam, with an installed capacity of ~60MW), the turbine shaft journal experienced severe wear after prolonged operation, posing risks to system performance and stability. To address the issue, ...

Laser Cladding Technology- Optimal Solution – Cost-effective – Prolongs Equipment Lifespan In steel rolling mills, the mandrel shaft plays a critical role in the coiling and uncoiling process. After prolonged operation, it often suffers from wear, cracks, or surface layer damage due to heavy load, high friction, and continuous work ...

1. Why Use Laser Cladding for Plastic Extrusion Cylinders? During continuous operation, plastic extrusion cylinders are exposed to high temperatures, intense pressure, and constant friction with the screw and molten material. Over time, the cylinder surface becomes worn, scratched, or corroded, leading to: Reduced product quality Increased energy consumption Leakage ...

1. Laser Hardening – The Most Advanced Heat Treatment Solution Today Laser Hardening is currently the most advanced surface heat treatment technology. It uses a highly controlled laser beam to heat specific areas on a component’s surface with exceptional precision. This technology is especially ideal for parts that require high ...

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 ...

A Pioneering Solution for Modern Industry In today’s manufacturing era, where precision, durability, and optimal performance are paramount, Laser Cladding technology has become the leading choice for surface treatment and mechanical part restoration. PHUONG DONG is proud to be a pioneer in Vietnam in researching, designing, and successfully manufacturing a dual-head ...

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 ...

Why is rotor repair necessary? The rotor is the central rotating component of a hydro generator, operating under heavy load and in harsh conditions. Over time, it often experiences: Surface wear at bearing or journal areas Cracks, pitting, or scratches due to friction and temperature Dimensional deviations affecting dynamic balance ...

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 ...
