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, ...

At PHUONG DONG, we are pioneers in applying advanced Laser Cladding technology to restore shafts and other critical machine components using specialized copper alloy powder. This provides an optimal solution for industries such as precision engineering, oil & gas, chemical processing, marine, and many other industrial sectors. Challenges of Copper ...

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 ...

The Wear Problem of Turbine Shaft Insert Ring in Hydropower Plants The turbine shaft insert ring is a critical component in hydropower turbine shafts. After long-term operation, it is often subjected to wear, scratches, or corrosion due to continuous friction and harsh working environments. This leads to leakage, reduced efficiency, ...

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 ...

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 ...
