Restoring Plastic Extrusion Cylinders Using Laser Cladding Technology

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 or pressure loss during extrusion
• Damage to the screw or related components

Replacing a cylinder can be expensive and time-consuming. Laser Cladding is the optimal solution for restoring and extending the service life of extrusion cylinders while ensuring strict technical standards are maintained.

2. Outstanding Advantages of Laser Cladding Technology

Laser Cladding uses a high-powered laser beam to melt both the coating alloy powder and the base material surface, forming a strong metallurgical bond with excellent wear and heat resistance.

✅ Key Benefits:

• High precision: Restores original dimensions without affecting the core structure of the part
• Superior coating quality: Strong adhesion, high hardness, excellent wear resistance
• Minimal heat-affected zone (HAZ): Reduced thermal distortion and structural changes
• Cost savings: Restores used cylinders instead of replacing them with new ones

3. Laser Cladding Process for Plastic Extrusion Cylinders

At Phuong Dong Company, we follow a standard Laser Cladding process for restoring extrusion cylinders:

1. Disassembly and initial inspection
2. Preliminary machining to remove damaged areas
3. Laser Cladding with selected alloy materials
4. Final machining to restore precise dimensions
5. Quality inspection and acceptance testing

4. Practical Applications

We have successfully completed numerous projects restoring plastic extrusion barrels, especially in the following industries:

• Recycled plastics
• Engineering plastics
• HDPE and PVC pipe production
• Food processing, chemical, and rubber industries
