PBO 600°C Seamless Felt Roller Sleeve for Aluminum Extrusion

The Ultimate Solution for Ultra-High Temperature Aluminum Handling

Our PBO 600°C Seamless Felt Roller Sleeves are specifically engineered for the most demanding stage of the aluminum extrusion process: the Initial Discharge Area. When aluminum profiles exit the die at temperatures exceeding 500°C, ordinary materials fail, soften, or mark the metal.

Yonghang’s PBO sleeves utilize a specialized needle-punching process to create a seamless, high-density structure. By combining 100% PBO fiber on the contact surface with a reinforced Kevlar base, we provide a roller sleeve that offers maximum thermal protection while maintaining cost-efficiency and mechanical durability.

Why choose our PBO Seamless Sleeves?

• Superior Heat Resistance: Capable of handling instantaneous temperatures up to 600°C without melting or degrading.

• True Seamless Technology: No joints, seams, or overlapping layers, ensuring a perfectly smooth profile surface without any "step marks."

• High-Density Hardening: Our unique hardening treatment increases wear resistance, preventing fibers from sticking to the hot aluminum.

• Dimensional Stability: Low shrinkage rates ensure the sleeve remains tight on the metal roller even under continuous high-heat cycles.

Product Application Range：

These sleeves are essential for any modern aluminum plant focused on high-quality surface finishes:

1. Lead-out Table / Initial Discharge: The primary location where aluminum exits the press.

2. Pick-up Zone: Handling the profile before it reaches the cooling table.

3. Run-out Tables: For heavy-duty industrial profiles and architectural aluminum that require zero-defect surfaces.

4. High-Spec Mechanical Parts: Ideal for transporting aerospace or automotive-grade aluminum components.
