Nickel Alloy Twin Screw Extruder Barrel for PEEK Plastic Extrusion

The barrel is a metal cylinder with openings at both ends, featuring a precisely machined interior cavity where the screw rotates. Constructed from high-strength, wear-resistant, and corrosion-resistant alloy steel, the inner wall undergoes special hardening treatment for enhanced durability.

• Accommodation and Molding: Provides a closed space and channel for the entire extrusion process (solid conveying, melting, mixing, homogenization, and venting), forming the final product shape through the die head at the outlet.
• Heat Exchange: One of the barrel's most crucial functions. Through an externally set heating and cooling system, it precisely controls material temperature, ensuring smooth plasticization (melting) and maintaining optimal processing conditions.
• Screw Interaction: The inner wall and screw groove surface create a shearing effect on materials. This relative motion between screw and stationary barrel enables material shearing, mixing, and compaction.
