Products classified under HTS 8477.20.00.05
Single Screw Extruder for Rubber Tires
A precision-engineered single screw component designed for extruders used in processing natural or synthetic rubber into tire treads and sidewalls. It falls under HTS 8477.20.00.05 as it is specifically for rubber thermosetting materials, facilitating uniform melting and shaping in extrusion lines. This part ensures high-volume production with consistent material flow.
Nitrided Single Screw for Thermoset Plastic Profiles
A nitrided steel single screw optimized for extruding thermosetting plastics like phenolic resins into profiles for electrical insulation. Classified under HTS 8477.20.00.05 due to its use in thermoset material processing equipment. The nitriding enhances wear resistance for high-temperature, abrasive thermoset extrusion.
High-Torque Single Screw for EPDM Rubber Seals
Engineered single screw for high-torque extruders processing EPDM rubber into weatherstripping and automotive seals. Falls under HTS 8477.20.00.05 for its role in thermosetting rubber extrusion machinery. Features deep channel geometry for shear-sensitive rubber compounds.
Barrier Single Screw for Melamine Extrusion
A barrier-type single screw for extruding melamine-formaldehyde thermoset resins into laminates and moldings. Classified in HTS 8477.20.00.05 for thermosetting plastics processing in dedicated extruders. The barrier design prevents resin degradation during high-heat extrusion.
Corrosion-Resistant Single Screw for Silicone Rubber Extrusion
A single screw with corrosion-resistant alloy coating for extruding liquid silicone rubber (LSR) into medical tubing and seals. It qualifies for HTS 8477.20.00.05 as it's engineered for thermosetting rubber processing in high-precision extruders. The design handles LSR's unique curing requirements during extrusion.
