Products classified under HTS 8477.20.00.55
Micro Twin-Screw Extruder for Medical Tubing
This compact twin-screw extruder processes thermoplastics like polyethylene and nylon into precision medical tubing with diameters under 2mm. It features screws measuring 5.5 cm in diameter, classifying it under HTS 8477.20.0055 for extruders used in thermoplastic processing with screw size less than 6.4 cm. Ideal for high-precision applications in pharmaceutical packaging.
5cm Single-Screw Lab Extruder for Polymer Filaments
Laboratory-scale single-screw extruder with 5cm screw diameter for producing 3D printing filaments from PLA and ABS thermoplastics. Used in R&D for material development, it falls under HTS 8477.20.0055 due to its small screw size and thermoplastic processing capability. Produces uniform filaments with tight diameter tolerances.
Precision Micro-Extruder for Catheter Production
Ultra-precise single-screw extruder with 3.2cm screws for multilayer catheter tubing from medical-grade thermoplastics like Pebax. Meets stringent tolerances for biomedical applications, falling under HTS 8477.20.0055 due to small screw size for thermoplastic extrusion. Cleanroom compatible design.
4.5cm Desktop Filament Extruder for 3D Printing
Compact desktop extruder with 4.5cm screw for recycling thermoplastics into 1.75mm 3D printer filament. Designed for makerspaces and small businesses, classified under HTS 8477.20.0055 for small thermoplastic extruders. Features hopper dryer integration.
