FAQ
Capacity is stated as extrusion output, not as a guaranteed finished-spool figure. For the documented high-speed configuration the extrusion output is up to 37 kg/h and is adjustable. Real throughput in service also depends on material, spool changeover and the shift pattern, so the figure is agreed with your own production target.
Diameter is measured in line with a dual-axis laser gauge at an accuracy of ±0.001 mm, so the operator sees the reading while the run is in progress. Extrusion temperature, screw speed, cooling conditions and traction speed are the process variables used to correct drift.
Extrusion output is the amount of material the extruder processes per hour. It is not the same as the packed weight of finished spools, because winding, spool changeover and downstream handling also affect the final usable output.
At the end of the line the winding station takes the finished filament and spools it under controlled tension. When the spool is full, the machine finishes the cycle and secures the filament end so the spool can be removed, packed or stacked without manual taping.
Next step
High-Speed
The RC-50 High-Speed 3D Filament Extrusion Line is a fully servo-controlled 3D printer filament production line designed to process materials such as PETG, ABS, PLA and PLA+ pellets into wound filament spools. It combines a 30:1 single-screw extruder with in-line laser diameter measurement, servo traction and automatic winding to support integrated filament production with reduced manual spool handling.
Standard-Speed
The RC-45 Standard-Speed 3D Filament Extrusion Line is a 3D printer filament production line for materials such as PLA, PLA+, PETG and ABS. It integrates extrusion, cooling, in-line diameter measurement, traction and automatic winding, with configuration options to match production targets, filament diameter and spool requirements.
