Filament extrusion lines
Filament lines built to run shift after shift.
HOPE has built plastic extrusion machinery in Foshan since 2002. The filament programme covers six lines: laboratory trials from 1 kg/h, production at 20–40 kg/h, and dual, tricolour and gradient versions of the same platform.
Laboratory, then production
Two laboratory lines for trials and teaching, four production lines for spool output. Same platform family, same control philosophy.
Laboratory extrusion line
Bench-scale line for material trials and teaching.
Laboratory extrusion line with accumulation unit
The same lab line, with a separate accumulator for steadier winding.
High-speed single-colour line
The workhorse: one colour, 20–40 kg/h.
Tricolour line
Three colours, or a three-layer core-sheath build.
What the line handles
One platform, three colour strategies
Single colour for volume. Dual or tricolour machines when the range needs effects, including two- and three-layer core-sheath filament by changing the die. The gradient line switches colour automatically every 6–8 m.
- Single, dual, tricolour and gradient — on the same frame family
- Two- and three-layer core-sheath builds by mould change
- Gradient line: automatic colour change every 6–8 m, feeding sequence adjustable
- Configuration and parameters adjusted to your material and target output
Materials
Compounds that run
The line is used with PLA, ABS, PETG, TPU and PA, and with filled or modified compounds. If you are running something outside that list, say so when you ask for a quotation — screw and temperature profiles are configured per material.
Filament size 1.75–3.0 mm across the range.
What we need to quote a line
Five answers are enough to come back with a configuration and a price.
- Material — PLA, ABS, PETG, TPU, PA or a filled compound
- Target output — kg per hour, or spools per shift
- Colour strategy — single, dual, tricolour or gradient
- Filament size — 1.75 mm, 3.0 mm, or both
- Site — voltage and frequency, and where the line ships
HOPE is part of a Foshan extrusion machinery group that builds more than thirty extruder families — medical tube, profiles, pipe, sheet, cable, foam and granulation. If your project is not filament, ask for the full catalogue.
