3D filament extrusion lines

Two laboratory lines and four production lines. All run 1.75–3.0 mm filament; the difference is output and how many colours one machine can put into the strand.

Laboratory lines

For universities, material suppliers and factory R&D — small batches, quick colour changes, low material consumption.

HPSJ-3D-L Laboratory extrusion line
HPSJ-3D-L

Laboratory extrusion line

Bench-scale line for material trials and teaching.

HPSJ-3D-LW Laboratory extrusion line with accumulation unit
HPSJ-3D-LW

Laboratory extrusion line with accumulation unit

The same lab line, with a separate accumulator for steadier winding.

8–10 kg/h1.75–3.0 mm

Production lines

Four lines on one platform: single colour at 20–40 kg/h, dual and tricolour at 12–15 kg/h, gradient at 8–10 kg/h.
