SJ-35 / SJ-45 - Precision Filament
Product Description
Direct answer: This page targets buyers who prioritize filament dimensional control and repeatable feeding. Stable filament quality depends on material moisture, die design, melt temperature, cooling conditions, haul-off speed and winding tension. The laser gauge provides online measurement so the process can be adjusted against the confirmed target and tolerance.
Winsoar ABS PLA 3D printer filament extrusion machine is configured for stable diameter, surface quality and spool winding. The line combines material drying, single-screw plasticizing, precision die forming, staged cooling, online laser diameter measurement, servo haul-off and constant-tension winding for 1.75 mm, 2.85 mm and 3 mm filament.
ABS filament for functional prototypes, housings and mechanical parts
PLA filament for desktop printing, education and model production
1.75 mm, 2.85 mm and 3 mm filament product ranges
Brand-grade filament production requiring stable diameter and spool appearance
Prepare and dry the selected pellets according to the raw material supplier's moisture recommendation.
Melt, plasticize and homogenize the material in the single-screw extruder.
Form the filament through the selected die and establish the initial diameter.
Use staged cooling and sizing to control shrinkage, straightness and surface quality.
Measure diameter online and coordinate extrusion speed with haul-off speed.
Wind qualified filament onto spools with controlled tension for packing and shipment.
Online laser diameter measurement during continuous production
Synchronized extruder, haul-off and winder speed control
Staged cooling to reduce shrinkage, ovality and internal stress
Interchangeable die and process settings for common filament sizes
Controlled tension winding for clean spool edges and reliable unwinding
Configuration review based on material grade, output, tolerance and spool format
For a precision filament proposal, specify material grade, target diameter, tolerance, output, spool dimensions, winding tension requirements, color changes and local power standard.
For a complete multi-material configuration, see the 3D Printer Filament Production Line reference page.
Machine Configuration
The equipment is configured as a continuous filament process. The final screw, die, heating, cooling, laser, haul-off and winder selection depends on material, diameter, output, tolerance and spool requirements.
Main Technical Parameter
The following values are reference configurations for quotation. Final performance depends on material grade, formulation, die, process temperature, cooling conditions and quality standard.
| Item | SJ-35 | SJ-45 |
|---|---|---|
| Motor power | 5.5 kW | 15 kW |
| Reference output | 8-12 kg/h | 16-20 kg/h |
| Material | PLA, ABS and selected thermoplastic compounds | |
| Filament size | 1.75 mm, 2.85 mm and 3 mm, subject to die and process setup | |
| Diameter control | Online laser measurement; target tolerance confirmed against the buyer's standard | |
| Downstream | Servo haul-off, spool winding, inspection and export packing | |
For a precision filament proposal, specify material grade, target diameter, tolerance, output, spool dimensions, winding tension requirements, color changes and local power standard. Confirm the required factory length, operator access, cooling utilities and local electrical standard before final equipment selection.
Factory, Packaging & Exhibition
Winsoar supports filament equipment projects from material and product specification review through assembly, checking, export packaging, container loading and customer communication. The support images below show the project workflow around plastic extrusion equipment.
The workshop supports equipment assembly, electrical checking and line layout preparation before shipment.
Mechanical components, electrical controls, dies and accessories are checked against the confirmed project configuration.
Packaging is selected according to equipment dimensions, transport distance and unloading conditions.
Loading is organized to protect long equipment sections and smaller precision parts during overseas transport.
Technical discussions help confirm material, target diameter, output, spool format and factory conditions.
Filament samples help compare surface quality, diameter, color, spool winding and printing requirements.
For a precision filament proposal, specify material grade, target diameter, tolerance, output, spool dimensions, winding tension requirements, color changes and local power standard.
The line coordinates melt metering, staged cooling, online laser diameter measurement, servo haul-off and winding tension. These functions provide process feedback and stable traction, while the final tolerance still depends on the selected material, die and operating conditions.
The usual options are 1.75 mm, 2.85 mm and 3 mm with the corresponding die and process setup. The target diameter, tolerance and spool specification should be confirmed before ordering.
Carbon-fiber-filled, glass-fiber-filled and other modified compounds require a material review. Screw wear, drying, melt temperature, die design, cooling and cleaning procedures may need to be adjusted for the selected formulation.
Provide material grade, diameter, tolerance, target output, color or additive plan, spool format, local voltage and factory layout. This information allows the extruder, die, gauge, haul-off and winder to be matched as one system.
